Risk management basics
Beating the market is hard; staying in the market long enough to compound is mostly about not blowing up. That's what risk management is.
Risk capacity vs risk tolerance
Two different things, often confused:
- Risk capacity — how much loss you can financially absorb without derailing life goals. A function of income stability, time horizon, dependants, and emergency reserves.
- Risk tolerance — how much loss you can psychologically absorb without panic-selling.
Honest investors size positions to the lower of the two. The market will eventually test both numbers — it's much better to discover them on paper than in the middle of a 40% drawdown.
Diversification — the only "free lunch"
Holding a single stock concentrates idiosyncratic risk: one bad event (fraud, regulatory shock, lost contract) can wipe out the position. Holding 20 unrelated stocks spreads that risk so no single failure can ruin the portfolio. Diversification doesn't help you avoid market risk — when the whole market falls, everything falls together — but it removes the avoidable kind.
Practical caveats: 20 names from the same sector (say, all banks) are not diversified. Real diversification considers sector, factor (growth vs value), market cap, and geography.
Position sizing
A simple, conservative rule used by many serious investors: no single position should be able to lose more than 1–2% of your total portfolio if it goes against you. That number — call it your "risk per trade" — sets your position size.
Worked example: if your portfolio is ₹10,00,000 and your maximum acceptable loss on one position is 1% (₹10,000), and you're prepared to exit a stock if it drops 20% from your entry, then your position size is ₹10,000 ÷ 20% = ₹50,000. That's 5% of the portfolio.
Drawdowns
A drawdown is the peak-to-trough fall in a portfolio's value. They're inevitable. Indian equity markets have had drawdowns of 50%+ (2008, 2020). What kills returns is not the drawdown itself — it's selling at the bottom because you sized yourself for paper gains, not for the actual ride.
A useful exercise: cut your current portfolio value in half on paper. Does that number still let you sleep? If not, you're carrying more risk than you've admitted.
Asset allocation
Most of long-term return variation comes not from which stocks you pick, but from how much of your money is in equity vs everything else. A simple rule-of-thumb starting point: equity allocation = 100 − your age (in percent). At 30, that's 70% equity, 30% debt/cash; at 60, it's 40/60. Adjust up or down for your specific situation, but use it as a sanity anchor.
Don't confuse leverage with skill
Margin trading and F&O let you take positions much larger than your cash. Leverage amplifies both wins and losses. A 5x-leveraged position needs a 20% adverse move to wipe out your capital — and Indian small/mid caps routinely move 20% in a week. Many traders confuse the dopamine of leveraged wins with skill; the math eventually finds them.
An emergency fund comes first
Before any equity investing, keep 6–12 months of essential expenses in a liquid, low-risk place (savings account, liquid fund, FD). This is what stops you from selling stocks at the worst time to pay for an emergency.
