New Decision Nerds Episode – Christmas Behaviour

Paul Richards and I downed some eggnog and decided to record an impromptu ‘Decision Nerds’ Christmas special. In the pod, we chat about how insights from behavioural science might help the holidays proceed more smoothly. This includes:

– Why I am worried that my Christmas gifts might make me look like an ‘egotistical a*&hole’.

– Why Paul sets very low expectations for Christmas.

– The nudges that retailers use to get us to buy.

– Gift cards or cash as a present – to constrain or not to constrain?

– Do New Year’s resolutions get a bad rap and how can we structure them to give a better chance of success?

Our favourite Christmas movie as a metaphor for decision-making and a gift that helps people understand their value to the world. (It’s not Die Hard).

Wherever you are, however you celebrate (or don’t), we hope that you have some high-quality time with family and friends over the festive period.

Christmas Behaviour

How Will Equity Markets Perform in 2024?

It is that time again when many investment professionals make predictions about how equity markets will perform over the coming 12 months. The only purpose of which seems to be allowing us to look back in a year’s time and comment on how pointless such endeavours are. Although it can be viewed as a harmless diversion, the pervasive culture of forecasting the unforecastable perpetuates damaging investor behaviour.

When setting expectations for equity markets for the year ahead, it is important to understand what it is actually being done. In simple terms, equity returns have three drivers – changes in valuation, dividend payments and earnings growth. Over short horizons it is often valuation changes (or what we might also call fluctuating sentiment) that dominate; whilst as the horizon extends it is cash flows and their growth that matters.

When we forecast the year ahead in equity markets, it is largely an exercise in anticipating changes in sentiment. In essence we are asking – how will the market (other investors) react to future events? Which is quite tricky.

If we are attempting to forecast equity market performance in 2024, we need to do three things:

1) Identify known issues or developments that will influence investor sentiment in 2024 and accurately predict them. (For example, we would need to know both that the action of The Fed will be influential and how they will behave).

2) Identify unknown issues that will influence investor sentiment in 2024 and correctly forecast them. (This is, by definition, impossible).

3) Foresee how markets will react to these known unknowns and unknown unknowns. (We don’t need to just get the events right, but the market’s reaction to them).

Although this may seem glib, it is not. It is exactly what is required to make such a forecast. It is a prediction of the market’s reaction to unpredictable events and events we haven’t even thought about.  

Given the improbability of meeting this challenge, why do so many people do it?

– It’s expected: Unfortunately, the most persuasive reason is that such short-termism is an unshakeable industry standard. I have worked in investment markets for twenty years and when people ask me about what I expect ‘the market’ to do next year I feel embarrassed saying “I have no idea”, even though it should be more embarrassing actually offering a confident forecast.

– It’s their job: For many people it is simply their job to produce such forecasts, whether they believe it has value or not.

– They believe it: Presumably some people believe there is merit in such forecasts, which I can only put down to overconfidence.

– It’s fun: Predicting short-term equity market performance is enjoyable and engaging. People want to keep doing things that are interesting and might keep doing them even if it destroys value over the long-run.

But what if we had to forecast equity market performance in 2024? What would be the ‘right’ way to do it? Probably by looking at some base rates of historic one year returns and perhaps adjusting those to reflect starting valuations. The final step would be to put some extraordinarily wide confidence intervals around the prediction, immediately rendering it pointless.

The truth is most people owning equities should be doing so to capture long-run returns by investing in a collection of companies generating a rising stream of real cash flows through time. Attempts to predict how the market might be pricing those cash flows over any given year is entirely fruitless and counterproductive. *

This is not simply a case of more wildly inaccurate forecasts in financial markets, but another example of the incessant implicit encouragement of damaging investor behaviour. The more we see these types of predictions, the more people think that equity markets are somehow stable rather than noisy, and that investing is about making short-run estimates of impossibly complex things.

We need to spend less time on spurious forecasts and more time on educating investors about what really matters.

How will equity markets perform in 2024? I have no idea.



* Even if we knew the ‘fair value’ of equity markets, there is no reason to believe that markets are ever attempting to ‘find’ this price. Why Should Equities Be Fairly Valued?

