The efficient market theory is one of the better models in the sense that it can be taken as true for every purpose I can think of. For investment purposes, there are very few investors that shouldn't behave as if markets are totally efficient.

The distribution of the market is fat-tailed relative to the normal distribution... For passive investors, none of this matters, beyond being aware that outlier returns are more common than would be expected if return distributions were normal.

Markets are efficient, but there are different dimensions of risk and those lead to different dimensions of expected returns. That's what people should be concerned with in their investment decisions and not with whether they can pick stocks, pick winners and losers among the various managers delivering basically the same product.

Active management is a zero-sum game before cost, and the winners have to win at the expense of the losers.

I can't figure out why anyone invests in active management, so asking me about hedge funds is just an extreme version of the same question. Since I think everything is appropriately priced, my advice would be to avoid high fees. So you can forget about hedge funds.

I don't even know what that means. People who get credit have to get it from somewhere. Does a credit bubble mean that people save too much during that period? I don't know what a credit bubble means. I don't even know what a bubble means. These words have become popular. I don't think they have any meaning.

In an efficient market at any point in time the actual price of a security will be a good estimate of its intrinsic value.

I’d compare stock pickers to astrologers but I don’t want to bad mouth astrologers.

An investor doesn’t have a prayer of picking a manager that can deliver true alpha.
