The #1 Rule: Never Risk More Than 1-2%
This is the golden rule of risk management. On any single trade, never risk more than 1-2% of your total portfolio. If you've ever wondered how much of your portfolio to risk per trade, this is the answer that keeps professional traders in the game for decades.
The 1% Rule in Action
Portfolio size: ₹10,00,000
1% risk: ₹10,000 per trade
What this means:
- • If you buy a stock at ₹100 with stop-loss at ₹95 (5% risk)
- • You can buy ₹2,00,000 worth (₹10,000 ÷ 5% = ₹2,00,000)
- • If stopped out, you lose only 1% of portfolio
- • You can survive 100 consecutive losses before going broke
Position Sizing Formula
Calculate Your Position Size
Formula:
Position Size = (Portfolio × Risk%) ÷ (Entry Price - Stop Loss Price)
Example:
- • Portfolio: ₹10,00,000
- • Risk: 1% = ₹10,000
- • Entry: ₹200
- • Stop Loss: ₹190 (5% below entry)
- • Position Size: ₹10,000 ÷ (₹200 - ₹190) = ₹10,000 ÷ ₹10 = 1,000 shares
- • Total investment: ₹2,00,000 (20% of portfolio)
Stop-Loss Orders: Your Safety Net
A stop-loss order automatically sells your position if price drops to a certain level. It's your insurance policy against catastrophic losses. Learning how to use a stop-loss order to protect your investments is one of the simplest, highest-impact habits a new investor can build.
✓ When to Use Stop-Loss
- • Individual stock positions
- • Swing trades (days to weeks)
- • Volatile stocks
- • When you can't monitor daily
⚠ When to Skip Stop-Loss
- • Long-term holds (10+ years)
- • Index funds
- • DCA positions
- • Very low volatility stocks
Where to Set Your Stop-Loss
| Strategy | Stop-Loss Level | Best For |
|---|---|---|
| Tight | 2-5% below entry | Day trading, low volatility |
| Moderate | 5-10% below entry | Swing trading (recommended) |
| Wide | 10-20% below entry | Position trading, high volatility |
| Technical | Below support level | Chart-based traders |
Diversification: Don't Put All Eggs in One Basket
Even with perfect position sizing and stop-losses, you need diversification. Spread your risk across multiple positions.

Risk Management Saves Your Portfolio
Educational ExampleTwo traders, same picks, different risk management
Trader A: No Risk Management
- • Portfolio: ₹10,00,000
- • Buys ₹5,00,000 of one stock (50%)
- • No stop-loss
- • Stock drops 40%
- • Loss: ₹2,00,000 (20% of portfolio)
- • Needs 25% gain to recover
Trader B: Proper Risk Management
- • Portfolio: ₹10,00,000
- • Buys ₹1,00,000 of same stock (10%)
- • Stop-loss at 10% below entry
- • Stopped out at 10% loss
- • Loss: ₹10,000 (1% of portfolio)
- • Needs 1% gain to recover
The Difference
Same stock, same loss. Trader A lost 20% of portfolio and needs months to recover. Trader B lost 1% and can recover in days. Risk management is the difference between survival and ruin.

What Is the Difference Between Risk Management and Money Management?
People often use these terms interchangeably, but they answer different questions. Risk management decides how much you can afford to lose on each trade—the 1-2% rule, your stop-loss placement, and your maximum drawdown limits. Money management decides how your capital is allocated across positions—position sizing, diversification, and how much cash you keep in reserve. Beginners often want a single rule for how to protect your money in a stock market crash, but durable protection comes from combining both: small per-trade risk and a well-spread portfolio. Get these two working together and you remove most of the ways an account can blow up.