Why Do Investors Play Low Probability Games?

Being an investor is like walking into a casino and seeing everyone crowded around a table playing the game with the worst odds of success. We seem inexplicably drawn towards activities – such as timing the short-term fluctuations of markets or taking aggressive, concentrated bets – where the chances of positive outcomes are poor, yet we carry on regardless. Why can’t we resist playing what seem like the wrong games?

– We don’t know the odds of the game: We can either be oblivious to or wilfully ignorant of the probabilities attached to the activity we are undertaking. Although this is undoubtedly common, it shouldn’t be. Understanding the base rates of success should be the first thing we do.

– We have unusual skill in the game: Assuming we are playing for more than just entertainment, the only reason to engage in a game where the odds for the average player are poor is if we are uncommonly skilful.

– We are overconfident in our own abilities: The problem with believing that we are remarkably talented is that we probably aren’t. We are far more likely to have an unjustified, inflated view of our own capabilities and erroneously believe that the odds do not apply to us.

The game is exciting and fun to play: We play games where there is a high chance of failure if they are enjoyable, entertaining and engaging. The challenge for investors is that it is the boring stuff that works. And nobody wants to play a dull game.

– Lots of people are playing the game: If everyone else is involved in the game then we might as well join in. Not only is social proof important here (there is validation and comfort in doing the same as other people); but there becomes an expectation that we should be doing the same – we are an oddity if we don’t do it.

We get paid to play the game: If we are paid just for playing then the odds of success matter less.

The outcomes are asymmetric: Low probability games are attractive to play where we are able to capture a significant portion of the upside payoff, whilst other people bear the downside. (See hedge fund performance fees without clawbacks).

– There are more tables for this game: If a casino has 25 tables of low probability games that are fun to play, noisy and enticing, and a single table with a boring, quiet game with better odds of success – which one will we play? Almost certainly the former.

– We see other people winning at this game: We judge probabilities based not on the actual statistics – but what is available and salient. Huge coverage is granted to those fortunate enough to win big at low probability games and it makes us think that we can do it too. They make films and write books about the outliers and survivors in investing, not the average. 

As investors we spend far too much time focusing on how to win the game we are playing, rather than understanding the reasons we are playing at all.

What Happened in Financial Markets in the Second Quarter of 2019?

I have no idea what happened in financial markets in the second quarter of 2019. I think it is safe to assume that not many people do. The problem is that when we were living through it, it would have felt like the most important thing. As if the ‘information’ we were engaging with would have a profound impact on our investment outcomes. Yet now we cannot even remember it. Our obsession with dealing with what is right in front of us may well be an effective evolutionary adaption, but it is a terrible affliction for most investors with long-term goals.  

Human attention tends to be drawn towards two things – salience and availability. Salience is where something is particularly noticeable (often due to some emotional resonance), and availability is how easily something comes to mind (typically because it is recent). The lure of the day-to-day gyrations of financial markets is strong.

Unfortunately, it is not only an issue of attention, but importance. We are prone to hugely overweight the relevance of what is happening in the moment, as Daniel Kahneman noted:

“Nothing in life is as important as you think it is, while you are thinking about it.”

In the general sense this is not irrational human behaviour. If something is happening or changing in the current instant, then it can make absolute sense to focus on it and deal with it immediately. Taking the time to accurately calculate the probability of whether that movement you spotted on the savannah is actually the head of a lion is probably not a smart strategy. The issue is that rationality is context dependent. What is good for human survival is often terrible for long-term investing.

The problems that stem from this behavioural wiring are twofold. First, we are likely to neglect information that is genuinely important in favour of what we are currently experiencing. Second, we are almost certain to trade too much as we get stuck in the cycle of continually reacting to the next set of salient and available information, or what we might instead call the prevailing market narrative.

That most investors are caught in this behaviourally satisfying but return-eroding loop is reflected in the lack of introspection or reflection around past decisions and opinions. Nobody looks back at all the predictions that were made in our market outlooks for 2019 because it would be embarrassing to acknowledge how wrong we were and how attentively we focused on matters that were either irrelevant or unpredictable. It is better for everyone if we all just keep looking forward.

