Call Option Activity Highlights
On 16 March 2026, HDFC Bank's call options with a strike price of ₹840 expiring on 30 March 2026 emerged as the most actively traded contracts in the segment. A total of 3,484 contracts changed hands, generating a turnover of approximately ₹289.54 lakhs. Open interest at this strike stands at 5,661 contracts, indicating sustained investor interest and potential positioning ahead of expiry.
The underlying stock price at the time was ₹837.90, just ₹27.90 shy of the call strike price, suggesting that traders are betting on a modest upside in the near term. This activity reflects a bullish tilt, with market participants anticipating a possible rebound or at least a stabilisation above the current levels.
Stock Price and Technical Context
HDFC Bank's share price has been under pressure recently, trading only 3.27% above its 52-week low of ₹812. The stock has recorded a slight decline of 0.28% on the day, underperforming the private sector banking sector's gain of 0.22% and the Sensex's 0.17% rise. Despite this, the stock has shown resilience with a one-day consecutive gain streak, albeit with a marginal return of -0.14% over this period, indicating a volatile but potentially stabilising trend.
Technically, the stock is positioned above its 5-day moving average but remains below its 20-day, 50-day, 100-day, and 200-day moving averages. This mixed technical picture suggests short-term support but longer-term resistance, which may be influencing the cautious optimism seen in the call option market.
Investor Participation and Liquidity
Investor participation has increased notably, with delivery volume on 16 March rising by 15.78% to 3.01 crore shares compared to the five-day average. This uptick in delivery volume indicates stronger conviction among investors, possibly reflecting accumulation at current price levels.
Liquidity remains robust, with the stock capable of supporting trade sizes up to ₹81.06 crore based on 2% of the five-day average traded value. This liquidity profile supports active options trading and provides a conducive environment for institutional and retail investors alike to execute sizeable trades without significant market impact.

Mojo Score and Rating Update
MarketsMOJO assigns HDFC Bank a Mojo Score of 51.0, categorising it with a Hold grade as of 27 February 2026, an upgrade from its previous Sell rating. This shift reflects an improved outlook based on recent financial metrics and market positioning, though the score indicates that the stock is not yet a strong buy. The large-cap bank's fundamentals remain solid, but near-term headwinds and valuation concerns temper enthusiasm.
Expiry Patterns and Market Sentiment
The concentration of call option activity at the ₹840 strike price, close to the current market price, suggests that traders are positioning for a potential upside of approximately 0.25% from the underlying value. The expiry date of 30 March 2026 is just under two weeks away, which often leads to increased option volume as investors adjust their portfolios ahead of expiry.
Such activity can also indicate hedging strategies by institutional players or speculative bets by retail investors anticipating a rebound in the banking sector or a positive trigger in the broader market environment.
Comparative Sector and Market Performance
While HDFC Bank has slightly lagged the sector and benchmark indices on the day, its liquidity and active options market suggest it remains a key focus for traders. The private sector banking sector has shown modest gains, buoyed by improving credit growth and stable asset quality trends. However, macroeconomic uncertainties and regulatory developments continue to influence investor sentiment.
Against this backdrop, the active call option interest in HDFC Bank may be signalling a cautious but constructive outlook, with market participants expecting the stock to outperform or at least hold steady in the near term.

Investor Takeaways and Outlook
For investors, the current surge in call option activity at near-the-money strikes offers insight into market expectations. While the stock remains close to its yearly lows, the increased open interest and turnover in call options suggest a growing bullish sentiment or at least a hedge against further downside.
Given the Hold rating and the mixed technical indicators, investors should weigh the potential for short-term gains against the risks posed by broader market volatility and sector-specific challenges. The stock’s liquidity and active options market provide flexibility for tactical trades, but a cautious approach remains prudent.
Monitoring the evolution of open interest and price action as the 30 March expiry approaches will be critical for gauging whether this bullish positioning translates into sustained upward momentum or if profit-taking and volatility will dominate.
Conclusion
HDFC Bank Ltd. continues to command significant attention in the options market, with the ₹840 call options expiry on 30 March 2026 attracting the highest volume and turnover among its peers. This activity, combined with a recent upgrade in rating and rising investor participation, paints a picture of cautious optimism amid a challenging market environment. Investors should remain vigilant, balancing the potential for upside with the inherent risks of trading near key technical levels and expiry dates.
