Open Interest and Volume Dynamics
On 23 Feb 2026, UPL's open interest in derivatives jumped from 41,688 contracts to 59,421, marking an increase of 17,733 contracts or 42.54%. This surge in OI was accompanied by a substantial volume of 1,39,985 contracts traded, indicating robust participation from market participants. The futures segment alone accounted for a notional value of approximately ₹2,00,705 lakhs, while options contributed an astronomical ₹11,18,69,00,480, culminating in a total derivatives value exceeding ₹2,18,165 lakhs.
The underlying stock price closed at ₹644, having opened with a gap down of 5%, and touched an intraday low of ₹643.35, representing a steep fall of 14.49% from the previous close. The stock traded within a wide intraday range of ₹71.4, reflecting heightened volatility with an intraday volatility measure of 7.37% based on weighted average price.
Price Performance and Technical Context
UPL has underperformed its sector by 9.37% on the day, with the Pesticides & Agrochemicals sector itself declining by 4.96%. The stock has been on a downward trajectory for two consecutive sessions, losing 15.69% cumulatively. It currently trades below all major moving averages – 5-day, 20-day, 50-day, 100-day, and 200-day – signalling a bearish technical setup. The weighted average price skewed towards the lower end of the day's range, indicating selling pressure dominating the session.
Investor participation has notably increased, with delivery volumes rising by 47.46% to 11.39 lakh shares on 20 Feb 2026 compared to the five-day average. This suggests that despite the price weakness, there is active interest in holding or accumulating shares, possibly by long-term investors or institutional players.
Market Positioning and Directional Bets
The sharp rise in open interest alongside a falling price typically indicates fresh short positions being built or existing longs being unwound. Given the magnitude of the OI increase and the volume spike, it is plausible that traders are positioning for further downside or hedging existing exposures amid uncertainty in the agrochemical sector.
However, the elevated delivery volumes and the stock’s mid-cap market capitalisation of ₹57,116 crore suggest that some investors may view the current weakness as a buying opportunity, especially considering UPL’s fundamental strength and recent upgrade in its Mojo Grade from Hold to Buy on 19 Feb 2026, reflecting improved outlook and confidence in the company’s prospects.

Sectoral and Broader Market Context
The Pesticides & Agrochemicals sector has faced headwinds recently, with a 4.96% decline on the day and ongoing volatility driven by global commodity price fluctuations, regulatory developments, and monsoon forecasts impacting demand expectations. UPL’s underperformance relative to its sector and the broader Sensex, which gained 0.38% on the same day, highlights sector-specific pressures rather than broad market weakness.
Given UPL’s mid-cap status and liquidity profile, with the ability to absorb trades worth ₹2.5 crore based on 2% of the five-day average traded value, the stock remains accessible for both institutional and retail investors. This liquidity supports active derivatives trading and contributes to the observed open interest expansion.
Implications for Investors and Traders
For traders, the surge in open interest combined with falling prices and high volatility suggests caution. The market appears to be pricing in further downside risk or at least uncertainty, making short-term directional bets more pronounced. The elevated options notional value also points to increased hedging activity or speculative positioning, which could amplify price swings in the near term.
Long-term investors should weigh the recent downgrade in price against the company’s upgraded Mojo Grade of 71.0 (Buy) and consider the potential for a rebound once volatility subsides. The increased delivery volumes hint at underlying confidence among some market participants, which may provide a floor to the stock price.

Outlook and Conclusion
UPL Ltd.’s recent derivatives activity reveals a market grappling with uncertainty and positioning for potential further downside amid sectoral challenges. The 42.5% jump in open interest, combined with a 15% drop in share price over two days and high intraday volatility, underscores a cautious sentiment among traders.
Nonetheless, the company’s upgraded Mojo Grade to Buy and rising delivery volumes suggest that some investors remain optimistic about its medium to long-term prospects. For market participants, monitoring open interest trends alongside price action and sector developments will be crucial in gauging the stock’s directional bias going forward.
Given the current technical weakness but fundamental support, a balanced approach is advisable, with traders potentially capitalising on volatility while investors consider accumulation on dips backed by thorough research.
