New academic
research has just been published that further
supports AlphaClone's research and investment approach.
The new paper which is entitled "Best Ideas" by Cohen, Polk and Silli concludes that fund managers'
high conviction and top holding stock ideas "outperform the market by
one to four percentage points a quarter depending on the benchmark used."
Below is the paper’s abstract.
The authors use different definitions for “Best Ideas” but all of them center around the relative proportion a manager allocates to an individual holding and all of them outperform including “popular” Best Ideas (similar to our “Popularity” strategy) and “fresh” Best Ideas (which AlphaClone just calls “Best Ideas”).
The approach taken above is nearly identical to cloning AlphaClone’s High
Concentration fund group – which dynamically selects the 25 funds that have the
highest market value spread across the smallest number of holdings (i.e. a high
relative portfolio allocation). We
highlighted this group a few weeks ago but its worth repeating that the group
does very well across all our clone strategies:

A couple of weeks ago, we highlighted the fact that being popular in the right circles was potentially very profitable when it comes to clone investing – this group’s Top 10 Popularity clone makes our point again very nicely. How’s that clone performing YTD? It’s beating the S&P500 Total Return Index by 23 percentage points. Yes, 23 percentage points. Here’s what it holds today:

ABSTRACT:
by
Cohen, Polk and Silli
We examine the performance of stocks that represent managers' "Best Ideas." We find that the stock that active managers display the most conviction towards ex-ante, outperforms the market, as well as the other stocks in those managers' portfolios, by approximately one to four percent per quarter depending on the benchmark employed. The results for managers' other high-conviction investments (e.g. top five stocks) are also strong. The other stocks managers hold do not exhibit significant outperformance. This leads us to two conclusions. First, the U.S. stock market does not appear to be efficiently priced, since even the typical active mutual fund manager is able to identify stocks that outperform by economically and statistically large amounts. Second, consistent with the view of Berk and Green (2004), the organization of the money management industry appears to make it optimal for managers to introduce stocks into their portfolio that are not.
