The paper presents an accounting framework for identifying characteristics that indicate expected returns. A model links expected returns to expected earnings and earnings growth, so a characteristic indicates expected returns if it indicates expected earnings and earnings growth that the market prices as being at risk. In applying the framework, the paper confirms book-to-price (B/P) as a valid characteristic in asset pricing: B/P is associated with higher expected earnings growth and also captures the risk of that growth not being realized. However, the framework also points to the forward earning-to-price (E/P) as a risk characteristic. Indeed, E/P, rather than B/P, is the relevant characteristic when there is no expected earnings growth, but the weight shifts to B/P with growth. The framework also enables the separation of the expected return for operating risk from that due to financing risk. With this separation, the paper revisits the puzzling negative relation that has been observed between leverage and realized returns, a finding that has been attributed to failure to control for operating risk. We find a positive relation between leverage and returns when operating risk characteristics identified by our model are recognized.
