HDFC Bank Sees Heavy Put Option Activity Ahead of January Expiry

Put Option Activity Highlights

On 21 January 2026, HDFC Bank’s put options with a strike price of ₹920 emerged as the most actively traded contracts, with 3,899 contracts changing hands. The turnover for these put options reached ₹85.56 lakhs, reflecting significant investor interest in downside protection or speculative bearish bets. Open interest stood at 3,684 contracts, indicating sustained positions held by traders ahead of the expiry date on 27 January 2026.

The underlying stock price at the time was ₹925.55, just above the ₹920 strike, suggesting that investors are positioning for a potential dip below this level. This strike price is psychologically important, as it sits close to the current market price, making these puts attractive for hedging existing long positions or for directional bearish plays.

Price and Volume Context

HDFC Bank’s stock price movement on the day was modest, with a 0.64% gain, mirroring the sector’s performance which also rose by 0.64%. The Sensex outperformed slightly with a 0.96% increase. However, the stock traded within a narrow range of ₹5.7, reflecting subdued volatility. Notably, the stock is trading below all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — signalling a bearish technical setup.

Investor participation has declined, with delivery volume on 21 January falling by 29.87% compared to the five-day average, registering at 1.88 crore shares. Despite this, liquidity remains robust, with the stock’s traded value supporting a trade size of approximately ₹71.03 crore based on 2% of the five-day average traded value. This liquidity ensures that option and stock trades can be executed efficiently without significant price impact.

Mojo Score and Analyst Ratings

HDFC Bank currently holds a Mojo Score of 54.0, categorised as a 'Hold' rating, a downgrade from its previous 'Buy' grade as of 12 January 2026. This reflects a tempered outlook on the stock’s near-term prospects amid mixed technical and fundamental signals. The bank’s market capitalisation stands at a substantial ₹14,15,612 crore, underscoring its status as a large-cap heavyweight within the private sector banking industry.

The downgrade in Mojo Grade aligns with the technical weakness observed in the stock’s price action and the increased put option activity, suggesting that investors and analysts are cautious about further upside in the short term. The bank’s performance today was inline with its sector, but the technical indicators and option market data point to a more defensive stance.

Expiry Patterns and Investor Positioning

The expiry on 27 January 2026 is attracting significant attention, with the ₹920 put strike price being the focal point for bearish bets. The concentration of open interest near this strike suggests that traders are either hedging existing long positions or speculating on a downside move. The relatively high open interest combined with turnover indicates that these positions are not merely speculative but may represent genuine risk management strategies.

Given the stock’s current trading below all major moving averages and the decline in delivery volumes, the market sentiment appears cautious. Investors may be anticipating near-term volatility or a correction, prompting increased demand for downside protection through put options.

Sector and Market Comparison

Within the private sector banking space, HDFC Bank’s put option activity stands out as the most active, signalling a divergence from the broader sector’s modest gains. While the sector rose by 0.64%, the underlying technical weakness in HDFC Bank and the surge in bearish option positioning highlight a more nuanced market view. This contrasts with the Sensex’s stronger 0.96% gain, indicating that broader market optimism is not fully reflected in HDFC Bank’s near-term outlook.

Implications for Investors

For investors holding HDFC Bank shares, the heightened put option activity near the ₹920 strike price should be a signal to reassess risk exposure. The technical indicators and option market data suggest that downside risks are being actively hedged or anticipated. Investors may consider protective strategies such as buying puts or tightening stop-loss levels to mitigate potential losses.

Conversely, traders looking for opportunities might view the current put option volumes as a contrarian indicator, potentially signalling oversold conditions if the stock stabilises above key support levels. However, given the stock’s trading below all major moving averages and the recent downgrade in analyst sentiment, caution remains warranted.

Outlook and Conclusion

HDFC Bank’s recent surge in put option trading ahead of the 27 January expiry reflects a cautious and somewhat bearish market stance. While the stock’s price remains close to the ₹920 strike, the technical weakness and declining investor participation suggest that downside risks are being priced in. The downgrade from 'Buy' to 'Hold' by MarketsMOJO further underscores the tempered outlook.

Investors should closely monitor the stock’s price action relative to key moving averages and expiry dynamics in the options market. The liquidity and large market capitalisation of HDFC Bank ensure that it remains a key bellwether for the private sector banking sector, but near-term volatility and hedging activity warrant a prudent approach.

Overall, the combination of technical signals, option market positioning, and analyst sentiment points to a period of consolidation or mild correction for HDFC Bank, with the ₹920 strike price serving as a critical level to watch in the coming days.
