Reliance Industries Sees Robust Call Option Activity Amid Narrow Trading Range

Call Option Activity Highlights

Reliance Industries Ltd, a major player in the oil sector with a market capitalisation exceeding ₹20 lakh crores, has witnessed substantial call option activity for contracts expiring on 30 December 2025. The most actively traded call options are concentrated at strike prices of ₹1,600 and ₹1,550, signalling investor focus on these levels as potential price targets or hedging points.

At the ₹1,600 strike price, 3,070 contracts were traded, generating a turnover of approximately ₹73.83 lakhs. The open interest at this strike stands at 20,360 contracts, indicating a significant build-up of positions. Meanwhile, the ₹1,550 strike price saw even higher trading volume with 3,322 contracts exchanged, accompanied by a turnover of ₹292.17 lakhs and an open interest of 6,848 contracts. These figures suggest a strong bullish positioning among market participants, anticipating potential upward price movement or seeking to capitalise on volatility near these levels.

Price Performance and Market Context

Reliance Industries closed at ₹1,524.6, which is approximately 3.92% below its 52-week high of ₹1,581.3. The stock has experienced a five-day consecutive decline, cumulatively returning -2.92% over this period. Despite this short-term downward trend, the stock remains above its 50-day, 100-day, and 200-day moving averages, reflecting underlying medium- to long-term support. However, it is trading below its 5-day and 20-day moving averages, indicating some near-term pressure.

The stock’s trading range has been relatively narrow, confined to about ₹10.5, which may suggest consolidation ahead of a directional move. Investor participation has shown signs of strengthening, with delivery volumes reaching 80.49 lakh shares on 4 December, marking a 43.83% increase compared to the five-day average delivery volume. This rise in delivery volume points to growing conviction among investors despite recent price softness.

Sector and Benchmark Comparison

In comparison to its sector peers, Reliance Industries underperformed marginally, with a one-day return of -0.76% against the oil sector’s -0.49%. The broader Sensex index posted a slight positive return of 0.04% on the same day. This relative performance highlights the stock’s sensitivity to sector-specific factors and broader market dynamics, which investors should monitor closely.

Implications of Open Interest and Strike Price Concentration

The concentration of open interest at the ₹1,600 strike price, which is above the current underlying price, suggests that traders are positioning for a potential upward move by the end of December. The sizeable open interest at this strike also implies that a significant number of contracts remain outstanding, which could influence price dynamics as expiry approaches.

Similarly, the high turnover and contract volume at the ₹1,550 strike price, closer to the current market price, indicate active trading and hedging activity. This strike price may be viewed as a critical support or resistance level by market participants, with the option activity reflecting expectations of price movement within this range.

Expiry Patterns and Market Sentiment

Options expiring on 30 December 2025 are attracting the bulk of trading interest, which is typical as expiry dates near and traders adjust their positions. The predominance of call options in the most active contracts points to a generally bullish sentiment or hedging against potential upside in Reliance Industries’ stock price.

Given the stock’s proximity to its 52-week high and the recent rise in delivery volumes, the market appears to be balancing between cautious optimism and short-term consolidation. Investors and traders may be awaiting fresh catalysts or broader market cues before committing to directional bets.

Liquidity and Trading Considerations

Reliance Industries exhibits sufficient liquidity to support sizeable trades, with the stock’s traded value comfortably accommodating trade sizes up to ₹31 crore based on 2% of the five-day average traded value. This liquidity profile is favourable for institutional investors and traders seeking to enter or exit positions without significant market impact.

The stock’s large-cap status and dominant position in the oil sector further enhance its appeal as a core holding or trading candidate within diversified portfolios. However, the recent short-term price softness and narrow trading range suggest that investors should monitor technical indicators and market developments closely before making significant commitments.

Outlook and Investor Takeaways

While Reliance Industries has experienced a modest pullback over the past week, the sustained call option activity at key strike prices and rising delivery volumes indicate ongoing investor interest and potential for renewed momentum. The stock’s position relative to moving averages and its proximity to the 52-week high provide a mixed technical picture, underscoring the importance of cautious analysis.

Investors may consider the option market data as a supplementary tool to gauge market sentiment and potential price levels of interest. The concentration of open interest and turnover at strikes above and near the current price suggests that market participants are positioning for possible upside scenarios while managing risk.

Overall, Reliance Industries remains a focal point within the oil sector, with its derivatives activity offering valuable insights into market expectations and positioning ahead of the December expiry.
