Risk Management for Investors
Risk management separates long-term successful investors from those who blow up their portfolios. The most skilled stock pickers in the world still lose money on individual trades — the difference is they lose small and win big.
Stop-Loss is a predetermined price at which you exit a losing position to prevent further damage. For long-term investors, a stop-loss might be a 20-25% decline in a stock (time-based, not price-based — reassess if the business fundamentals have changed). For traders, stop-losses are much tighter — typically 2-5% below entry. Set your stop-loss before entering the trade, not after.
Position Sizing is deciding how much capital to allocate to a single stock or trade. The 2% rule: never risk more than 2% of your total portfolio on a single trade. If you have Rs 5 lakh and your stop-loss is 10% below entry, buy only Rs 1 lakh of that stock (2% of Rs 5 lakh = Rs 10,000 max loss; Rs 1 lakh × 10% = Rs 10,000).
Risk-Reward Ratio compares potential profit to potential loss. A 3:1 ratio means you target Rs 3 profit for every Rs 1 risked. Even with a 40% win rate, a consistent 3:1 risk-reward strategy is profitable. Avoid trades where potential gain is less than 2x potential loss.
Maximum Drawdown is the largest peak-to-trough decline in your portfolio. If your portfolio went from Rs 10 lakh to Rs 6 lakh, that is a 40% drawdown. Psychologically, large drawdowns cause panic selling at exactly the wrong time. Design your portfolio to have a maximum acceptable drawdown before building it.
Behavioural Risks are often larger than market risks: overconfidence after a winning streak, panic selling during corrections, FOMO (Fear of Missing Out) chasing hot stocks, and averaging down in a falling stock without fundamental justification. Keep a trading journal to identify your personal behavioural biases.
