Surge in Open Interest Signals Shifting Market Sentiment for Oil & Natural Gas Corporation Ltd.

Open Interest and Volume Dynamics

Recent data reveals that ONGC's open interest in derivatives rose sharply by 11.96%, climbing from 85,532 contracts to 95,762 contracts. This increase of 10,230 contracts indicates a robust build-up of positions, suggesting that traders are actively taking stances on the stock's near-term price movement. The volume for the day stood at 63,061 contracts, underscoring strong participation in the derivatives market.

The futures value associated with ONGC contracts reached ₹1,04,884.07 lakhs, while the options segment exhibited an underlying value of ₹23,513.81 crores. The combined total derivatives value stood at ₹1,06,583.97 lakhs, reflecting substantial liquidity and interest in the stock's derivatives instruments.

Price Performance and Moving Averages

ONGC's underlying share price closed at ₹235, registering a modest gain of 0.25% on the day. This performance outpaced the Oil sector, which declined by 0.53%, and the Sensex, which fell 0.41%. The stock has recorded gains over the past two consecutive sessions, accumulating a 0.64% return during this period.

Technically, the stock is trading above its 5-day moving average but remains below its 20-day, 50-day, 100-day, and 200-day moving averages. This positioning suggests short-term strength but indicates that the broader trend remains under pressure, requiring sustained momentum to break through longer-term resistance levels.

Investor Participation and Dividend Appeal

Despite the positive price action, investor participation appears to be waning. Delivery volume on 26 Dec was 22.11 lakh shares, down 24.73% compared to the 5-day average delivery volume. This decline in physical shareholding transfer may imply that the recent gains are driven more by speculative trading in derivatives rather than long-term accumulation.

ONGC continues to offer an attractive dividend yield of 5.33% at the current price, which remains a key draw for income-focused investors amid volatile market conditions.

Market Positioning and Directional Bets

The notable rise in open interest alongside elevated volumes suggests that market participants are positioning for a directional move in ONGC. The increase in OI typically reflects fresh capital entering the market, either through new long or short positions. Given the stock’s recent outperformance relative to its sector and benchmark indices, the bias appears to be tilted towards bullish bets.

However, the stock’s placement below key moving averages signals caution. Traders may be anticipating a breakout above these resistance levels, which could trigger further upside momentum. Conversely, failure to sustain gains could lead to profit-taking and a reversal in sentiment.

Options market data, with a substantial underlying value, indicates active hedging and speculative strategies. The large notional value in options contracts points to complex positioning, including spreads and straddles, which investors use to capitalise on volatility or directional moves while managing risk.

Mojo Score and Analyst Ratings

MarketsMOJO assigns ONGC a Mojo Score of 58.0, categorising it with a Hold grade as of 8 Dec 2025, a downgrade from its previous Buy rating. This adjustment reflects a more cautious stance amid mixed technical signals and fluctuating investor participation. The company holds a Market Cap Grade of 1, indicating its status as a large-cap stock with significant market presence.

Investors should weigh the stock’s attractive dividend yield and recent price resilience against the tempered analyst outlook and technical hurdles. The stock’s liquidity, sufficient to support trade sizes of approximately ₹2.28 crore based on 2% of the 5-day average traded value, ensures ease of entry and exit for institutional and retail participants alike.

Sector and Market Context

ONGC operates within the Oil industry, a sector currently facing headwinds from fluctuating crude prices and geopolitical uncertainties. Despite these challenges, ONGC’s large-cap status and steady dividend yield provide a defensive quality that appeals to conservative investors.

The stock’s recent outperformance relative to the Oil sector’s 0.53% decline and the Sensex’s 0.41% fall highlights its relative strength. This resilience may attract further interest from investors seeking stability amid broader market volatility.

However, the decline in delivery volumes suggests that the rally is primarily driven by derivatives trading rather than sustained accumulation in the cash market. This dynamic warrants close monitoring, as a divergence between derivatives activity and physical market participation can lead to increased volatility.

Outlook and Investor Considerations

In summary, the surge in open interest and volume in ONGC’s derivatives market signals active positioning and potential directional bets, predominantly on the upside. The stock’s technical setup, dividend yield, and relative strength within its sector provide a mixed but cautiously optimistic outlook.

Investors should remain vigilant of key moving average resistance levels and monitor delivery volumes for signs of genuine accumulation. The downgrade to a Hold rating by MarketsMOJO reflects the need for a balanced approach, combining dividend income with tactical trading strategies to navigate near-term uncertainties.

Given the stock’s liquidity and market cap, ONGC remains a viable option for both institutional and retail investors seeking exposure to India’s oil sector, provided they manage risk appropriately and stay attuned to evolving market signals.