Escaping this damaging obsession with the present is not simply about overcoming our own behavioural limitations but acting in a manner that is contrary to expectations. It is not just us who feels that we must do something about what is happening right now. Everyone does. Even if we don’t think it is important it makes sense to act as if it is. In this instance taking action is still about survival, but not from the lion, in our job.

There are inevitably periods in time when there are market developments that matter for our long-term prospects. These might be fundamental (such as some significant change in valuations or expected returns) or behavioural (dealing with these challenges of bear markets and bubbles), but will be dramatically outweighed by things that are either unimportant or unforecastable. 

When we are living with markets in each moment it is almost impossible to separate signal from noise because of the undue status we place on the present. Aside from entirely ignoring the vacillations of markets (which for many is impossible), the only conceivable way to deal with this is to define in advance what aspects are important and then attempt to ignore the rest. This is the price of admission for the advantages provided by a long-term investing approach. Nobody said it was easy.

Attempting to be a long-term investor while obsessing over the short-term fluctuations of financial markets is like starting a diet but filling your kitchen with chocolates and cakes; you might still achieve your goals but you are really making it hard for yourself.

Diversification is Not a Free Lunch

Harry Markowitz is reported to have said that “diversification is the only free lunch in investing”. This is the notion that holding a broader range of assets can result in better returns without assuming more risk. Over the decades this has become accepted wisdom – but it is not true. Diversification isn’t free; it is painful and difficult to achieve.

Diversification is a vital concept for investors. It is an acceptance that the future is inherently unknowable and can take many different directions. If done well it provides protection against both uncertainty and hubris. The best indicator of an investor’s overconfidence is how concentrated their portfolio is. If we could accurately predict the future, then we would only own one security.

Given this, why is diversification a problem?

Because it is behaviourally difficult. To be appropriately diversified not only means holding assets that will be a disappointment, but where we actively want them to disappoint in advance.

If everything is performing well and in concert, our portfolios are probably not diversified.

If we are appropriately diversified, we will look at our portfolio and see a collection of strong performers and laggards. Rather than be comfortable with this as an inevitable feature of diversification however, we will have the urge to make changes. Removing the struggling positions and adding more to those that have produced stellar results.

It is far more comfortable for our portfolios to be focused on the top performing assets rather than be genuinely diversified. It will feel like there is nothing to worry about – everything is working well. Although we are drawn towards this type of situation, it is merely a short-term complacency that will foster almost certain long-term pain.

Diversification is constantly put in jeopardy by our behavioural failings. For the assets that are outperforming in our portfolios, the prevailing market narratives will persuade us that this environment will persist forever. Conversely, the stories around the stragglers will make us believe that they will never deliver again.

When we are reviewing the performance of our portfolio, diversification often feels like a bad idea – because we could have always held more of the assets that provided the highest returns.

Hindsight makes diversification look unnecessary.  

Given that maintaining appropriate levels of diversification is likely to prove a constant challenge for investors, there are two crucial concepts to place at the forefront of our thinking:

– Things will be different in the future: Markets are constantly adapting, things will be different in the future in ways that we are unable to predict.

– Things could have been different in the past: When we look at the performance of our portfolios, we assume that it was inescapable that this particular course had been charted, but, of course, this is never the case. In a chaotic, complex system, entirely different outcomes could have come to pass.

Diversification requires us to own positions that haven’t performed well and we don’t expect to always perform well. That doesn’t mean we should naively hold any asset irrespective of its fundamental characteristics, but we must accept that to be well-diversified requires us to have relative slackers in our portfolios at all points in time.

Nothing that works in investing provides a free lunch, it always comes with some behavioural pain. For diversification it is the acute sense of regret about how much better things could have been.

With the Best of Intentions

In those long-forgotten days when high quality bond yields were close to (or even below) zero, most investors longed for a return to a ‘normal’ environment. When a staple element of most multi-asset portfolios would once again provide an adequate return. For a time, it seemed that this day would never arrive and we would be in a permanent state of ‘return free risk’. Yet slowly and then suddenly everything changed. Bonds once again offered reasonable yields and provided genuine competition to other asset classes. And how did investors react to this much desired shift? By lamenting the losses incurred by bonds and questioning whether they are too risky to play a role as a conservative element of a diversified portfolio. Sometimes we are just never satisfied.

