Reliance Industries, a major player in the oil sector, has attracted significant attention in the derivatives market with a surge in call option trading ahead of the 30 December 2025 expiry. The stock’s underlying value and option activity suggest a notable positioning by investors, reflecting market sentiment and expectations for the coming weeks.



Call Option Activity Highlights


Reliance Industries Ltd has emerged as the most active stock in call options, with the December 30 expiry contracts drawing considerable volume. The strike price of ₹1,600 has seen 6,296 contracts traded, generating a turnover of approximately ₹39.32 crores. Open interest at this strike stands at 15,985 contracts, indicating sustained interest and potential positioning by market participants.


The underlying stock price at the time of this activity was ₹1,551.40, placing the ₹1,600 strike price slightly out of the money. This suggests that traders are anticipating a possible upward movement in the stock price before the expiry date, or are hedging existing positions with a bullish bias.



Stock Price and Market Context


Reliance Industries is trading close to its 52-week high, currently just 1.92% below the peak of ₹1,581.30. Despite this proximity to the high, the stock has experienced a modest decline over the past two days, with a cumulative fall of 1.02%. Today’s performance shows a 0.90% drop, underperforming both its sector, which declined by 0.59%, and the broader Sensex index, which fell by 0.40%.


Technical indicators reveal that the stock price remains above its 20-day, 50-day, 100-day, and 200-day moving averages, signalling a longer-term upward trend. However, it is currently trading below its 5-day moving average, reflecting short-term consolidation or profit-taking.


Investor participation appears to be waning, with delivery volume on 1 December recorded at 50.18 lakh shares, down by 38.68% compared to the five-day average. This decline in delivery volume may indicate reduced conviction among investors or a wait-and-watch approach ahead of key market events.



Liquidity and Market Capitalisation


Reliance Industries is classified as a large-cap stock with a market capitalisation of ₹21,08,765 crore, underscoring its dominant position in the oil sector. The stock’s liquidity supports sizeable trades, with the average traded value over five days sufficient to accommodate trade sizes of up to ₹37 crore based on 2% of the average value.


This liquidity profile is crucial for options traders, as it ensures that positions can be entered and exited with relative ease, reducing the risk of slippage and enabling more precise risk management.

Investor Positioning and Expiry Patterns


The concentration of call option contracts at the ₹1,600 strike price for the 30 December expiry suggests a strategic positioning by investors. This strike price is approximately 3% above the current underlying value, indicating a moderately bullish outlook for the stock over the next month.


Open interest levels at this strike price are significant, reflecting both fresh buying interest and possible rollovers from previous expiries. Such activity often precedes important corporate announcements, sectoral developments, or macroeconomic events that could influence the stock’s trajectory.


Options traders may be using these contracts to capitalise on expected volatility or to hedge existing equity holdings. The relatively high turnover and open interest also point to active market-making and liquidity provision in the options segment for Reliance Industries.



Sectoral and Market Comparison


Within the oil sector, Reliance Industries remains a key bellwether, with its stock performance closely watched by investors and analysts alike. The sector’s 1-day return of -0.59% contrasts with Reliance’s slightly larger decline of 0.90%, highlighting some relative weakness in the stock amid broader market pressures.


However, the stock’s position near its 52-week high and its standing above major moving averages suggest underlying resilience. This duality may explain the active call option interest, as market participants weigh the potential for a rebound against short-term headwinds.

Outlook and Considerations for Investors


Reliance Industries’ active call option market activity ahead of the December expiry provides insight into investor expectations and market dynamics. The strike price concentration and open interest levels suggest a cautiously optimistic stance, with traders positioning for potential upside while managing risk.


Investors should consider the broader market environment, including sectoral trends and macroeconomic factors, when analysing this options activity. The stock’s recent short-term underperformance relative to the sector and index may reflect profit-taking or uncertainty, but the longer-term technical indicators remain supportive.


Liquidity and market capitalisation further enhance the stock’s appeal for derivatives trading, enabling efficient execution of strategies. Monitoring changes in open interest and volume in the coming days will be crucial to gauge shifts in market sentiment as the expiry date approaches.



Summary


Reliance Industries continues to command significant attention in the options market, with the December 30 call options at ₹1,600 strike price showing robust trading volumes and open interest. The stock’s proximity to its 52-week high, combined with mixed short-term price action and strong liquidity, paints a nuanced picture of investor sentiment.


Market participants appear to be positioning for potential gains while remaining mindful of near-term volatility. This activity underscores Reliance Industries’ role as a key stock within the oil sector and the broader Indian equity market.
