HDFC Bank Sees Robust Call Option Activity Ahead of March Expiry

Robust Call Option Volumes Highlight Investor Interest

Data from the derivatives market reveals that HDFC Bank’s call options with strike prices of ₹870 and ₹900 expiring on 30 March 2026 have emerged as the most actively traded contracts. Specifically, the ₹900 strike call options recorded 3,906 contracts traded, generating a turnover of approximately ₹206.45 lakhs and an open interest of 16,713 contracts. Meanwhile, the ₹870 strike calls saw 2,945 contracts traded with a turnover of ₹358.77 lakhs and an open interest of 2,374 contracts. These figures underscore a pronounced bullish sentiment among option traders, who appear to be positioning for a potential upside in the near term.

Stock Price and Technical Context

Despite this optimism in the options market, HDFC Bank’s underlying equity has been grappling with headwinds. The stock closed at ₹869.00, hovering just 3.96% above its 52-week low of ₹835.03. It has underperformed the broader Sensex, which gained 0.39% on the same day, while the bank’s sector declined by 0.18%. The stock itself fell by 0.32% on the day, marginally worse than the sector’s performance.

Technically, HDFC Bank is trading below all major moving averages – 5-day, 20-day, 50-day, 100-day, and 200-day – signalling a bearish trend in the short to long term. However, the stock has shown signs of a trend reversal, gaining after six consecutive days of decline, which may be fuelling the bullish call option activity.

Investor Participation and Liquidity

Investor participation has been on the rise, with delivery volumes reaching 2.36 crore shares on 4 March 2026, marking a 3.05% increase over the five-day average delivery volume. This heightened activity suggests that investors are increasingly engaging with the stock, possibly anticipating a turnaround or a technical bounce. The stock’s liquidity remains robust, with a trade size capacity of ₹68.08 crore based on 2% of the five-day average traded value, ensuring that large trades can be executed without significant price impact.

Mojo Score and Rating Update

HDFC Bank currently holds a Mojo Score of 51.0, reflecting a Hold rating, an improvement from its previous Sell grade as of 27 February 2026. This upgrade indicates a cautious optimism from analysts, recognising the bank’s strong market position and large-cap status with a market capitalisation of ₹13,32,573.63 crore, while also acknowledging the recent price weakness and technical challenges. The bank’s market cap grade remains at 1, underscoring its stature as a heavyweight in the private sector banking industry.

Expiry Patterns and Strike Price Significance

The concentration of call option activity at the ₹900 strike price, which is slightly above the current underlying price, suggests that traders are betting on a moderate upside in the coming weeks. The substantial open interest at this strike price further reinforces the view that market participants expect the stock to breach this level by expiry. The ₹870 strike calls, closer to the current price, also show significant activity, indicating a layered approach by investors to hedge or speculate on near-term price movements.

Sectoral and Market Comparisons

Within the private sector banking space, HDFC Bank’s recent underperformance contrasts with the broader sector’s marginal decline of 0.18%. The Sensex’s positive return of 0.39% on the day highlights the stock’s relative weakness. However, the bank’s large market cap and liquidity profile make it a preferred choice for institutional investors, who may be using options to express nuanced views on the stock’s trajectory amid a volatile macroeconomic environment.

Outlook and Investor Considerations

While the surge in call option volumes points to a bullish tilt among derivatives traders, investors should weigh this against the stock’s technical weakness and proximity to its 52-week low. The recent upgrade to a Hold rating by MarketsMOJO reflects a balanced view, suggesting that while the bank’s fundamentals remain intact, near-term price action may be volatile.

Investors with a bullish outlook might consider the active strike prices as potential entry points, but should remain vigilant of broader market trends and sectoral developments. Conversely, cautious investors may prefer to monitor the stock’s ability to sustain gains above key moving averages before committing fresh capital.

Conclusion

HDFC Bank Ltd.’s elevated call option activity ahead of the March expiry highlights a market expectation of a possible rebound, despite recent price softness and technical challenges. The stock’s large-cap status, improving analyst sentiment, and rising investor participation provide a foundation for potential recovery. However, the mixed signals warrant a measured approach, with investors advised to consider both the bullish option positioning and the underlying equity’s technical context in their decision-making process.
