Trading Strategy Around Results

Important: Bank results are announced after market close (post 3:30 PM). The impact shows as a gap the next morning. This means you must hold positions overnight — which requires hedges.

Pre-Results (D-2): Buy Straddle

Buy an ATM straddle 2 days before HDFC/ICICI results. IV expands as traders hedge. Exit options: (a) sell the morning after results if you held overnight, or (b) sell the evening before results to capture only the IV expansion and avoid the gap risk.

Post-Results (D+1): Sell Premium

The morning after results, IV crushes as uncertainty resolves. Sell a short strangle at 9:25-9:35 AM and capture the crush. This works regardless of whether the results were good or bad — IV drops in both cases.

What to Watch in Bank Results

• Net Interest Margin (NIM): The spread between lending and deposit rates. Expanding NIM = bullish for bank stocks and BN.
• Gross NPA ratio: Asset quality. Falling NPAs = bullish, rising NPAs = very bearish (can trigger 300+ point BN fall).
• Loan growth: Year-over-year credit growth. Above 15% = bullish, below 10% = bearish.
• Provisions: Money set aside for bad loans. Higher provisions reduce profits and signal asset quality stress.
• Management guidance: Forward-looking statements on NIM, credit growth, and NPA outlook drive the post-results reaction more than the actual numbers.
