Rs 700 Puts — 2.2% Above Current Price — Draw 3,198 Contracts on HDFC Bank Ltd.

Put Options Event and Cash Market Context

On 11 Sep 2026, HDFC Bank Ltd. saw significant put option activity ahead of the 29 Sep 2026 expiry. The Rs 700 strike put contracts numbered 3,198, with a turnover of ₹4.03 crores and open interest standing at 14,929 contracts. Other notable strikes included Rs 690 (5,918 contracts traded), Rs 670 (6,187 contracts), Rs 660 (3,720 contracts), and Rs 650 (3,901 contracts), all expiring on the same date.

The underlying stock closed at Rs 685.25, down 1.34% on the day, hitting a new 52-week low. The stock is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a sustained downtrend. Delivery volumes rose 12.34% compared to the 5-day average, suggesting increased investor participation despite the decline.

The combination of heavy put activity and a falling stock price raises the question: does this put buying signal bearish positioning or protective hedging?

Strike Price Analysis: Moneyness and Distance

The Rs 700 put strike sits approximately 2.2% above the current market price of Rs 685.25, making it an in-the-money (ITM) put option. Other active strikes such as Rs 690 and Rs 670 are also close to the money, with Rs 670 about 2.2% out-of-the-money (OTM) relative to the current price. The Rs 650 and Rs 660 strikes are further OTM, roughly 5.1% and 3.6% below the current price respectively.

ITM and near-the-money put buying often suggests directional bearish bets, as buyers pay a premium for downside protection or profit from expected declines. However, the presence of significant volume at OTM strikes like Rs 650 and Rs 660 complicates the picture, as these could represent hedging against deeper falls or put writing strategies.

Given the expiry is less than three weeks away, the strike distance is a critical clue: buyers of ITM puts may be positioning for continued weakness, while OTM put activity could be protective or speculative.

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

Put option activity can be ambiguous. The Rs 700 strike’s ITM status and the stock’s downtrend support a bearish interpretation, where traders anticipate further declines. Yet, the sizeable open interest at strikes below the current price, combined with the stock’s recent volatility, suggests some investors may be hedging existing long positions to limit losses.

Put writing, or selling puts to collect premium, is another possibility, especially at OTM strikes like Rs 650 and Rs 660 where premiums are lower and risk of assignment is less immediate. Sellers in this scenario are betting the stock will not fall below these levels by expiry, a mildly bullish stance.

Overall, the data points to a mixed strategy environment: directional bearish bets at ITM strikes, protective hedging at near-OTM strikes, and some put writing at deeper OTM levels. The question remains: which strategy dominates the options market for HDFC Bank Ltd.?

Open Interest and Contracts: Fresh Positioning or Adjustments?

The open interest at the Rs 700 strike is 14,929 contracts, significantly higher than the 3,198 contracts traded on the day, indicating that much of the activity is fresh buying or closing of existing positions. The ratio of contracts traded to open interest is roughly 0.21, suggesting a moderate turnover relative to the total outstanding positions.

At the Rs 670 strike, 6,187 contracts traded against an open interest of 4,889, implying fresh positioning or rollovers. The Rs 690 strike also shows a similar pattern with 5,918 contracts traded and 7,335 open interest. These figures indicate active repositioning in the put market, with traders adjusting hedges or directional bets as expiry approaches.

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 — signalling a bearish technical setup. The stock’s recent 1.34% decline and new 52-week low reinforce this downtrend.

However, delivery volumes rose 12.34% on 10 Sep 2026 compared to the 5-day average, indicating rising investor participation despite the price fall. This suggests some investors may be accumulating or holding positions, which could explain the hedging put activity rather than outright bearish bets.

The Rs 700 put strike sits above the current price, roughly aligning with a resistance zone rather than immediate support, which supports the idea that put buyers may be protecting gains or limiting downside risk rather than speculating on a sharp drop.

Delivery Volume and Market Liquidity

Liquidity remains robust, with the stock’s traded value supporting a trade size of approximately ₹33.81 crores based on 2% of the 5-day average traded value. This liquidity facilitates active options trading and allows for efficient hedging or speculative strategies.

The increased delivery volume alongside falling prices may indicate a divergence between short-term selling pressure and longer-term investor conviction, which could be a factor behind the mixed put activity observed.

Conclusion: Protective Hedging Dominates Put Activity

The put option activity in HDFC Bank Ltd. ahead of the 29 Sep 2026 expiry reveals a complex picture. The ITM Rs 700 puts and near-the-money strikes suggest some bearish positioning, consistent with the stock’s downtrend and technical weakness.

However, the presence of significant open interest and fresh contracts at OTM strikes, combined with rising delivery volumes and liquidity, points to a substantial element of protective hedging by investors seeking to limit downside risk rather than outright bearish bets. Put writing at deeper OTM strikes may also be present, reflecting a cautiously optimistic stance among some market participants.

Given these factors, the most plausible interpretation is that the heavy put activity largely reflects hedging of existing long positions amid a weak market backdrop, rather than a pure directional bearish conviction. The question remains: should investors consider this protective stance as a signal to adjust their own exposure to HDFC Bank Ltd.?
