Open Interest and Volume Dynamics
On 29 Dec 2025, Tata Steel Ltd’s open interest (OI) in futures and options contracts rose sharply by 9,506 contracts, a 10.37% increase from the previous tally of 91,648 to 101,154. This substantial rise in OI, coupled with a daily volume of 94,782 contracts, indicates heightened trading activity and fresh positions being established by market participants.
The futures value stood at ₹1,37,021.39 lakhs, while the options segment exhibited an enormous notional value of approximately ₹7,84,333.80 crores, reflecting the stock’s significant derivatives market footprint. The combined total derivatives value reached ₹1,45,515.83 lakhs, underscoring the robust liquidity and investor interest in Tata Steel’s contracts.
Price Performance and Technical Indicators
Tata Steel’s underlying price closed at ₹173, having touched an intraday high of ₹174.13, marking a 2.96% gain on the day. This performance outpaced the ferrous metals sector’s 1.48% rise and the Sensex’s marginal decline of 0.14%, highlighting the stock’s relative strength.
Technically, Tata Steel is trading above its key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — signalling a sustained uptrend. The stock’s recent rebound after two consecutive days of decline suggests a potential trend reversal, attracting renewed buying interest.
However, delivery volumes have declined by 23.76% compared to the 5-day average, with 89.71 lakh shares delivered on 26 Dec. This drop in investor participation at the delivery level may indicate that short-term traders and derivatives players are driving the current momentum rather than long-term holders.

Market Positioning and Directional Bets
The surge in open interest alongside rising volumes typically signals fresh directional bets by traders. In Tata Steel’s case, the 10.37% increase in OI suggests that participants are either initiating new long positions or rolling over existing ones, anticipating further price appreciation.
Given the stock’s outperformance relative to its sector and the broader market, it is plausible that bullish sentiment is gaining traction. The stock’s Mojo Score of 77.0 and an upgraded Mojo Grade from Hold to Buy on 9 Dec 2025 further reinforce this positive outlook. The large-cap company, with a market capitalisation of ₹2,16,527 crore, remains a key player in the ferrous metals sector, attracting institutional interest.
Moreover, the stock’s liquidity supports sizeable trade sizes, with an estimated ₹7.43 crore tradable value based on 2% of the 5-day average traded value. This liquidity facilitates active participation by both retail and institutional investors, enabling efficient price discovery and smoother execution of large orders.
Sectoral and Broader Market Context
The ferrous metals sector has shown resilience amid mixed market conditions, with Tata Steel leading gains. The stock’s 2.44% one-day return surpasses the sector’s 1.48% and contrasts with the Sensex’s slight decline, indicating selective buying interest in steel and allied industries.
Global steel demand dynamics, raw material cost trends, and government infrastructure spending remain key drivers for Tata Steel’s fundamentals. The company’s ability to maintain operational efficiencies and capitalise on favourable market conditions will be critical in sustaining its upward momentum.

Implications for Investors
Investors should note the increased open interest as a sign of growing conviction in Tata Steel’s near-term prospects. The stock’s technical strength, combined with its upgraded Mojo Grade to Buy, suggests that it may continue to attract buying interest.
However, the decline in delivery volumes indicates caution, as long-term investor participation has softened. This divergence between derivatives activity and delivery volumes could imply that the current rally is being driven more by speculative or short-term traders rather than fundamental buying.
Given the stock’s large-cap status and sector leadership, it remains a compelling option for investors seeking exposure to the ferrous metals space. Monitoring open interest trends alongside price action and volume will be crucial to gauge the sustainability of the current momentum.
Overall, Tata Steel’s recent derivatives market activity reflects a positive shift in market sentiment, with fresh positions being built amid a favourable technical backdrop and sectoral tailwinds.
Conclusion
The significant rise in open interest and volume in Tata Steel Ltd’s derivatives contracts signals renewed bullish positioning by market participants. Supported by strong price performance, technical strength, and an upgraded Mojo Grade, the stock is poised for potential further gains. Investors should remain attentive to delivery volume trends and broader sector developments to assess the durability of this momentum.
With a market capitalisation exceeding ₹2.16 lakh crore and robust liquidity, Tata Steel continues to be a key focus for both institutional and retail investors in the ferrous metals sector.
