Regulators take note: New research finds mutual fund managers do better, not worse, when they also manage “side-by-side” hedge funds
Mar 15th, 2010 | Filed under: Retail Investing, Today's Post
Popular mythology often tells the tale of a disgruntled mutual fund manager who strikes out on his or her own and starts a (more lucrative) hedge fund business. The existing hedge fund community often retorts that mutual fund managers simply don’t have the training (read “short selling”) experience to manage a hedge fund.
Is this just marketing bravado? Or is it true that mutual fund managers are no good at managing hedge funds.
More importantly for policy makers, does a mutual fund manager do a disservice to their investors by running a hedge fund on the side? After all, wouldn’t the much lauded “alignment of interests” inherent in hedge fund contracts give the manager an incentive to funnel their best trades and ideas to the “2 and 20″ hedge fund?
Counter-intuitively, a new study by Tom Nohel of Loyola University, Z. Jay Wang of the University of Illinois and Lu Zheng of UC Irvine actually concludes that managers of “side-by-side” hedge funds and mutual funds actually tend to deliver better mutual fund returns than those who manage only mutual funds. In other words, the possibility of nefarious trade allocations invoked by hedge fund antagonists is not only a red herring, but the exact opposite may be true.
Regular readers may recall this 2006 study by Gjergji Cici, Scott Gibson, and Rabih Moussawi that shows that companies (not managers themselves) that provide both hedge funds and mutual funds tend to deliver lower mutual fund returns. To explain this phenomenon, Cici et al outline 6 potential conflicts of interest faced by these companies (front running, trade allocations, soft dollars etc.)
AllAboutAlpha-philes may also remember this paper on “hedged mutual funds” by Vikas Agarwal, Nicole Boyson, and Narayan Naik. Agarwal, Boyson and Naik found that mutual fund companies running hedge funds in mutual fund wrappers deliver sub-par returns unless they also run a bona fide hedge fund.
This new study seems to conflict with Cici et al and, to some extent, support Agarwal et al’s finding that managing a hedge fund on the side is good for mutual fund unit holders.
In any event, the authors of the new study create a portfolio of mutual funds managed by “side-by-side” managers (those managing both mutual and hedge funds) and a portfolio of mutual funds managed by individuals whose sole focus is the mutual fund. Similarly, they create a portfolio of hedge funds managed by “side-by-side” managers and one of hedge funds managed by pure-play hedge fund managers.
When they compared the 4-factor alphas of the mutual fund portfolios and 7-factor alphas of the hedge fund portfolios, here’s what they found:
Ironically, the mutual funds managed by those individuals who also managed a hedge fund produced better returns than those managed by mutual fund managers who did not also manage a hedge fund. So much for conflicts of interest, we suppose.
In fact, regulators might take note that it’s the high net worth hedge fund investors, not the mom and pop mutual fund investors that are worse off when mutual fund managers stray into Hedgistan.
So why would a mutual managed by the same person simultaneously managing a hedge fund do better than their more focused industry colleagues? Nohel, Wang and Zheng have a few theories…
First and foremost, they suggest that the theory that the hedge fund industry attracts high talent may have some legs. Writes the trio:
“Our evidence supports the idea that the privilege of running a hedge fund is primarily granted to the most skilled mutual fund managers, especially given that the superior performance we document is driven by managers whose careers began in the mutual fund industry.”
In other words, an opportunity to manage a hedge fund is being used as “means of retention” by mutual fund companies.
They also hypothesize that when mutual fund managers start managing hedge funds on the side, any incentive to funnel trades and ideas to the higher-fee hedge fund is mitigates by the concern for losing their reputations as stellar mutual fund managers.
But rest assured, hedge fund marketers, this study found that “side-by-side” hedge fund managers that came from the mutual fund world delivered lower hedge fund returns than those managers who cut their teeth on hedge funds…
“…those that began as hedge fund managers had insignificant alphas of 0.081% per month relative to their peers, while those that began as mutual fund managers significantly underperformed their peers by -0.282%.”
But wait. It also turns out that mutual funds managed by “side-by-side” managers from the mutual fund industry performed better than mutual funds managed by managers from the hedge fund industry…
“…side-by-side managers that began as mutual fund managers generated alphas of 0.094% per month or about 1.13% per year and highly significant, while side-by-side managers who began their careers as hedge fund managers generated insignificant alphas of 0.01% per month.”
So the somewhat anti-climatic conclusion is sure to please both camps: Mutual fund managers deliver better mutual fund returns, and hedge fund managers deliver better hedge fund returns.
A final note: Check out table 2 of the paper, comparing the characteristics of side-by-side and pure play mutual funds. The side-by-side funds are: smaller, more expensive, and have a higher turn-over than the pure play funds. That makes intuitive sense if you believe the “hedge fund culture” might work its way into mutual fund terms.
But what is somewhat surprising is that side-by-side hedge funds have a higher performance fee and a longer lock-up than pure play hedge funds. (Although as you might guess, they have a lower management fee than pure play hedge funds.)

The “Resistance”
Despite the aversion retail investors have recently had to hedge funds, the hedgification of traditional investments is apparently continuing in some quarters of the money management business.
With many investors now convinced that markets will trade sideways for some time, they say beta returns should be forsaken in favour of alpha-centric returns. Meanwhile, emboldened by what they see as a fire sale in equities, many other are increasing their equity beta exposure right now. As a result, the age-old tug-o-war between active and passive management seems to have moved back to the front pages.
