From the above link: I see I'm not the only one that finds Hussman's commentary to be of no practical value. If you want to be scared out of the market, read Chicken Little, er, Hussman. If you want to make money, read something else.
Certainly Hussman is persuasive. If you have no ability to think critically and idependantly then probably Hussman is not for you (though that is debatable because when the inevitable backend of the economic cycle arrives Hussman will beat most fund managers, will keep his clients money safe and ready to enter at the beginning of the start of the next economic cycle). For those who find his commentaries an education (as opposed to a market prediction) there is a lot of value to his writing.
