Rs 740 Puts — 1.2% Above Current Price — Draw 4,191 Contracts on HDFC Bank.

Put Options Event and Cash Market Context

On 20 Aug 2026, HDFC Bank. witnessed significant put option activity ahead of the 25 Aug expiry. The Rs 740 strike saw 4,191 contracts traded, generating a turnover of approximately ₹393.64 lakhs. This was the highest turnover among put strikes for the day, with open interest at 11,208 contracts. Other notable strikes included Rs 720 (6,241 contracts traded) and Rs 730 (4,664 contracts traded), both also showing substantial activity.

The underlying stock closed at Rs 727.45, just 1.45% above its 52-week low of Rs 715.10. The price has been in a narrow range recently, with a modest 0.92% gain on the day, inline with the sector’s 0.87% rise and the Sensex’s 0.52% advance. However, HDFC Bank. remains below all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — indicating a subdued technical backdrop despite the slight uptick. Does this mixed technical picture explain the put activity?

Strike Price Analysis: Moneyness and Distance from Underlying

The Rs 740 put strike is approximately 1.7% out-of-the-money (OTM) relative to the current price of Rs 727.45. Other active strikes such as Rs 730 and Rs 720 are closer to at-the-money (ATM) and slightly in-the-money (ITM) respectively, with Rs 720 about 1% below the current price. The Rs 700 strike, further ITM by nearly 3.7%, also saw 4,080 contracts traded but with lower open interest (9,712 contracts).

OTM puts like Rs 740 typically serve as protective hedges for existing long positions, especially when the stock is trading below key moving averages and near a 52-week low. The proximity of the Rs 740 strike to the current price suggests that traders may be seeking downside protection against further weakness rather than outright bearish bets. Could this be a sign of cautious hedging rather than directional pessimism?

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

Put option activity can be ambiguous. Heavy put buying can signal bearish conviction, but it can also represent hedging of long stock holdings or put writing (selling puts) as a bullish strategy. In this case, the Rs 740 strike’s OTM status combined with the stock’s recent modest gains and position below moving averages points towards hedging as the dominant motive.

Bearish positioning would be more likely if the stock were falling sharply and ATM or ITM puts were being aggressively bought. Here, the stock’s narrow trading range and slight recovery after two days of decline suggest investors are protecting gains or limiting downside risk rather than expecting a steep drop. Put writing is less likely given the high turnover and open interest, which indicate fresh buying rather than premium collection by sellers.

Open Interest and Contracts Analysis

The ratio of contracts traded to open interest varies by strike. For Rs 740, 4,191 contracts traded against 11,208 open interest, a ratio of about 0.37, indicating moderate fresh activity but also significant existing positions. The Rs 720 strike shows a higher ratio with 6,241 contracts traded versus 14,360 open interest, suggesting active repositioning or new hedges being established.

These figures imply that the put activity is not purely speculative but includes adjustments to existing hedges or protective strategies. The presence of substantial open interest at multiple strikes near the current price supports the view that investors are managing risk across a range of downside levels rather than betting on a single price collapse.

Cash Market Context: Technicals and Delivery Volumes

HDFC Bank. is trading below all major moving averages, a sign of technical weakness. The stock’s recent 0.92% gain is modest and comes after two days of decline, indicating a tentative recovery rather than a strong uptrend. Delivery volumes on 19 Aug were ₹1.4 crore, down 10.46% from the five-day average, signalling reduced investor participation in the rally.

This thinning delivery volume may explain why investors are seeking downside protection through puts — the rally lacks conviction and could be vulnerable to a pullback. The Rs 740 put strike roughly corresponds to a support zone just above the 50-day moving average, consistent with a hedging strategy to guard against a retreat to technical support levels. Is this cautious positioning a prudent response to the stock’s technical setup?

Key Data at a Glance

Conclusion: Protective Hedging Dominates Put Activity

The heavy put option activity on HDFC Bank. at strikes slightly above and below the current price, combined with the stock’s subdued technical position and modest recent gains, points to a predominance of hedging rather than outright bearish bets. The Rs 740 strike’s OTM status and significant open interest suggest investors are protecting long positions against a potential pullback to support levels rather than expecting a sharp decline.

While some directional bearishness cannot be ruled out, the data does not support a strong conviction of imminent weakness. Put writing appears less likely given the high turnover and open interest, which indicate fresh buying interest in downside protection.
