Open Interest and Volume Dynamics
On 31 Dec 2025, IOC’s open interest (OI) in derivatives rose sharply by 3,110 contracts, an 11.8% increase from the previous OI of 26,364 to 29,474. This substantial rise in OI is accompanied by a volume of 19,505 contracts, indicating robust trading activity. The futures value stood at ₹33,594.95 lakhs, while the options segment exhibited an enormous notional value of ₹12,647.41 crores, reflecting heightened speculative and hedging activity.
The total derivatives value traded was ₹35,567.84 lakhs, underscoring the liquidity and investor participation in IOC’s contracts. Such a surge in open interest, alongside strong volume, often points to fresh positions being established rather than existing ones being squared off, hinting at a directional conviction in the market.
Price Performance and Technical Indicators
IOC’s stock price closed at ₹166, just 4.6% shy of its 52-week high of ₹174.5, demonstrating resilience and strength. The stock outperformed its sector, the Oil Exploration and Refineries segment, which gained 2.28% on the day, with IOC itself rising 3.34%, outperforming the sector by 1.01% and the Sensex by 2.65 percentage points.
Intraday, the stock touched a high of ₹167, marking a 3.36% gain. Importantly, IOC is trading above all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — signalling a sustained uptrend and positive momentum. This technical backdrop supports the bullish interpretation of the open interest surge.
Investor Participation and Market Liquidity
Investor engagement has also intensified, with delivery volumes on 30 Dec reaching 59.94 lakh shares, a 25.01% increase over the five-day average delivery volume. This rise in delivery volume indicates genuine buying interest rather than short-term speculative trading.
Liquidity remains ample, with the stock’s average traded value supporting trade sizes up to ₹2.82 crore comfortably, making it attractive for institutional and retail investors alike. The high dividend yield of 4.95% further adds to the stock’s appeal, providing income alongside capital appreciation potential.

Market Positioning and Directional Bets
The increase in open interest alongside rising volumes and price appreciation suggests that market participants are positioning for further upside in IOC. The 11.8% jump in OI is significant in the context of the stock’s large-cap status and the oil sector’s recent strength.
Given the futures and options data, it appears that traders are establishing fresh long positions, possibly anticipating continued gains driven by favourable crude oil prices, refining margins, or government policy support. The stock’s mojo score of 74.0, with a current mojo grade of Buy (downgraded from Strong Buy on 29 Dec 2025), reflects a positive but slightly more cautious outlook, balancing strong fundamentals with near-term valuation considerations.
IOC’s market capitalisation stands at ₹2,30,600 crore, placing it firmly in the large-cap category with a market cap grade of 1, indicating high stability and investor confidence. The stock’s outperformance relative to the Sensex and sector benchmarks further validates the bullish sentiment.
Sectoral Context and Broader Market Trends
The Oil Exploration and Refining sector has gained 2.28% on the day, supported by rising crude oil prices and improving demand outlook. IOC’s outperformance within this sector highlights its leadership position and operational strengths. The stock’s ability to trade above all major moving averages signals robust technical health, which often attracts momentum traders and institutional buyers.
Moreover, the rising delivery volumes and high dividend yield of 4.95% make IOC an attractive proposition for both growth and income-focused investors. The stock’s liquidity profile supports sizeable trades, ensuring that large investors can enter or exit positions without significant price impact.

Outlook and Investor Considerations
While the recent surge in open interest and price momentum is encouraging, investors should remain mindful of broader market volatility and commodity price fluctuations that can impact IOC’s performance. The downgrade from Strong Buy to Buy in the mojo grade on 29 Dec 2025 suggests a tempered optimism, possibly reflecting valuation concerns or near-term risks.
Nonetheless, the company’s strong fundamentals, sector leadership, and attractive dividend yield provide a solid investment case. The technical indicators and derivatives market activity point towards sustained bullishness, making IOC a compelling stock for investors seeking exposure to India’s oil sector.
In summary, the sharp increase in open interest, combined with rising volumes and price gains, signals that market participants are positioning for further upside in Indian Oil Corporation Ltd. The stock’s strong market cap, liquidity, and dividend yield enhance its appeal amid a positive sectoral backdrop.
