On 16 Feb 2026, Torrent Pharmaceuticals Ltd. (symbol: TORNTPHARM) recorded a notable increase in open interest (OI) in its futures and options contracts. The latest OI stood at 25,422 contracts, up from 20,437 contracts previously, marking a substantial 24.39% rise. This jump in OI was accompanied by a trading volume of 1,07,182 contracts, indicating heightened investor activity and interest in the stock’s derivatives.
The combined futures and options value reached an impressive ₹79,041.06 lakhs, with futures alone accounting for ₹61,133.99 lakhs.

Price Performance and Technical Strength
Torrent Pharma’s price momentum has been robust, with the stock gaining for three consecutive sessions and delivering a cumulative return of 5.82% over this period. The stock’s current price comfortably trades above all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — signalling strong technical support and a sustained uptrend.
Investor participation has also intensified, as evidenced by a 27.9% rise in delivery volume to 2.21 lakh shares on 13 Feb compared to the five-day average. This increase in delivery volume suggests genuine accumulation rather than speculative trading, reinforcing the bullish narrative.
Market Positioning and Directional Bets
The sharp rise in open interest alongside elevated volumes typically indicates fresh capital entering the market, often reflecting directional bets. In the case of Torrent Pharmaceuticals, the 24.39% increase in OI suggests that traders are positioning for further upside, supported by the stock’s recent price strength and sectoral tailwinds.
Given the stock’s large-cap status with a market capitalisation of ₹1,45,550 crore and a strong Mojo Score of 77.0, upgraded from Hold to Buy on 23 Dec 2025, the market appears confident in its fundamentals and growth prospects. The Mojo Grade upgrade underscores improved financial metrics and positive earnings outlook, which likely underpin the increased derivatives activity.
