Does Volatility Improve UK Earnings Forecasts?
We investigate the relation between UK accounting earnings volatility and the level of future earnings using a unique sample comprising some 10,480 firm-year observations for 1,481 non-financial firms over the 1985-2003 period. The findings confirm the in-sample result of an inverse volatility-earnings relation only for the 1998-2003 sub-period and for the most profitable firms. The out-of-sample forecast accuracy for the top earnings quintile improves when volatility is added as a regressor to a model including only lagged earnings. The findings are consistent with the over-investment hypothesis and the view that the earnings of the most volatile firms tend to mean revert more rapidly.
