| Tiivistelmä: | CAPM betas are generally estimated from historical data and applied to a future period. There is widespread evidence that the CAPM betas vary considerably over time and this raises two questions: can this variation be explained and can it be forecast better than the "five-year rule of thumb" (i.e. using the most recently estimated beta?). The authors estimate time-varying betas and explain the time-variation in the betas using regression models which are subsequently used for forecasting. |
