Tata Motors Passenger Vehicles Sees Heavy Put Option Activity Ahead of December Expiry

Put Option Activity Highlights

Data from the derivatives segment reveals that Tata Motors Passenger Vehicles (TMPV) has attracted substantial put option interest, particularly for contracts expiring on 30 December 2025. The most actively traded put options cluster around strike prices of ₹360, ₹350, ₹340, and ₹330, with the underlying stock price currently at ₹360.45.

The highest volume of contracts traded is at the ₹350 strike, with 2,768 contracts exchanged, generating a turnover of approximately ₹132.64 lakhs and an open interest of 4,405 contracts. Close behind, the ₹360 strike put options saw 2,462 contracts traded, with turnover reaching ₹193.81 lakhs and open interest standing at 5,115 contracts. The ₹340 and ₹330 strikes also recorded significant activity, with 1,912 and 1,970 contracts traded respectively, and open interest levels of 3,258 and 2,307 contracts.

This concentration of put option activity at and slightly below the current market price suggests that market participants are positioning for potential downside risk or are seeking protection against adverse price movements in the near term. The open interest figures indicate that these positions are not merely speculative but may represent hedging strategies or bearish bets on the stock’s trajectory.

Stock Performance and Market Context

On the trading day preceding the expiry data, Tata Motors Passenger Vehicles recorded a 1.96% gain, outperforming its sector by 1.73%. The stock touched an intraday high of ₹362.85, marking a 2.95% rise. Despite this short-term strength, the stock remains below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating that the broader trend may still be under pressure.

Investor participation has shown signs of moderation, with delivery volumes on 25 November at 84.37 lakhs, down by 4.93% compared to the five-day average. Liquidity remains adequate, with the stock’s traded value supporting trade sizes of up to ₹10.63 crores based on 2% of the five-day average traded value.

Implications of Put Option Concentration

The clustering of put options at strike prices near the current market value of Tata Motors Passenger Vehicles suggests a cautious stance among traders. The ₹360 and ₹350 strikes, in particular, indicate that investors may be hedging against a potential decline or are speculating on a price correction before the December expiry.

Open interest levels at these strikes are substantial, with over 9,500 contracts combined at ₹350 and ₹360 strikes alone. This volume points to a significant pool of capital allocated to downside protection or bearish positioning. The presence of active put option trading at ₹340 and ₹330 strikes further extends the range of potential downside scenarios being considered by market participants.

Such activity often precedes periods of heightened volatility, as option holders may adjust or unwind positions in response to price movements or news flow. The expiry date of 30 December 2025 is a key milestone, as it will determine the realisation of these option positions and could influence the stock’s price dynamics in the short term.

Sector and Market Comparison

Within the broader automobile sector, Tata Motors Passenger Vehicles has shown relative strength on the day, with a 2.40% return compared to the sector’s 0.61% and the Sensex’s 0.47%. However, the stock’s positioning below all major moving averages suggests that the recent gains may be part of a corrective bounce rather than a sustained uptrend.

The company’s market capitalisation stands at ₹1,29,784 crores, classifying it as a large-cap stock with significant institutional interest. This scale often attracts complex option strategies, including hedging by mutual funds, insurance companies, and other large investors seeking to manage portfolio risk.

Investor Considerations and Outlook

For investors and traders, the heavy put option activity in Tata Motors Passenger Vehicles warrants close monitoring. The strike prices with the highest open interest and turnover provide insight into the levels at which market participants expect or seek protection against declines.

Given the stock’s current trading below key moving averages and the mixed signals from recent price action, the options market data may reflect a prudent approach to risk management. Investors should consider the broader market environment, sector trends, and company-specific developments when interpreting these signals.

Additionally, the liquidity profile of the stock supports active trading and the execution of complex option strategies, which may contribute to increased volatility as the expiry date approaches.

Summary

Tata Motors Passenger Vehicles is currently a focal point for put option activity, with significant contracts traded at strike prices near the current market value ahead of the 30 December 2025 expiry. This pattern suggests a degree of bearish positioning or hedging among market participants, despite the stock’s recent outperformance relative to its sector. The interplay between option market dynamics and the stock’s price action will be critical to watch in the coming weeks as investors navigate potential volatility and reassess risk exposure.
