Robust Call Option Volumes Signal Investor Confidence
On 7 January 2026, Sun Pharma’s call options with a strike price of ₹1800 expiring on 27 January recorded an impressive 9,904 contracts traded, generating a turnover of ₹867.29 lakhs. This volume represents a significant concentration of bullish bets, especially considering the underlying stock closed at ₹1785.30, just ₹14.70 shy of the strike price. The open interest for these contracts stands at 3,449, indicating sustained investor interest and potential for further price movement towards or beyond the strike level.
The high turnover and open interest in these call options suggest that market participants are positioning for a potential upside in the near term. This is further supported by the stock’s recent price action, which has seen a consistent upward trajectory over the past five trading sessions, delivering a cumulative return of 4.06% during this period.
Price Performance and Technical Strength
Sun Pharma’s stock price has been resilient, outperforming its sector by 0.57% on the day of analysis and closing just 4.22% below its 52-week high of ₹1865. The stock touched an intraday high of ₹1806.60, marking a 2.64% gain on the day. Notably, the share price is trading above all key moving averages – 5-day, 20-day, 50-day, 100-day, and 200-day – underscoring a strong technical setup that favours further gains.
Despite a slight dip in delivery volume by 6.65% compared to the five-day average, the stock remains liquid enough to support sizeable trades, with an average traded value sufficient for transactions up to ₹4.6 crores. This liquidity ensures that the stock can absorb increased demand without significant price disruption, a positive sign for option traders and equity investors alike.
Fundamental Backdrop and Market Positioning
Sun Pharmaceutical Industries Ltd, a large-cap entity with a market capitalisation of ₹4,22,523 crores, operates within the Pharmaceuticals & Biotechnology sector. The company holds a Mojo Score of 72.0 and currently carries a ‘Buy’ Mojo Grade, recently downgraded from ‘Strong Buy’ on 16 December 2025. This slight moderation in rating reflects a cautious but optimistic outlook, balancing solid fundamentals with near-term market uncertainties.
The company’s strong market position, diversified product portfolio, and ongoing innovation pipeline continue to underpin investor confidence. The recent call option activity aligns with this narrative, as traders appear to be anticipating positive catalysts or sustained momentum that could propel the stock price beyond the ₹1800 strike level before expiry.

Expiry Patterns and Strategic Implications
The expiry date of 27 January 2026 is a critical juncture for option traders, as it marks the deadline for exercising or closing positions. The concentration of call option activity at the ₹1800 strike price suggests that investors are betting on the stock crossing this threshold within the next three weeks. Given the current price of ₹1785.30 and the recent upward momentum, this target appears achievable, albeit with some volatility expected.
Options traders often use such strike prices as psychological resistance or support levels. The heavy open interest at ₹1800 could act as a magnet, drawing the stock price towards it as expiry approaches. Should the stock breach this level convincingly, it may trigger further buying interest, both in the options and underlying shares, potentially driving prices higher.
Sectoral Context and Comparative Performance
Within the Pharmaceuticals & Biotechnology sector, Sun Pharma’s outperformance is notable. The sector recorded a 1-day return of 0.98%, while the broader Sensex declined by 0.15% on the same day. This relative strength highlights the stock’s defensive qualities and investor preference amid mixed market conditions.
Sun Pharma’s ability to maintain gains above multiple moving averages and near its 52-week high reinforces its status as a sector leader. Investors looking for exposure to the pharmaceutical space may find the current option activity a useful barometer of market sentiment and potential price direction.

Investor Takeaway and Outlook
For investors and traders, the current call option activity in Sun Pharmaceutical Industries Ltd offers valuable insight into market expectations. The heavy volume and open interest at the ₹1800 strike price, combined with the stock’s technical strength and sector outperformance, suggest a bullish bias heading into the January expiry.
However, the recent downgrade from ‘Strong Buy’ to ‘Buy’ Mojo Grade signals that while the fundamentals remain solid, investors should remain vigilant for potential volatility or sector-specific headwinds. The falling delivery volume hints at some caution among long-term holders, even as short-term traders ramp up bullish positions.
Overall, the data points to a scenario where Sun Pharma could test and possibly surpass the ₹1800 level in the coming weeks, driven by positive sentiment and sustained buying interest. Market participants should monitor price action closely, especially around key technical levels and expiry dates, to capitalise on potential opportunities.
