We’re now in the longest bull market of all-time, at least in modern history. The S&P 500 has not only made new highs, it’s done so without falling more than 20% for more than 115 months, with the previous record having been set during the great expansion of the 1990s.
But here’s my question: have investors benefitted as much as they should have?
The answer is clearly no in aggregate. The performance of many active managers has been disappointing, particularly after February 2014. While there are many explanations for this, my own opinion is that underperformance is generally attributable to emotions, time-horizon and rational behaviour. This is my qualitative judgement rather than scientific or statistical fact, but I think it offers us a useful framework to evaluate active performance.
Let’s start by assessing the emotional aspect to all this. It’s clear to me that professional stock pickers are trying to beat the market with empirically backed philosophies. Furthermore, most of them have a relatively good understanding of balance sheets and income statements, a repeatable process to ensure consistency, and can combine their ideas into a reasonably robust portfolio.
The problem is they’re ‘active’, and with this comes the emotional connection that something has to be done. That is a dangerous emotion to have in a bull market built on a momentum, when often the best choice is to do nothing. It’s difficult emotionally not to take profits from your winners, not to buy more of your underperformers and most of all, to explain to clients why you’re not doing anything. Something must be done are often the four most dangerous words in investing.
Confusingly, most managers think their key competitive advantage is ‘time horizon’. Yet if everyone’s ‘competitive advantage’ is time-horizon, it’s clearly not an advantage anymore. In active management, long term can be anything from two to five years. Very few think in terms of decades, and even fewer would actually hold their highest conviction investments for that long – and definitely not without taking profits or buying more at some point.
The last factor – rational behaviour – wouldn’t make most people’s list of reasons why active managers underperform, but it’s undeniable. Sir John Templeton was one of the first to point out this factor when he said: ‘the market can remain irrational a lot longer than most investors can remain liquid’.
If you buy your stock when it’s trading at 60 cents to the dollar, the theory goes you sell it at $1. Maybe run it to $1.20. But few investors would not at least take profits, if not sell completely when $1.50 arrives. My point is, it’s quite rational to sell a liquid investment when valuations reach what you believe is relatively excessive.
For people running their own investment portfolios, however, the news is even worse. Asset weighted returns are generally worse than time weighted returns. Put another way, investor experience in mutual funds is significantly worse than the actual mutual fund performance.
If portfolio managers are not really long term, end investors tend to be even less so. Fund investors tend to buy high and sell low – you can see this by comparing the performance of active funds and their inflows. The general trend when funds outperform is for investors to realise this only belatedly, and start adding once rolling outperformance begins to fade.
In order to maximise the long-term benefits of active management, we probably need to redefine what long term is. While a longer time horizon in itself is not a competitive advantage, it at least allows the opportunity to maximise investment returns, rather than trying to time the market.
Related to that, we also need to understand that a bull market is not a full cycle. While a skilful and rational investor should outperform over a full cycle, they may struggle at some parts of the cycle. While underperformance over a shorter time horizon might be disappointing, it’s important to remember that past performance in itself is never a reason to make a decision about future outcomes.
