Do Hedge Fund Managers Have Stock Picking Skills?
Via SSRN (paper by Wesley R Gray):
I study novel data from a confidential website where a select group of fundamentals-based hedge fund managers privately share investment ideas. These value investors are not easily defined: they exploit traditional tangible asset valuation discrepancies such as buying high book-to-market stocks, but spend more time analyzing intrinsic value, growth measures, and special situation investments. Evidence suggests that the managers’ long recommendations earn economic and statistically significant long-term abnormal returns. Oddly enough, these managers share their profitable ideas with other skilled investors. This evidence is puzzling in a world where there is an efficient market for fund managers and asset prices.
