Rs 720 and Rs 730 Puts Draw Heavy Interest as HDFC Bank Ltd. Trades Near 52-Week Low

Put Options Event and Cash Market Context

On 26 August 2026, the most active put strikes for HDFC Bank Ltd. were Rs 720 and Rs 730, with 1,660 and 1,992 contracts traded respectively. The combined turnover for these strikes was approximately ₹320.66 lakhs. The underlying stock closed at Rs 727.95, hovering just above its 52-week low of Rs 715.10. Despite this proximity to the low, the stock underperformed its sector by 0.82% on the day and slipped 0.14% in the previous session, while the Sensex gained 0.14%. This muted price action contrasts with the surge in put contracts, suggesting a nuanced interpretation of the options activity — is this a sign of defensive positioning or a directional bearish stance?

Strike Price Analysis: Moneyness and Distance

The Rs 720 put strike lies approximately 1.1% out-of-the-money (OTM) relative to the current price, while the Rs 730 strike is about 0.3% in-the-money (ITM). Both strikes are close to the underlying price, indicating that the put activity is concentrated around near-the-money options. The expiry date of 29 September 2026 is roughly a month away, providing a moderate time horizon for these positions to play out.

Given the stock’s proximity to its 52-week low and the closeness of these strikes to the current price, the put activity could reflect a hedging strategy against further downside or a directional bearish bet anticipating a decline below these levels. However, the relatively small distance from the underlying price suggests that outright bearish speculation would require a near-term drop below Rs 720 or Rs 730, which has not yet materialised in the cash market — how does this strike proximity influence the likely intent?

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

Put options inherently carry ambiguous signals. Buying puts can be a bearish directional bet, but it can also serve as insurance for existing long positions. Conversely, selling puts (put writing) is a bullish strategy, where the seller collects premium betting the stock will not fall below the strike.

In this case, the Rs 720 and Rs 730 strikes’ near-the-money status combined with the stock’s recent sideways to slightly negative price action suggests a mixed picture. The stock’s underperformance and proximity to the 52-week low could motivate some investors to buy puts as protection against further declines. Yet, the lack of a sharp price drop and the stock’s position above the 5-day moving average imply that the rally is not decisively broken, which may encourage put sellers to collect premium, expecting the stock to hold above these levels.

Therefore, the put activity likely reflects a combination of protective hedging and put writing rather than purely bearish positioning. The sizeable open interest at these strikes supports this view, indicating established positions rather than purely speculative fresh bets.

Open Interest and Contracts Analysis

The Rs 730 put strike shows an open interest of 14,368 contracts, while the Rs 720 strike has 8,854 contracts open. The number of contracts traded on 26 August (1,992 and 1,660 respectively) represents a significant turnover relative to open interest, especially at Rs 720 where the ratio of traded contracts to open interest is approximately 0.19. This suggests fresh activity but also adjustments to existing positions.

The higher open interest at Rs 730 compared to Rs 720 indicates that the Rs 730 strike is a more popular level for hedging or put writing. The concentration of open interest near the current price points to a technical support zone where traders expect the stock to find footing or are protecting against a breach of this level.

Cash Market Context: Moving Averages and Delivery Volumes

HDFC Bank Ltd. currently trades above its 5-day moving average but remains below the 20-day, 50-day, 100-day, and 200-day moving averages. This positioning suggests short-term resilience amid longer-term weakness. The Rs 720 and Rs 730 put strikes roughly align with a support zone below the 50-day moving average, consistent with a technical hedge against a pullback to this level.

Delivery volumes on 25 August were 79.75 lakh shares, down 44.93% against the 5-day average, indicating falling investor participation despite the stock’s recent price stability. This thinning delivery-backed volume may explain why put buyers are seeking protection — does this divergence between price and delivery volumes signal caution?

Conclusion: Protective Hedging and Put Writing Dominate the Put Activity

The near-the-money Rs 720 and Rs 730 put strikes have attracted significant trading and open interest ahead of the 29 September expiry, while HDFC Bank Ltd. trades close to its 52-week low with subdued price movement. The data suggests that the put activity is less about outright bearish conviction and more about hedging existing long positions or put writing to collect premium, anticipating the stock will hold above these levels.

The stock’s position above the 5-day moving average and the alignment of put strikes with technical support zones reinforce this interpretation. However, the falling delivery volumes and underperformance relative to the sector indicate some caution among investors. This nuanced picture highlights the importance of connecting options data with cash market trends to understand the true market sentiment — should investors view this put activity as a signal to hedge or a sign of underlying weakness?