This shift in perspective on bonds highlights a major problem with investor behaviour. We have a tendency to make plans for future decisions – we will buy bonds when yields are higher or invest in equities after the next correction – but neglect to consider how we will actually feel when that time arrives. For bond yields to move higher or equities to get cheaper something has to happen, and that something is likely to make us not want to do it.

It is easy to form implementation intentions about the future, but far more difficult to apply them when we get there. This trait is apparent across all sorts of choices, not just investing – I will start going to the gym next week.

There are two major reasons for this behaviour:

1) Our future self is a far better person than our present self: Our future self is an incredible human being, unimpeachable and unaffected by any of the issues we are experiencing right now.

2) Things will be different in the future: There will be problems in the future – reasons not to act – that will only become apparent once we get there. From here it looks like clear water ahead, unfortunately that won’t be the case.

The second element is crucial for investors who make bold claims about waiting for better entry points into assets. These only arrive because developments shift the prevailing sentiment – they are a reaction to bad news – we will not be immune to this negativity.

When inflation was a non-existent problem and bonds had been in a bull market for decades, of course we hoped for an opportunity to buy in at higher yields – we just didn’t want anything else to change. Bonds paying nothing weren’t attractive, but perhaps the environment felt more comfortable.

We love the idea of buying cheaper assets, but blissfully ignore the pain required to get there and the difficulty of actually acting when they do.

Our present self is likely to staunchly disagree with our best laid plans when it finally comes to meet our future self asking: “what were you thinking, can’t you see how terrible everything is?”

How can we deal with our likely inability to enact future investment actions? There are several options:

– We shouldn’t make plans based on prices, yields or valuations; but think explicitly about what might happen for these to occur. These do not have to be precise forecasts about the future (because they will be wrong) but at least set reasonable expectations about the context in which a decision is likely to be made. If we want to invest in high yield bonds when spreads are historically wide, that will likely mean doing so in the midst of a deep recession, high unemployment and elevated default rates. Remember, bad things have to happen to get there. We should ask ourselves in advance – what is it that will make us not want to do this?

– Systematizing future actions is another powerful route. Most easily done through rebalancing, but also in more nuanced forms. By encoding systematic decisions we are acknowledging the likely divergence between our cool, rational forward-looking self and our hot state, in-the-moment, decision maker. Of course, it is important to remember that in times of stress we will likely try to ‘override the model’ and stop such systematic decisions, arguing that they don’t capture the gravity or nuance of the situation unfolding. In reality it will just be our emotions telling us not to do something inherently uncomfortable.



Despite our best intentions, when investors talk of making allocation decisions when there are better entry points or more attractive valuations, it is highly likely that when the time arrives we will be reluctant to follow the intended course of action. The narratives will be bleak, past performance poor and we will struggle to avoid extrapolating the pessimism.

We will be given every reason not to act and gladly accept them.

New Decision Nerds Episode – Seeing the Future

Although it is easy to be cynical about forecasting (as I often am), embedded in all of our decisions are predictions about the future. In the latest episode of Decision Nerds, Paul Richards and I explore the practicalities and pitfalls of making forecasts in highly uncertain environments with Professor Paul Goodwin. We discuss:

– The pros and cons of scenarios analysis.
– How individual forecasts compare those made by groups.
– The Delphi Technique.
– When we should tweak a model
– The lessons from superforecasting.

And much more in-between.

You can listen here: Seeing the Future

The Paradox of Past Performance

Although we may not like to admit it, the past performance of an asset class or fund is likely to have an overwhelming influence on our decision making.  We may try and mask the hold it has on us, but we are inescapably drawn towards investments with strong recent returns. The more pronounced and persistent the outperformance, the greater the pull. There is probably no more prevalent nor puzzling paradox in investing – in order to enhance our returns we make decisions based on a measure that is likely to reduce them.

