Oil & Natural Gas Corporation Ltd. Faces Mixed Sentiment: -0.91% Weekly Decline Amid Divergent Option Activity

13 April: High-Value Trading Amid Sector Weakness

ONGC emerged as one of the most actively traded stocks by value on 13 April 2026, with a substantial turnover of approximately ₹2,286.88 crores on a volume of 79.93 lakh shares. Despite this liquidity, the stock price declined modestly by 1.55% intraday, closing at Rs.282.00 as of 09:44 IST, reflecting a short-term correction within a broader sectoral downturn.

The Oil Exploration and Refinery sector fell by 2.56% that day, while the Sensex declined 0.76%, indicating ONGC’s relative resilience. The stock traded near its 52-week high of Rs.293, just 3.94% below the peak, signalling underlying strength despite the sector’s weakness.

Technically, ONGC remained above its 20-day, 50-day, 100-day, and 200-day moving averages, confirming a sustained medium- to long-term uptrend. However, it slipped below the 5-day moving average, consistent with the short-term price dip. The company’s high dividend yield of 4.81% and large market capitalisation of ₹3,54,889.68 crores continue to support investor interest.

13 April: Bullish Call Option Activity Ahead of April Expiry

On the derivatives front, ONGC saw heavy call option activity concentrated at the ₹290 strike price expiring on 28 April 2026. With 4,250 contracts traded and an open interest of 4,989 contracts, this surge indicates bullish sentiment among traders anticipating a near-term upside breakout.

This call option volume is notable given the underlying stock price of Rs.281.85 at the time, suggesting expectations of a rally beyond recent resistance levels. The turnover of approximately ₹4.99 crores in call options underscores significant market optimism despite the underlying stock’s minor price setback.

Such positioning often reflects anticipation of positive catalysts or sectoral tailwinds, supported by ONGC’s upgraded Mojo Grade to Buy and a Mojo Score of 75.0 as of 19 March 2026. The stock’s ability to outperform its sector peers during this period further bolsters this outlook.

13 April: Bearish Put Option Activity Signals Caution

Contrasting the bullish call option interest, ONGC also experienced significant put option volumes at the ₹280 and ₹250 strike prices ahead of the 28 April expiry. The ₹280 strike put saw 1,478 contracts traded with an open interest of 1,550 contracts, while the ₹250 strike put recorded 1,851 contracts traded and an open interest of 859 contracts.

This surge in put options suggests a growing bearish positioning or hedging activity among investors, reflecting concerns over potential near-term downside risks. The near-the-money ₹280 strike put activity indicates protective measures against moderate declines, while the ₹250 strike put interest points to speculation on a sharper correction.

Despite the stock’s proximity to its 52-week high and strong fundamentals, the derivatives market reveals a nuanced sentiment where investors balance optimism with caution amid sector volatility and declining delivery volumes, which fell by over 50% on 10 April compared to the five-day average.

15 April: Marginal Price Stability Amid Market Rally

After the weekend, ONGC’s stock price remained largely unchanged on 15 April, closing at Rs.287.55, a marginal increase of 0.02%. This stability came despite a strong Sensex rally of 1.89%, reflecting a cautious stance among investors amid mixed signals from the derivatives market.

Volume declined to 5.19 lakh shares, indicating reduced trading activity. The stock’s performance on this day suggests consolidation as market participants awaited further clarity on sector trends and expiry dynamics.

16 April: Sharp Decline on Lower Volumes

On 16 April, ONGC’s share price fell sharply by 1.67% to Rs.282.75 on relatively lower volume of 3.43 lakh shares. This decline contrasted with the Sensex’s modest gain of 0.26%, signalling stock-specific pressure possibly linked to the ongoing bearish put option activity and short-term profit booking.

The stock’s dip below the 5-day moving average persisted, reinforcing the short-term technical weakness despite the longer-term uptrend remaining intact.

17 April: Modest Recovery to Close the Week

In the final trading session of the week, ONGC rebounded modestly by 0.42% to close at Rs.283.95 on increased volume of 7.93 lakh shares. This recovery, however, was insufficient to offset the week’s losses, as the stock ended 0.91% lower than the previous Friday’s close.

The Sensex continued its upward trajectory, gaining 0.94% on the day and 2.33% for the week, highlighting ONGC’s relative underperformance. The stock’s mixed weekly performance reflects the interplay of bullish fundamentals and cautious market positioning amid sectoral challenges.

Key Takeaways

ONGC’s week was characterised by a complex interplay of strong institutional interest, mixed derivatives market signals, and sectoral headwinds. The stock’s high-value trading on 13 April amid a weak oil sector demonstrated sustained investor focus and liquidity, supported by its large-cap status and attractive dividend yield of 4.81%.

However, the simultaneous heavy call and put option activity ahead of the 28 April expiry highlighted divergent market expectations. While call option volumes at the ₹290 strike price indicated bullish anticipation of a breakout, significant put option interest at ₹280 and ₹250 strikes suggested hedging and bearish sentiment, reflecting caution amid recent price volatility.

Technically, ONGC maintained a medium- to long-term uptrend, trading above key moving averages, but short-term weakness was evident as the stock slipped below its 5-day moving average and experienced a two-day consecutive decline. The week’s closing price of Rs.283.95 represented a 0.91% loss, underperforming the Sensex’s 2.33% gain.

Investor participation appeared to wane, with delivery volumes dropping sharply, signalling a possible shift towards short-term trading or profit booking. The upcoming expiry on 28 April is likely to be a critical period for price volatility and directional moves, as option traders adjust positions.

Conclusion

Oil & Natural Gas Corporation Ltd. concluded the week on a cautious note, balancing strong fundamental credentials against mixed technical and derivatives market signals. The stock’s large-cap stature, high dividend yield, and recent Mojo Grade upgrade to Buy underpin a positive medium-term outlook. However, the pronounced put option activity and short-term price softness suggest investors are hedging against potential near-term risks amid sectoral uncertainties.

As the April expiry approaches, market participants should closely monitor price action and option market dynamics to gauge the evolving sentiment. ONGC’s performance this week underscores the importance of a balanced approach that considers both fundamental strengths and technical caution in navigating the energy sector landscape.
