News sentiment and stock return: Evidence from managers' news coverages

In this paper, we construct a monthly news-based manager sentiment (S-M) based on the tone of managers' news reports. Statistically, S-M has excellent predictability for the subsequent month's return in both in- and out-of-sample periods. we find that S-M contains additional information to forecast stock returns compared to popular economic predictors. After analysing the prediction performance at different sentiment levels, it is found that the prediction power of S-M is far better in the high sentiment period than in the low sentiment period. In terms of investing, S-M also generates considerable economic value for investors who use forecasting information to optimise their stock portfolios.