The past performance of an asset are returns that we are not going to enjoy. They have been (at best) drawn forward from the future – the better the performance before we invest, the worse they will be after. Unusually strong returns are typically the result of unsustainable tailwinds, random doses of good luck and the inescapable swings of market sentiment.

Periods of abnormally strong performance mean that an investment has become more expensive and that it has earned higher returns than it is reasonable to expect on average. Both factors acting as a gravitational pull towards future disappointment.

This type of behaviour is most pronounced in active fund selection. Here it is not even an implicit driver of decision making, but rather an explicit feature of most processes. The popularity of star fund managers is (at least in part) forged on the notion that exceptional returns in the past are a prelude to exceptional returns in the future. We ignore the realities of valuations, the spectre of mean reversion, and fickle hand of fortune, and instead assume that some form of idiosyncratic skill will overcome all of these factors. This is an assumption with terrible odds of success.

The pull of past performance is not unique to fund manager selection, it is pervasive across the industry. We only need to look at the clamour for US equities following a decade (or more) of stellar performance. Investors seem to behave as if the market’s outsized returns in the recent past increase the probability of a continuation of this pattern, when in all likelihood the reverse should be true.

Why do we have such a strong tendency to read the wrong signal from past performance?

Extrapolation: We seemingly cannot avoid believing that trends of the recent past will persist, even when this view seems to be contrary to any rational analysis. A critical part of this anomalous behaviour is the power of storytelling. When assets or funds deliver exceptionally strong (or weak) performance, narratives are weaved to explain them. These compelling stories that justify unusual returns also bolster our belief that they will endure.  

Outcome Bias: Aside from our inescapable short-termism (more on that later), outcome bias is probably the most damaging behavioural foible suffered by investors. Whether it be for a stock, fund or asset class, when we witness strong performance we imbue that thing with some inherent goodness (and vice-versa). High past returns give us increasing confidence in the credentials of an investment. It must be good, haven’t you seen the returns?

Career Risk: For many, being in thrall to past performance is a survival strategy. Most professional investors make decisions to survive over the short-term. Although performance chasing might objectively appear to be an odd strategy at an aggregate level, for an individual it might be the best way to keep our job or avoid another difficult meeting. Investing in the in-vogue areas of the market can be both irrational and rational at the same time – it depends on our objective / incentive.

Instant / Delayed Gratification: Inherent in the paradoxical impact that past performance has on our decision making is the trade-off between instant and delayed gratification. We have an ingrained preference for doing things that make us feel better in the moment over waiting for rewards that may occur at some uncertain future point. Performance chasing gives us an instantaneous, positive hit – we are investing in areas of the market that are working right now, the stories supporting it are captivating and everyone thinks we are making a sensible call. The alternative approach gives us pain now with any benefit someway off in the distance.

One clear signal of the dangers innate in performance chasing is that there is no behavioural cost. It is easy to do and feels good when we do it. Almost all positive investment approaches come with behavioural pain – something has to hurt.



There is one important exception about the perils of making decisions based on past performance. The success of trend-following strategies, which are explicitly past performance focused. If there is evidence of this working, why is performance chasing such a problem? There is a critical distinction. The success of systematic trend-following strategies is about the consistent application of discipline and rules. Conversely, most investors engage in erratic trend-based investing (we invest in things because they have ‘gone up’) and rationalise the decision based on some post-hoc fundamental analysis.

We are largely secret trend-following investors not admitting how much past performance matters to ourselves or others, and absent the aspects that makes capturing such trends work. 

The paradox inherent in investors’ unhealthy focus on past performance does not mean that we should scour the market for the most egregious laggards, but rather be wary of the influence of high historic returns on our decisions and realistic about its likely consequences. Unusually strong past performance should make us concerned not confident.

The Curse of Short-Termism

In Chapter 12 of ‘The General Theory of Employment, Interest and Money’, John Maynard Keynes writes of the increasing short-term focus of investors, lamenting:

“Investment based on genuine long-term expectation is so difficult day to-day as to be scarcely practicable”.

