Open Interest and Volume Dynamics
The open interest in UPL’s derivatives jumped from 41,688 contracts to 66,999 contracts, an increase of 25,311 contracts or 60.72% on 23 Feb 2026. This surge in OI was accompanied by a substantial volume of 2,07,202 contracts traded, reflecting intense activity in both futures and options markets. The futures segment alone accounted for a value of approximately ₹3,03,050 lakhs, while options contributed an astronomical ₹16,24,59,508,993 lakhs in notional value, underscoring the scale of derivative trading interest.
The underlying stock price closed at ₹641, having experienced a steep intraday fall to a low of ₹625.55, down 16.85% from the previous close. The stock opened with a gap down of 5%, trading in a wide range of ₹89.2, and exhibited high intraday volatility of 9.05%, calculated from the weighted average price. Notably, the weighted average price skewed towards the lower end of the day’s range, indicating selling pressure throughout the session.
Price Performance and Sector Context
UPL underperformed its sector, which itself declined by 4.94%, with the stock falling 14.79% on the day. This underperformance extended a two-day losing streak, during which UPL’s share price has dropped 16.3%. The stock is trading below all key moving averages – 5-day, 20-day, 50-day, 100-day, and 200-day – signalling a bearish technical setup. Despite the sharp price fall, delivery volumes rose sharply by 47.46% compared to the five-day average, with 11.39 lakh shares delivered on 20 Feb 2026, suggesting rising investor participation amid the sell-off.

Market Positioning and Directional Bets
The sharp rise in open interest amid falling prices suggests that market participants are actively repositioning, possibly increasing bearish bets or hedging existing long exposures. The combination of rising OI and declining price typically indicates fresh short positions being initiated rather than short covering. This is further supported by the heavy volume traded near the day’s low, implying aggressive selling pressure.
Options market activity, given the enormous notional value, points to complex strategies being employed, including protective puts or bearish spreads. The large increase in OI could also reflect institutional players adjusting their portfolios in response to sectoral headwinds or company-specific concerns. UPL’s mid-cap market capitalisation of ₹54,115.17 crores and a Mojo Score of 71.0, upgraded recently from Hold to Buy on 19 Feb 2026, add an interesting dimension to the current price action, as the fundamental outlook remains positive despite near-term volatility.
Technical and Fundamental Outlook
Technically, UPL’s breach below multiple moving averages and the high volatility environment suggest caution for short-term traders. However, the recent upgrade in Mojo Grade from Hold to Buy reflects improving fundamentals and positive medium-term prospects in the agrochemical sector. The stock’s liquidity profile remains robust, with the ability to absorb trades worth ₹2.5 crores based on 2% of the five-day average traded value, ensuring smooth execution for institutional investors.
Investors should closely monitor the evolution of open interest and volume patterns in the coming sessions to gauge whether the current selling pressure is a transient correction or the start of a deeper downtrend. The sector’s modest decline relative to UPL’s sharper fall may indicate company-specific factors at play, warranting a thorough fundamental review alongside technical analysis.

Implications for Investors
For investors, the current scenario presents a mixed picture. The fundamental upgrade and strong Mojo Score suggest that UPL remains a Buy on a medium-term horizon. However, the sharp increase in open interest coupled with a steep price decline and high volatility signals caution in the near term. Traders may consider waiting for confirmation of a trend reversal or further clarity in market positioning before initiating fresh long positions.
Meanwhile, the elevated delivery volumes indicate that some investors are accumulating shares despite the price weakness, possibly anticipating a rebound. The divergence between rising open interest and falling prices also highlights the importance of monitoring derivative market data as a complementary tool to price action for better timing and risk management.
Conclusion
UPL Ltd.’s recent surge in open interest amid volatile trading underscores a significant shift in market sentiment and positioning. While the stock faces short-term headwinds reflected in its price action and technical indicators, the fundamental outlook remains constructive as per recent upgrades. Investors should adopt a balanced approach, leveraging derivative market insights alongside fundamental and technical analysis to navigate the evolving landscape in this key agrochemical stock.
