Rs 770 and Rs 780 Puts Draw Heavy Interest on HDFC Bank Ltd. as Stock Trades Below Key Moving Averages

Put Options Event and Cash Market Context

On 24 Apr 2026, the put options at the Rs 770 and Rs 780 strikes for HDFC Bank Ltd. were among the most actively traded contracts. The Rs 770 puts saw 4,659 contracts traded with an open interest of 3,696, while the Rs 780 puts recorded 4,874 contracts traded and an open interest of 3,050. The underlying stock price stood at Rs 778.0, placing the Rs 770 strike approximately 1.0% out-of-the-money (OTM) and the Rs 780 strike roughly at-the-money (ATM).

This concentrated activity ahead of the 28 Apr 2026 expiry coincides with a stock that has been losing ground for three consecutive sessions, falling 4.03% in that period. The stock is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a bearish technical setup. Delivery volumes have also declined by 6.03% against the five-day average, suggesting reduced investor participation in the cash market during this downtrend — does this diminished delivery volume explain the surge in put activity as a form of protection?

Strike Price Analysis: Moneyness and Intent

The Rs 780 strike sits almost exactly at the current underlying price, while the Rs 770 strike is slightly OTM by about 1.0%. This proximity to the current price is critical in interpreting the put activity. ATM puts are often used for directional bearish bets, as they provide immediate downside protection or profit if the stock declines. The Rs 770 puts, being marginally OTM, could serve as a hedge against a moderate pullback or as part of a spread strategy.

Given the stock's recent weakness and position below all major moving averages, the put strikes suggest that market participants are positioning for further downside or protecting existing long positions from near-term losses. However, the relatively small distance between the strikes and the underlying price also leaves room for alternative interpretations such as put writing, where sellers collect premium expecting the stock to hold above these levels — is this put activity signalling conviction in a support zone or a cautious bearish stance?

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

Put option activity can be ambiguous, especially when the stock is in a downtrend but the strikes are close to the current price. The Rs 780 ATM puts likely reflect some degree of bearish positioning, as buyers seek protection or profit from further declines. The Rs 770 OTM puts, however, could be a mix of fresh hedging by longs and put writing by sellers confident the stock will not breach this level before expiry.

The turnover figures reinforce this dual interpretation: Rs 191.4 lakhs for the Rs 780 puts and Rs 92.5 lakhs for the Rs 770 puts indicate significant premium flow, which could be split between buyers and sellers. The open interest levels, while substantial, are lower than the traded contracts, suggesting a large portion of this activity is fresh rather than rollovers or adjustments.

Open Interest and Contracts Analysis

The ratio of contracts traded to open interest is approximately 1.26 for the Rs 770 puts and 1.60 for the Rs 780 puts, indicating that a significant portion of the activity is fresh. This suggests new positioning rather than mere adjustments of existing positions. Fresh put buying at ATM and slightly OTM strikes in a falling stock typically signals a bearish stance or protective hedging by longs.

However, the open interest is still sizeable, which means some positions are being held into expiry, possibly reflecting a mix of strategies including put writing. The presence of both strikes with high turnover and open interest points to a nuanced market view rather than a one-sided directional bet.

Cash Market Context: Technicals and Delivery Volumes

HDFC Bank Ltd. is trading below all major moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — which is a bearish technical signal. The stock’s recent 4.03% decline over three days aligns with the increased put activity, supporting the interpretation of bearish positioning or hedging against further downside.

Delivery volumes have fallen by 6.03% compared to the five-day average, indicating weaker investor participation in the cash market during this decline. This thinning of delivery-backed trading may be prompting longs to seek protection through puts, as the rally or support lacks conviction — should investors consider this a warning sign or a temporary pullback?

Delivery Volume and Market Liquidity

The delivery volume on 23 Apr was 2.28 crore shares, down 6.03% from the recent average, while liquidity remains sufficient for sizeable trades with a 2% average traded value of Rs 66.96 crore. This suggests that while the stock remains liquid, the reduced delivery participation during the decline may be a factor behind the surge in put buying as a protective measure.

Conclusion: Protective Hedging with a Bearish Undertone

The heavy put activity at the Rs 770 and Rs 780 strikes on HDFC Bank Ltd. amid a declining stock price and weak technicals suggests a blend of protective hedging and bearish positioning. The proximity of the strikes to the current price and the fresh nature of the contracts traded indicate that market participants are either seeking downside protection or positioning for further weakness.

While put writing cannot be ruled out entirely, the overall context of falling prices, declining delivery volumes, and open interest patterns point more strongly towards cautious bearishness or risk management by longs. This nuanced picture highlights the importance of connecting options data with cash market trends to understand the true market sentiment — should investors be hedging their exposure or preparing for a deeper correction?
