As a whole, we find the performance of Taiwan equity funds managed by professional investor is not as good as the market except 2005. But foreign-invested equity funds have significantly small standard deviation (risk).

When bull market transforms to bear market, the performance of domestic equity funds are good significantly; though they are not good as bear market transforms to bull market.
