Why risk comes first
Risk management is the discipline of protecting capital so you can stay in the game. It is the one skill that separates people who last from people who don't — and it matters far more than picking the “right” stock.
A simple truth of arithmetic: a 50% loss needs a 100% gain just to get back to even. Avoiding large losses is mathematically more powerful than chasing large gains.
Position sizing — the core skill
Position sizing answers “how much?” before “what?”. A common framework risks only a small, fixed percentage of capital on any single idea, and lets the distance to your stop decide the quantity.
Risk-based sizing: your max risk per trade decides the quantity, not your conviction.
Quantity = (Capital × Risk%) ÷ (Entry − Stop)
Risk-reward & expectancy
Before entering, compare what you risk to what you might gain. A favourable risk-reward means you can be right less than half the time and still come out ahead over many trades.
Compares the distance to your stop with the distance to your target.
Reward ÷ Risk = (Target − Entry) ÷ (Entry − Stop)
Expectancy ties it together: (win-rate × average win) − (loss-rate × average loss). A positive expectancy, repeated with disciplined sizing, is what an edge really means.
Diversification & drawdown
- Diversify across businesses, sectors and asset classes so no single event can ruin you.
- Cap concentration — a rough limit per position keeps one mistake from being fatal.
- Respect drawdown — the peak-to-trough fall in your capital; small, controlled drawdowns are survivable, deep ones are not.
- Never average down blindly on a losing leveraged position — that is how small losses become account-ending ones.

Test yourself
1. A 50% loss requires what gain to recover?
Losing half means you must double what's left to break even — why avoiding big losses matters.
2. Position size should be decided by…
Risk-based sizing uses capital-at-risk and stop distance, not conviction.
3. A favourable risk-reward lets you…
Good risk-reward means winners outweigh losers even with a sub-50% hit rate.
FAQs
Many disciplined traders risk only about 1–2% of their capital on any single idea, so that a string of losses can't do serious damage. The exact figure is personal, but the principle — small, fixed, pre-decided risk — is what matters. This is education, not advice.
No. Long-term investors manage risk through diversification, position limits, asset allocation and not over-concentrating in one stock. Everyone who puts capital at risk needs it.
They cap loss in normal conditions, but gaps and illiquid moves can cause execution beyond the level. They are a discipline that reduces risk, not an absolute guarantee.
No. Assured or guaranteed return schemes in the securities market are a serious red flag and are specifically warned against by SEBI and the exchanges. See the investor advisory in our footer and never transfer funds to unauthorised persons.
