Put Options Event and Cash Market Context
On 22 Jul 2026, HDFC Bank Ltd. witnessed significant put option activity ahead of the 28 Jul 2026 expiry. The Rs 750 strike put led the volume with 6,554 contracts traded, followed by Rs 740 puts with 3,929 contracts and Rs 760 puts with 3,553 contracts. The underlying stock closed at Rs 754, hovering just above the Rs 750 strike, making these puts effectively at-the-money (ATM) or slightly out-of-the-money (OTM).
The total turnover for these strikes was substantial, with Rs 292.67 lakhs for Rs 750 puts and Rs 271.13 lakhs for Rs 760 puts, indicating active participation. Open interest (OI) at Rs 750 stands at 6,256 contracts, suggesting that a sizeable portion of this activity represents fresh positioning or adjustments to existing positions.
The stock has been under pressure recently, falling 8.01% over the past three days and trading below all key moving averages including the 5-day, 20-day, 50-day, 100-day, and 200-day. Delivery volumes rose sharply by 62.34% on 21 Jul to 2.78 crore shares, signalling increased investor participation amid the decline. Is this surge in put activity a reflection of growing bearish conviction or a strategic hedge against further downside?
Strike Price Analysis: Moneyness and Intent
The Rs 750 put strike is just 0.53% below the current stock price of Rs 754, placing it effectively ATM. The Rs 740 and Rs 760 strikes are roughly 1.9% OTM and 0.8% OTM respectively. This proximity to the underlying price is critical in interpreting the put activity.
ATM puts tend to be favoured by traders expecting near-term downside or seeking protection against a decline. The Rs 750 strike’s dominance in volume and OI suggests that market participants are positioning for a potential pullback or are hedging existing long holdings. The Rs 740 puts, being slightly more OTM, could represent a more directional bearish bet or a layered hedge.
Conversely, the Rs 760 puts, which are OTM on the upside, may indicate put writing or selling activity, where traders collect premium expecting the stock not to fall below that level. However, the volume and OI at Rs 760 are lower than at Rs 750, implying less emphasis on bullish put writing.
Interpreting the Put Activity: Bearish, Hedging, or Put Writing?
Put option activity can signal multiple strategies. The heavy volume and OI at ATM strikes on a falling stock often point to bearish positioning, as traders seek downside exposure. Given HDFC Bank Ltd.’s recent 8% decline and trading below all major moving averages, this interpretation holds weight.
However, the elevated delivery volumes and the stock’s proximity to a 52-week low also suggest that some investors may be hedging long positions to protect gains or limit losses. The put activity at Rs 750 and Rs 740 could be part of a protective strategy rather than outright bearish speculation.
Put writing, which involves selling puts to collect premium, is less evident here given the concentration at ATM strikes and the stock’s downward momentum. Typically, put writing is more prevalent when the stock is stable or rising, and strikes are OTM. The Rs 760 puts show some activity but not enough to indicate a dominant bullish put writing trend.

Open Interest and Contracts Analysis
The ratio of contracts traded to open interest provides insight into whether the activity is fresh or part of existing positions. At Rs 750, 6,554 contracts traded against an OI of 6,256, indicating that much of this volume represents new positioning or significant adjustments. The Rs 740 strike shows 3,929 contracts traded versus 4,388 OI, also suggesting fresh activity.
Such high turnover relative to OI at ATM strikes on a declining stock typically signals active repositioning, either by traders increasing bearish exposure or by longs seeking protection. The Rs 760 strike’s lower turnover-to-OI ratio points to less aggressive activity there.
Does this fresh positioning confirm a shift in market sentiment or a tactical hedge?
Cash Market Context: Technical and Delivery Insights
HDFC Bank Ltd. is currently trading below all major moving averages, including the 5-day, 20-day, 50-day, 100-day, and 200-day, reflecting a bearish technical setup. The stock is also just 3.62% above its 52-week low of Rs 726.65, underscoring the recent weakness.
Delivery volumes have risen sharply by 62.34% on 21 Jul to 2.78 crore shares, indicating strong investor participation in the sell-off. This combination of technical weakness and rising delivery volumes supports the interpretation that the put activity is more than just protective hedging — it likely includes directional bearish bets.
However, the stock’s liquidity remains robust, with a trade size capacity of Rs 51.61 crore based on 2% of the 5-day average traded value, allowing for efficient execution of both hedging and speculative strategies.

Conclusion: A Blend of Protective Hedging and Bearish Positioning
The concentrated put option activity at Rs 750 and nearby strikes on HDFC Bank Ltd. amid a declining stock price and bearish technical setup suggests a dual narrative. While some of the put buying likely represents protective hedging by longs wary of further downside, the volume and open interest patterns also point to genuine bearish positioning by traders anticipating continued weakness.
Put writing appears less prominent given the strike proximity and market context, making it unlikely that the bulk of this activity is a bullish bet. The rising delivery volumes and the stock’s fall below all key moving averages reinforce the bearish undertone.
Options carry risk and are not suitable for all investors. Understanding the nuances of put activity alongside cash market trends is essential for informed decision-making.
