Open Interest and Volume Dynamics
On 28 Sep 2026, BPCL’s open interest (OI) in derivatives rose sharply to 33,071 contracts from a previous 29,890, marking an increase of 3,181 contracts or 10.64%. This expansion in OI is accompanied by a futures volume of 16,440 contracts, reflecting active participation in the derivatives market. The futures value stood at ₹45,378.11 lakhs, while the options segment exhibited a substantial notional value of approximately ₹5,515.81 crores, culminating in a total derivatives value of ₹46,095.40 lakhs.
Such a rise in open interest typically indicates fresh capital entering the market, either through new long or short positions. Given the concurrent price decline, this suggests that traders may be positioning for further downside or hedging existing exposures.
Price Performance and Technical Context
BPCL’s share price opened with a gap down of -2.04%, touching an intraday low of ₹302.15, down 2.06% on the day. The stock traded within a narrow range of just ₹0.25, signalling subdued volatility despite the negative bias. Importantly, BPCL is trading below all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — underscoring a sustained bearish trend.
The oil exploration and refinery sector, to which BPCL belongs, also declined by 2.02%, mirroring the stock’s underperformance. The Sensex fell by 1.59%, while the sector’s 1-day return was -1.92%, placing BPCL’s 1-day return of -2.01% slightly below sector and benchmark indices.
Investor Participation and Liquidity Considerations
Investor participation appears to be waning, with delivery volumes on 25 Sep falling sharply by 73.69% compared to the 5-day average, registering only 10.19 lakh shares. This decline in delivery volume suggests reduced conviction among long-term investors, possibly reflecting caution amid the stock’s recent weakness.
Despite this, liquidity remains adequate for sizeable trades, with the stock’s average traded value supporting a trade size of approximately ₹2.85 crores based on 2% of the 5-day average traded value. This ensures that institutional investors can execute orders without significant market impact.

Market Positioning and Potential Directional Bets
The increase in open interest amid falling prices suggests that market participants are either initiating fresh short positions or hedging existing long exposures. The narrow intraday trading range indicates a consolidation phase, where traders may be awaiting further cues before committing decisively.
BPCL’s current Mojo Score of 44.0 and a Mojo Grade of Sell, downgraded from Hold on 1 Sep 2026, reflect a deteriorated outlook based on MarketsMOJO’s comprehensive analysis. The downgrade aligns with the technical weakness and subdued investor sentiment observed in recent sessions.
Moreover, BPCL’s high dividend yield of 5.69% at the current price level may provide some support to long-term investors, but the prevailing negative momentum and sectoral headwinds are likely to weigh on near-term performance.
Sectoral and Macro Considerations
The oil sector continues to face pressure from global crude price volatility and regulatory challenges. BPCL, as a large-cap player with a market capitalisation of ₹1,32,281 crores, is not immune to these macroeconomic factors. The sector’s 1-day decline of 2.02% indicates broad-based selling pressure, which may be exacerbated by concerns over demand outlook and refining margins.
Investors should also note the stock’s position relative to moving averages, which suggests that any short-term rallies may encounter resistance near these technical levels, particularly the 50-day and 100-day averages.

Implications for Investors
For investors and traders, the surge in open interest combined with bearish price action signals caution. The derivatives market activity suggests that participants are bracing for further downside or increased volatility. Those holding long positions may consider protective strategies such as stop-loss orders or hedging through options.
Conversely, speculative traders might view the current setup as an opportunity to capitalise on potential downward momentum, especially given the stock’s technical weakness and sectoral pressures.
Long-term investors should weigh the attractive dividend yield against the deteriorating technical and fundamental outlook, monitoring for signs of stabilisation before increasing exposure.
Conclusion
Bharat Petroleum Corporation Ltd’s recent open interest surge in derivatives, amid a declining share price and subdued sector performance, highlights a market environment characterised by increased caution and repositioning. The downgrade to a Sell rating by MarketsMOJO and the stock’s trading below key moving averages reinforce the bearish sentiment.
Investors should remain vigilant, analysing volume and open interest trends alongside broader sector and macroeconomic developments to navigate the evolving landscape effectively.
