Fortis Healthcare Sees Sharp Open Interest Surge Amid Bullish Derivatives Activity

Open Interest and Volume Dynamics

The latest data reveals that Fortis Healthcare’s open interest (OI) in derivatives rose from 24,057 contracts to 28,433, an increase of 4,376 contracts or 18.19% on 19 Feb 2026. This surge accompanies a daily volume of 21,395 contracts, indicating robust trading activity. The futures segment alone accounted for a notional value of approximately ₹81,555 lakhs, while options contributed a staggering ₹7,218.7 crores, culminating in a total derivatives value exceeding ₹82,262 lakhs.

This spike in OI, coupled with strong volume, typically reflects fresh positions being established rather than existing ones being squared off. Market participants appear to be actively repositioning, possibly in anticipation of upcoming corporate developments or sectoral shifts within the hospital industry.

Price Performance and Moving Averages

Fortis Healthcare’s stock price closed at ₹922, touching an intraday high of ₹926.9, up 2.24% on the day and outperforming its hospital sector peers by 1%. The stock’s 1-day return of 1.61% also surpassed the Sensex’s 0.62% gain, signalling relative strength. Technical indicators show the price trading above its 5-day, 20-day, 50-day, and 200-day moving averages, though it remains below the 100-day moving average, suggesting a mixed medium-term trend.

However, investor participation appears to be waning, with delivery volumes dropping by 55.46% compared to the 5-day average, indicating that while speculative activity in derivatives is rising, long-term holding interest may be diminishing.

Market Positioning and Directional Bets

The sharp increase in open interest alongside rising volumes often points to directional bets being placed by traders. Given the stock’s outperformance and positive price momentum, it is plausible that a significant portion of the new positions are bullish, anticipating further upside. Yet, the decline in delivery volumes and the stock’s inability to breach the 100-day moving average suggest some caution among institutional investors.

Options market data, with a notional value exceeding ₹7,218 crores, indicates active hedging and speculative strategies. The large options value relative to futures suggests that traders may be using options to express nuanced views, such as protective puts or call spreads, rather than outright directional exposure.

Mojo Score and Analyst Ratings

Fortis Healthcare currently holds a Mojo Score of 51.0, placing it in the 'Hold' category, a downgrade from its previous 'Buy' rating as of 13 Jan 2025. The market cap grade stands at 2, reflecting its mid-cap status with a valuation of approximately ₹69,547 crores. This rating adjustment signals a more cautious stance from analysts, likely influenced by the mixed technical signals and fluctuating investor participation.

While the hospital sector remains a critical defensive play amid ongoing healthcare demand, Fortis’s recent performance and derivative market activity suggest investors are weighing near-term risks against longer-term growth prospects.

Liquidity and Trading Considerations

Liquidity metrics indicate that Fortis Healthcare is sufficiently liquid for sizeable trades, with the stock’s traded value representing about 2% of its 5-day average, enabling trade sizes of up to ₹2.11 crores without significant market impact. This liquidity supports active derivative trading and facilitates efficient price discovery.

However, the sharp fall in delivery volumes to 2.97 lakh shares on 19 Feb, down over 55% from the recent average, suggests that while speculative interest is rising, genuine investor conviction may be subdued. This divergence between derivatives activity and cash market participation warrants close monitoring.

Sector and Market Context

The hospital sector has shown moderate gains, with Fortis outperforming the sector’s 0.64% daily return. This relative strength may be driven by company-specific factors such as operational improvements, expansion plans, or positive earnings outlooks. Nonetheless, broader market conditions, including macroeconomic factors and regulatory developments, continue to influence investor sentiment.

Given the sector’s defensive characteristics, Fortis’s derivative market activity could be reflecting hedging strategies by institutional investors seeking to manage risk amid uncertain market conditions.

Outlook and Investor Takeaways

Fortis Healthcare’s recent surge in open interest and volume in the derivatives market highlights a period of active repositioning by traders. The stock’s outperformance relative to its sector and the broader Sensex, combined with its technical positioning above key short-term moving averages, suggests a cautiously optimistic outlook.

However, the decline in delivery volumes and the Mojo Score downgrade to 'Hold' indicate that investors should remain vigilant. The mixed signals imply that while there is potential for further gains, risks related to market volatility, sector-specific challenges, and valuation concerns persist.

Investors may consider monitoring derivative market trends closely, particularly changes in put-call ratios and strike price concentrations, to gauge evolving sentiment. Additionally, balancing exposure with other healthcare stocks or sectors could help mitigate risk amid uncertain market conditions.

Conclusion

The sharp increase in Fortis Healthcare’s open interest reflects a dynamic market environment where traders are actively adjusting positions in anticipation of future moves. While the stock shows relative strength and liquidity remains adequate, the mixed technical and fundamental signals counsel a measured approach. Investors should weigh the potential rewards against the inherent risks and consider derivative market insights as part of a comprehensive investment strategy.
