I believe the very best money is made at the market turns. Everyone says you get killed trying to pick tops and bottoms and you make all your money by playing the trend in the middle. Well for twelve years I have been missing the meat in the middle but I have made a lot of money at tops and bottoms.

There's such an emphasis on making money that we've really taken the humanity out of business.

Fundamentals might be good for the first third or first 50 or 60 percent of a move, but the last third of a great bull market is typically a blow-off, whereas the mania runs wild and prices go parabolic... There is no training, classroom or otherwise, that can prepare for trading the last third of a move, whether it's the end of a bull market or the end of a bear market.

Where you want to be is always in control, never wishing, always trading, and always first and foremost protecting your ass. That's why most people lose money as individual investors or traders because they're not focusing on losing money. They need to focus on the money that they have at risk and how much capital is at risk in any single investment they have. If everyone spent 90 percent of their time on that, not 90 percent of the time on pie-in-the-sky ideas on how much money they're going to make, then they will be incredibly successful investors.

The concept of paying one-hundred-and-something times earnings for any company for me is just anathema. Having said that, at the end of the day, your job is to buy what goes up and to sell what goes down so really who gives a damn about PE's?

Don't be a hero. Don't have an ego. Always question yourself and your ability. Don't ever feel that you are very good. The second you do, you are dead.

I believe that great success is possible in any field — from music to mathematics to macro trading.
