刚看到1976的这个帖子，总结的很全面

理论上讲，这些指标是可以作为分析一个基金好坏的技术指标，但是实际上也不能完全依赖的，要看环境决定用什么指标

For example, if 2 funds were being evaluated as components of a larger portfolio (in which unsystematic risk could be diversified away), then the fund with higher T ratio shoule be judged to the best performer.However, if we were choosing b/w the 2 managers (one of whom will manage the entire portfolio),then the total variability of assets under management is a concern and we would wish to choose the fund with higher S ratio.
