Home Cooking and Value Investing - Why Careful Ingredient Selection and Patience Pays Off

Many would agree that the execution of a patiently prepared home-cooked meal with carefully selected ingredients is a rewarding endeavor. Pre-packaged takeaway is convenient, but is undesirable for many reasons, beyond any immediate satisfaction. 

Trends in investing are similar. Indices are essentially investment shopping lists prepared by someone else that help save passive investors time and effort in deciding what to buy or give benchmark-aware fund managers a starting point to help decide what to put in their trolleys. 

Changes in Investing Habits

Yet in 2017, the number of stock market indices exceeded the number of stocks in the US, expanding the proverbial supermarket of investment ‘takeaway’ offerings. 

What does it say about our investment eating habits when the number of shopping lists starts to exceed the number of actual ingredients to buy? In our rush to embrace convenience, are we losing sight of selecting quality underlying ingredients and carefully preparing healthy, well balanced portfolios?

Many products in the new financial supermarket are built on the assumptions and ‘theories’ of markets - that humans make rational economic decisions and that price should always reflect the intrinsic value of the investment. 

Yet humans, and therefore markets, are not perfectly rational, particularly in the short term. 

The 2017 Nobel Prize for Economics, awarded to Richard Thaler, recognised this as much, acknowledging his research which demonstrated “…that, unlike members of homo economicus, members of the species homo sapiens make predictable mistakes because of their use of heuristics, fallacies, and because of the way they are influenced by their social interactions.” (1)

Thaler demonstrates that humans, particularly investors:

  • rely too heavily on one trait or piece of information (anchoring), 
  • predict the frequency of an event based on how easily an example can be recalled (availability), 
  • judge probability of a theory by considering how much the theory resembles available data (representativeness), 
  • continue courses of action simply because that is how it has always been done (status quo), and 
  • are heavily influenced by the actions of others (herd mentality). 

Holding Period Returns

Value investing, like cooking, should be an exercise in careful selection, patience and conscious avoidance of biases. 

To this end, compelling research released last year from well-regarded active management academics Martijn Kremers and Ankur Pareek (2)  looked at the relationship between holding period (duration), degree of ‘activeness’ and returns for US fund managers (3). 

Kremers co-invented the concept of active share in 2009, which is now one of the pre-eminent ways of establishing whether an investment manager is a benchmark-hugger or takes high-conviction bets. 

A great deal of prior literature has shown that the long-term net performance of active managers is roughly similar to, or worse than, that of benchmark returns - on average

However, the authors find that Active Share, or the degree of difference between a fund’s holdings and its benchmark’s holdings, and the average holding periods of stocks in their portfolios, are key factors in determining the outperformance of both mutual funds and institutional portfolios. 

Unfortunately, such managers are the exception, not the rule.

Among high Active Share mutual funds, those with patient investment strategies (average holding periods of more than two years) appear to generate average alpha of 2.05% per year in the study

At the other end of the spectrum, irrespective of how dissimilar their portfolios are relative to their benchmarks, highly traded mutual funds with short stock holding periods underperform, with average annual net alpha of negative 1.44%. 

What lesson should we take from this study? Active investors must have conviction and be patient. What is good for us takes time to prepare and is best savored, not devoured! 

It thus comes as no surprise then, that the key to the success of high conviction, patient value investors is, funnily enough… valuation.

Valuations at time of entry remain key 

According to Bank of America Merrill Lynch analysis from 1971 to today - valuations at the time of purchase have explained 80-90% of returns from the S&P 500 over a 10-year horizon (4). The research, ironically, comes from a major investment bank, whom as an industry has prospered on encouraging short-term trading. 

True value investors should focus on valuation, rather than trying to keep up with the benchmark on a short-term basis as it maximises the chance of outperforming the market on a long-term basis.

This of course, is hard to justify to investment oversight committees where peer comparison and a natural human bias to immediate action prevails. As such, it is understandable why so much of the retail and institutional funds management industry trends towards career-risk driven mediocrity and hugs the benchmark. However, good investing, like good cooking, doesn’t benefit from having too many chefs in the kitchen. 

Patience ultimately wins over the long term, as too many investors trade too frequently, do not properly anchor assessments of value in fundamental long-term reasoning, or fire their fund managers too quickly. 

In the same way that cooking at home is harder and harder as we become more time poor, yet increasingly satisfying for the same reason, we believe patience and high conviction as sources of excess return is likely to persist due to the unchanging nature of human psychology. 

We are optimistic that growing investor short-termism and passive investing trends may, in fact, provide high conviction active investors with some of their best opportunities in a long time.

At Avenir Capital, we like to carefully and patiently prepare our own investment cooking and we encourage all investors to consider doing the same.
