Open Interest and Volume Dynamics
On 19 Feb 2026, ONGC's open interest in derivatives rose sharply to 1,35,516 contracts from the previous 1,21,795, marking an increase of 13,721 contracts or 11.27%. This expansion in OI is accompanied by a futures volume of 86,265 contracts, reflecting heightened trading activity. The futures value stood at ₹96,996.55 lakhs, while the options segment exhibited an enormous notional value of ₹42,899.63 crores, culminating in a total derivatives value of approximately ₹1,00,263.71 lakhs.
Such a surge in open interest alongside strong volume typically indicates fresh positions being initiated rather than existing ones being squared off. This is a key signal that market participants are actively positioning for a directional move, often interpreted as a bullish stance when aligned with price appreciation.
Price Action and Technical Context
ONGC's underlying stock price closed at ₹270, just 3.7% shy of its 52-week high of ₹280.3. The stock outperformed its sector by 2.86% on the day, registering a gain of 2.12% compared to the sector's decline of 0.69% and the Sensex's fall of 0.56%. The stock opened with a gap-up of 2.15% and touched an intraday high of ₹272.3, up 2.91% from the previous close.
Technically, ONGC is trading above its 20-day, 50-day, 100-day, and 200-day moving averages, signalling a sustained uptrend. However, it remains slightly below its 5-day moving average, indicating some short-term consolidation or profit booking. The stock's high dividend yield of 5.2% further adds to its appeal for income-focused investors.
Market Positioning and Investor Behaviour
The rising open interest in derivatives suggests that traders are increasingly bullish on ONGC’s near-term prospects. The increase in OI by over 13,700 contracts, combined with strong volume, points to fresh long positions being built rather than short covering. This is reinforced by the stock’s outperformance relative to its sector and benchmark indices.
Interestingly, delivery volumes have declined by 40.77% to 63.81 lakh shares on 18 Feb compared to the 5-day average, indicating that while short-term trading activity is robust, longer-term investor participation may be moderating. This divergence often reflects speculative positioning in the derivatives market ahead of anticipated catalysts or earnings announcements.

Implications of the Open Interest Surge
The 11.27% rise in open interest is significant for a large-cap stock like ONGC, which commands a market capitalisation of ₹3,39,668 crores. This increase suggests that institutional and retail traders alike are positioning for a potential upward move in the stock price. The futures and options data imply that directional bets are being placed, possibly anticipating positive developments in the oil sector or company-specific catalysts.
Given the stock’s proximity to its 52-week high and strong dividend yield, investors may be factoring in sustained earnings growth or favourable crude oil price trends. The sector’s recent underperformance relative to ONGC also highlights the stock’s relative strength, which could attract further buying interest.
Mojo Score Upgrade and Market Sentiment
MarketsMOJO has upgraded ONGC’s Mojo Grade from Hold to Buy as of 5 Feb 2026, reflecting improved fundamentals and technical outlook. The current Mojo Score stands at 75.0, signalling a strong buy recommendation. This upgrade aligns with the observed surge in derivatives open interest and positive price momentum, reinforcing the bullish sentiment surrounding the stock.
Additionally, ONGC’s liquidity remains robust, with the stock capable of handling trade sizes up to ₹10.16 crores based on 2% of its 5-day average traded value. This ensures that increased market activity can be absorbed without excessive price volatility, making it an attractive option for large institutional trades.
Risks and Considerations
Despite the positive signals, investors should remain cautious of potential short-term volatility. The slight dip below the 5-day moving average and falling delivery volumes suggest some profit-taking or uncertainty among longer-term holders. Moreover, the oil sector remains sensitive to global crude price fluctuations, geopolitical tensions, and regulatory changes, which could impact ONGC’s performance.
Traders should also monitor the derivatives market closely for any sudden unwinding of positions or shifts in put-call ratios that may indicate changing sentiment. A sustained rise in open interest accompanied by price gains typically confirms bullish conviction, but divergence between these metrics can signal caution.

Conclusion: A Bullish Tilt with Cautious Optimism
The recent surge in open interest and volume in ONGC’s derivatives market, combined with strong price performance and a Mojo Grade upgrade, points to a bullish tilt among market participants. The stock’s proximity to its 52-week high and attractive dividend yield further bolster its appeal.
However, investors should weigh these positives against the backdrop of falling delivery volumes and sectoral risks. Monitoring ongoing derivatives activity and technical indicators will be crucial to gauge the sustainability of this momentum. For now, ONGC remains a compelling large-cap oil sector pick with growing market conviction behind it.
