Robust Call Option Volumes at Key Strike Prices
Data from the derivatives market reveals that HDFC Bank’s call options have been among the most actively traded contracts in recent sessions. The expiry on 30 March 2026 has attracted substantial interest, particularly at strike prices ranging from ₹770 to ₹800. The highest volume was recorded at the ₹800 strike, with 9,285 contracts traded, generating a turnover of approximately ₹73.03 lakhs and an open interest of 16,271 contracts. This level of open interest suggests a strong concentration of bullish bets anticipating a price recovery above this strike.
Close behind, the ₹780 strike saw 6,959 contracts traded with a turnover of ₹150.04 lakhs and an open interest of 3,591, while the ₹790 strike recorded 6,828 contracts with ₹84.50 lakhs turnover and 4,143 open interest. The ₹770 and ₹785 strikes also attracted notable volumes, with 5,713 and 5,119 contracts traded respectively, indicating a broad-based interest across near-the-money call options.
Underlying Price Context and Technical Challenges
Despite this active call option interest, the underlying stock price of HDFC Bank closed at ₹765.85 on 27 March 2026, down 2.32% on the day and underperforming its sector by 0.67%. The stock is trading below all major moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — signalling a bearish technical setup. It is also just 3.24% above its 52-week low of ₹741.05, reflecting recent weakness and investor caution.
Intraday, the stock touched a low of ₹763, marking a continuation of a short-term downtrend after two consecutive days of gains. Delivery volumes have also declined sharply, with a 29.73% drop against the five-day average, suggesting waning investor participation amid the recent sell-off.
Mojo Score Upgrade Reflects Mixed Sentiment
HDFC Bank’s MarketsMOJO score currently stands at 51.0, categorised as a ‘Hold’ rating, an upgrade from a previous ‘Sell’ grade on 27 February 2026. This shift indicates a tempered optimism among analysts, recognising the bank’s large-cap stature and fundamental strength while acknowledging near-term headwinds. The market cap remains robust at ₹12,03,300 crores, underscoring the stock’s significance within the private sector banking space.
Expiry Dynamics and Investor Positioning
The concentration of call option open interest at strikes above the current market price suggests that traders are positioning for a potential rebound in HDFC Bank’s shares in the coming days. The ₹800 strike, in particular, stands out as a critical resistance level, with the largest open interest indicating expectations that the stock could test or surpass this level before expiry.
However, the relatively high volumes at slightly lower strikes such as ₹770 and ₹780 also imply that some investors are hedging or speculating on a more modest recovery. The mixed strike price interest reflects a cautious bullish stance, with market participants balancing optimism against the backdrop of recent technical weakness and sectoral pressures.
Sector and Market Comparison
HDFC Bank’s 1-day return of -2.12% lagged behind the private sector banking sector’s decline of -1.52% and the broader Sensex’s fall of -1.18%. This relative underperformance highlights the stock’s vulnerability amid broader market volatility. Nevertheless, the liquidity profile remains strong, with the stock’s average traded value supporting sizeable trade sizes up to ₹153.67 crores, ensuring that option and equity market participants can execute large positions without significant slippage.
Implications for Investors
For investors and traders, the heavy call option activity in HDFC Bank ahead of the March expiry offers valuable insights. The elevated open interest at strikes above the current price signals a degree of confidence in a near-term price recovery, potentially driven by expectations of positive corporate developments or sectoral tailwinds. However, the prevailing technical weakness and declining delivery volumes counsel caution.
Investors should monitor the stock’s ability to reclaim key moving averages and observe whether the open interest at higher strikes translates into actual price gains. A sustained move above ₹780-₹800 could validate the bullish positioning, while failure to break these levels may result in profit-taking and further downside pressure.
Conclusion
HDFC Bank’s derivatives market activity ahead of the 30 March 2026 expiry reveals a nuanced picture of investor sentiment. While call option volumes and open interest point to a cautiously optimistic outlook, the underlying price action and technical indicators suggest that the stock remains under pressure. Market participants will be closely watching the interplay between these factors in the final days before expiry to gauge the bank’s near-term trajectory within the private sector banking sector.