Keynes’ seminal work was first published in 1936, so although it is easy to consider investor myopia as a modern phenomenon, it is not. Rather it is an ingrained feature of how humans engage with financial markets. That is not to say that the most pernicious problem faced by investors has not been exacerbated – the temptations are greater than ever – but simply that it is our default state. Unless we make a conscious effort to mitigate it, we will likely bear the heavy costs of short-termism.



The idea that adopting a long-term approach to investing can have a profound positive impact on our results can seem perverse. How can something so easy – doing less / paying less attention – lead to better outcomes? The critical misunderstanding here is the idea of simplicity. Long-termism is simple in theory but fiendishly difficult in practice. Everything from our psychological wiring to the broad environment in which we exist is dragging us toward making short-term choices. It takes considerable effort to extend our horizons.

Far from being easy, taking a long-term perspective is the most severe behavioural challenge that investors face.

Investing in the moment

Many of the decisions we make are a response to how we are feeling right now. Even when we think we are making a long-term choice, it is often a response to profound emotional stimulus. When we sell all of our risky assets in the teeth of a bear market we are relieving anxiety and fear – it feels good to do it at that moment. The cogent rationale we make for finally capitulating and buying stocks in the midst of a euphoric bubble is just a charade, what we are really doing is removing the stress and pressure of missing out. These types of feelings are smart from an evolutionary perspective – they helped us survive – they just make us terrible long-term investors.

It is not only our emotions and feelings that make us inveterate short-termists, but our inability to appropriately value long-term rewards. We are very poor at discounting and tend to give far more weight to near-term pay-offs than those that are stretched out far into the distance. We might be fully aware that staying invested is the best route to meeting our retirement goals thirty years hence, but the illusory lure of getting out of the market before the next crash might just prove too powerful.

Investing with a long-term mindset also requires us to ignore huge swathes of (potential) information. This is incredibly hard to do. We are being incessantly told that everything is changing, and we must respond to this by doing very little, which feels antithetical. A challenge exacerbated by the fact that what is happening in front of our eyes always feels like the most important thing. As Daniel Kahneman said:

“Nothing in life is as important as you think it is, while you are thinking of it”.

Taking a long-term approach means frequently ignoring issues that we and everyone believes – at that moment – are absolutely critical.  No wonder so few investors can do it.

Short-term is the norm

As if our own psychological foibles are not enough, there is another factor that makes it worse. Much worse. The environment in which we make investment decisions.

Most people are wired in the same way we are. We all want short-term gratification, so the investment industry is set-up to provide it. It is incredibly difficult to build a business or a career by saying: “Just wait thirty years and you will be okay”. If we want to get a promotion or sell an investment, then we need to be seen to be doing something. That almost always means taking a short-term view. We are incentivised to survive, and waiting for the long-term to play out is akin to a death wish.

Short-termism is not some elaborate profiteering plot, although it can feel like it, it is just the prevailing and powerful norm in investing. Everyone cares about it and lives by it, so everyone has to adopt that approach and play the game. Try saying we didn’t trade this quarter or last month’s performance was irrelevant and see how far that gets us.  

Nothing can stop us

If the Keynes quote at the beginning of this piece suggested that short-termism was nothing new, that is only partially true. There is a difference between our willingness and ability to be myopic. We were always willing but are now more able than ever.

There are two key elements that facilitate our short-termism. The amount of information available and the ease at which we can react to it. We are not inherently more short-term in our thinking than we used to be, but we are now faced with inescapable and overwhelming exposure to financial market noise – “7 seconds until the European market opens” – and can trade whenever we like. It is hard to think of a more toxic combination for provoking our worst investing behaviours. 

Technological innovations have been wonderful for investors, and also a behavioural disaster, inflaming our ingrained short-term predilections.

Say a lot, do a little

Are there any solutions? There are some. Not checking our portfolios or switching off financial news are likely positive steps toward better investment outcomes. But perhaps they are unrealistic. A more powerful approach might be an attempt to separate words from action.

Financial markets are incredibly diverting; they capture our attention and we cannot reasonably ignore them. Discussing them, however, should be entirely separate from taking active investment decisions.

