| Abstract: | Existing studies have concentrated on predicting stock market returns mainly in the U.S. market. We focus on the predictive power of the average correlation, an indicator of co-movements of returns on industry portfolios, and estimate a number of regression models using more than 10,000 monthly observations from 18 developed and 9 developing markets. We find that the average correlation is an effective predictor in most markets. This predictive power is not driven by the state of the economy. It is also not sensitive to subsample periods, although it is stronger in the most recent period and weaker during financial crises. |
