5 Landmines for Beginners
Landmine 1: Investing with Borrowed Money
Why it is dangerous:
- Investing with borrowed money carries extremely high risk; losses are magnified and must be repaid with pressure
- Interest costs eat into your returns
- May force you to sell at unfavorable times to repay debt
How to avoid: Only invest with disposable money, never borrowed funds. The money you invest should be an amount that "would not affect your life even if you lost it all."
Landmine 2: Buying on Tips
Why it is dangerous:
- Buying because someone told you a stock is good means you do not know when to sell
- By the time a tip reaches retail investors, it is often stale information
- When you buy, the person who gave the tip may be selling
How to avoid: Build your own analysis system. Learn basic technical and fundamental analysis, or check our Strategy Center for systematic trading methods to replace tip-based trading.
Landmine 3: Going All-In on a Single Stock
Why it is dangerous:
- If one stock drops 50%, your capital is halved
- Even if you are highly confident, unexpected events can happen (e.g., Lehman Brothers collapse in 2008)
How to avoid: Diversify across at least 5-10 stocks from different sectors. Refer to Diversification Guide.
Landmine 4: No Stop-Loss
Why it is dangerous:
- Small losses become medium losses, medium losses become large losses
- A 10% loss requires an 11% gain to break even; a 50% loss requires a 100% gain
How to avoid: Set a stop-loss for every trade. Beginners can use a fixed percentage method (5-8%). Refer to Three Principles of Stop-Loss Setting.
Landmine 5: Overtrading
Why it is dangerous:
- Commissions and taxes eat into your profits
- More decisions = more opportunities for mistakes
- Studies show that the most frequent traders among retail investors have the lowest returns
How to avoid: Reduce trade frequency; 3-5 trades per month is sufficient. Focus on quality trades, not quantity.
Summary
The common thread among these 5 landmines:
- Borrowing -- risk doubled
- Trading on tips -- no independent judgment
- All-in -- one mistake wipes out everything
- No stop-loss -- small losses become big losses
- Overtrading -- fees eat profits
