Zydus Lifesciences Sees Sharp Open Interest Surge Amid Bullish Market Positioning

Open Interest and Volume Dynamics

The latest data reveals that Zydus Lifesciences’ open interest increased by 2,687 contracts from the previous 15,128, marking a substantial 17.76% rise. This surge in OI was matched by a volume of 24,322 contracts, indicating strong participation in the derivatives market. The futures segment alone accounted for a notional value of approximately ₹24,561 lakhs, while the options segment’s value was significantly higher at ₹18,664 crores, culminating in a total derivatives value of ₹28,279 lakhs.

Such a pronounced increase in open interest alongside elevated volume typically reflects fresh positions being established rather than existing ones being squared off. This suggests that market participants are actively positioning themselves, potentially anticipating a directional move in the underlying stock.

Price Performance and Technical Context

Zydus Lifesciences has outperformed its Pharmaceuticals & Biotechnology sector by 1.32% on the day, with a 1-day return of 1.78% compared to the sector’s 0.27% and the Sensex’s marginal decline of 0.18%. The stock has gained for two consecutive sessions, delivering a cumulative return of 3.44% over this period. Intraday, it touched a high of ₹947.55, up 3.03% from the previous close, signalling bullish momentum.

Technically, the stock is trading above its 5-day, 20-day, 50-day, and 100-day moving averages, though it remains below the 200-day moving average. This positioning indicates short- to medium-term strength, while the longer-term trend remains under watch. Notably, delivery volumes surged to 3.51 lakh shares on 25 Feb, a 104.92% increase over the 5-day average, reflecting rising investor participation and conviction.

Market Capitalisation and Analyst Ratings

Zydus Lifesciences is classified as a mid-cap company with a market capitalisation of ₹93,600 crores. Despite the recent price gains and increased activity, the stock’s Mojo Score currently stands at 48.0, with a Mojo Grade of Sell, downgraded from Hold as of 1 Dec 2025. The market cap grade is 2, indicating moderate liquidity and market interest but caution from analysts regarding near-term prospects.

The downgrade reflects concerns over valuation pressures and competitive challenges within the Pharmaceuticals & Biotechnology sector, despite the company’s solid fundamentals and pipeline. Investors should weigh these factors carefully when interpreting the surge in derivatives activity.

Interpreting the Open Interest Surge: Directional Bets and Market Positioning

The sharp rise in open interest, coupled with increasing volumes and positive price action, suggests that traders are building fresh positions with a bullish bias. The underlying value of the stock at ₹934 supports this view, as the stock’s recent highs near ₹947.55 indicate confidence in further upside potential.

Options market data, with an enormous notional value of ₹18,664 crores, points to active call option buying or put option selling, both of which are bullish strategies. This heightened activity in options could be driven by institutional investors or hedge funds positioning for anticipated catalysts such as earnings announcements, regulatory approvals, or sector tailwinds.

Moreover, the increase in delivery volumes by over 100% compared to the recent average highlights genuine investor interest beyond speculative trading, reinforcing the notion of a sustained uptrend.

Sectoral and Broader Market Context

The Pharmaceuticals & Biotechnology sector has been under pressure in recent months due to regulatory scrutiny and pricing challenges. However, Zydus Lifesciences’ outperformance relative to its peers and the broader Sensex suggests it is bucking the trend, possibly due to a robust product pipeline or strategic initiatives.

Investors should note that while the stock is showing signs of strength, the downgrade to a Sell rating by MarketsMOJO indicates caution. The Mojo Score of 48.0 reflects a middling outlook, suggesting that while short-term momentum is positive, risks remain in the medium term.

Investor Takeaways and Outlook

For investors and traders, the recent surge in open interest and volume in Zydus Lifesciences’ derivatives market signals an important shift in market positioning. The data suggests a growing consensus on potential upside, supported by technical strength and rising delivery volumes.

However, the downgrade to a Sell rating and a modest Mojo Score counsel prudence. Investors should monitor upcoming quarterly results, regulatory developments, and sector dynamics closely before committing fresh capital. The stock’s liquidity, with a trade size capacity of nearly ₹1 crore based on 2% of the 5-day average traded value, ensures ease of entry and exit for institutional players.

In summary, while the derivatives market activity points to bullish sentiment, the broader fundamental and technical context advises a balanced approach. Investors may consider phased buying or hedged positions to capitalise on potential gains while managing downside risks.
