HDFC Bank Sees Heavy Call Option Activity Amid Bearish Price Momentum

Call Option Activity Highlights

On 13 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 market. A total of 16,806 contracts changed hands, generating a turnover of approximately ₹1,479.85 lakhs. The open interest for these contracts stands at 6,105, indicating sustained investor interest and potential build-up of bullish bets despite the underlying stock trading at ₹833.30, slightly below the strike price.

The high volume and turnover in these call options suggest that market participants are either hedging existing positions or speculating on a rebound in the stock price before the expiry date. The ₹840 strike price is particularly noteworthy as it is just above the current market price, implying a moderately optimistic outlook from option buyers who anticipate a recovery beyond this level within the next two weeks.

Price Performance and Technical Context

HDFC Bank has been under pressure recently, with the stock hitting a fresh 52-week low of ₹816.90 on the day of reporting. Over the last three trading sessions, the stock has declined by 3.51%, underperforming its sector by 0.41% and the broader Sensex by 0.75%. The stock’s narrow trading range of ₹6.90 on the day reflects subdued volatility, yet the downward momentum remains intact.

Technically, HDFC Bank is trading below all key moving averages – 5-day, 20-day, 50-day, 100-day, and 200-day – signalling a bearish trend across multiple timeframes. This technical weakness contrasts with the heightened call option activity, suggesting that some investors are positioning for a potential turnaround or are employing options strategies to capitalise on volatility.

Investor participation has notably increased, with delivery volumes rising to 2.89 crore shares on 12 March 2026, a 23.18% increase compared to the five-day average. This uptick in delivery volume indicates stronger conviction among buyers and sellers, despite the recent price decline. The stock’s liquidity remains robust, supporting trade sizes up to ₹74.54 crore based on 2% of the five-day average traded value, facilitating active participation from institutional and retail investors alike.

Fundamental and Market Positioning

HDFC Bank Ltd. remains a large-cap stalwart in the private sector banking industry with a market capitalisation of ₹12,81,247 crore. The company’s Mojo Score currently stands at 51.0, reflecting a Hold rating, an improvement from its previous Sell grade as of 27 February 2026. This upgrade indicates a stabilising outlook amid recent volatility, though the stock has yet to demonstrate a clear bullish reversal.

The divergence between the stock’s technical weakness and the surge in call option activity may reflect a nuanced market view. Some investors could be anticipating a near-term recovery driven by upcoming corporate developments or macroeconomic factors, while others might be employing options for hedging or speculative purposes. The expiry date of 30 March 2026 is critical, as it will reveal whether the bullish positioning materialises into upward price momentum.

Sector and Broader Market Comparison

In comparison to its sector peers, HDFC Bank’s one-day return of -1.59% slightly underperformed the private sector banking sector’s decline of -1.19% and the Sensex’s broader fall of -0.84%. This relative underperformance highlights the stock’s current vulnerability within an otherwise broadly negative market environment. However, the elevated call option volumes suggest that some investors view the current price levels as an attractive entry point for potential gains.

Given the stock’s recent three-day losing streak and the technical indicators signalling bearish momentum, investors should approach the call option activity with caution. The market’s mixed signals underscore the importance of monitoring price action closely in the coming days, especially as the expiry date approaches.

Investor Takeaways and Outlook

For investors tracking HDFC Bank, the current environment presents a complex scenario. The stock’s technical indicators and recent price lows suggest caution, while the surge in call option activity at the ₹840 strike price indicates that a segment of the market is positioning for a rebound. This dichotomy may reflect differing time horizons or risk appetites among market participants.

Given the stock’s liquidity and rising delivery volumes, active traders and institutional investors have ample opportunity to execute strategies around the upcoming expiry. However, the Hold rating and moderate Mojo Score imply that investors should weigh the risks carefully and consider broader market conditions before committing to bullish positions.

As expiry approaches on 30 March 2026, the resolution of these call options will provide clearer signals on market sentiment and potential price direction. Until then, monitoring open interest trends, volume spikes, and price action relative to key moving averages will be crucial for informed decision-making.

Summary

HDFC Bank Ltd. is currently navigating a challenging phase marked by a new 52-week low and technical weakness. Despite this, the stock has attracted significant call option interest at the ₹840 strike price, reflecting a cautious but optimistic segment of investors. The stock’s Hold rating and improved Mojo Grade from Sell to Hold suggest stabilisation, but the near-term outlook remains uncertain. Investors should remain vigilant and consider both technical and fundamental factors as expiry approaches.
