For beginners, what matters most is not a complicated secret but long-proven principles. The five points below are common traits of investors who survived market cycles.
1) Never Lose Big
Warren Buffett style: “Rule No.1: Never lose money. Rule No.2: Never forget Rule No.1.”
It does not mean zero losses; it means preventing a single large loss from damaging your account.
2) Buy with a Margin of Safety
Following Benjamin Graham's philosophy, avoid overpaying relative to value and secure a margin of safety.
3) Stay Within Your Circle of Competence
Start with industries and businesses you truly understand to reduce judgment errors.
4) Be Patient, Not Hyperactive
Peter Lynch and Charlie Munger also emphasized focus and holding during high-quality opportunities over excessive trading.
5) Keep a Repeatable Process
When you document entry rules, stop rules, position sizing, and review routines, skill starts to dominate luck.
Quick Checklist
- Keep per-trade risk within 1??% of total capital
- Do not buy what you do not understand
- Buy favorable odds, not emotional excitement
- If you break your rules, record it as a failure even if it made money
