Evidence suggests the professional investors in my sample have significant stock-picking skills. Interestingly, these skilled investors share their profitable ideas with their competition. I test various private information exchange theories in the context of my data and determine that the investors in my sample share ideas to receive constructive feedback, gain access to a broader set of profitable ideas, and attract additional arbitragers to their asset market. The proprietary data I study are from a confidential website where a select group of fundamentals-based hedge fund managers privately share investment ideas. The investors I analyze 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 and special situation investments.
