Two-time U.S. Investment Champion Mark's Investment Insights: 1. One Foundation: Never Lose More Than 8% (Cut Loss) After establishing this discipline, he achieved an average annual return of 220% over 5 years. He never broke this rule in 28 years. All trades use hard stop-loss orders, including short selling. 2. Three Wealth Rules: Never buy at the bottom (right-side trading) Never sell too early (Let profits fly) Never hold, and never add to, losing stocks. 3. He Was Wrong More Than Right (Odds > Win Rate) With a win rate consistently below 50%, he still built a nine-figure fortune. Investing is not about prediction, but about odds and discipline. 4. Bell Curve Thinking For every trade, ask only one question: If I made this trade 1000 times, would I make a profit? Only act when the upside potential is at least 2 to 3 times the stop-loss. 5. Buy breakouts, not cheap. Buy leading stocks breaking out from a solid bottom pivot point. The goal is the right price, not the lowest. Add to your position only within the bottom pattern, when it breaks through a new pivot point. If the best pattern still doesn't present an opportunity, hold cash; never downgrade to buying inferior stocks. (Right side) 6. Turning profits into losses is the number one sin in trading. After making a profit, move your stop-loss to break-even, using part of your profit-taking to hold the remaining position for free. Never hold a position overnight without a profit cushion before earnings reports. 7. Position size is earned by the market, not determined by yourself. Don't attack without volume follow-through. If distribution is accumulating and its breadth is deteriorating, tighten your stop-loss and reduce your position size. Stop-loss is more reliable than emotions. 8. The hardest thing isn't technique, it's ego. Going to a casino is for excitement, but the market requires discipline. Don't overcomplicate trading.
