Strong Call Option Volumes Concentrated Near Current Price
Data from the derivatives market reveals that Reliance Industries (NSE: RELIANCE) recorded significant call option activity with the 29 September expiry contracts dominating turnover. The underlying stock closed at ₹1,319.90, with the most active call strikes clustered around ₹1,300 to ₹1,350. Notably, the 1,300 strike call saw the highest number of contracts traded at 12,196, generating a turnover of ₹2,001.97 lakhs and an open interest of 12,673 contracts. Close behind, the 1,320 strike call recorded 12,358 contracts traded with ₹1,436.62 lakhs turnover and an open interest of 13,250 contracts.
The 1,310 strike call also attracted substantial interest, with 7,852 contracts traded and turnover exceeding ₹1,118 lakhs. Meanwhile, the 1,350 strike call, slightly out-of-the-money relative to the current price, saw 7,456 contracts exchanged, contributing ₹442.89 lakhs in turnover and an open interest of 12,328 contracts. This concentration of activity near-the-money and slightly out-of-the-money strikes suggests traders are positioning for a potential upward move in Reliance’s share price before expiry.
Expiry Patterns and Open Interest Indicate Bullish Positioning
The open interest figures across these strikes further reinforce the bullish bias. The highest open interest at the 1,320 strike (13,250 contracts) indicates a strong build-up of long call positions, which typically benefit from price appreciation. The sizeable open interest at the 1,350 strike also points to speculative bets on a breakout above this level. Given the expiry date is less than a month away, these positions imply traders expect Reliance to breach or at least test these strike prices within this timeframe.
Such positioning is consistent with the stock’s recent performance, which has outperformed its sector by 0.35% on the day and delivered a 3.23% return over the past two sessions. The stock’s narrow trading range of ₹1.9 on the day and its trading above the 5-day, 20-day, and 50-day moving averages, albeit below the 100-day and 200-day averages, suggest a consolidation phase with potential for a breakout.
Mojo Score Downgrade Contrasts with Market Optimism
Despite the bullish options activity, Reliance’s Mojo Score currently stands at 47.0 with a Mojo Grade of Sell, downgraded from Hold on 11 May 2026. This downgrade reflects a cautious stance based on fundamental and technical assessments, signalling potential headwinds or valuation concerns. The large-cap oil sector stock, with a market capitalisation of ₹17,56,658 crores, faces challenges including fluctuating crude prices and regulatory pressures that may temper longer-term upside.
However, the short-term options market appears to be discounting these risks, with traders favouring call options at strikes close to the current price. This divergence between fundamental grading and derivatives positioning highlights the nuanced market sentiment where speculative and hedging activities coexist.
Liquidity and Investor Participation Metrics
Reliance remains a highly liquid stock, with a delivery volume of 80.85 lakh shares on 1 September 2026, though this represents an 18.45% decline against the five-day average delivery volume. The stock’s liquidity supports sizeable trade sizes, with an estimated Rs 38.31 crore capacity based on 2% of the five-day average traded value. This liquidity underpins the active options market, enabling large institutional and retail participants to execute sizeable positions efficiently.
Comparative Performance and Sector Context
On the day, Reliance’s stock gained 0.63%, outperforming the oil sector’s modest 0.07% rise and contrasting with the broader Sensex’s decline of 0.78%. This relative strength in a challenging market environment may be a factor driving the bullish options interest. Investors appear to be positioning for a rebound or sector rotation favouring integrated oil majors amid evolving energy demand dynamics.
Implications for Investors and Traders
The pronounced call option activity at strikes near the current market price suggests that traders are anticipating a positive price movement in Reliance Industries over the coming weeks. For investors, this could signal a tactical opportunity to monitor the stock for potential breakouts, especially as the expiry date approaches. However, the fundamental downgrade advises caution, underscoring the importance of balancing technical momentum with underlying business risks.
Traders utilising options strategies might consider the liquidity and open interest data to gauge market sentiment and potential price targets. The clustering of open interest at the 1,320 and 1,350 strikes could serve as key resistance levels to watch. Conversely, a failure to breach these levels might lead to profit-taking and a reversion to the mean.
Conclusion
Reliance Industries Ltd’s derivatives market activity ahead of the 29 September 2026 expiry reveals a strong bullish tilt among options traders, with significant call volumes and open interest concentrated at strikes just above the current share price. This optimism contrasts with a recent fundamental downgrade, reflecting a complex market outlook where short-term technical factors and speculative positioning diverge from longer-term caution. Investors and traders should carefully weigh these dynamics when considering exposure to this large-cap oil sector heavyweight in the weeks ahead.
