Rs 750 and Rs 760 Puts Draw Over 6,000 Contracts on HDFC Bank Ltd. Ahead of 26 May Expiry

Put Options Event and Cash Market Context

On 21 May 2026, HDFC Bank Ltd. saw 3,140 contracts traded at the Rs 750 put strike and 3,355 contracts at the Rs 760 strike, both expiring on 26 May 2026. The total turnover for these puts was approximately ₹2 crore, with open interest standing at 7,079 and 4,466 contracts respectively. The underlying stock closed at Rs 766, just 4.95% above its 52-week low of Rs 726.65, and marginally up 0.61% on the day, in line with sector performance.

This concentrated put activity near expiry raises the question: is this a protective hedge against a short-term pullback, a directional bearish bet, or put writing signalling confidence in the stock’s near-term resilience?

Strike Price Analysis: Moneyness and Distance from Underlying

The Rs 750 strike is approximately 2.1% out-of-the-money (OTM) relative to the current price of Rs 766, while the Rs 760 strike is about 0.8% OTM. Both strikes are close to the money, with the Rs 760 put nearly at-the-money (ATM). The proximity of these strikes to the underlying price suggests that the put activity is not deeply speculative but rather focused on near-term price protection or income strategies.

Given the stock’s recent modest gains after two days of decline and its position above the 5-day moving average but below longer-term averages (20-day, 50-day, 100-day, and 200-day), these strikes align with a technical support zone. This positioning is consistent with investors seeking to hedge against a potential pullback to these moving averages rather than anticipating a sharp decline.

Interpreting the Put Activity: Multiple Angles

Put option activity can be ambiguous. The Rs 750 and Rs 760 puts could represent:

• Bearish positioning: Buyers expecting a decline below these strikes by expiry.
• Protective hedging: Long holders of the stock buying puts to guard against downside risk amid recent volatility.
• Put writing: Sellers collecting premium, confident the stock will stay above these levels, effectively a bullish stance.

Given the stock’s slight upward movement and the closeness of the strikes to the current price, the hedging interpretation is compelling. The put buyers may be protecting gains after the recent rally, especially since the stock remains near its 52-week low and below key longer-term moving averages. Conversely, the sizeable open interest and turnover could also indicate put writing, where sellers are comfortable with the stock holding above these strikes, collecting premium in a narrow trading range.

Which interpretation holds more weight depends on the interplay between fresh contracts and open interest changes, as well as the stock’s short-term momentum.

Open Interest and Contracts Analysis

The ratio of contracts traded to open interest is notable. For the Rs 750 strike, 3,140 contracts traded against an open interest of 7,079, while the Rs 760 strike saw 3,355 contracts traded versus 4,466 open interest. This suggests significant fresh activity, particularly at the Rs 760 strike where the turnover-to-OI ratio is approximately 0.75, indicating active repositioning or new hedging strategies.

Such fresh put buying near expiry often reflects short-term risk management rather than outright bearish conviction. The open interest levels also imply that these strikes have been focal points for traders over recent sessions, possibly as part of spread strategies or protective collars.

Cash Market Context: Momentum and Moving Averages

HDFC Bank Ltd. has gained 0.61% on the day, recovering after two consecutive days of decline. The stock trades above its 5-day moving average but remains below the 20-day, 50-day, 100-day, and 200-day averages, indicating a mixed technical picture. This positioning suggests the stock is in a consolidation phase rather than a clear uptrend or downtrend.

Delivery volumes have fallen by 21.85% compared to the 5-day average, signalling reduced investor participation in the rally. This thinning participation may be why put buyers are seeking protection, as the rally lacks strong conviction from delivery-backed buying. Does this divergence between price gains and delivery volumes hint at a fragile rally?

Delivery Volume and Liquidity Considerations

The delivery volume on 20 May was 1.56 crore shares, down 21.85% from the 5-day average, while the stock remains liquid enough to support trades worth approximately ₹54.55 crore based on 2% of the 5-day average traded value. This liquidity profile supports active options trading and suggests that the put activity is not constrained by market depth.

Lower delivery volumes amid a narrow trading range of Rs 6.25 may encourage investors to hedge with puts, as the rally lacks broad-based participation. This dynamic often leads to increased demand for downside protection, especially near expiry.

Conclusion: Protective Hedging Most Likely, But Put Writing Also Possible

The combined evidence points to the put activity at Rs 750 and Rs 760 strikes being primarily protective hedging by long holders of HDFC Bank Ltd. rather than outright bearish positioning. The stock’s modest gains, proximity of strikes to the current price, and reduced delivery volumes support this interpretation.

However, the significant open interest and turnover also leave room for put writing strategies, where sellers collect premium expecting the stock to hold above these levels. The absence of a sharp decline and the stock’s position above the 5-day moving average reinforce this possibility.

With puts active near the money and the stock in a technical consolidation, should investors consider hedging their positions or view this as a sign of underlying strength?
