Robust Call Option Volumes Signal Bullish Positioning
Data from the derivatives market reveals that the most actively traded call options on HDFC Bank Ltd. are those with a strike price of ₹1,000, expiring on 27 January 2026. A total of 6,863 contracts changed hands, generating a turnover of approximately ₹56.77 crores. Open interest at this strike stands at 7,157 contracts, indicating sustained interest and potential accumulation by traders anticipating a rally.
The underlying stock closed at ₹991.90, just 2.89% shy of its 52-week high of ₹1,020.50, underscoring the proximity to a key resistance level. This near-term expiry call option activity suggests that investors are positioning for a breakout above the ₹1,000 mark, which could act as a psychological and technical barrier.
Price and Trend Analysis
Despite underperforming its sector by 0.37% on the day, HDFC Bank has reversed a three-day losing streak, posting a modest gain of 0.22% on 31 December 2025. The stock has traded within a narrow range of ₹7.40, reflecting consolidation ahead of potential directional movement. Notably, the share price remains above its 100-day and 200-day moving averages, signalling a longer-term uptrend, although it currently trades below the 5-day, 20-day, and 50-day averages, indicating short-term caution among traders.
Investor participation has surged, with delivery volumes on 30 December reaching 2.27 crore shares, a remarkable 183.52% increase compared to the five-day average. This heightened activity suggests renewed confidence among long-term holders and fresh buying interest, which could provide support for the stock in the coming weeks.
Market Capitalisation and Quality Metrics
HDFC Bank Ltd. boasts a market capitalisation of ₹15,27,842.36 crore, firmly placing it in the large-cap category. The company’s Mojo Score stands at 72.0, reflecting a solid Buy rating, although this represents a slight downgrade from a previous Strong Buy grade assigned on 22 December 2025. The market cap grade is rated at 1, indicating top-tier size and liquidity, which is further supported by the stock’s ability to handle trade sizes of up to ₹35.57 crore based on 2% of the five-day average traded value.

Expiry Patterns and Investor Sentiment
The January 2026 expiry is attracting significant attention, with the ₹1,000 strike price emerging as the focal point for call option buyers. This strike is slightly above the current market price, indicating a moderately bullish outlook among traders who expect the stock to breach this level within the next four weeks. The open interest accumulation at this strike price suggests that investors are not only speculating but also hedging positions in anticipation of a positive price movement.
Such concentrated activity in call options often precedes a directional move in the underlying stock, as option buyers seek leveraged exposure to potential gains. The combination of rising delivery volumes and sustained open interest supports the thesis of a bullish trend continuation.
Comparative Sector and Benchmark Performance
While HDFC Bank’s one-day return of 0.22% lags behind the Private Sector Bank sector’s 0.65% gain and the Sensex’s 0.68% rise, the stock’s technical positioning and option market activity suggest it is poised for a catch-up rally. The bank’s resilience near its 52-week high and the recent trend reversal after a brief correction period highlight underlying strength relative to peers.
Investors should note that the stock’s current trading range and moving average dynamics imply a period of consolidation, which may resolve with a decisive breakout or pullback depending on broader market cues and sectoral momentum.

Outlook and Investor Considerations
Given the current market dynamics, HDFC Bank Ltd. remains a compelling stock for investors with a bullish medium-term outlook. The active call option interest at the ₹1,000 strike price for the January expiry reflects confidence in the bank’s ability to sustain its upward momentum. However, traders should remain mindful of the stock’s short-term moving average resistance and the broader market environment, which could influence price volatility.
With a Mojo Score of 72.0 and a Buy rating, the bank continues to be favoured by analysts, although the recent downgrade from Strong Buy signals a need for cautious optimism. The stock’s large-cap status and liquidity profile make it suitable for institutional and retail investors alike, while the rising delivery volumes indicate growing conviction among shareholders.
In summary, the surge in call option activity ahead of the January expiry, combined with technical and fundamental strengths, positions HDFC Bank Ltd. as a key stock to watch in the private sector banking space as the new year unfolds.
