Surge in Put Option Volumes at Key Strike Prices
Data from the derivatives market reveals that Reliance Industries (NSE: RELIANCE) witnessed substantial put option activity clustered around strike prices of ₹1300, ₹1310, and ₹1320, all expiring on 25 August 2026. The highest number of contracts traded was at the ₹1310 strike, with 6,051 contracts exchanged, generating a turnover of approximately ₹246.28 lakhs. Close behind was the ₹1300 strike with 5,609 contracts traded and a turnover of ₹147.24 lakhs, while the ₹1320 strike saw 4,571 contracts traded, contributing ₹276.32 lakhs in turnover.
Open interest figures further underscore the concentration of bearish bets at the ₹1300 strike, which holds an open interest of 9,240 contracts, significantly higher than the 5,190 and 3,603 contracts open at the ₹1310 and ₹1320 strikes respectively. This clustering near the current underlying value of ₹1323.6 suggests investors are positioning for a potential downside move or are actively hedging existing long exposures.
Contextualising the Put Activity with Stock Performance
Reliance Industries has recorded a 0.84% gain on the day, outperforming the oil sector’s 0.67% rise and the broader Sensex’s decline of 0.21%. The stock has been on a two-day consecutive gain streak, delivering a cumulative return of 1.18% over this period. Despite this, the narrow trading range of ₹1.4 and the stock’s position above its 5-day, 20-day, and 50-day moving averages—but below its 100-day and 200-day averages—indicate a mixed technical picture.
Investor participation has notably increased, with delivery volumes on 17 August reaching 91.92 lakh shares, a 57.05% rise compared to the five-day average. Liquidity remains robust, supporting trade sizes up to ₹28.54 crores based on 2% of the five-day average traded value. This environment of heightened activity and liquidity provides fertile ground for options traders to express nuanced views on the stock’s near-term trajectory.
Bearish Positioning or Strategic Hedging?
The pronounced put option interest at strike prices slightly below the current market price suggests a cautious stance among market participants. Investors may be seeking downside protection amid uncertainties in the oil sector or broader macroeconomic concerns. The recent downgrade of Reliance’s Mojo Grade from Hold to Sell on 11 May 2026, with a current Mojo Score of 47.0, may also be influencing sentiment, prompting some to hedge long positions or speculate on a pullback.
Given Reliance’s status as a large-cap heavyweight with a market capitalisation of ₹17,84,129 crores, such concentrated put activity is significant. It reflects a strategic approach by institutional and retail investors alike to manage risk or capitalise on potential volatility ahead of the expiry date.
Expiry Patterns and Market Implications
The expiry on 25 August 2026 is attracting considerable attention, with put options dominating the most active contracts for Reliance. This pattern often precedes periods of increased volatility as traders adjust positions or close out contracts. The clustering of open interest near the ₹1300 strike price may act as a psychological support level, with market participants closely watching price action around this threshold in the coming sessions.
Should the stock breach this level decisively, it could trigger further downside momentum, validating the bearish bets. Conversely, a rebound above the current underlying value could see put option premiums decline, potentially leading to unwinding of these positions.
Comparative Sector and Market Overview
Within the oil sector, Reliance’s put option activity stands out, contrasting with more muted derivatives interest in peer stocks. The sector’s steady performance today, coupled with Reliance’s relative outperformance, suggests that the put buying is not purely speculative but may be driven by hedging strategies amid sector-specific or company-specific risks.
Investors should also consider the broader market context, where the Sensex’s slight decline contrasts with Reliance’s gains, highlighting the stock’s defensive appeal or idiosyncratic factors influencing its derivatives market.
Outlook for Investors and Traders
For investors, the heavy put option activity signals caution. Those holding Reliance shares might consider protective strategies such as buying puts or employing collars to mitigate downside risk. Traders could view the elevated open interest and turnover as an opportunity to capitalise on expected volatility, employing strategies that benefit from price swings or time decay in options premiums.
Monitoring the stock’s price relative to the key strike prices and expiry date will be crucial in the coming days. The interplay between spot price movements and options market positioning will provide valuable insights into market sentiment and potential directional shifts.
Summary
Reliance Industries Ltd’s derivatives market activity ahead of the 25 August 2026 expiry reveals a pronounced tilt towards put options, particularly at strike prices near ₹1300 to ₹1320. This suggests a cautious or bearish outlook among investors despite the stock’s recent gains and sector-aligned performance. The combination of increased delivery volumes, robust liquidity, and a recent downgrade in Mojo Grade underscores a complex risk-reward environment. Market participants should closely watch price action around these strike levels and expiry dynamics to inform their investment and trading decisions.
