Rs 680 to 730 Puts Draw Over 15,000 Contracts on HDFC Bank Ltd. Ahead of September Expiry

Put Options Event and Cash Market Context

On 27 August 2026, HDFC Bank Ltd. saw significant put option activity ahead of the 29 September expiry. The most active strikes were Rs 680, Rs 700, Rs 710, Rs 720, and Rs 730, with contracts traded ranging from 2,526 at Rs 680 to 4,322 at Rs 720. Total turnover for these strikes exceeded ₹1,181 crores, signalling substantial interest in downside protection or positioning.

The stock closed at Rs 721.25, down 0.91% on the day, and has been underperforming its sector with a three-day consecutive decline of 1.36%. It trades just 0.55% above its 52-week low of Rs 715.1, and remains below all major moving averages including the 5-day, 20-day, 50-day, 100-day, and 200-day. Delivery volumes rose 6.44% against the five-day average, indicating rising investor participation despite the price weakness — but does this reflect conviction or caution?

Strike Price Analysis: Moneyness and Distance from Underlying

The put strikes in focus range from Rs 680 to Rs 730, with the underlying at Rs 721.25. The Rs 730 strike is slightly in-the-money (ITM) by about 1.2%, while Rs 720 and Rs 710 are out-of-the-money (OTM) by 0.15% and 1.5% respectively. The Rs 700 and Rs 680 strikes are further OTM, at 2.97% and 5.6% below the current price.

This distribution suggests a layered approach: the ITM and near-ATM strikes (Rs 730, Rs 720) could be used for directional bearish bets or protective hedges, while the deeper OTM strikes (Rs 700, Rs 680) are more likely for hedging against a sharper decline or for put writing strategies. The proximity of the Rs 730 strike to the current price is particularly notable given the stock’s recent weakness.

Interpreting the Put Activity: Bearish, Protective, or Bullish?

Put option activity is inherently ambiguous. The Rs 730 and Rs 720 strikes, with the highest open interest of 15,058 and 9,124 contracts respectively, suggest significant positioning close to the money. Given the stock’s recent downtrend and trading below all key moving averages, this could indicate bearish sentiment. However, the presence of large volumes at OTM strikes Rs 700 and Rs 680, combined with rising delivery volumes, points to a protective hedging motive as well.

Put writing is another possibility, especially at the Rs 680 strike where open interest is relatively modest at 5,869 contracts despite 2,526 contracts traded. Put sellers may be collecting premium, anticipating the stock will not fall below this level by expiry. This is consistent with the stock’s proximity to a technical support zone near Rs 715, which could limit downside risk.

Thus, the put activity likely reflects a combination of fresh bearish bets near the money and hedging of existing long positions further out-of-the-money. The mixed signals underscore the importance of connecting options data with cash market trends — how should investors interpret these conflicting cues?

Open Interest and Contracts Analysis

The open interest (OI) at the Rs 730 strike stands at 15,058 contracts, with 3,292 contracts traded on the day, indicating both fresh and existing positioning. The Rs 700 strike has an OI of 11,977 with 3,522 contracts traded, while Rs 710 and Rs 720 strikes show OIs of 9,563 and 9,124 respectively, with active trading volumes.

The ratio of contracts traded to open interest varies between 0.22 and 0.38 across strikes, suggesting a mix of fresh trades and adjustments to existing positions. The relatively high OI at near-ATM strikes supports the view that these puts are being used for either directional bets or hedging close to current levels, while the lower OI at Rs 680 with a moderate trade count hints at put writing activity.

Cash Market Context: Technicals and Delivery Volumes

HDFC Bank Ltd. is 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 three-day decline of 1.36% and underperformance relative to its sector (-1.16% today) reinforce this trend.

However, delivery volumes rose 6.44% on 26 August to 1.47 crore shares, indicating increased investor participation despite the price weakness. This divergence between price and delivery volume suggests some investors may be accumulating or holding positions, which aligns with the hedging interpretation of the put activity. The Rs 680 to Rs 700 strikes roughly correspond to a support zone near the 52-week low, which could be a natural floor for put sellers.

Conclusion: Protective Hedging with a Bearish Undertone

The put option activity on HDFC Bank Ltd. ahead of the 29 September expiry reveals a nuanced picture. The concentration of contracts at near-ATM strikes Rs 720 and Rs 730, combined with the stock’s technical weakness, suggests some directional bearish positioning. Yet, the significant volume at deeper OTM strikes Rs 680 and Rs 700, alongside rising delivery volumes, points to protective hedging by long holders seeking to guard against further downside.

Put writing activity at the Rs 680 strike also cannot be ruled out, indicating some market participants are willing to collect premium, expecting the stock to hold above this support level. This blend of strategies reflects the complexity of interpreting put activity without the full context of individual investor motives.

With the stock below all key moving averages and near its 52-week low, the options market is signalling caution but not outright capitulation — should investors consider this a time to hedge or to watch for a potential rebound?
