HDFC Bank Sees Heavy Put Option Activity Ahead of December Expiry

Put Option Activity Highlights

Data from the derivatives market reveals that HDFC Bank’s put options with a strike price of ₹1000 have witnessed significant trading volume, with 2,651 contracts exchanged recently. The turnover for these contracts stands at approximately ₹16.39 crores, indicating substantial investor interest in downside protection or speculative bearish bets. Open interest for these puts is recorded at 6,412 contracts, underscoring sustained positioning ahead of the expiry date.

The underlying stock price is currently ₹995.7, just 2.49% shy of its 52-week high of ₹1020.5. This proximity to the peak price level juxtaposed with heavy put option activity suggests that market participants may be anticipating a potential correction or are seeking to hedge existing long positions amid recent volatility.

Price and Market Context

On the trading day under review, HDFC Bank’s stock price declined by 0.56%, slightly underperforming the sector’s 0.37% fall and the Sensex’s 0.49% drop. The stock has retraced after two consecutive days of gains, trading within a narrow range of ₹9.8, which points to a consolidation phase. Notably, the share price remains above its 50-day, 100-day, and 200-day moving averages, though it is positioned below the shorter-term 5-day and 20-day averages, indicating mixed momentum signals.

Investor participation has shown signs of strengthening, with delivery volume reaching 93.01 lakh shares on 12 December, a 5.14% rise compared to the five-day average delivery volume. This increase in delivery volume suggests that investors are actively taking or holding positions in the stock, which may be influencing option market dynamics.

Liquidity metrics also support active trading, with the stock’s average traded value over five days allowing for trade sizes up to ₹28.08 crores based on 2% of the average value. This level of liquidity facilitates the execution of sizeable option and equity trades without significant market impact.

Interpreting the Put Option Interest

Put options are commonly used either as a hedge against potential declines in the underlying stock or as a speculative instrument to profit from anticipated downward moves. The concentration of put contracts at the ₹1000 strike price, which is near the current market price, indicates that investors are positioning for a possible dip below this level before the December expiry.

Given the stock’s recent trading pattern—hovering near its yearly high but showing signs of short-term weakness—this put option activity could reflect a cautious stance. Market participants might be protecting gains accumulated during the recent rally or preparing for volatility around the expiry period.

Sector and Market Comparison

HDFC Bank operates within the private sector banking industry, a segment that has shown resilience but also faces challenges from macroeconomic factors and regulatory developments. The stock’s performance today aligns closely with its sector peers, which collectively experienced a modest decline. The broader Sensex index also registered a similar downward movement, suggesting that the put option interest may be influenced by wider market sentiment rather than company-specific news alone.

With a market capitalisation of approximately ₹15.39 lakh crores, HDFC Bank is classified as a large-cap stock, attracting significant institutional and retail investor attention. Its liquidity and trading volumes support active derivatives market participation, making it a focal point for option traders seeking to manage risk or capitalise on directional views.

Technical Indicators and Moving Averages

The stock’s position relative to key moving averages offers a nuanced picture. While it remains above the longer-term 50-day, 100-day, and 200-day averages—often interpreted as a bullish sign—the dip below the 5-day and 20-day averages signals short-term pressure. This divergence may be contributing to the increased put option activity as traders weigh the possibility of a near-term pullback.

Such technical signals often prompt investors to adopt protective strategies, including buying puts or selling calls, to mitigate downside risk. The open interest data corroborates this, showing a build-up of positions that could be unwound or exercised depending on price movements in the coming weeks.

Expiry Patterns and Investor Behaviour

The December 30 expiry date is a critical juncture for options traders, as positions are squared off or rolled forward. The concentration of put options at the ₹1000 strike price suggests that investors are actively managing their exposure ahead of this deadline. This behaviour is typical in large-cap stocks with liquid options markets, where hedging and speculative strategies intensify near expiry.

Investors holding long positions in HDFC Bank may be utilising these puts as insurance against a price decline, while others might be speculating on a correction given the stock’s recent short-term pullback. The interplay of these forces contributes to the elevated open interest and turnover observed in the put segment.

Outlook and Considerations for Investors

While the put option activity points to a degree of caution, it is important to consider the broader context. HDFC Bank’s fundamentals remain robust, supported by its large market capitalisation and steady investor participation. The stock’s proximity to its 52-week high indicates underlying strength, even as short-term technical indicators suggest some volatility.

Investors and traders should monitor price movements closely in the coming days, particularly around the ₹1000 level, which appears to be a key psychological and technical threshold. The expiry on 30 December will likely bring clarity on market sentiment and positioning, as option contracts are settled or rolled over.

Overall, the current derivatives market data for HDFC Bank provides valuable insight into investor expectations and risk management strategies, highlighting the dynamic interplay between equity and options markets in shaping stock price behaviour.
