Open Interest and Volume Dynamics
The latest data reveals that open interest in Cummins India’s futures and options contracts surged by 10,014 contracts, a substantial 33.9% increase from the previous figure of 29,538 to 39,552. This sharp rise in OI is accompanied by a robust volume of 1,25,909 contracts traded, underscoring active participation from market participants. The futures value stood at approximately Rs 66,428.4 lakhs, while the options segment exhibited an enormous notional value of Rs 1,14,121.7 crores, culminating in a total derivatives value of Rs 77,512.3 lakhs.
The underlying stock price has been on an upward trajectory, currently trading at Rs 4,745, which is well above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. This technical strength is further validated by the stock’s outperformance relative to its sector, gaining 3.02% on the day compared to the Diesel Engines sector’s 2.4% rise and the Sensex’s marginal decline of 0.02%.
Price Momentum and Market Positioning
Cummins India has recorded a consecutive three-day gain, delivering a cumulative return of 7.36% during this period. The stock’s intraday high of Rs 4,786.4 represents a fresh 52-week peak, signalling renewed bullish sentiment. Investor participation has also intensified, with delivery volumes rising to 2.81 lakh shares on 17 Feb 2026, marking a 27.84% increase over the five-day average delivery volume. This suggests that investors are not only trading actively but also accumulating shares for the longer term.
Liquidity remains healthy, with the stock’s traded value supporting sizeable trade sizes up to Rs 3.64 crore based on 2% of the five-day average traded value. This liquidity profile is favourable for institutional investors and traders looking to establish or unwind positions without significant market impact.

Interpreting the Open Interest Surge
The 33.9% jump in open interest is a clear indication of fresh positions being established in the derivatives market. Such a rise often reflects increased conviction among traders regarding the stock’s near-term direction. Given the concurrent price appreciation and volume expansion, it is plausible that the majority of these new contracts are bullish bets, either through futures long positions or call option buying.
Moreover, the stock’s upgrade in MarketsMOJO’s mojo grade from Buy to Hold on 24 Dec 2025, with a mojo score of 65.0, suggests a more cautious stance by analysts, possibly factoring in valuation concerns after the recent rally. Despite this, the market’s positioning appears optimistic, as evidenced by the sustained gains and rising open interest.
Sectoral and Market Context
The Diesel Engines sector, to which Cummins India belongs, has gained 2.4% on the day, indicating broad-based strength. Cummins India’s outperformance relative to the sector by 0.35% highlights its leadership within the space. The stock’s large market capitalisation of Rs 1,28,981 crore further underlines its significance in the sector and the broader market.
Investors should note that while the stock is trading above all major moving averages, the recent mojo grade downgrade to Hold signals a need for prudence. The elevated open interest and volume could also imply increased volatility ahead, as market participants adjust their positions in response to evolving fundamentals and technical triggers.

Implications for Investors and Traders
For investors, the current scenario presents a mixed picture. The strong price momentum and rising open interest suggest that the market consensus is bullish in the short term. However, the mojo grade downgrade and the stock’s premium valuation relative to historical averages warrant caution. Investors may consider monitoring key support levels around Rs 4,500 and watch for any signs of profit booking or volatility spikes.
Traders, on the other hand, can capitalise on the heightened liquidity and active derivatives market to implement tactical strategies. The surge in open interest and volume provides ample opportunities for both directional trades and volatility plays, such as spreads or straddles, especially given the stock’s recent volatility and sectoral tailwinds.
Conclusion
Cummins India Ltd’s recent open interest surge in derivatives, coupled with strong price performance and rising volumes, signals increased market participation and bullish sentiment. While the stock continues to outperform its sector and trades above key moving averages, the recent mojo grade downgrade to Hold advises measured optimism. Investors and traders alike should weigh the positive momentum against valuation and technical caution, positioning themselves prudently in this large-cap Compressors, Pumps & Diesel Engines stock.