One of the reasons that there is so much unnecessary and costly trading on portfolios is because investors feel like they must have something to talk about with clients. Trading creates narratives which creates comfort.  This plays to the notion that although tactical asset allocation doesn’t add value, it does help keep clients invested – because they feel happier that things are being looked after and it placates their desire to see short-term action.

Maybe this is inescapable, but if we want to enjoy the benefits of long-term investing, we need to find more ways of discussing financial markets without feeling compelled to constantly act.  

A long-term approach is (almost) always better

There is no greater advantage available to any investor than taking a longer-term approach. There is one important caveat, however. Long-termism is a great idea on the proviso that we make sensible decisions at the start. They don’t have to be heroic, they needn’t be optimal and there is no requirement for genius. Just some sensible choices and a long horizon will leave us better placed than most.

That’s far easier said than done.

What Matters?

One of the most profound problems encountered by investors is deciding what matters. We are faced with an incessant barrage of noise and must somehow parse relevant information from it; it’s like attempting to quench our thirst from a fire hydrant.

The oscillations of financial markets make us obsess over what matters right now: Why did the stock market lose 1.2% today? What is the Fed going to do at its next meeting? What are the major themes that will define markets over the next three years? This carousel of explanation and prediction is the lifeblood of the investment industry. It writes stories, it sells, it creates jobs, it shifts allocations. It constantly tells us what we need to get right in order to meet our goals.

As soon as you step into this world it is easy to be captured by this vortex – if we don’t care about the same things that everyone else does, then we are an outlier. Everyone is talking about (insert topic of the day) so we must be interested and have an opinion. If we want to be part of the game, maybe we just have to play it.   

Or maybe not.  

Focusing on the wrong things is not only exhausting, but it encourages the worst of our investing behaviours – what we think is an effort to add value is very likely to be destroying it. Instead of engaging in the search for the next critical fragment of information or attempting to predict, with high confidence, the next meaningful variable, we should take a different approach and ask – what really matters? 

For it to matter to us, there are two questions we should always ask ourselves about a variable or piece of information we are considering:

– How influential is it likely to be in meeting my objective?

– How knowable or predictable is it?

For information to matter to enough for us to take an explicit view on it, we need two things to hold – we must be confident that it will impact the outcome we are seeking (usually returns) and be comfortable that either the information is already available, or we can accurately forecast it.

Let’s take some examples. Imagine we believe that the level of real yields will be influential for equity returns over the next three years; it is not sufficient to consider it an important variable, we need to believe that we can predict it with a reasonable level of confidence. If we assume that we cannot do this, then the level of real yields is not something that matters enough for us to take a high conviction view on – aside from being appropriately diversified across a range of potential outcomes.

Now assume we are a long-term (10 years +) investor and believe that valuation will be a key determinant of returns over our time horizon. In this scenario, both questions can be answered in the affirmative. The price we pay for an asset is more influential for the long-term returns we receive than anything else, and we know it with reasonable confidence in advance.

There is a caveat, however. If, in the valuation example, we contracted our time horizon – let’s say to one year – valuations would fail the test; although they are knowable, they are just not that influential over the short-run. Being clear about precisely what we are trying to achieve is critical in defining what should matter to our decision making.

The reason that short-term market predictions are so difficult to make is that we do not know what the most influential variables are likely to be (what market participants will care about tomorrow), nor – by definition – can we predict them. For short-term market forecasts everything and nothing matters.

For most investors there are two types of variables, dull and predictable ones (valuation, time horizons etc…) which always tend to matter over the long-run, and exciting and volatile ones, which tend to receive all the attention. This is understandable. Unpredictable variables are changeable, exciting and dominate our thinking. They allow us to weave compelling narratives and express distinctive views. It is hard to forge a career focusing on what everyone already knows and ignoring what everyone is talking about.

A huge host of things influence the short-term price movements in markets and this creates profound behavioural challenges; inevitably leading to erratic decision making and a loss of attention on what is important. A key first principle for all investors should be to define at the outset what factors matter most for us given our objectives. If we focus on these, it might just give us a fighting chance of cancelling out the noise.
