Abstract
We consider three sets of phenomena that feature prominently - and separately - in the financial economics literature: conditional mean dependence (or lack thereof) in asset returns, dependence (and hence forecastability) in asset return signs, and dependence (and hence forecastability) in asset return volatilities. We show that: Volatility dependence produces sign dependence, long as expected returns are nonzero; sign dependence is not likely to be found via traditional market timing tests; sign dependence is not likely to be found in very high-frequency or very low-frequency returns; sign dependence is very much present in monthly U.S. equity returns, and its properties match closely our theoretical predictions.
