Open Interest and Volume Dynamics
On 20 Feb 2026, Hindustan Petroleum’s open interest (OI) in futures and options contracts rose sharply to 38,753 contracts from 34,968 the previous day, marking an increase of 3,785 contracts or 10.82%. This rise in OI was accompanied by a robust trading volume of 35,837 contracts, indicating strong participation in the derivatives market. The futures value stood at ₹99,864.6 lakhs, while the options segment exhibited an enormous notional value of ₹21,562.3 crores, culminating in a total derivatives value exceeding ₹1,02,346.8 lakhs.
The underlying stock price closed at ₹434, down 1.06% on the day, underperforming the Oil sector’s gain of 0.58% and the Sensex’s 0.62% rise. This divergence between rising open interest and falling price suggests that market participants may be increasing bearish bets or hedging existing long positions amid uncertainty.
Price Performance and Technical Context
Hindustan Petroleum has been on a downward trajectory, losing 5.89% over the past two trading sessions. The stock is currently trading below all key moving averages – 5-day, 20-day, 50-day, 100-day, and 200-day – signalling a sustained bearish trend. This technical weakness is compounded by rising delivery volumes, which surged to 28.64 lakh shares on 19 Feb, a 235.6% increase over the five-day average, indicating heightened investor participation and possible long liquidation.
Despite the recent price softness, the stock offers a relatively attractive dividend yield of 3.57%, which may provide some support to long-term investors. Liquidity remains adequate, with the stock able to absorb trade sizes up to ₹1.96 crore based on 2% of the five-day average traded value, ensuring smooth execution for institutional players.

Market Positioning and Potential Directional Bets
The surge in open interest alongside declining prices typically indicates that fresh short positions are being established or that existing longs are being hedged more aggressively. Given the 10.8% rise in OI and the 1.06% price drop, it is plausible that traders are positioning for further downside or volatility in Hindustan Petroleum’s shares.
Options data, with a notional value exceeding ₹21,562 crores, suggests significant activity in put options, which are often used to protect against downside risk or to speculate on price falls. The futures market’s substantial value of nearly ₹1,00,000 lakhs also points to increased speculative or hedging interest. This combination of derivatives activity may reflect concerns over near-term earnings, crude oil price fluctuations, or sector-specific regulatory developments.
Fundamental and Sectoral Context
Hindustan Petroleum operates in the Oil industry, a sector that has shown mixed performance recently due to global energy market volatility and geopolitical tensions. The company’s market capitalisation stands at ₹91,443.17 crore, categorising it as a mid-cap stock. Its Mojo Score of 74.0 and upgraded Mojo Grade from Hold to Buy as of 9 Feb 2026 indicate improving fundamentals and positive analyst sentiment, despite the short-term price weakness.
However, the stock’s recent underperformance relative to the sector and Sensex highlights the challenges it faces. Investors should weigh the attractive dividend yield and improving fundamentals against the technical downtrend and increased bearish positioning in derivatives.

Implications for Investors
For investors, the current scenario presents a nuanced picture. The rising open interest and volume in derivatives suggest that market participants are actively repositioning, possibly anticipating further downside or increased volatility. The technical indicators reinforce a bearish near-term outlook, with the stock trading below all major moving averages and showing consecutive declines.
Conversely, the company’s fundamental upgrades and solid dividend yield provide a cushion for long-term holders. Those considering fresh exposure should monitor the derivatives activity closely, as sustained increases in open interest coupled with falling prices often precede significant price moves. Risk-averse investors may prefer to wait for confirmation of a trend reversal or stabilisation in price action before committing.
Institutional traders and hedge funds might be utilising options strategies to hedge existing positions or speculate on volatility, which could lead to sharp intraday swings. Retail investors should exercise caution and consider the broader macroeconomic and sectoral factors influencing oil prices and refining margins.
Conclusion
Hindustan Petroleum Corporation Ltd. is currently experiencing a significant surge in derivatives open interest amid a weakening price trend. This divergence points to increased bearish sentiment or hedging activity in the market. While the company’s fundamentals and dividend yield remain attractive, the technical and derivatives data suggest caution in the near term. Investors should closely monitor open interest trends, volume patterns, and price action to gauge the evolving market positioning and potential directional bets on this mid-cap oil stock.
