Bodnaruk and Ostberg (2009) introduced a simple formula for applying Merton’s (1987) incomplete-information adjustment to a stock’s required rate of return. The adjustment, which is based on market capitalization, idiosyncratic risk, and extent of investor ownership, should in principle improve discount rate estimates used in valuation. This article helps bridge the gap between theory and practice by explaining the application of the adjustment formula and providing adjustment estimates for some example U.S. stocks. The adjustment estimates tend to be material for volatile stocks with a relatively low percentage of shares held by institutional funds.
