This study simultaneously examines funds’ selectivity, beta stationary, and timing decisions by the modified method of Chen and Stockum (1986). We adopt GARCH, generalized least square (GLS), and a nonlinear parameter-estimator model to increase the estimate efficiency. The results indicate that up to 86% of the funds have stochastic betas, over 99% show positive but insignificant selectivity, and 83% indicate negatively significant market-timing ability. This suggests that Taiwan domestic-equity fund managers, on average, do not have stock selectivity and timing ability, which seems to support the efficient market hypothesis.
