Open Interest and Volume Dynamics
On 30 Dec 2025, SAIL’s open interest (OI) in derivatives rose sharply by 7,917 contracts, marking a 12.59% increase from the previous day’s 62,897 to 70,814. This surge in OI was accompanied by a robust volume of 60,347 contracts traded, reflecting active participation in the futures and options markets. The futures value stood at ₹1,69,325.37 lakhs, while the options segment contributed a substantial ₹22,592,223,858 lakhs, culminating in a total derivatives value of ₹1,73,024.56 lakhs.
This spike in open interest, coupled with strong volume, typically indicates fresh positions being established rather than existing ones being squared off. Such a pattern often points to directional bets, with market participants positioning themselves for anticipated price movements.
Price Performance and Technical Indicators
SAIL’s underlying stock price closed at ₹139, just 3.52% shy of its 52-week high of ₹145.90. The stock outperformed its sector by 4.74% on the day, registering a 5.11% gain, and has been on a three-day winning streak, delivering a cumulative return of 6.89%. Intraday, the stock touched a high of ₹141.15, representing a 5.27% rise from the previous close.
Technically, SAIL is trading above its key moving averages – 5-day, 20-day, 50-day, 100-day, and 200-day – signalling a strong upward momentum. The weighted average price indicates that more volume was traded near the lower price range of the day, suggesting accumulation by investors at relatively attractive levels.
Investor Participation and Liquidity
Investor participation has notably increased, with delivery volume on 29 Dec reaching 1.37 crore shares, a staggering 167.84% rise compared to the five-day average delivery volume. This surge in delivery volume underscores genuine buying interest rather than speculative trading alone.
Liquidity remains robust, with the stock’s traded value comfortably supporting trade sizes up to ₹5.4 crore based on 2% of the five-day average traded value. This liquidity profile favours institutional investors and large traders looking to build or unwind positions without significant market impact.

Market Positioning and Directional Bets
The sharp rise in open interest alongside increasing volumes suggests that traders are establishing new positions rather than closing existing ones. Given the stock’s recent price appreciation and technical strength, it is plausible that the majority of these positions are bullish bets, anticipating further upside.
Options data further supports this view, with the substantial options value indicating active hedging and speculative activity. The proximity to the 52-week high and the stock’s outperformance relative to the sector and Sensex (which was marginally down by 0.06%) reinforce the notion of positive market sentiment.
Fundamental and Market Context
Steel Authority Of India Ltd., a key player in the ferrous metals industry, currently holds a market capitalisation of ₹55,638 crore, categorising it as a mid-cap stock. The company’s Mojo Score has improved to 58.0, upgrading its Mojo Grade from Sell to Hold as of 23 Dec 2025.

Sectorally, the ferrous metals industry has shown resilience, with SAIL’s 1-day return of 5.41% significantly outpacing the sector’s 0.81% gain. This relative strength highlights SAIL’s leadership within its space and may attract further investor interest.

Implications for Investors
The confluence of rising open interest, strong volume, and positive price action suggests that SAIL is currently in a phase of accumulation by market participants. Investors should note the stock’s technical strength and improving fundamentals, which may support further gains in the near term.
However, the stock remains 3.52% below its 52-week high, indicating some room for upside but also potential resistance ahead. The recent upgrade to a Hold rating from Sell by MarketsMOJO reflects cautious optimism, signalling that while the stock has improved, investors should remain vigilant to sectoral and macroeconomic developments that could impact ferrous metals demand and pricing.
Given the liquidity profile and active derivatives market, institutional investors and traders can efficiently enter or exit positions, but retail investors should consider the stock’s volatility and market context before committing significant capital.
Conclusion
Steel Authority Of India Ltd.’s recent surge in open interest and volume in the derivatives market, combined with its strong price performance and technical indicators, points to a growing bullish consensus among market participants. While fundamentals have improved, the stock’s Hold rating suggests measured optimism. Investors should monitor ongoing market developments and derivative positioning to gauge the sustainability of this momentum.
