Open Interest and Volume Dynamics
On the last trading day of 2025, BPCL’s open interest in futures and options contracts rose sharply by 2,182 contracts, an 11.79% increase from the previous OI of 18,509 to 20,691. This notable expansion in OI accompanied a volume of 21,830 contracts, indicating strong participation from traders and investors. The futures segment alone accounted for a value of approximately Rs 28,728.77 lakhs, while the options segment’s notional value was substantially higher at Rs 13,834.53 crores, culminating in a total derivatives value of Rs 31,550.85 lakhs.
This surge in open interest, combined with elevated volumes, suggests fresh positions are being established rather than existing ones being squared off. Such a pattern often signals a conviction in the underlying stock’s near-term price trajectory, with market participants positioning for a directional move.
Price Action and Technical Strength
BPCL’s price action on 31 Dec was notably bullish. The stock touched an intraday high of Rs 384.4, marking a new 52-week high and registering a day gain of 3.87%, outperforming the Oil Exploration/Refineries sector’s 2.28% advance and the Sensex’s modest 0.68% rise. The weighted average price indicated that more volume traded closer to the low price of the day, which can sometimes reflect cautious accumulation.
Technically, BPCL is trading above all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — underscoring a strong uptrend. This technical positioning supports the bullish sentiment reflected in the derivatives market.
Sector and Market Context
The oil sector has been gaining momentum, with the Oil Exploration/Refineries index rising 2.28% on the day. BPCL’s outperformance relative to its sector peers highlights its leadership within the space. The company’s large market capitalisation of Rs 1,66,533.53 crores and high liquidity, with a trade size capacity of Rs 3.37 crores based on 2% of the 5-day average traded value, make it an attractive stock for institutional and retail investors alike.
Investor participation has also surged, with delivery volumes on 30 Dec rising by 183.33% to 52.37 lakh shares compared to the 5-day average. This increase in delivery volume indicates genuine buying interest rather than speculative trading.

Market Positioning and Directional Bets
The increase in open interest alongside rising prices and volumes suggests that market participants are taking fresh bullish positions in BPCL. The 11.79% rise in OI is significant in the context of the stock’s recent momentum and sectoral tailwinds. Traders appear to be betting on further upside, supported by the stock’s strong fundamentals and technical setup.
BPCL’s current dividend yield of 4.74% at the prevailing price adds an attractive income component for investors, further bolstering its appeal. The stock’s mojo score of 81.0, upgraded from a previous ‘Buy’ to a ‘Strong Buy’ rating on 12 Dec 2025, reflects improved financial health, valuation, and technical strength. This upgrade by MarketsMOJO reinforces the positive outlook and may be influencing increased participation in derivatives.
Valuation and Quality Metrics
BPCL’s mojo grade of ‘Strong Buy’ is supported by a market cap grade of 1, indicating its status as a large-cap stock with robust market presence. The upgrade from ‘Buy’ to ‘Strong Buy’ within the last three weeks highlights the company’s improving fundamentals and investor confidence. The stock’s liquidity profile ensures that large trades can be executed without significant price impact, an important consideration for institutional investors.
