HDFC Bank Sees Heavy Call Option Activity Ahead of March Expiry

Recent Price Performance and Market Context

HDFC Bank’s stock closed at ₹785.85 on 19 March 2026, hovering just 2.69% above its 52-week low of ₹770. The stock has underperformed its sector by 1.16% on the day and has declined by 6.39% over the last three consecutive sessions. Intraday, it touched a low of ₹781, marking a 2.15% drop. Notably, the share price is trading below all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — signalling a sustained bearish momentum.

Investor participation has, however, risen sharply, with delivery volume on 19 March surging to 10.34 crore shares, a 342.52% increase over the five-day average. This heightened activity indicates that despite the price weakness, market participants are actively positioning themselves, possibly anticipating a reversal or capitalising on volatility.

Call Option Activity: Strike Prices and Volumes

The most active call options for HDFC Bank are concentrated around strike prices ranging from ₹780 to ₹850, all expiring on 30 March 2026. The underlying stock price at ₹785.85 places the lower strikes (₹780, ₹785, ₹795) near-the-money, while the higher strikes (₹820, ₹850) are out-of-the-money.

Among these, the ₹820 strike call option recorded the highest number of contracts traded at 8,764, with a turnover of ₹328.74 lakhs and an open interest of 14,950 contracts. This substantial open interest at an out-of-the-money strike suggests strong speculative or hedging interest anticipating a price rally beyond ₹820 within the expiry timeframe.

Close behind, the ₹795 strike call saw 6,632 contracts traded, generating ₹584.71 lakhs in turnover and holding an open interest of 2,872 contracts. The ₹780 and ₹785 strikes also exhibited robust activity, with 5,249 and 4,893 contracts traded respectively, and turnovers exceeding ₹555 lakhs combined. The ₹850 strike, despite being the highest strike price, recorded 5,089 contracts traded but with a relatively modest turnover of ₹62.42 lakhs, reflecting lower premium values at this level.

Interpreting the Bullish Positioning

The concentration of call option trades at strikes above the current market price indicates a predominantly bullish sentiment among option traders. Investors appear to be positioning for a potential rebound or rally in HDFC Bank’s share price over the next ten days. The large open interest at ₹820 and ₹850 strikes further underscores expectations of upward price movement, possibly driven by upcoming corporate developments or broader market recovery.

However, the stock’s recent downtrend and trading below all major moving averages caution against excessive optimism. The divergence between option market bullishness and spot market weakness may also reflect hedging strategies by institutional investors or arbitrageurs seeking to capitalise on volatility rather than directional conviction alone.

Mojo Score and Analyst Ratings

HDFC Bank currently holds a Mojo Score of 51.0, placing it in the ‘Hold’ category. This represents an upgrade from its previous ‘Sell’ rating as of 27 February 2026, reflecting some improvement in underlying fundamentals or market sentiment. The bank’s large-cap status and market capitalisation of ₹12,30,897 crore underscore its significance in the private sector banking space.

Despite the recent price weakness, the upgrade suggests that analysts see potential stabilisation or recovery in the medium term. Investors should weigh this cautiously against the prevailing bearish technical signals and the stock’s underperformance relative to the Sensex, which gained 1.08% on the same day.

Expiry Patterns and Liquidity Considerations

With the 30 March 2026 expiry approaching, option traders are actively adjusting positions. The high turnover in call options, particularly at strikes ₹780, ₹795, and ₹820, indicates significant liquidity and interest. The stock’s liquidity profile supports sizeable trades, with a 5-day average traded value allowing for trade sizes up to ₹110.96 crore, ensuring smooth execution for institutional participants.

The open interest data reveals that the ₹850 strike has amassed 18,291 contracts, the highest among all strikes, signalling a strong speculative or hedging interest at this level. This could imply that traders are betting on a sharp upside move or using these options as part of complex strategies such as spreads or collars to manage risk.

Investor Takeaways and Outlook

For investors, the current scenario presents a nuanced picture. The heavy call option activity at strikes above the current price suggests optimism about a near-term rebound in HDFC Bank’s shares. However, the persistent downtrend and trading below all major moving averages warrant caution.

Those bullish on the stock may consider the call option volumes and open interest as indicators of potential upside, but should remain mindful of the risks posed by the broader market environment and sector performance. Conversely, the elevated open interest at higher strikes could also be interpreted as hedging by institutional players, signalling uncertainty.

Given the bank’s large-cap stature and recent Mojo Score upgrade, a stabilisation or gradual recovery cannot be ruled out. Nonetheless, investors should monitor price action closely, especially as the 30 March expiry approaches, to gauge whether the bullish option positioning translates into sustained upward momentum in the underlying stock.
