帮你贴上NOTESBOOK1P58KEY concept的原话:
The three risk measures above give different perspectives and may give different rankings for portfolios. A portfolio with low diversification may have a higher Treynor measure, a higher alpha, but a lower Sharpe measure than another portfolio.
用了may 而不是most probably,那么此处指的大概不是一般情况。
BTW,KEY CONCEPT也看,果然仔细
