Open Interest and Volume Dynamics
On 20 Apr 2026, Torrent Power’s open interest (OI) in derivatives rose sharply by 3,595 contracts, a 29.99% increase from the previous figure of 11,986 to 15,581. This substantial uptick in OI is accompanied by a high trading volume of 36,239 contracts, reflecting active participation in both futures and options segments. The futures value stood at ₹15,797.57 lakhs, while the options segment exhibited an enormous notional value of approximately ₹23,551.69 crores, culminating in a total derivatives value of ₹19,742.84 lakhs.
This surge in open interest, combined with elevated volumes, typically indicates fresh capital inflows and new directional bets being placed by market participants. It suggests that traders are positioning themselves for continued price movement rather than merely unwinding existing positions.

Market Positioning and Directional Bets
The sharp rise in open interest alongside increasing volumes suggests that market participants are taking fresh positions, likely anticipating further upside in Torrent Power’s shares. The stock’s mojo score has been upgraded from Hold to Buy on 17 Apr 2026, with a current score of 70.0, reflecting improved fundamentals and technical outlook. This upgrade signals growing confidence among analysts and investors in the company’s prospects.
Given the stock’s mid-cap status with a market capitalisation of ₹80,927 crores, the liquidity profile remains robust, supporting sizeable trade sizes up to ₹1.77 crores based on 2% of the 5-day average traded value. This liquidity ensures that institutional investors can enter or exit positions without significant price impact, which is crucial for sustained momentum.
Investors should note that the underlying value of Torrent Power shares stands at ₹1,620, with the current price exceeding this level, indicating a premium that reflects positive market sentiment. The consistent gains over six sessions and the new 52-week high reinforce the likelihood of continued bullish positioning in the near term.
