Over 10 years of stock trading insights summarized: 1. Don’t go long at mid-to-high levels, don’t go short at low levels. 2. A pullback that doesn’t break a new low is a buying point; a rebound that doesn’t hit a new high is a selling point. 3. There’s only one true leader in the market; the rest are just runners-up. 4. Trading volume doesn’t lie—extreme volume signals an imminent trend reversal. 5. Don’t try to catch the bottom during continuous declines; there’s no bottom. 6. Interpret good news negatively, and treat bad news as positive. 7. Once a trend forms, it won’t change easily. 8. Rapid rises and slow declines signal selling; rapid declines and slow rises signal accumulation. 9. Trade new themes, not old ones—capital prefers fresh ideas. 10. After a big win, go empty-handed. Luck is limited, and opportunities come to those who wait.
