HDFC Bank Sees Heavy Put Option Activity Amid Bearish Sentiment Ahead of March Expiry

Put Option Activity Highlights

Data from the derivatives market reveals that put options with strike prices of ₹830 and ₹840 have been the most actively traded contracts for HDFC Bank Ltd. The ₹840 strike put option recorded 2,917 contracts traded, generating a turnover of ₹218.03 lakhs, while the ₹830 strike saw 2,116 contracts traded with a turnover of ₹108.58 lakhs. Open interest for these strikes stands at 3,249 and 2,508 contracts respectively, indicating substantial investor interest in downside protection or speculative bearish bets.

The underlying stock price closed at ₹836.15 on 18 March 2026, hovering just above the ₹830 strike but below the ₹840 strike, which suggests that traders are positioning for a potential decline or increased volatility in the coming weeks. The expiry date of 30 March 2026 is less than two weeks away, intensifying the focus on these strikes as key levels for market participants.

Price and Trend Analysis

HDFC Bank’s stock price is currently trading close to its 52-week low, just 2.91% above the ₹812 mark. The stock underperformed its sector by 0.69% on the day, declining 1.01% compared to the sector’s 0.38% fall and contrasting with the Sensex’s 0.56% gain. This divergence highlights the bank’s relative weakness amid broader market resilience.

Technical indicators show a mixed picture. The stock remains above its 5-day moving average but below its 20-day, 50-day, 100-day, and 200-day moving averages, signalling a potential short-term consolidation or correction phase within a longer-term downtrend. Investor participation has also waned, with delivery volume on 17 March falling by 27.49% against the five-day average, suggesting reduced conviction among buyers.

Mojo Score and Market Capitalisation

HDFC Bank holds a Mojo Score of 51.0 and a Mojo Grade of Hold as of 27 February 2026, upgraded from Sell. This reflects a cautious stance by MarketsMOJO analysts, recognising the bank’s large-cap status with a market capitalisation of ₹13,01,793 crores but acknowledging near-term headwinds. The Hold rating suggests that while the stock is not an outright sell, investors should monitor developments closely before committing fresh capital.

Investor Sentiment and Hedging Strategies

The surge in put option volumes at strike prices near the current market level indicates that investors are either hedging existing long positions or speculating on a downside move. The ₹840 strike, in particular, has attracted the highest open interest and turnover, suggesting it is a critical level for market participants to watch.

Given the stock’s proximity to its 52-week low and recent price weakness, the increased put buying could be a defensive measure against further declines. Alternatively, it may reflect bearish sentiment anticipating a correction in the private banking sector or broader market volatility ahead of the March expiry.

Sector and Market Context

Within the private sector banking space, HDFC Bank’s underperformance relative to its peers and the broader Sensex is notable. While the Sensex gained 0.56% on the day, HDFC Bank declined by 1.01%, signalling sector rotation or selective profit-taking. The bank’s liquidity remains robust, with a traded value sufficient to support sizeable transactions up to ₹75.98 crores, ensuring that option market activity is backed by adequate underlying stock liquidity.

Investors should also consider the broader macroeconomic environment, including interest rate trends and credit growth prospects, which can influence banking sector valuations and risk appetite.

Implications for Investors

For investors holding HDFC Bank shares, the heightened put option activity signals a need for caution. The current market dynamics suggest that downside risks are being actively priced in, and the stock may face pressure near-term. Those seeking to hedge their exposure might consider put options at or near the ₹830-₹840 strikes to mitigate potential losses.

Conversely, value investors may view the recent price weakness and the Hold rating as an opportunity to accumulate shares at attractive levels, provided they are comfortable with the prevailing volatility and sector outlook. Monitoring open interest trends and expiry patterns will be crucial in gauging market sentiment as the 30 March expiry approaches.

Conclusion

HDFC Bank Ltd.’s options market activity ahead of the March expiry reveals a clear tilt towards bearish positioning, with significant put option volumes concentrated at strikes just below and above the current stock price. While the bank’s upgraded Mojo Grade to Hold reflects some improvement in fundamentals, the technical and derivatives data underscore investor caution amid a challenging market environment.

Market participants should closely watch price movements, open interest changes, and sector developments to navigate the evolving risk landscape effectively. The interplay between hedging demand and speculative positioning in the options market will likely continue to influence HDFC Bank’s near-term price trajectory.
