Unformatted text preview: tegy is as follows: whenever Warren Buffet publicly announces that he has purchased a stock, the fund will purchase the same stock based on the view that Warren Buffet is a very skilled investor who must be able to identify undervalued stocks based on superior information. Explain below how you expect the strategy to perform based on the following alternative assumptions? a) Assume that Warren Buffet is indeed highly skilled, and the market fully understands just how skilled he is.
