Trading style and beliefs[edit]
As reported in Market Wizards and the press, Jones futures trading style and beliefs are summarized as follows:
- Contrarian attempt to buy and sell turning points. Keeps trying the single trade idea until he changes his mind, fundamentally. Otherwise, he keeps cutting his position size down. Then he trades the smallest amount when his trading is at its worst.
- Considers himself as a premier market opportunist. When he develops an idea, he pursues it from a very-low-risk standpoint until he has been proven wrong repeatedly, or until he changes his viewpoint.
- Swing trader, the best money is made at the market turns. Has missed a lot of meat in the middle, but catches a lot of tops and bottoms.
- Spends his day making himself happy and relaxed. Gets out if a losing position is making him uncomfortable. Nothing’s better than a fresh start. Key is to play great defense, not great offense.
- Never average losers. Decreases his trading size when he is doing poorly, increase when he is trading well.
- He has mental stops. If it hits that number, he is out no matter what. He uses not only price stops, but time stops.
- Monitors the whole portfolio equity (risk) in realtime.
- He believes prices move first and fundamentals come second.
- He doesn’t care about mistakes made 3 seconds ago, but what he is going to do from the next moment on.
- 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.
