ITA Wealth Management readers will find James Montier’s paper, “Was It All Just A Bad Dream? Or, Ten Lessons Not Learnt” stimulating reading. At least parts of the paper are interesting. A few of his “Ten Lessons” are less than compelling. You do need to register (free) to gain access to the full paper. Or you can find it on my blog at this address.

On page two, under Lesson 2: Relative performance is a dangerous game, Montier references another paper by Cohen, Polk, and Silli. The Cohen et al paper will provide additional background for Montier’s positions. “They [Cohen et al] examined the ‘best ideas’ of US fund managers over the period 1991 to 2005. “Best Ideas” were measured as the biggest difference between the managers’ holdings and the weights of the index. The performance of these best ideas is impressive. Focusing on the top 25% of best ideas across the universe of active managers, Cohen, et al, find the average return is over 19% annually against a market return of 12% annually. That is to say, the stocks in which the managers displayed the most confidence outperformed the market by a significant amount.” Quoting Cohen et al on “Best Ideas,” – “We identify the “Best Ideas” of a manager as the stock with the highest tilt in his portfolio. Each of our four tilt measures proxies for the managerís relative conviction about his holdings. High tilt ranks indicate strong conviction.“ One does need to read the Cohen paper to gain a better understanding of their methods.
In the following paragraph, Montier writes, “The depressing corollary is that the other stocks they hold are dragging down their performance. Hence it appears that the focus on relative performance – and hence the fear of underperformance against an arbitrary benchmark – is a key source of underperformance.“
Now prepare yourself to take this shot as to why the money managers fail. According to Cohen et al, “The poor overall performance of mutual fund managers in the past is not due to a lack of stock-picking ability, but rather to institutional factors that encourage them to over-diversify.“
Montier continues to hammer the client with this quote – “Of course, this begs the question: why are fund managers so wedded to relative performance? The simple, although unpopular, answer is that clients and consultants force them to be.” In other words, blame the client for poor management of funds.
Within the last few days I posted references to the fact that active managers, by a wide percentage, fail to beat their benchmarks. Of course we know from William Sharpe’s papers, it is obvious why this is the case. What is difficult to explain is why this occurs to such a large percentage as shown in this article.
If you are on the board of a pension or endowment fund, and it is not matching or performing better than its benchmark, take solace in that fact that it is your fault and not your money managers stock selection process. Your expectations that they will beat their benchmark is holding them back as you are tying them to “relative performance.” This logic is positively amazing. Perhaps this is why the Cohen et al paper is still in draft form.
