Open Interest and Volume Dynamics
On 27 Jan 2026, Hindustan Petroleum’s open interest (OI) in derivatives rose sharply by 4,077 contracts, an 11.32% increase from the previous tally of 36,020 to 40,097. This expansion in OI was accompanied by a futures volume of 20,976 contracts, reflecting heightened trading activity. The combined futures and options value stood at approximately ₹94,611.33 lakhs, with futures contributing ₹92,504.04 lakhs and options dominating at ₹8,978.89 crores, underscoring the significant liquidity and interest in the stock’s derivatives.
The underlying stock price closed at ₹416, registering a 0.48% gain on the day, outperforming the oil sector’s 0.14% rise and the Sensex’s marginal decline of 0.06%. This price uptick followed five consecutive sessions of decline, suggesting a potential trend reversal or at least a pause in the downtrend.
Market Positioning and Investor Sentiment
The surge in open interest alongside rising volume typically indicates fresh capital entering the market, either through new long positions or increased short hedging. Given the stock’s recent underperformance relative to its moving averages—trading below its 5-day, 20-day, 50-day, 100-day, and 200-day averages—investors appear to be positioning for a possible rebound or volatility ahead.
Supporting this view, delivery volumes on 23 Jan surged to 34.8 lakh shares, a 25.96% increase over the five-day average, signalling stronger investor participation in the cash market. This rise in delivery volume often reflects genuine buying interest rather than speculative trading, which could underpin a more sustainable price recovery.

Technical and Fundamental Context
Despite the recent price improvement, Hindustan Petroleum remains in a technically weak position, trading below all major moving averages. This suggests that while short-term buying interest has emerged, the stock has yet to confirm a sustained uptrend. Investors should note that the company’s current Mojo Score stands at 64.0 with a Mojo Grade of Hold, downgraded from Buy on 22 Jan 2026, reflecting a cautious stance amid mixed signals.
From a fundamental perspective, Hindustan Petroleum’s market capitalisation is ₹88,603 crore, categorising it as a mid-cap stock within the oil sector. The company offers a relatively attractive dividend yield of 3.73%, which may appeal to income-focused investors amid volatile price movements.
Interpreting the Open Interest Surge
The 11.32% increase in open interest is significant in the context of the stock’s recent price action. Typically, rising OI with rising prices indicates fresh long positions, suggesting bullish sentiment. Conversely, rising OI with falling prices often points to increased short selling or hedging activity. In this case, the stock’s modest price gain alongside the OI surge hints at a cautious but optimistic market outlook.
Moreover, the futures value of ₹92,504 lakhs and the overwhelming options value of nearly ₹8,978 crores indicate that options traders are actively positioning, possibly through strategies such as protective puts or call spreads to capitalise on expected volatility or directional moves.
Sector and Market Comparison
Hindustan Petroleum’s outperformance relative to the oil sector and the broader Sensex on the day is noteworthy. The oil sector’s 0.14% gain was modest, while the Sensex declined slightly, underscoring the stock’s relative strength. This may reflect company-specific factors or investor anticipation of positive catalysts such as favourable crude oil prices, government policy support, or improved refining margins.
Liquidity remains adequate for sizeable trades, with the stock’s average traded value supporting transactions up to ₹4.36 crore based on 2% of the five-day average traded value. This ensures that institutional investors can enter or exit positions without significant market impact.

Investor Takeaways and Outlook
For investors, the recent open interest surge in Hindustan Petroleum’s derivatives signals increased market attention and potential positioning for a directional move. The stock’s technical weakness advises caution, but the rising delivery volumes and price rebound after a five-day slide suggest that buyers are stepping in.
Given the Hold rating and the downgrade from Buy, investors should weigh the risks of further downside against the possibility of a technical recovery. Monitoring open interest trends, volume patterns, and price action in the coming sessions will be crucial to gauge whether this surge represents a genuine shift in sentiment or a short-lived speculative spike.
Additionally, the company’s attractive dividend yield and mid-cap status may continue to draw interest from income-oriented and value investors, especially if sector fundamentals improve.
Conclusion
Hindustan Petroleum Corporation Ltd. is currently at a crossroads, with a significant open interest increase in its derivatives market reflecting heightened investor engagement. While the stock has shown signs of a short-term rebound, its technical indicators remain subdued, and the recent Mojo Grade downgrade signals caution. Investors should closely monitor evolving market positioning and sector developments to make informed decisions in this volatile environment.
