Reliance Industries Sees Heavy Call Option Activity Ahead of December Expiry

Call Option Activity Highlights

Data from the derivatives market reveals that Reliance Industries’ call options expiring on 30 December 2025 have witnessed substantial trading interest. The ₹1600 strike price call options recorded 2,609 contracts traded, generating a turnover of approximately ₹24.46 crores. Open interest at this strike stands at 10,085 contracts, indicating a strong build-up of positions ahead of the expiry date.

This level of activity suggests that investors are positioning themselves for potential upward price movements, as the underlying stock currently trades at ₹1572.7, just 0.5% shy of its 52-week high of ₹1581.3. The concentration of open interest near the current market price often signals expectations of a breakout or sustained strength in the underlying equity.

Price and Volume Dynamics

Reliance Industries has been trading within a narrow range of ₹7.8 in recent sessions, reflecting a period of consolidation. Despite this, the stock has recorded gains over the last two days, delivering a cumulative return of 0.65%. Its one-day return of 0.46% marginally outpaces the sector’s 0.39% and the Sensex’s 0.32%, underscoring relative strength within the oil sector.

Technical indicators further support this positive stance, with the stock trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Such positioning typically indicates a bullish trend across multiple timeframes, which may be encouraging traders to take call option positions in anticipation of further price appreciation.

However, investor participation as measured by delivery volume has shown a decline. On 28 November, delivery volume stood at 52.44 lakh shares, down by 36.41% compared to the five-day average. This reduction in delivery volume could imply that while short-term trading interest remains robust, longer-term commitment from investors is somewhat subdued.

Market Capitalisation and Liquidity Considerations

Reliance Industries commands a market capitalisation of ₹21,20,335 crore, categorising it firmly as a large-cap stock within the oil industry. Its liquidity profile supports sizeable trades, with the stock’s average traded value over five days allowing for trade sizes up to ₹42.77 crore based on 2% of the average volume. This liquidity ensures that option traders can enter and exit positions with relative ease, an important factor for active derivatives market participants.

Expiry Patterns and Strike Price Concentration

The December 2025 expiry is attracting the bulk of call option activity for Reliance Industries, with the ₹1600 strike price emerging as the focal point. This strike is slightly above the current market price, indicating that traders are speculating on a moderate upside in the coming weeks. The open interest accumulation at this strike suggests a consensus around this price level as a key threshold for the stock’s near-term trajectory.

Options traders often use such strike price concentrations to gauge market sentiment. The build-up of call options at ₹1600 could be interpreted as a hedge against potential price rises or as outright bullish bets. Given the stock’s recent performance and technical positioning, this activity aligns with a market view that Reliance Industries may test or surpass this level before expiry.

Sectoral Context and Comparative Performance

Within the oil sector, Reliance Industries continues to be a bellwether stock. Its performance today aligns closely with sector returns, reflecting broader industry trends. The stock’s ability to maintain a position near its 52-week high amid sectoral fluctuations highlights its relative resilience.

Comparing the stock’s one-day return of 0.46% with the Sensex’s 0.32% and the sector’s 0.39% suggests that Reliance Industries is maintaining a slight edge in market performance. This relative outperformance may be contributing to the heightened call option interest as traders seek to capitalise on the stock’s momentum within the oil industry framework.

Investor Sentiment and Outlook

The current call option activity around Reliance Industries reflects a cautiously optimistic market stance. While the stock’s proximity to its 52-week high and its position above key moving averages support a bullish outlook, the decline in delivery volumes signals some reservation among longer-term investors. This dichotomy suggests that while short-term traders are positioning for gains, institutional or retail holders may be adopting a wait-and-watch approach.

Given the stock’s liquidity and market capitalisation, Reliance Industries remains a preferred choice for derivatives trading within the oil sector. The concentration of call options at the ₹1600 strike price for the December expiry will be a key level to monitor, as it may indicate the market’s expectations for the stock’s near-term price direction.

As expiry approaches, shifts in open interest and trading volumes will provide further insight into investor sentiment and potential price movements. Market participants should continue to observe these metrics alongside broader sectoral and macroeconomic developments impacting the oil industry.

Conclusion

Reliance Industries is currently at the centre of significant call option activity, with the December 2025 expiry and ₹1600 strike price drawing the most attention. The stock’s technical positioning, relative performance, and liquidity profile underpin this interest, reflecting a market environment where traders are positioning for potential upside. However, the mixed signals from delivery volumes suggest a nuanced investor outlook, balancing optimism with caution.

Investors and traders alike should keep a close watch on evolving option open interest and price action as the expiry date nears, as these will provide valuable clues on the stock’s trajectory in the coming weeks.
