Reliance Industries Sees Robust Call Option Activity Ahead of December Expiry

Call Option Activity Highlights

On the derivatives front, Reliance Industries Ltd recorded a significant volume of call option contracts with 7,519 contracts traded for the 30 December 2025 expiry at the ₹1600 strike price. This activity generated a turnover of approximately ₹289.48 lakhs, underscoring strong investor interest in bullish positioning. Open interest at this strike stands at 19,205 contracts, indicating a substantial build-up of outstanding positions that could influence price movements as expiry approaches.

The underlying stock price at ₹1557.20 is currently trading just 1.64% below its 52-week high of ₹1581.30, suggesting that the ₹1600 strike is a key psychological and technical level for traders. The proximity to this strike price may be encouraging market participants to take call positions in anticipation of a potential upward move in the near term.

Price and Market Context

Reliance Industries’ stock price has shown resilience, outperforming its sector by 0.34% on the day, with a 1.18% return compared to the sector’s 0.76% and the Sensex’s 0.41%. This outperformance follows a trend reversal after three consecutive days of decline, signalling renewed buying interest. The stock is trading above its 20-day, 50-day, 100-day, and 200-day moving averages, although it remains below the 5-day moving average, indicating some short-term consolidation.

Liquidity remains adequate for sizeable trades, with the stock’s traded value supporting a trade size of approximately ₹29.61 crores based on 2% of the five-day average traded value. However, delivery volumes have shown a decline, with 43.45 lakh shares delivered on 3 December representing a 33.11% drop against the five-day average delivery volume. This suggests a cautious stance among long-term investors despite active trading in the options market.

Sector and Market Capitalisation Overview

Reliance Industries operates within the oil sector, a segment that continues to attract significant investor attention due to global energy demand dynamics and evolving geopolitical factors. The company’s market capitalisation stands at a substantial ₹20,91,984 crores, categorising it firmly as a large-cap stock. This scale provides it with considerable influence on sectoral indices and investor portfolios alike.

Given the oil sector’s sensitivity to crude price fluctuations and regulatory developments, the active call option interest in Reliance Industries may reflect market participants’ anticipation of favourable developments or a strategic hedge against sector volatility. The stock’s recent price behaviour, combined with its technical positioning above key moving averages, supports a cautiously optimistic outlook among traders.

Expiry Patterns and Strike Price Significance

The 30 December 2025 expiry date is attracting the highest call option volumes for Reliance Industries, with the ₹1600 strike price serving as a focal point. This strike is slightly above the current underlying price, indicating that traders are positioning for a potential price appreciation beyond this level before the end of the year. The open interest data corroborates this, showing a concentration of outstanding contracts at this strike, which could lead to increased price sensitivity as expiry nears.

Such expiry patterns often reveal market sentiment and expectations. The clustering of call options at a near-the-money strike price suggests that investors are balancing between bullish bets and risk management, possibly anticipating catalysts such as quarterly results, policy announcements, or sectoral developments that could influence the stock’s trajectory.

Investor Positioning and Market Implications

The active call option trading in Reliance Industries reflects a market environment where investors are seeking exposure to potential upside while managing risk through defined strike prices and expiry timelines. The concentration of contracts at ₹1600 suggests a consensus around this level as a key resistance or target zone in the near term.

While the underlying stock price remains below the 5-day moving average, its position above longer-term averages indicates a generally positive trend. The recent outperformance relative to the sector and benchmark indices further supports the notion that Reliance Industries is attracting focused attention from traders and investors alike.

However, the decline in delivery volumes signals a degree of caution among long-term holders, possibly reflecting profit-booking or a wait-and-watch approach ahead of upcoming market events. This divergence between derivatives activity and delivery participation highlights the nuanced market dynamics at play.

Outlook and Considerations

As the 30 December expiry approaches, monitoring the open interest and volume trends in Reliance Industries’ call options will be crucial for gauging market sentiment and potential price movements. The stock’s proximity to its 52-week high and its technical positioning suggest that any sustained move above the ₹1600 strike could trigger further momentum.

Investors and traders should also consider broader sectoral factors, including crude oil price trends, regulatory developments, and global economic conditions, which may impact Reliance Industries’ performance and, by extension, its options market activity.

Overall, the current derivatives market data points to a cautiously optimistic stance on Reliance Industries, with significant interest concentrated in call options at a strategically important strike price and expiry date.
