HDFC Bank Sees Surge in Call Option Activity Amid Mixed Technical Signals

Robust Call Option Volumes Highlight Investor Optimism

On 16 February 2026, HDFC Bank’s call options expiring on 24 February attracted substantial trading volumes, with 5,402 contracts exchanged at the ₹910 strike and 6,549 contracts at the ₹920 strike. The turnover for these strikes was ₹447.45 lakhs and ₹362.36 lakhs respectively, underscoring strong investor interest. Open interest figures further reinforce this trend, with 2,485 contracts outstanding at ₹910 and a more pronounced 7,784 contracts at ₹920, indicating that market participants are positioning for a potential rally above these levels.

This heightened activity in call options suggests a strategic bet on the stock’s price appreciation, as traders seek to capitalise on anticipated upward momentum. The underlying stock price of ₹917.05 is currently hovering just below the ₹920 strike, making the latter a critical level to watch in the coming days.

Stock Performance and Technical Context

Despite the bullish options activity, HDFC Bank’s mojo grade was downgraded from Hold to Sell on 9 February 2026, with a current mojo score of 48.0. The downgrade reflects concerns over the bank’s near-term fundamentals and valuation metrics. The market cap grade remains at 1, indicating a large-cap status with a market capitalisation of ₹13,93,622 crores.

On the price front, the stock outperformed its private sector banking peers by 0.8% on the day, delivering a 1.50% gain compared to the sector’s 0.52% and the Sensex’s marginal 0.06% rise. This performance marks a reversal after seven consecutive days of decline, signalling a potential shift in investor sentiment.

However, technical indicators present a mixed picture. HDFC Bank is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, suggesting that the stock remains under pressure in the medium to long term. Notably, delivery volume surged to 4.35 crore shares on 13 February, a 137.98% increase over the five-day average, indicating rising investor participation and liquidity. The stock’s liquidity supports trade sizes up to ₹64.81 crores based on 2% of the five-day average traded value, making it accessible for institutional and retail investors alike.

Expiry Patterns and Strike Price Concentration

The concentration of call option activity at the ₹910 and ₹920 strikes for the 24 February expiry is particularly telling. The ₹910 strike, with 5,402 contracts traded and an open interest of 2,485, represents a near-the-money position, while the ₹920 strike, with even higher open interest of 7,784 contracts, indicates a strong speculative interest in the stock surpassing this level.

Such clustering of open interest near the current underlying price often acts as a magnet for price movement, as traders hedge or unwind positions approaching expiry. The substantial turnover at these strikes also suggests that market makers and institutional players are actively managing risk and positioning for potential volatility in the final week before expiry.

Investor Sentiment and Market Implications

The bullish positioning in call options contrasts with the recent downgrade in fundamental ratings, highlighting a divergence between short-term market optimism and longer-term caution. This dynamic is not uncommon in large-cap banking stocks, where macroeconomic factors, regulatory developments, and sectoral trends can influence sentiment rapidly.

Investors should note that while the stock has shown resilience with a 1.50% gain on the day, it remains below key moving averages, signalling that confirmation of a sustained uptrend is pending. The elevated delivery volumes and liquidity provide a supportive backdrop for trading activity, but the downgrade to a Sell mojo grade advises prudence.

Strategic Takeaways for Investors

For investors analysing HDFC Bank’s current market positioning, the surge in call option activity at strikes just above the current price suggests a cautiously optimistic outlook among traders. Those bullish on the stock may view the ₹920 strike as a key resistance level to monitor, with a break above potentially triggering further upside momentum.

Conversely, the downgrade in mojo grade and the stock’s position below all major moving averages counsel a measured approach. Investors should weigh the short-term technical signals against the fundamental outlook and broader sector trends before committing to sizeable positions.

Given the stock’s large-cap status and liquidity, it remains a viable candidate for both trading and portfolio allocation, but with an emphasis on risk management and monitoring of expiry-related volatility.

Outlook and Market Context

HDFC Bank operates in the highly competitive private sector banking industry, where macroeconomic factors such as interest rate cycles, credit growth, and regulatory changes play pivotal roles. The recent market activity in options reflects a nuanced view, with traders positioning for potential near-term gains while remaining mindful of underlying risks.

As expiry approaches on 24 February 2026, the interplay between open interest unwinding and fresh positioning will likely dictate price action. Investors should remain vigilant for any shifts in volume patterns or news flow that could influence sentiment.

Conclusion

In summary, HDFC Bank Ltd. is currently at a crossroads, with strong call option activity signalling bullish bets against a backdrop of fundamental caution. The stock’s recent outperformance relative to its sector and the Sensex, combined with rising delivery volumes, suggests growing investor interest. However, the downgrade to a Sell mojo grade and technical weakness below key moving averages warrant careful analysis.

Market participants should closely monitor the ₹910 and ₹920 strike levels as expiry nears, as these will be critical in shaping the stock’s trajectory. A balanced approach that considers both the technical signals and fundamental outlook will be essential for navigating the evolving landscape of this large-cap banking stock.
