Bajaj Auto Sees Heavy Put Option Activity Ahead of December Expiry

Put Option Activity and Market Context

Data from the derivatives market reveals that Bajaj Auto Ltd. recorded 2,272 put option contracts traded for the expiry dated 30 December 2025, with a turnover of approximately ₹20.06 crores. The open interest stands at 2,210 contracts, indicating sustained interest in downside protection or speculative bearish bets. The underlying stock price at the time was ₹9,133, placing the ₹9,000 strike price slightly out-of-the-money but close enough to attract significant attention.

Such concentrated put option activity often reflects investor sentiment anticipating potential price corrections or seeking to hedge existing long positions. This is particularly noteworthy given Bajaj Auto’s proximity to its 52-week high of ₹9,490, being just 3.49% away. The stock’s recent performance shows a two-day consecutive gain, with a cumulative return of 1.63%, yet it underperformed its sector by 0.35% on the latest trading day.

Price and Volume Dynamics

Bajaj Auto’s price is currently trading above all key moving averages, including the 5-day, 20-day, 50-day, 100-day, and 200-day averages, which typically signals a bullish technical setup. However, investor participation appears to be moderating, as delivery volume on 28 November was 2.27 lakh shares, down by 17.79% compared to the five-day average delivery volume. This decline in delivery volume may suggest a cautious approach by investors despite the stock’s upward momentum.

Liquidity remains adequate for sizeable trades, with the stock’s average traded value over five days supporting trade sizes up to ₹8.97 crores based on 2% of the average value. This liquidity facilitates active options trading and allows market participants to implement complex strategies involving puts and calls without significant price impact.

Sector and Market Comparison

Within the automobile sector, Bajaj Auto’s one-day return of 0.69% trails the sector’s 1.41% gain and the Sensex’s 0.22% rise, indicating a relatively subdued performance on the day. The company’s market capitalisation stands at ₹2,55,143.71 crores, categorising it as a large-cap stock with significant weight in the sector.

Despite the stock’s strong technical positioning, the active put option interest suggests that market participants are either hedging against potential near-term volatility or positioning for a pullback. The strike price concentration at ₹9,000, close to the current market price, is a common level for protective puts, which can limit downside risk for holders of the underlying shares.

Expiry Patterns and Investor Behaviour

The December expiry is often a critical period for options traders, as it coincides with the end of the calendar year and can be influenced by broader macroeconomic factors, including policy announcements and global market trends. The clustering of put options at a single strike price for Bajaj Auto indicates a strategic focus on downside risk management or speculative positioning ahead of this expiry.

Open interest data supports this view, with 2,210 contracts outstanding, suggesting that these positions are not merely intraday trades but part of a broader tactical approach. Investors may be balancing their portfolios by acquiring puts to offset long exposure or speculating on a potential correction after recent gains.

Implications for Investors and Traders

For investors in Bajaj Auto, the active put option interest at the ₹9,000 strike price may serve as a cautionary signal to monitor the stock closely for any signs of reversal or increased volatility. Traders utilising options strategies might view this as an opportunity to implement protective hedges or to speculate on potential downside moves in the near term.

Given the stock’s current position near its 52-week high and its trading above all major moving averages, the market appears to be in a state of balance between bullish technical indicators and cautious sentiment expressed through options activity. This duality underscores the importance of a measured approach when considering exposure to Bajaj Auto in the current environment.

Broader Market Context

The automobile sector continues to attract investor interest amid evolving consumer demand and regulatory developments. Bajaj Auto, as a leading player, remains a focal point for market participants seeking exposure to two-wheeler and three-wheeler segments. The interplay between spot market performance and derivatives activity provides valuable insights into market expectations and risk management practices.

As the December expiry approaches, monitoring changes in open interest and volume across strike prices will be crucial to understanding shifts in market sentiment. The current concentration of put options at ₹9,000 for Bajaj Auto suggests that investors are positioning for potential downside protection while maintaining exposure to the stock’s longer-term prospects.

Conclusion

Bajaj Auto Ltd.’s prominence in the put options market ahead of the 30 December 2025 expiry highlights a nuanced market stance combining technical strength with prudent risk management. The substantial trading volume and open interest at the ₹9,000 strike price reflect investor strategies aimed at hedging or speculating on downside risk despite the stock’s proximity to its yearly highs.

Investors and traders should consider these dynamics carefully, balancing the stock’s technical indicators with the implications of heavy put option activity. This approach will help in navigating potential volatility and making informed decisions in the evolving market landscape.
