HDFC Bank Sees Heavy Put Option Activity Ahead of March Expiry

Put Option Activity Highlights

Data from the derivatives market reveals that HDFC Bank’s put options have been the most actively traded among private sector banks, with significant volumes concentrated at strike prices near the current underlying value of ₹869. The 870 strike price put option led the pack with 3,016 contracts traded, generating a turnover of ₹291.78 lakhs and an open interest of 5,374 contracts. This is closely followed by the 800 strike price put, which saw 2,187 contracts traded and an open interest of 3,187, albeit with a lower turnover of ₹30.55 lakhs.

Other notable strike prices include 850 and 860, with 2,146 and 1,753 contracts traded respectively, and open interest figures of 2,540 and 2,275. The turnover at these strikes was ₹122.99 lakhs and ₹133.73 lakhs, indicating robust investor interest in downside protection or speculative bearish bets.

Market Context and Stock Performance

HDFC Bank’s stock closed at ₹869, hovering just 3.64% above its 52-week low of ₹835.03. The stock has experienced a mild decline of 0.23% on the day, underperforming the sector’s modest gain of 0.11% and the Sensex’s 0.53% rise. Notably, the stock has broken a six-day losing streak with a slight uptick, suggesting a possible short-term trend reversal.

However, technical indicators remain cautious. The bank’s share price is trading below all major moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — signalling sustained downward pressure. Rising delivery volumes, which increased by 3.05% to 2.36 crore shares on 4 March, point to heightened investor participation, but the overall sentiment appears mixed.

Investor Positioning and Hedging Implications

The concentration of put option activity at strike prices ranging from 800 to 870 suggests that market participants are positioning for potential downside risk or are actively hedging existing long exposures. The highest open interest at the 870 strike, which is slightly above the current market price, indicates a significant number of investors are seeking protection against a decline below this level.

Meanwhile, the sizeable open interest at the 800 strike price, which is nearly 8% below the current price, points to more aggressive bearish bets or longer-term hedging strategies. The disparity in turnover between the 870 and 800 strikes also reflects differing investor intentions, with the higher strike price options attracting more premium and liquidity.

Mojo Score and Analyst Ratings

HDFC Bank currently holds a Mojo Score of 51.0, categorised as a Hold, an improvement from its previous Sell rating as of 27 February 2026. This upgrade reflects a cautious optimism based on recent financial metrics and market trends, although the bank’s Market Cap Grade remains at 1, indicating a very large capitalisation of ₹13,36,498 crore.

The Hold rating aligns with the mixed technical signals and the active put option interest, suggesting that while downside risks are acknowledged, the stock is not yet a definitive sell. Investors should weigh these factors carefully, considering both the bank’s fundamental strength and the evident market hedging activity.

Expiry Patterns and Future Outlook

The expiry date of 30 March 2026 is a critical juncture for HDFC Bank’s options market. The clustering of put options around the 850 to 870 strikes indicates that traders are closely monitoring this range for potential price support or breakdown. Given the stock’s proximity to its 52-week low and the recent uptick after a prolonged decline, the coming weeks will be pivotal in determining the next directional move.

Should the stock breach the 850 level decisively, the heavy put open interest at 800 could accelerate bearish momentum. Conversely, a sustained recovery above 870 could see put option sellers unwinding positions, potentially easing downward pressure.

Comparative Sector and Market Performance

Within the private sector banking space, HDFC Bank’s performance has been relatively subdued. While the sector index posted a modest gain of 0.11% on the day, HDFC Bank declined by 0.23%, underperforming the broader Sensex, which rose 0.53%. This divergence highlights the cautious stance investors are taking on the bank amid macroeconomic uncertainties and sector-specific challenges.

Liquidity remains robust, with the stock’s average traded value supporting trade sizes up to ₹68.08 crore, ensuring that institutional investors can execute sizeable transactions without significant market impact. This liquidity is crucial for options market participants who require efficient entry and exit points for their hedging or speculative strategies.

Conclusion: Navigating the Put Option Surge

The heightened put option activity in HDFC Bank ahead of the March expiry underscores a market bracing for volatility and potential downside risk. Investors and traders should interpret this as a signal to reassess their exposure and risk management frameworks. While the stock’s recent uptick after a prolonged decline offers some hope of stabilisation, the technical backdrop and options market positioning counsel caution.

For those holding long positions, protective puts at strikes between 850 and 870 may provide a prudent hedge. Conversely, bearish traders may find opportunities in the elevated open interest at lower strikes, particularly 800, to capitalise on any further weakness. Ultimately, the interplay between fundamental strength and market sentiment will dictate HDFC Bank’s trajectory in the near term.
