Hi Guys,
The referenced article is indeed excellent. However, it really contains no surprising information. It just reinforces a wide body of earlier research findings that grow more compelling with each year’s additional data.
Mutual fund performance persistence is largely a myth, with a few outstanding exceptions. The game plan should be to find and stick with those noteworthy exceptions. The article identifies a few of them.
In physics, the law of gravity dominates. Although not quite as universal, within the investment community, a regression-to-the-mean law seems almost as pervasive.
The evidence against fund persistent outperformance is overwhelming. In its early
years, the Morningstar 5-star rating system proved so vulnerable to performance decay, and subsequently to star erosion, that the firm was forced to modify and expand its ranking methods to salvage its fading reputation.
The numerous periodic table of returns published annually by a host of industry giants demonstrate the fragile nature of last year’s winners. The rotations are swift. Buying last year’s top performers has proven to be a Loser’s game.
Each year, Fortune magazine issues a list of the most respected and the most despised companies. The list does have some stability year over year. However, the market returns from owning the most accomplished companies over the long haul do not match those yielded by the least honored outfits. From an investment rewards perspective, this is yet another illustration of a regression-to-the-mean pull.
All MFO regulars should be familiar with the often referenced Standard and Poor’s SPIVA and Persistency reports. These documents have registered fund persistency failures for many
years. Here is the Link to those data rich reports:

Michael Mauboussin has written extensively about the tradeoffs between luck and skill in determining outcomes. He concludes that as the skill level of professional money managers has escaladed over time, the luck component becomes the more dominant factor. There are fewer and fewer Excess Return opportunities. Hence, expect that persistent superior performance should degrade even more in the future and should be more difficult to identify.
That’s an imperfect signal that favors an Index-like approach. Institutions have recognized that signal, and are moving more aggressively in that direction. Perhaps we should too?
Best Wishes.
