Open Interest and Volume Dynamics
The latest data reveals that Zydus Lifesciences’ open interest (OI) in derivatives jumped by 5,031 contracts, a 21.14% increase from the previous tally of 23,796 to 28,827. This substantial rise in OI was accompanied by a volume of 31,588 contracts, indicating robust trading activity. The futures segment alone accounted for a value of approximately ₹19,093.5 lakhs, while options contributed an overwhelming ₹24,901.4 crores in notional value, culminating in a total derivatives value of ₹21,822.7 lakhs.
This surge in open interest, coupled with elevated volumes, suggests that market participants are actively repositioning themselves, possibly anticipating significant price movements in the near term. However, the underlying stock price has shown signs of weakness, trading at ₹902 with an intraday low of ₹896.3, down 2.94% on the day.
Price Performance and Technical Context
Zydus Lifesciences underperformed its Pharmaceuticals & Biotechnology sector by 2.88% and lagged behind the Sensex, which gained 0.36% on the same day. The stock’s one-day return stood at -2.49%, reflecting a bearish undertone. Technically, the share price remains above its 5-day and 20-day moving averages but continues to trade below its 50-day, 100-day, and 200-day moving averages, indicating a mixed trend with resistance at higher levels.
Investor participation has notably increased, with delivery volumes rising to 4.9 lakh shares on 09 Feb 2026, a 68.58% jump compared to the five-day average. This heightened delivery volume suggests that long-term investors are either accumulating or liquidating positions in response to recent price action and market developments.

Market Positioning and Directional Bets
The sharp increase in open interest alongside rising volumes typically signals fresh directional bets or the unwinding of existing positions. In Zydus Lifesciences’ case, the negative price action combined with expanding OI suggests that traders may be building short positions or hedging against downside risks. The futures value of ₹19,093.5 lakhs and the massive options notional value indicate that institutional players are actively engaged in complex strategies, possibly straddles or protective puts, to manage volatility.
Given the stock’s Mojo Score of 48.0 and a recent downgrade from Hold to Sell on 01 Dec 2025, market sentiment appears to be deteriorating. The company’s market cap stands at ₹90,953 crores, categorising it as a mid-cap stock within the Pharmaceuticals & Biotechnology sector. Its market cap grade of 2 further reflects moderate liquidity and investor interest, but not enough to shield it from sectoral headwinds or broader market pressures.
Investors should note that the stock’s liquidity, based on 2% of the five-day average traded value, supports trade sizes up to ₹1.73 crores, making it accessible for institutional and retail participants alike. However, the current technical and fundamental signals caution against aggressive long positions.

Implications for Investors
The confluence of rising open interest, increased volumes, and declining prices in Zydus Lifesciences suggests a cautious stance among derivatives traders. The market appears to be pricing in potential near-term weakness, possibly due to sector-specific challenges or company-specific concerns. Investors should closely monitor upcoming quarterly results, regulatory developments, and sectoral trends that could influence the stock’s trajectory.
Moreover, the downgrade to a Sell rating by MarketsMOJO, reflecting a Mojo Grade decline from Hold, underscores the need for prudence. While the company’s fundamentals remain solid in the long term, the current technical setup and market positioning indicate a period of consolidation or correction.
For traders, the elevated open interest and volume provide opportunities to capitalise on volatility through options strategies, but risk management remains paramount given the stock’s recent underperformance relative to its sector and benchmark indices.
Sector and Market Context
The Pharmaceuticals & Biotechnology sector has shown resilience but faces headwinds from regulatory scrutiny and pricing pressures. Zydus Lifesciences, as a mid-cap player with a market cap nearing ₹91,000 crores, is navigating these challenges amid evolving investor sentiment. The stock’s relative underperformance compared to the sector’s 0.42% gain and Sensex’s 0.36% rise on the day highlights selective profit-taking or rotation within the space.
Investors should weigh these factors alongside the company’s delivery volume spike of 68.58% over the five-day average, which may indicate institutional repositioning ahead of strategic announcements or earnings releases.
Conclusion
Zydus Lifesciences Ltd’s recent surge in open interest and trading volumes in the derivatives market signals active repositioning by investors amid a backdrop of price weakness and a downgrade in sentiment. While the company’s fundamentals remain intact, the technical indicators and market positioning suggest caution. Investors and traders should monitor developments closely and consider the broader sector dynamics before making directional bets.
