Open Interest and Volume Dynamics
The latest data reveals that Hindustan Petroleum’s open interest (OI) in derivatives rose sharply by 4,552 contracts, a 20.86% increase from the previous day’s 21,820 to 26,372. This notable expansion in OI was accompanied by a substantial volume of 36,699 contracts traded, underscoring active participation from both institutional and retail investors. The futures value stood at ₹52,141.29 lakhs, while the options segment exhibited an enormous notional value of approximately ₹32,058.75 crores, culminating in a total derivatives value of ₹59,346.56 lakhs.
Such a pronounced rise in open interest alongside elevated volume typically signals fresh positions being established rather than existing ones being squared off. This pattern often indicates a strong conviction among market participants regarding the stock’s near-term directional movement.
Price Action and Technical Strength
On the price front, Hindustan Petroleum touched an intraday high of Rs 497.5, marking a new 52-week peak and registering a day gain of 6.13%. This performance outpaced the Oil Exploration and Refining sector’s 2.61% gain and the Sensex’s modest 0.94% rise, highlighting the stock’s relative strength. The closing price reflected a 5.91% increase, further cementing bullish momentum.
Technically, the stock is trading above all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — indicating a robust uptrend across multiple timeframes. This alignment of moving averages often attracts momentum traders and institutional buyers, reinforcing the positive price trajectory.
Investor Participation and Delivery Volumes
Investor engagement has surged notably, with delivery volumes on 30 Dec reaching 27.95 lakh shares, a staggering 212.24% increase compared to the five-day average delivery volume. This spike in delivery volume suggests that investors are not merely trading for short-term gains but are willing to hold the stock, reflecting confidence in its fundamentals and growth prospects.

Market Positioning and Directional Bets
The surge in open interest combined with rising prices and volumes suggests that market participants are positioning for further upside in Hindustan Petroleum. The increase in OI by over 20% indicates fresh long positions being built, likely reflecting bullish sentiment on the stock’s near-term prospects.
Options market data, with an enormous notional value exceeding ₹32,000 crores, points to active call option buying, which typically signals expectations of price appreciation. Put option activity remains comparatively subdued, reinforcing the skew towards bullish bets.
Given the stock’s strong fundamentals, including a high dividend yield of 3.31% and a market capitalisation of ₹1,05,635.75 crore placing it firmly in the mid-cap category, investors appear confident in its ability to sustain growth amid a recovering oil sector.
Fundamental and Technical Upgrades
MarketsMOJO has upgraded Hindustan Petroleum’s Mojo Grade from Buy to Strong Buy as of 30 Dec 2025, reflecting improved financial metrics and positive trend assessments. The Mojo Score stands at a robust 81.0, signalling strong conviction among analysts regarding the stock’s upside potential.
The company’s market cap grade remains at 2, consistent with its mid-cap status, but the recent upgrade in rating underscores enhanced quality and momentum. This upgrade is likely to attract further institutional interest, potentially driving volumes and prices higher in the coming sessions.
Sectoral Context and Comparative Performance
The Oil Exploration and Refining sector has gained 2.61% on the day, supported by improving crude oil prices and easing supply concerns globally. Hindustan Petroleum’s outperformance by nearly 3.42% relative to its sector peers highlights its leadership position and superior market sentiment.
Compared to the Sensex’s 0.94% gain, the stock’s 5.91% return is particularly noteworthy, signalling strong relative strength and investor preference. This outperformance is further validated by the stock’s ability to sustain levels above all major moving averages, a technical hallmark of a healthy uptrend.

Outlook and Investor Takeaways
With open interest surging by over 20%, accompanied by strong volume and price appreciation, Hindustan Petroleum is signalling a clear bullish bias among derivatives traders. The stock’s technical strength, combined with improving fundamentals and a recent upgrade to Strong Buy, suggests that investors are positioning for sustained gains.
However, investors should remain mindful of broader macroeconomic factors such as crude oil price volatility, regulatory changes, and global energy demand trends, which could influence the stock’s trajectory. The current high delivery volumes and liquidity provide a favourable environment for both long-term investors and traders to participate actively.
In summary, the confluence of rising open interest, robust price action, and positive fundamental upgrades positions Hindustan Petroleum as a compelling mid-cap opportunity within the oil sector, warranting close attention from market participants.
