Open Interest Spike and Volume Dynamics
On 26 Feb 2026, Fortis Healthcare’s open interest (OI) in derivatives rose sharply by 2,990 contracts, a 17.81% increase from the previous day’s 16,789 to 19,779. This notable expansion in OI was accompanied by a volume of 18,668 contracts, underscoring active trading interest. The futures segment alone accounted for a value of approximately ₹21,101 lakhs, while options contributed a substantial ₹12,139.66 crores, culminating in a total derivatives value of ₹24,394.53 lakhs.
The underlying stock price closed at ₹954, having touched an intraday high of ₹961.4, marking a 3.29% gain on the day. This price action, coupled with the OI increase, suggests that market participants are positioning for further upside, supported by strong liquidity and rising investor participation.
Market Positioning and Directional Bets
The surge in open interest alongside rising volume typically indicates fresh capital entering the market rather than mere position squaring. In Fortis Healthcare’s case, the 17.81% jump in OI, combined with a 2.15% day change in price, points to bullish sentiment among traders and investors. The stock has been on a two-day consecutive gain streak, delivering a 3.75% return over this period, outperforming the hospital sector by 2.07% and the Sensex by over 2.2 percentage points.
Further reinforcing this positive outlook is the stock’s trading above all key moving averages—5-day, 20-day, 50-day, 100-day, and 200-day—indicating a strong technical uptrend. The delivery volume on 25 Feb surged to 11.05 lakh shares, a remarkable 116.75% increase over the five-day average, signalling rising investor conviction and accumulation.

Investor Sentiment and Technical Outlook
Fortis Healthcare’s Mojo Score currently stands at 51.0 with a Mojo Grade of Hold, reflecting a cautious stance despite recent bullish momentum. This represents a downgrade from a Buy rating on 13 Jan 2025, signalling that while the stock shows strength, certain risks or valuation concerns temper enthusiasm. The company’s market capitalisation is ₹71,834 crores, placing it firmly in the mid-cap segment with a Market Cap Grade of 2.
The stock’s liquidity profile supports sizeable trades, with the average traded value over five days allowing for a trade size of approximately ₹2.21 crores based on 2% of average volume. This liquidity ensures that institutional investors can enter or exit positions without significant price disruption, further encouraging participation.
Sector and Broader Market Context
Within the hospital sector, Fortis Healthcare’s outperformance is notable. The sector recorded a modest 0.11% gain on the day, while the Sensex declined marginally by 0.06%. This divergence highlights Fortis’s relative strength amid a mixed market environment. The hospital industry continues to attract investor interest due to structural growth drivers such as rising healthcare demand, increasing insurance penetration, and expanding infrastructure.
However, the downgrade in Mojo Grade suggests investors should remain vigilant about potential headwinds, including regulatory changes, competitive pressures, and margin fluctuations. The recent open interest surge may also reflect speculative positioning, which can lead to increased volatility in the near term.

Implications for Investors
The sharp rise in open interest and volume in Fortis Healthcare’s derivatives market suggests that traders are increasingly positioning for a directional move, likely to the upside given the concurrent price gains and technical strength. This could be driven by expectations of positive earnings, strategic initiatives, or sector tailwinds.
Investors should monitor the sustainability of this momentum, paying close attention to changes in delivery volumes, price action relative to moving averages, and any shifts in the Mojo Grade or analyst ratings. The current Hold rating advises a balanced approach, favouring accumulation on dips rather than aggressive buying at elevated levels.
Moreover, the liquidity profile and market cap grade indicate that Fortis Healthcare remains accessible for both retail and institutional investors, supporting continued market participation and price discovery.
Conclusion
Fortis Healthcare Ltd’s recent open interest surge in derivatives, combined with strong volume and price performance, signals growing investor confidence and potential bullish positioning. While the stock has outperformed its sector and broader market indices, the downgrade to a Hold rating and moderate Mojo Score counsel prudence. Investors should weigh the positive technical signals against valuation and sector risks, maintaining a watchful eye on evolving market dynamics.
Overall, Fortis Healthcare remains a key mid-cap player in the hospital sector, attracting attention from diverse market participants amid a backdrop of rising healthcare demand and improving fundamentals.
