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.

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

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.

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.

People would be a lot more skeptical if they understood that there is an incredible amount of chance in the results that you observe for active managers. So the distribution of outcomes is enormously wide - but that's exactly what you'd expect by chance with lots of active managers who hold imperfectly diversified portfolios. The really good portfolios contain a lot of really lucky picks, and the really bad portfolios contain a lot of really unlucky picks as well as some really bad ones.

I don't think the Federal Reserve has any role in how high rates are right now. I don't understand why everyone is paying attention to this tapering. The Fed is using one kind of bond to buy another kind of bond. What's the big deal, and why is anyone taking the Fed seriously?
