10 common option mistakes

These ten patterns destroy more retail options capital than all other errors combined. Each one feels reasonable in the moment, which is exactly why they keep working.

1. Buying far OTM options for 'cheap' lottery tickets

90%+ probability of expiring worthless. Expected value is deeply negative.

2. Ignoring IV before buying

Buying options when IV is already at 52-week highs guarantees expensive entry. Check India VIX and IV percentile first.

3. No stop-loss

Holding an option down 70% hoping it reverses. By then it's 95% down. Cut at 30–50% loss. The premium you save can fund better trades.

4. Letting profitable trades turn to losses

Your ₹100 option reaches ₹300. You hold for ₹500. It returns to ₹80. Book partial profits as the option becomes profitable.

5. Buying options right before major events

IV spikes before events. Immediately after, IV crashes. Unless your directional move is enormous, IV crush destroys the gains.

6. Selling naked options without a hedge

One black swan event wipes out months of premium. Always cap maximum loss with a debit spread.

7. Over-sizing positions

Risking 30–50% of capital on a single option position. Size for maximum loss tolerance, not potential gain.

8. Trading illiquid options

Wide bid-ask spreads on illiquid stock options cost 5–10% just to enter and exit. That is a hurdle your strategy has to clear before it earns anything, and it's why liquidity, index options and the most heavily traded stock options, is itself a cost decision rather than a preference.

9. Ignoring theta on long option positions

Buying an option and 'waiting' for the move. Every day without a move costs you. Buy options only when you expect a move SOON.

10. Confusing option P&L with underlying P&L

Just because Nifty moved up doesn't mean your call went up proportionally. Delta, theta, vega all interact. Calculate your expected P&L from Greeks before entering.
