Trading is not about being right; it's about staying in the game. Master the fundamental rules of capital preservation and survival.
Most beginners enter the stock market thinking about how much money they can make. Professional traders enter the market thinking about how much they can afford to lose. Capital is a trader's "inventory" -- if you run out of it, you're out of business.
Risk management is the process of identifying, analyzing, and accepting or mitigating uncertainty in investment decisions. In simple terms: it's the art of ensuring that a few bad trades don't wipe out your entire account.
The most important mathematical rule in trading is to never risk more than 1% to 2% of your total trading capital on a single trade. This means if your account has Rs 1,00,000, your maximum loss on any one trade should not exceed Rs 2,000.
If you risk 10% per trade and lose 5 times in a row, you've lost 50% of your account. To get back to even, you now need to make a 100% return on your remaining capital!
If you risk 2% per trade, 5 losses only cost you 10%. You can recover from 10% easily; recovering from 50% is nearly impossible for most traders.
A stop loss is a pre-decided price at which you will automatically exit a losing trade. It is the most powerful tool for risk management. Never enter a trade without knowing exactly where your stop loss is.
Place your stop loss just below a major support level (for long trades) or above resistance (for short trades). This ensures you exit only when your trade thesis is proven wrong.
Using indicators like ATR (Average True Range) to place stop losses outside the "normal" daily noise of the stock.
The biggest mistake beginners make is "moving" their stop loss lower to avoid being stopped out. This converts a small, controlled loss into a large, uncontrolled one.
Position sizing is the calculation of how many shares to buy based on your risk. It is NOT about buying as many shares as your margin allows.
Example: You have Rs 1L capital. You risk 2% (Rs 2,000). You want to buy a stock at Rs 500 with a SL at Rs 480. Your SL distance is Rs 20.
Shares to buy = 2000 / 20 = 100 shares.
