The aggregate dividend payout ratio forecasts excess returns on both s
tocks and corporate bonds in postwar U.S. data. High dividends forecas
t high returns. High earnings forecast low returns. The correlation of
earnings with business conditions gives them predictive power for ret
urns; they contain information about future returns that is not captur
ed by other variables. Dividends and earnings contribute substantial e
xplanatory power at short horizons. For forecasting long-horizon retur
ns, however, only (scaled) stock prices matter. Forecasts of low long-
horizon stock returns in the mid-1990s are caused not by earnings or d
ividends, but by high stock prices.
