Do lower-class mutual fund managers outperform those from wealthier backgrounds?

That is my latest Bloomberg column, here is one bit:

…new evidence on mutual fund managers suggests that the managers from poorer backgrounds beat the performance of wealthier peers. And it’s not a small effect: Managers from families in the bottom quintile of wealth appear to outperform those from families in the top quintile by 2.16 percent a year, in risk-adjusted terms.

That is one result from a new study by Oleg Chuprinin of University of New South Wales Business School and Denis Sosyura at the University of Michigan Business School.

Why might that be?:

Most individuals from less wealthy backgrounds don’t get to be mutual fund managers at all, and so as an entire class they do underperform. But if they do become fund managers, that may indicate superior smarts and hustle and eventually higher returns. Those from wealthier families, in contrast, maybe had to work less hard and be less smart to get those posts, and that may be reflected in their subsequent performance.

This hypothesis is supported by several features of the data.  For instance, the managers from wealthier families had a higher dispersion of returns. In other words, some of them did very, very well but others were lemons. That distribution is a classic sign of a relatively loose quality filter, and on strictly meritocratic grounds some of those managers probably didn’t deserve to be there.

Along those lines, the data show also that the fund managers from the wealthier families were more likely to receive promotions when their returns were subpar. The returns of the managers from the poorer families were much more tightly bunched, which is consistent with the notion that they passed through much tougher quality filters.

There are some relevant caveats, however, so do read the whole thing.
