Rs 780 Puts — 1.5% Above Current Price — Draw 3,484 Contracts on HDFC Bank Ltd.

Put Options Event and Cash Market Context

On 21 Jul 2026, HDFC Bank Ltd. saw significant put option activity ahead of the 28 Jul 2026 expiry. The Rs 780 strike put led with 3,484 contracts traded, generating a turnover of ₹3.82 crores. Other notable strikes included Rs 765 (4,474 contracts), Rs 750 (8,109 contracts), Rs 760 (3,972 contracts), and Rs 740 (3,536 contracts), cumulatively indicating a broad interest in downside protection or positioning.

The stock itself has been under pressure, falling 1.01% on the day and losing 6.08% over the past two sessions. It currently trades below all major moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — reflecting a sustained downtrend. Delivery volumes surged 200.42% on 20 Jul to 3.68 crore shares, suggesting rising investor participation amid the decline. Is this increased put activity a sign of fresh bearish bets or protective hedging?

Strike Price Analysis: Moneyness and Distance from Underlying

The Rs 780 put strike sits approximately 1.5% above the current stock price of Rs 768.45, making it an in-the-money (ITM) put option. Other strikes like Rs 765 and Rs 760 are also ITM or near-the-money, while Rs 750 and Rs 740 are out-of-the-money (OTM) puts, positioned 2.4% and 3.6% below the current price respectively.

ITM puts generally carry higher premiums and are often used either for directional bearish bets or as part of spread strategies. The presence of substantial contracts at ITM strikes suggests that some market participants may be positioning for further downside or protecting existing long holdings. Meanwhile, the sizeable volume at OTM strikes like Rs 750 and Rs 740 could indicate hedging against a sharper decline or put writing strategies.

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

Put option activity can be ambiguous. The ITM Rs 780 and Rs 765 strikes with high contract volumes may reflect bearish positioning, anticipating further price weakness. However, given the stock’s recent downtrend and trading below all key moving averages, this interpretation aligns with the technical picture.

Alternatively, the activity at OTM strikes such as Rs 750 and Rs 740, combined with the stock’s sharp fall and increased delivery volumes, could represent protective hedging by long investors seeking to limit losses amid volatility. The Rs 750 strike, with 8,109 contracts traded and an open interest of 5,931, suggests a significant fresh positioning that may be a hedge rather than outright bearish speculation.

Put writing, or selling puts to collect premium, is less likely here given the stock’s downward momentum and the predominance of ITM and near-the-money strikes. Put writers typically prefer stable or rising stocks to avoid assignment risk, which contrasts with the current market context for HDFC Bank Ltd.

Open Interest and Contracts Analysis

The Rs 780 put strike shows an open interest of 12,245 contracts, significantly higher than the 3,484 contracts traded on the day, indicating a large existing base of positions. The Rs 750 strike also has a substantial open interest of 5,931 against 8,109 contracts traded, suggesting fresh activity and possible new hedging or bearish bets.

The ratio of contracts traded to open interest varies across strikes, with the Rs 765 strike showing 4,474 contracts traded but only 1,741 open interest, implying mostly fresh positioning. This pattern supports the view that some traders are actively adjusting or initiating bearish or protective positions rather than merely rolling over existing ones.

Overall, the open interest data combined with contract volumes points to a mix of fresh bearish bets and hedging activity, rather than widespread put writing. How does this fresh positioning align with the stock’s technical and fundamental backdrop?

Cash Market Context: Technicals and Delivery Volumes

HDFC Bank Ltd. is currently trading below all major moving averages, including the 5-day, 20-day, 50-day, 100-day, and 200-day, signalling a bearish technical setup. The stock’s recent two-day decline of 6.08% and underperformance relative to its sector (-0.86% today) reinforce this downtrend.

Interestingly, delivery volumes surged by over 200% on 20 Jul to 3.68 crore shares, indicating strong investor participation despite the fall. This heightened delivery volume suggests that the decline is accompanied by genuine selling interest rather than mere speculative trading, which may explain the increased demand for put protection.

The Rs 780 put strike roughly corresponds to a resistance zone just above the current price, while the Rs 750 strike aligns with a potential support area below the 50-day moving average. This technical alignment supports the interpretation that put buyers are either positioning for further downside or hedging against volatility around these key levels.

Conclusion: Protective Hedging and Bearish Positioning Both Evident

The heavy put option activity in HDFC Bank Ltd. ahead of the 28 Jul expiry reflects a blend of market intentions. The predominance of ITM and near-the-money strikes with high open interest and fresh contracts suggests that bearish positioning is a significant factor, consistent with the stock’s technical weakness and recent price decline.

Simultaneously, the sizeable volume at OTM strikes and the alignment of put strikes with key technical support and resistance levels indicate that protective hedging is also at play. Investors holding long positions may be seeking to limit downside risk amid heightened volatility and delivery-backed selling pressure.

Put writing appears less likely given the current downtrend and elevated put premiums, but cannot be entirely ruled out at the lower strikes. The options market thus presents a nuanced picture, where both defensive and directional strategies coexist.

With puts active and calls also showing interest, should investors consider hedging their exposure or reassessing their stance on HDFC Bank Ltd.?
