We present evidence from an event study that runs counter to the notion that the momentum and book-to-market (B/M) effects can be fully explained by time-varying risk premia. We minimize the joint hypothesis problem in market-efficiency tests by examining a relatively short (26-day) window that...

We hypothesize that weather's emotional effects depend on climate and season, and examine the relation between weather (sunshine, wind, rain, snow, and temperature) and index returns separately for each region (cold, hot, and mild countries) and month. We find strong effects of all five weather...
