Rs 690 and Rs 700 Puts Draw Heavy Interest as HDFC Bank Ltd. Trades Near 52-Week Low

Put Options Event and Cash Market Context

On 9 September 2026, HDFC Bank Ltd. witnessed heavy put option trading with 3,768 contracts at the Rs 690 strike and 6,374 contracts at the Rs 700 strike. The turnover for these strikes was ₹173.65 lakhs and ₹461.54 lakhs respectively, indicating substantial premium flow. Open interest stands at 6,370 contracts for Rs 690 puts and 13,447 contracts for Rs 700 puts, suggesting these are not merely one-off trades but part of a broader positioning ahead of the 29 September expiry.

The underlying stock price of Rs 696.60 is marginally below the Rs 700 strike and just above Rs 690, placing the Rs 700 puts at-the-money (ATM) and Rs 690 puts slightly in-the-money (ITM). This proximity to the current price is critical in interpreting the intent behind the put activity — is this a directional bearish bet or a protective hedge?

Strike Price Analysis: Moneyness and Implications

The Rs 700 strike sits approximately 0.5% above the current price, making it ATM, while the Rs 690 strike is about 0.9% below, categorising it as slightly ITM. Typically, ATM and ITM puts are more expensive and tend to be purchased either as a direct bearish bet or as protection for existing long positions. The closeness of these strikes to the current price suggests that traders are positioning for near-term downside risk or seeking insurance against further declines.

Given that HDFC Bank Ltd. has been on a three-day losing streak, falling 2.11% in that period and underperforming its sector by 0.26% today, the put activity aligns with a cautious stance. However, the presence of significant open interest at these strikes also opens the possibility of put writing, where sellers collect premium expecting the stock to hold above these levels.

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

Put options inherently carry ambiguous signals. The Rs 700 ATM puts could indicate fresh bearish positioning, anticipating further declines below this level by expiry. Conversely, the Rs 690 ITM puts might be part of a spread strategy or protective hedging for long holders seeking downside insurance near recent lows.

Alternatively, the high open interest and turnover could reflect put writing, where traders sell puts at these strikes to collect premium, implicitly expressing confidence that the stock will not breach these levels. This is plausible given the stock’s liquidity and the fact that the Rs 690 strike is close to a technical support zone.

Notably, the ratio of contracts traded to open interest is approximately 0.59 for Rs 690 puts and 0.47 for Rs 700 puts, indicating a mix of fresh trades and existing positions being adjusted rather than purely new directional bets. This blend complicates a straightforward bearish interpretation — how should investors weigh these competing signals?

Open Interest and Contracts Analysis

The open interest at Rs 700 puts (13,447 contracts) is more than double that at Rs 690 (6,370 contracts), signalling greater interest at the ATM strike. The number of contracts traded on the day (6,374 at Rs 700 and 3,768 at Rs 690) represents a significant turnover relative to open interest, suggesting active repositioning.

This activity could be fresh buying of puts as a bearish hedge or protective measure, but the sizeable open interest also hints at put sellers maintaining their positions. The balance between buyers and sellers is crucial in determining whether the market expects a meaningful decline or is simply managing risk around current levels.

Cash Market Context: Price Momentum and Moving Averages

HDFC Bank Ltd. is trading below all major moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — a technical signal consistent with a bearish trend. The stock’s recent three-day fall of 2.11% and a narrow trading range of Rs 0.45 today reinforce the subdued momentum.

Delivery volumes have declined by 15.63% compared to the five-day average, indicating reduced investor participation in the cash market. This thinning participation may be a factor behind the put activity, as traders seek to hedge against potential volatility in a market lacking strong conviction — does this suggest a cautious stance rather than outright bearishness?

Delivery Volume and Liquidity Considerations

The delivery volume of 1.38 crore shares on 8 September, down 15.63% from the recent average, points to a decline in firm investor commitment. Despite this, the stock remains liquid enough to support trades worth approximately ₹33.47 crore based on 2% of the five-day average traded value, allowing options traders to execute sizeable positions without undue market impact.

This liquidity backdrop supports the possibility of both hedging and put writing strategies, as market participants can efficiently enter and exit positions around key strikes.

Conclusion: Weighing the Signals from Put Activity and Price Action

The heavy put activity at Rs 690 and Rs 700 strikes on HDFC Bank Ltd. reflects a complex interplay of bearish positioning, hedging, and potential put writing. The proximity of these strikes to the current price, combined with the stock’s recent decline and trading below all major moving averages, supports a cautious or defensive stance among options traders.

However, the significant open interest and turnover ratios suggest that not all put activity is purely bearish; some may be protective hedging by long holders or premium collection by put sellers confident the stock will hold above these levels. The reduced delivery volumes and narrow price range further indicate a market in wait-and-see mode rather than one anticipating a sharp fall.

Given these factors, should investors interpret this put activity as a signal to hedge, a sign of conviction in a further decline, or an opportunity to reassess risk exposure?
