Surge in Put Option Volumes and Open Interest
Data from the derivatives market reveals that Reliance Industries (NSE: RELIANCE) has recorded exceptionally high volumes in put options expiring on 29 September 2026. The most actively traded strike prices are clustered around ₹1,250 to ₹1,300, close to the stock’s current underlying value of ₹1,297.6. Notably, the 1300 strike put option saw 4,515 contracts traded, generating a turnover of ₹5.42 crores and an open interest of 12,358 contracts. This is the highest among the put strikes, indicating a strong interest in downside protection or speculative bearish bets at this level.
Other significant strikes include the 1280 put with 3,268 contracts traded and ₹2.50 crores turnover, and the 1290 put with 2,561 contracts traded and ₹2.41 crores turnover. The 1250 strike, which is just 3.42% above the stock’s 52-week low of ₹1,249.8, also attracted 2,546 contracts with ₹0.87 crores turnover. The open interest figures at these strikes—5,586 at 1280 and 3,489 at 1290—further underscore the concentration of bearish positioning near the current price.
Technical Context and Market Sentiment
Reliance Industries has been trading below all major moving averages, including the 5-day, 20-day, 50-day, 100-day, and 200-day averages, signalling sustained technical weakness. Despite outperforming its sector by 0.58% on the day, the stock remains close to its 52-week low, just 3.42% away, which may be prompting investors to hedge their exposure or position for further downside.
Investor participation has notably increased, with delivery volumes on 31 August reaching 3.05 crore shares—a staggering 531.45% rise compared to the five-day average delivery volume. This heightened activity suggests that market participants are actively adjusting their positions amid uncertain near-term prospects.
Implications of Put Option Activity
The concentration of put option trades at strike prices slightly below and above the current market price is indicative of a cautious or bearish outlook. Investors may be using these puts as insurance against a potential decline in Reliance’s share price or as outright speculative bets anticipating a correction. The large open interest at the 1300 strike, in particular, suggests that many traders expect the stock to test or breach this level before expiry.
Given Reliance’s market capitalisation of ₹17,38,931 crore and its classification as a large-cap stock, such option activity is significant. It reflects a broader market sentiment that is wary of near-term risks in the oil sector, where Reliance operates, amid fluctuating commodity prices and global economic uncertainties.
Comparative Performance and Sectoral Context
On the day under review, Reliance delivered a 1.75% gain, outperforming the oil sector’s 0.62% rise and the broader Sensex, which declined by 0.16%. Despite this relative strength, the persistent put buying suggests that investors remain cautious about sustaining gains. The narrow trading range of just ₹1 on the day further emphasises a lack of conviction among buyers, reinforcing the notion of a consolidating or weakening trend.
Outlook and Investor Considerations
With the 29 September expiry approaching, market participants should closely monitor the evolution of open interest and volume in Reliance’s put options. A sustained increase in put buying or open interest could signal growing bearish sentiment or hedging activity, potentially foreshadowing a correction or increased volatility. Conversely, a decline in put open interest might indicate easing concerns and a possible stabilisation of the stock price.
Investors should also consider Reliance’s recent downgrade from a Hold to a Sell rating on 11 May 2026, reflected in its Mojo Score of 47.0, which aligns with the cautious tone seen in the options market. The downgrade and the stock’s technical positioning suggest that downside risks remain material in the near term.
Conclusion
The heavy put option activity in Reliance Industries ahead of the September expiry highlights a market environment characterised by caution and defensive positioning. While the stock has shown some resilience relative to its sector and the broader market, the clustering of put trades near current price levels and the elevated open interest point to a significant contingent of investors preparing for potential downside or volatility. This dynamic warrants close attention from traders and portfolio managers seeking to navigate the evolving risk landscape in one of India’s largest oil sector companies.
