We use price pressure resulting from purchases by mutual funds with large capital inflows to identify overvalued equity. This is a relatively exogenous overvaluation indicator as it is associated with who is buying – buyers with excess liquidity – rather than what is being purchased. We document substantial stock price impact associated with purchases by high-inflow mutual funds, and find the probability of an SEO, insider sales, and the probability of a stock-based acquisition increase significantly in the four quarters following the mutual fund buying pressure. These results provide new evidence that firm managers are able to identify and exploit overvalued equity.
