Open Interest and Volume Dynamics
On 25 Jun 2026, ONGC’s open interest (OI) in derivatives rose sharply by 14.9%, climbing from 1,10,708 contracts to 1,27,207 contracts. This increase of 16,499 contracts is substantial, especially given the backdrop of a declining stock price. The futures volume stood at 71,284 contracts, with a futures value of approximately ₹1,41,675 lakhs and an options value reaching an extraordinary ₹25,179.68 crores, culminating in a total derivatives value of ₹1,44,974 lakhs. This data underscores heightened trading activity and interest in the stock’s derivatives, signalling that market participants are actively repositioning their portfolios.
Price Performance and Technical Context
ONGC’s underlying stock price closed at ₹233, just 2.47% above its 52-week low of ₹228.61. The stock has been on a downward trajectory for four consecutive sessions, shedding 4.81% over this period. Intraday, the price touched a low of ₹233.55, reflecting persistent selling pressure. Notably, the weighted average price indicates that most volume traded near the day’s low, suggesting that sellers dominated the session.
Technically, ONGC is trading below all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — signalling a bearish trend across multiple timeframes. This technical weakness is compounded by falling investor participation, with delivery volumes on 24 Jun dropping by 12.97% compared to the five-day average, indicating reduced conviction among long-term holders.
Market Positioning and Potential Directional Bets
The surge in open interest amid a falling price often points to fresh short positions being established or increased hedging activity. However, the sizeable volume and value in options suggest that some investors may be positioning for volatility or potential rebounds through strategic option plays. The elevated options value, particularly, hints at complex strategies such as spreads or straddles being employed to capitalise on expected price movements.
Given ONGC’s high dividend yield of 5.74%, some investors might be balancing income generation with cautious exposure to price fluctuations. The large-cap status and a Market Capitalisation of ₹2,94,755.94 crores further attract institutional interest, which can amplify derivatives activity as these players adjust their risk profiles.

Comparative Sector and Market Performance
In contrast to ONGC’s 1-day return of -2.38%, the Oil sector declined by a milder 0.23%, while the broader Sensex index advanced by 0.33%. This relative underperformance highlights the stock’s current weakness within its sector and the market at large. The divergence between ONGC’s price action and the Sensex’s positive movement may be a factor driving the increased derivatives activity, as traders seek to hedge or speculate on a potential turnaround.
Mojo Score and Analyst Ratings
MarketsMOJO assigns ONGC a Mojo Score of 64.0, categorising it with a Hold rating. This represents a downgrade from a previous Buy rating on 24 Jun 2026, reflecting a reassessment of the stock’s near-term prospects amid recent price declines and technical weakness. The Hold grade suggests that while the company remains fundamentally sound, caution is warranted given current market conditions and price momentum.
Liquidity and Trading Considerations
Liquidity remains adequate for ONGC, with the stock’s trading volume supporting trade sizes up to ₹5.38 crores based on 2% of the five-day average traded value. This ensures that institutional and retail investors can execute sizeable trades without significant market impact, which is crucial for derivatives market participants managing large positions.

Outlook and Investor Implications
The recent spike in open interest and derivatives volume for ONGC signals a market at a crossroads. While the stock’s technical indicators and recent price action point to bearish momentum, the heightened derivatives activity suggests that investors are actively recalibrating their positions, possibly anticipating a near-term reversal or increased volatility.
Investors should closely monitor changes in open interest alongside price movements to discern whether fresh buying interest emerges or if short positions continue to build. The substantial options market activity also warrants attention, as it may provide clues on expected price ranges and volatility in the coming sessions.
Given ONGC’s large-cap stature, attractive dividend yield, and strategic importance in the oil sector, it remains a key stock for market participants. However, the downgrade to a Hold rating by MarketsMOJO reflects the need for caution and a balanced approach amid current uncertainties.
Summary
In summary, the surge in open interest for Oil & Natural Gas Corporation Ltd. amid a declining price trend highlights a complex market environment where investors are actively repositioning. The interplay of technical weakness, dividend attractiveness, and robust derivatives activity suggests a nuanced outlook. Market participants should remain vigilant, analysing both price and open interest trends to navigate potential directional shifts effectively.
