Rs 650 Puts — 5.7% Below Current Price — Draw 2,737 Contracts on HDFC Bank Ltd.

Put Options Event and Cash Market Context

The most active put strikes for HDFC Bank Ltd. on 10 Sep 2026 were Rs 700, Rs 690, Rs 680, and Rs 650, with contracts traded numbering 3,112, 5,236, 3,706, and 2,737 respectively. The Rs 700 strike led with 14,924 open interest, followed by Rs 680 with 8,534 and Rs 690 with 7,402. The Rs 650 strike, despite lower open interest at 4,944, saw a significant fresh volume of 2,737 contracts traded, indicating active positioning near this lower strike.

The underlying stock closed at Rs 689.20, hovering just 0.25% above its 52-week low of Rs 687.10. Notably, the stock has gained modestly after three consecutive days of decline, trading in a narrow range of Rs 0.35 on the day. Delivery volumes rose sharply by 90.04% to 2.89 crore shares on 9 Sep, signalling increased investor participation despite the subdued price movement.

The stock remains below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, reflecting a persistent downtrend. This technical backdrop is critical to interpreting the put activity — is the put buying a hedge against further declines or a directional bearish bet?

Strike Price Analysis: Moneyness and Intent

The Rs 650 put strike sits approximately 5.7% out-of-the-money (OTM) relative to the current price of Rs 689.20. The Rs 680 and Rs 690 strikes are closer to at-the-money (ATM) territory, at 1.3% and 0.1% below the underlying price respectively, while the Rs 700 strike is in-the-money (ITM) by about 1.5%.

OTM puts like Rs 650 typically serve as protective instruments, allowing holders to limit downside risk beyond a certain threshold. Conversely, ITM and ATM puts often indicate more immediate bearish positioning or spread strategies. The significant volume at Rs 650 suggests a preference for downside protection at a level comfortably below current prices, rather than an outright bet on a sharp near-term decline.

Given the stock's proximity to its 52-week low and the fact that it trades below all major moving averages, the Rs 650 strike may also correspond to a technical support zone, making it a logical level for hedging rather than speculative bearishness — does this strike reflect a safety net for longs or a bearish conviction?

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

Put option activity can be ambiguous. The surge in contracts at Rs 650 and other strikes could represent three broad scenarios: protective hedging by existing long holders, directional bearish bets by new entrants, or put writing (selling) by bullish investors collecting premium.

Given the stock's recent modest recovery after a decline and its position below key moving averages, the Rs 650 puts are likely being purchased as a hedge against further downside risk rather than as a pure bearish wager. The OTM nature of the Rs 650 strike supports this, as outright bearish bets tend to cluster closer to ATM or ITM strikes.

Put writing is less likely at Rs 650 given the relatively lower open interest compared to the Rs 700 strike, which shows higher open interest but less fresh volume. The Rs 700 ITM puts may be part of spread strategies or protective collars, but the fresh activity at Rs 650 points to new hedging rather than premium collection.

Open Interest and Contracts: Fresh Positioning Insights

The ratio of contracts traded to open interest at the Rs 650 strike is approximately 0.55 (2,737 contracts traded against 4,944 open interest), indicating a moderate level of fresh activity but not an overwhelming surge. In contrast, the Rs 700 strike shows a much larger open interest of 14,924 with 3,112 contracts traded, suggesting more established positions there.

This pattern implies that the Rs 650 put activity is likely new hedging or protective buying rather than unwinding or aggressive bearish positioning. The fresh volume at this strike, combined with the stock's technical context, supports the interpretation of cautious protection rather than outright bearish conviction.

Cash Market Context: Technicals and Delivery Volumes

HDFC Bank Ltd. remains below all major moving averages, signalling a downtrend, but the recent three-day gain after a decline suggests some short-term recovery attempts. The Rs 650 strike aligns roughly with a support zone below the 50-day moving average, reinforcing the idea that put buyers are seeking protection against a pullback to this level rather than expecting a collapse.

Delivery volumes have risen sharply by 90.04% to 2.89 crore shares, indicating increased investor participation despite the narrow price range. This heightened delivery volume amid a subdued price move may explain why put buyers are hedging: the rally lacks strong delivery-backed conviction, making downside protection prudent.

Conclusion: Protective Hedging Dominates Put Activity

The put option activity in HDFC Bank Ltd. on 10 Sep 2026, particularly at the Rs 650 strike, appears to be driven primarily by protective hedging rather than outright bearish positioning or put writing. The strike price's distance from the current market price, combined with the stock's technical downtrend and recent modest recovery, supports this interpretation.

While some bearish bets may exist at the ATM and ITM strikes, the fresh volume and open interest patterns suggest that investors are seeking downside protection against further declines rather than expecting an imminent drop. The elevated delivery volumes amid a narrow price range further reinforce the rationale for hedging.

With the stock trading below all major moving averages but showing signs of short-term resilience, should investors consider this put activity as a signal to hedge or a warning of deeper weakness ahead?
