Rs 790 and Rs 800 Puts Draw Over 4,600 Contracts on HDFC Bank Ltd. Ahead of April Expiry

Put Options Event and Cash Market Context

On 13 Apr 2026, HDFC Bank Ltd. saw 2,335 put contracts traded at the Rs 790 strike and 2,358 contracts at Rs 800, both expiring on 28 Apr 2026. The turnover for these strikes was ₹235.53 lakhs and ₹297.12 lakhs respectively, indicating significant premium flow. The underlying stock price closed at Rs 789.85, marginally below the Rs 790 strike and about 1.3% below the Rs 800 strike. This proximity to the current price places the Rs 790 puts at-the-money (ATM) and the Rs 800 puts slightly in-the-money (ITM).

The stock underperformed its private sector banking peers, falling 2.39% on the day and opening with a gap down of 2.32%. Intraday lows touched Rs 787.50, reflecting a modest downward momentum. The sector itself declined by 2.01%, while the Sensex fell 1.76%, placing HDFC Bank Ltd. in line with broader market weakness rather than isolated pressure. HDFC Bank Ltd.’s delivery volume on 10 Apr was 2.13 crore shares, down 26.15% from its five-day average, suggesting a decline in investor participation during the recent pullback — does this reduced delivery volume hint at a lack of conviction behind the fall?

Strike Price Analysis: Moneyness and Intent

The Rs 790 strike sits almost exactly at the current market price, while the Rs 800 strike is about 1.3% above it, making the latter ITM. This positioning is critical in interpreting the put activity. ATM and ITM puts typically carry higher premiums and are more likely to be purchased for protection or directional bearish bets rather than speculative hedging far out-of-the-money (OTM).

Given the stock’s recent decline and proximity to these strikes, the put activity could reflect fresh bearish positioning anticipating further downside. Alternatively, the Rs 800 ITM puts might be part of a spread strategy or protective hedging for existing long positions, especially since the stock remains above its 5-day moving average but below longer-term averages such as the 20-day and 50-day. The Rs 790 strike roughly aligns with a short-term support zone, which could make these puts attractive for hedging against a pullback rather than outright directional bets — is this activity signalling caution or conviction?

Interpreting the Put Activity: Bearish, Hedging, or Put Writing?

Put options inherently carry ambiguous signals. The heavy volume at ATM and ITM strikes on a stock that is falling suggests a tilt towards bearish positioning or protective hedging rather than put writing, which typically involves OTM strikes and premium collection. The open interest (OI) at Rs 790 is 2,589 contracts, while at Rs 800 it is 5,550 contracts, indicating that the Rs 800 puts have a more established base of existing positions.

The ratio of contracts traded to open interest is approximately 0.9 for Rs 790 and 0.42 for Rs 800, suggesting that the Rs 790 activity is more fresh and aggressive, while Rs 800 sees more adjustment or rollovers. This pattern supports the view that recent put buying at Rs 790 is directional, possibly anticipating further weakness, whereas Rs 800 activity may be a mix of hedging and position management.

Open Interest and Contracts Analysis

The combined open interest of 8,139 contracts at Rs 790 and Rs 800 strikes is substantial, reflecting significant interest in downside protection or bearish bets. The fresh volume of 4,693 contracts traded on 13 Apr 2026 represents more than half the total OI, indicating active repositioning ahead of the 28 Apr expiry. This level of activity suggests that traders are either initiating new bearish positions or increasing hedges against existing long exposure.

Given the stock’s recent underperformance and the proximity of the strikes to the current price, the fresh put buying is unlikely to be put writing, which would typically involve selling OTM puts to collect premium. Instead, the data points to a combination of protective hedging and cautious bearish positioning, especially as the stock trades below its 20-day and 50-day moving averages, which often act as resistance in a downtrend.

Cash Market Context: Moving Averages and Delivery Volumes

HDFC Bank Ltd. currently trades above its 5-day moving average but remains below the 20-day, 50-day, 100-day, and 200-day moving averages. This mixed technical picture suggests short-term support but medium-term resistance, consistent with a stock in a corrective phase rather than a sustained rally or collapse.

The decline in delivery volumes by over 26% compared to the five-day average indicates that the recent price drop may lack strong conviction from long-term holders, which often prompts hedging activity among institutional investors. The put buying at ATM and ITM strikes aligns with this interpretation, as investors seek to protect gains or limit losses amid uncertain momentum — should investors view this as a prudent hedge or a warning sign?

Conclusion: Protective Hedging with a Bearish Undertone

The heavy put activity at Rs 790 and Rs 800 strikes on HDFC Bank Ltd. ahead of the 28 Apr expiry reflects a complex market stance. The proximity of these strikes to the current price, combined with the stock’s recent decline and subdued delivery volumes, suggests that the put buying is primarily protective hedging by investors wary of further downside. However, the fresh volume and open interest ratios also indicate a degree of bearish positioning, as some traders appear to be speculating on continued weakness.

Put writing seems less likely given the strike selection and premium turnover, reinforcing the interpretation that the options market is cautious rather than outright bullish. The mixed technical signals from moving averages further support a scenario of consolidation with downside risk rather than a clear trend reversal.
