Rs 730 and Rs 740 Puts Draw Over 9,500 Contracts on HDFC Bank Ltd. Ahead of 28 July Expiry

Put Options Event and Cash Market Context

On 24 July 2026, the most active put contracts on HDFC Bank Ltd. were at the Rs 730 and Rs 740 strikes, with 4,736 and 4,831 contracts traded respectively. The combined turnover for these strikes was approximately ₹2.57 crores, reflecting significant market interest. Open interest stood at 3,936 for the Rs 730 puts and 5,226 for the Rs 740 puts, indicating a substantial build-up of positions ahead of expiry.

The underlying stock closed at Rs 739.35, just 1.86% above its 52-week low of Rs 726.65, and has been on a downward trajectory, losing 9.66% over the past five trading sessions. The stock is trading below all major moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — signalling a bearish technical setup. Delivery volumes have risen by 24.27% compared to the five-day average, suggesting increased investor participation despite the decline.

The juxtaposition of heavy put activity with a falling stock price invites a closer look at the nature of this options market behaviour — HDFC Bank Ltd. — is this put buying a bearish bet or a strategic hedge?

Strike Price Analysis: Moneyness and Intent

The Rs 740 strike is effectively at-the-money (ATM), just 0.9% above the current price, while the Rs 730 strike is slightly out-of-the-money (OTM) by about 1.3%. The proximity of these strikes to the underlying price is critical in interpreting the put activity. ATM puts typically reflect directional bearish bets or protective hedging, whereas OTM puts can be used for hedging or speculative purposes depending on market context.

Given the stock’s recent decline and proximity to the 52-week low, the Rs 730 and Rs 740 strikes sit near key support levels. The Rs 730 strike is close to the recent low of Rs 726.65, which may be viewed as a technical floor by traders. This suggests that put buyers could be positioning for further downside or protecting existing long positions against a deeper fall.

Alternatively, the significant open interest at these strikes could also indicate put writing, where sellers collect premium betting the stock will not breach these levels by expiry. However, the elevated turnover and fresh contracts traded relative to open interest suggest more fresh buying than writing activity.

The strike distance is the first clue about intent — are these puts signalling conviction in a further slide or a cautious hedge against volatility?

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

Put options inherently carry ambiguous signals. The three primary interpretations for heavy put activity are: directional bearish positioning (put buying), protective hedging of existing long stock holdings, or put writing as a bullish income strategy.

In this case, the stock’s five-day loss of nearly 10% and trading below all major moving averages support the possibility of directional bearish bets. The ATM Rs 740 puts, with the highest open interest and turnover, align with traders anticipating further weakness.

However, the Rs 730 puts, slightly OTM but close to a technical support zone, may also be used by long holders to hedge downside risk. The increased delivery volumes amid the decline suggest that some investors are still actively participating in the cash market, possibly prompting protective put purchases.

Put writing appears less likely given the fresh contracts traded (9,567 combined) exceed open interest (9,162), indicating new positions rather than premium collection on existing ones. If put writing were dominant, open interest would typically be higher relative to traded contracts.

Open Interest and Contracts Analysis

The ratio of contracts traded to open interest is approximately 1.02 for the Rs 730 puts and 0.92 for the Rs 740 puts, indicating a high level of fresh activity. This suggests that traders are actively establishing new positions rather than merely rolling over or closing existing ones.

Open interest concentration at the Rs 740 strike (5,226 contracts) is notably higher than at Rs 730 (3,936 contracts), which may reflect a preference for protection or bearish bets closer to the current price. The sizeable open interest at these strikes also implies that these levels are key reference points for market participants as expiry approaches.

Fresh positioning at these strikes, combined with the stock’s technical weakness, supports the interpretation of directional bearishness or hedging rather than put writing. The open interest data also suggests that the market is bracing for potential volatility around these levels.

Cash Market Context: Technical and Delivery Volume Insights

HDFC Bank Ltd. has been under pressure, trading below all major moving averages, which typically signals bearish momentum. The stock’s proximity to its 52-week low adds to the technical vulnerability. However, the rise in delivery volumes by 24.27% on 23 July indicates that investors are still actively transacting shares, which could reflect accumulation or repositioning rather than capitulation.

The combination of falling prices and rising delivery volumes often points to genuine market interest rather than purely speculative moves. This dynamic may explain why put buyers are active: they could be hedging long positions amid uncertainty rather than purely speculating on a crash.

The 28 July expiry is just days away, adding urgency to options positioning. The stock’s technical setup and delivery volume trends provide a nuanced backdrop to the put activity — should investors interpret this as a signal to hedge or a sign of deeper bearish conviction?

Conclusion: Most Likely Interpretation of Put Activity

The heavy put option activity at the Rs 730 and Rs 740 strikes on HDFC Bank Ltd. ahead of the 28 July expiry is best understood as a combination of directional bearish positioning and protective hedging. The stock’s recent decline, trading below all key moving averages, and proximity to its 52-week low support the bearish interpretation.

However, the elevated delivery volumes and fresh contracts traded suggest that some investors may be using puts to guard against further downside rather than purely speculating on a collapse. Put writing appears less prominent given the turnover and open interest patterns.

Ultimately, the options data and cash market context together indicate a cautious market stance, with participants bracing for potential volatility near critical support levels. does this mean investors should hedge their exposure or prepare for further downside in HDFC Bank Ltd.?
