Open Interest and Volume Dynamics
On 29 Dec 2025, Tata Steel Ltd’s open interest (OI) in derivatives rose sharply to 1,07,161 contracts, up 15,513 contracts or 16.93% from the previous 91,648. This substantial increase in OI was accompanied by a high trading volume of 1,69,542 contracts, reflecting heightened activity in both futures and options segments. The futures value stood at ₹2,70,757.86 lakhs, while the options value was an enormous ₹13,73,89,64,600 lakhs, culminating in a total derivatives value of ₹2,84,673.81 lakhs. Such figures underscore the growing interest among traders and institutional participants in Tata Steel’s price movements.
Price Performance and Market Context
Tata Steel’s underlying share price closed at ₹171, having touched an intraday high of ₹174.13, marking a 2.96% gain on the day. This performance outpaced the ferrous metals sector, which rose by 0.67%, and the Sensex, which declined by 0.41%. The stock’s 1-day return was 1.60%, further highlighting its relative strength. Notably, Tata Steel reversed a two-day losing streak, signalling a potential trend reversal supported by fresh buying interest.
The stock’s price remains above its 5-day, 20-day, 100-day, and 200-day moving averages, though it is still trading below the 50-day moving average. This technical positioning suggests a mixed but cautiously optimistic outlook, with short-term momentum gaining but medium-term resistance yet to be overcome.
Investor Participation and Liquidity Considerations
Despite the surge in derivatives activity, delivery volumes have declined. On 26 Dec 2025, delivery volume was 89.71 lakh shares, down 23.76% compared to the 5-day average. This falling investor participation in the cash segment may indicate that traders are increasingly favouring derivatives for directional exposure rather than outright stock accumulation. However, liquidity remains robust, with the stock’s average traded value supporting trade sizes up to ₹7.43 crore, ensuring ease of entry and exit for large positions.

Market Positioning and Directional Bets
The sharp rise in open interest alongside strong volume suggests that market participants are positioning for a directional move in Tata Steel’s shares. The increase in OI by nearly 17% indicates fresh contracts being added rather than existing ones being squared off, which typically points to new bets being placed. Given the stock’s recent price rebound and outperformance, it is plausible that traders are leaning towards bullish strategies, anticipating further upside.
Options data, with an exceptionally high notional value, also hints at complex positioning, including hedging and speculative plays. The large options value relative to futures suggests active call and put writing and buying, which can be indicative of volatility expectations or strategic directional plays. The stock’s current price near ₹171, coupled with its technical setup, may be attracting call buyers betting on a breakout above the 50-day moving average resistance.
Fundamental and Rating Update
Tata Steel Ltd, a heavyweight in the ferrous metals sector with a market capitalisation of ₹2,14,491.96 crore, has recently seen its Mojo Grade upgraded from Hold to Buy on 9 Dec 2025, reflecting improved fundamentals and positive outlook.

Implications for Investors
The surge in derivatives open interest combined with positive price momentum and a recent rating upgrade suggests that Tata Steel Ltd is attracting renewed investor interest. Traders and investors should monitor the stock’s ability to sustain gains above key moving averages, particularly the 50-day average, which currently acts as resistance.
Given the large derivatives volumes and open interest, volatility may increase in the near term, offering opportunities for both directional and hedging strategies. Investors with a bullish outlook may consider accumulating on dips, while cautious participants should watch for any signs of profit-taking or reversal, especially if delivery volumes continue to decline.
Sector and Market Outlook
The ferrous metals sector remains sensitive to global commodity prices, demand from infrastructure and automotive industries, and domestic economic policies. Tata Steel’s strong market position and recent operational improvements position it well to capitalise on sectoral recovery. However, external risks such as raw material cost inflation and geopolitical tensions could impact near-term performance.
Overall, the current market positioning and derivatives activity reflect a cautiously optimistic stance among investors, with Tata Steel Ltd emerging as a key stock to watch in the ferrous metals space.
