學(xué)員你好，
M^2 focuses on total volatility as a measure of risk, but its risk adjustment leads to an easy-to-interpret differential return relative to the benchmark index.
這是說M^2這個指標用來衡量波動率，但是更加容易理解（如果投資組合的總風險和市場組合一樣，那么會額外產(chǎn)生的回報）。
The return for the perfect timer in each year is the average of the return on stocks and the return on bills. 完美的擇時指的是最終的收益是股票和債券收益的平均數(shù)，這個不對，應(yīng)該是熟大值。
Market timing involves shifting funds between a market-index portfolio and a safe asset, depending on whether the market index is expected to outperform the safe asset.
這個說法就正確了，完全是擇時的定義。
Managers can manipulate their performance measures by adjusting their risk-return profile in response to performance in the early part of an evaluation period.
可以操作的，如果投資完成之后再修改基準，然后找一個差的基準的話就可以使得投資的表現(xiàn)更好一些。
