Is there a whelk in your fund portfolio?

 

By LARRY SWEDROE

 

You may never have heard of a whelk. However, this little ocean creature can ruin an oyster’s day. A whelk looks like a conch, only a bit smaller. It’s equipped with a tentacle that works like an auger. The little whelk will drill a very small hole in the top of the oyster’s shell. Through this very small hole, a whelk can devour an entire oyster, sucking it out little by little until the oyster is gone.

Tim Mooney, D.K. Malhotra and Philip Russell, authors of the study Advisory Fee and Mutual Fund Returns, published in the Winter 2020 issue of The Journal of Index Investing, demonstrated that mutual fund expenses are the little whelks doing damage to your portfolio. Their study sought to determine if there is a link between the expense ratio of a fund and its returns by analysing the advisory fees of 945 mutual funds and their 12-month returns over the period 2000-2017.

The authors began by noting: “Mutual fund investors should be willing to pay a higher management fee to get a superior rate of return. But if there is no causality between advisory fee and fund performance, then mutual fund investors are better off looking for funds with a lower management fee.”

Following is a summary of their findings:

— There was a secular trend of declining advisory fees across the sample period — from 0.77 percent to 0.67 percent, a drop of 13 percent. 

— The correlation between turnover ratio and returns was negative and statistically significant — increased turnover resulted in lower 12-month total returns.

— Market timing was negatively related to returns.

— There was no evidence that higher advisory fees are consistent with greater portfolio manager skill — paying more for advisory services in exchange for higher fund returns is not worth it.

 

Markets are competitive

Their finding that higher fund advisory fees do not translate into higher net returns to investors lends support to the model proposed by Jonathan Berk and Richard Green in their 2004 paper, Mutual Fund Flows and Performance in Rational Markets. Berk and Green explain that, in their model:

“Investments with active managers do not outperform passive benchmarks because investors competitively supply funds to managers and there are decreasing returns for managers in deploying their superior ability. Managers increase the size of their funds, and their own compensation, to the point at which expected returns to investors are competitive going forward.

“The failure of managers as a group to outperform passive benchmarks does not imply that they lack skill. Furthermore, the lack of persistence does not imply that differential ability across managers is unrewarded, that gathering information about performance is socially wasteful, or that chasing performance is pointless. It merely implies that the provision of capital by investors to the mutual fund industry is competitive.”

 

Superior performance cannot be predictable

Berk and Green continued:

“Performance is not persistent in the model precisely because investors chase performance and make full, rational use of information about funds’ histories in doing so. High performance is rationally interpreted by investors as evidence of the manager’s superior ability. New money flows to the fund to the point at which expected excess returns going forward are competitive.

“This process necessarily implies that investors cannot expect to make positive excess returns, so superior performance cannot be predictable. The response of fund flows to performance is simply evidence that capital flows to investments in which it is most productive.”

 

Expected excess returns must be zero

In his 2005 paper, Five Myths of Active Portfolio Management, Jonathan Berk also explained why, even in the presence of skilled active managers, investors should not expect to benefit from that skill. This is what he said:

“When capital is supplied competitively by investors, but ability is scarce, only participants with the skill in short supply (the skilled active managers) can earn economic rents.

“Investors who choose to invest with active managers cannot expect to receive positive excess returns on a risk-adjusted basis. In any economy with rational profit-maximising investors who compete with each other, all expected risk-adjusted excess returns must be zero, and realized excess returns must be unpredictable.”

 

They don’t call it the loser’s game for nothing

The bottom line is that while the research finds that there are active managers skilled enough to generate gross alphas, the whelks in portfolio (in the form of advisory fees as well as turnover costs) more than erode the benefits of the skilled manager, leaving investors with net negative alphas. That makes active management the loser’s game.
