Reversion to the mean is the iron rule of the financial markets.

Our capitalistic scheme in the latter years of the 20th century seems to have lost its way. We've had a "pathalogical change" from traditional owners capitalism where most of the rewards have gone to those who make the investments and assume the risks to a new and deeply flawed system of managers capitalism where the managers of our corporations our investment system, and our mutual funds are simply take too large a share of the returns generated by our corporations and mutual funds leaving the last line investors - pension beneficiaries and mutual fund owners at the bottom of the food chain.

Sure there are some companies at the margins of our society that probably do that and I think we all have the responsibility as consumers and as investors to avoid them like the plague. If we do, they won't last very long. Doing what's right is the only possible formula for long-term - I emphasize long term - business success.

I would always advise young people to follow their star - not my star. They have to live their own life. If they decide they want to go into the investment business, do it, but make it a better business than it is today.

Corporate leaders surely have their problems, I believe that most CEOs are doing their best to hew to the ethical line. The problem is that that line has gotten blurred and that our moral standard seems to be "if everybody else is doing it, it's okay". That's not good enough for me.

But whatever the consensus on the EMH, I know of no serious academic, professional money manager, trained security analyst, or intelligent individual investor who would disagree with the thrust of EMH: The stock market itself is a demanding taskmaster. It sets a high hurdle that few investors can leap.

The historical data support one conclusion with unusual force: To invest with success, you must be a long-term investor.
