Open Interest Spike and Volume Dynamics
On 20 Feb 2026, Grasim Industries recorded an open interest of 89,977 contracts, marking an 11.92% increase from the previous day’s 80,393 contracts. This rise of 9,584 contracts is significant, especially when juxtaposed with the daily traded volume of 35,713 contracts. The increase in OI alongside robust volume suggests fresh positions are being established rather than existing ones being squared off, indicating a strong directional conviction among market participants.
The futures value stood at approximately ₹1,61,480.69 lakhs, while the options segment exhibited an enormous notional value of ₹9,459.72 crores, underscoring the stock’s prominence in the derivatives market. The combined total derivatives value reached ₹1,61,991.30 lakhs, reflecting substantial liquidity and active participation.
Price Action and Moving Averages Context
Despite the surge in derivatives activity, Grasim’s underlying price closed at ₹2,851, which is 4.56% shy of its 52-week high of ₹2,979. The stock has underperformed its sector by 0.76% on the day and has declined by 2.89% over the past two sessions, marking a consecutive fall. Notably, the price remains above its 50-day, 100-day, and 200-day moving averages, signalling a longer-term uptrend, but is currently trading below its 5-day and 20-day moving averages, indicating short-term weakness or consolidation.
Investor participation appears to be waning, with delivery volumes on 19 Feb falling by 15.55% to 1.91 lakh shares compared to the five-day average. This decline in delivery volume suggests that while derivatives activity is heating up, actual shareholding changes are more muted, possibly reflecting speculative positioning rather than fundamental buying or selling.

Market Positioning and Potential Directional Bets
The sharp increase in open interest, coupled with steady volume, points to a growing interest in Grasim’s derivatives as traders position for potential price moves. Given the recent price softness and the stock’s proximity to its 52-week high, market participants may be hedging or speculating on a near-term correction or consolidation phase.
Options data, with a notional value exceeding ₹9,459 crores, suggests significant activity in both calls and puts, though the exact skew is not disclosed here. This level of options engagement often indicates that traders are employing complex strategies such as spreads or straddles to capitalise on expected volatility or directional shifts.
Grasim’s Mojo Score of 78.0 and an upgraded Mojo Grade from Hold to Buy as of 19 Jan 2026 reflect improving fundamentals and positive analyst sentiment. The stock’s large market capitalisation of ₹1,93,880.82 crores further supports its status as a key sector bellwether, attracting institutional interest and contributing to its liquidity profile.
Sector and Benchmark Comparison
On the day, Grasim’s 1-day return was -0.53%, underperforming the Cement & Cement Products sector’s 0.30% gain and the Sensex’s 0.42% rise. This relative weakness amid broader market strength may be a factor driving the increased derivatives activity, as traders seek to hedge or speculate on potential sector rotation or stock-specific developments.
The stock’s liquidity, assessed at 2% of the five-day average traded value, supports trade sizes up to ₹2.24 crores, making it accessible for both retail and institutional traders to execute sizeable positions without significant market impact.

Implications for Investors and Traders
The current derivatives market activity in Grasim Industries suggests a nuanced outlook. The increase in open interest and volume points to fresh bets being placed, possibly anticipating volatility or a directional move. However, the short-term price weakness and falling delivery volumes caution against overly bullish assumptions.
Investors should monitor the stock’s price action relative to its short-term moving averages and watch for any shifts in open interest patterns, particularly in options strikes, to gauge market sentiment more precisely. The upgraded Mojo Grade to Buy and a strong Mojo Score provide a fundamental backdrop that supports a positive medium-term view, but near-term volatility remains a possibility.
Given the stock’s large-cap status and sector leadership, institutional flows and macroeconomic factors affecting the cement industry will continue to influence Grasim’s trajectory. Traders might consider strategies that balance risk and reward, such as protective puts or spread trades, to navigate the current environment.
Conclusion
Grasim Industries Ltd’s recent surge in open interest and sustained volume in derivatives markets highlight increased market engagement amid a backdrop of mixed price signals. While the stock remains fundamentally strong with an upgraded rating and solid market capitalisation, short-term price softness and declining delivery volumes suggest caution. Investors and traders should closely analyse evolving positioning and technical indicators to capitalise on potential opportunities while managing risk prudently.
