语录：走势无法预知

"There are two kinds of investors, be they large or small: those who don't know where the market is headed, and those who don't know that they don't know.

Then again, there is a third type of investor - the investment professional, who indeed knows that he or she doesn't know, but whose livelihood depends upon appearing to know."
— William Bernstein, 2001


　　无论投资者拥有多少资金，都可以分为两种投资者：一种是不知道市场走势的人，另一种是虽然不知道但却以为他们自己知道的人。

另外，事实上还存在着第三种类型的投资者——投资专业人士，他们很清楚自己对市场走势一无所知，但他们却要不懂装懂地来维持生计。
