Open Interest and Volume Dynamics
On 25 Aug 2026, SAIL’s open interest (OI) in derivatives rose sharply by 7,953 contracts, marking a 16.34% increase from the previous OI of 48,671 to 56,624. This substantial rise in OI, coupled with a daily volume of 90,124 contracts, indicates heightened trader engagement and fresh positions being established rather than mere unwinding of existing ones.
The futures segment alone accounted for a value of approximately ₹4,19,654 lakhs, while the options segment’s value was significantly larger at ₹3,70,997.7 crores, culminating in a total derivatives value of ₹4,26,582.3 lakhs. This robust activity underscores the growing interest in SAIL’s price movements among institutional and retail participants alike.
Price Performance and Market Positioning
SAIL’s underlying stock price closed at ₹186, having opened with a gap-up of 3.7% and touched an intraday high of ₹186.3. The stock outperformed its ferrous metals sector by 4.12% and the Sensex by 3.37%, reflecting strong buying momentum. Notably, SAIL has gained 7.35% over the past two consecutive trading sessions, signalling sustained bullishness.
The stock is trading above all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — which is a technical endorsement of its upward trend. Additionally, delivery volumes surged to 2.31 crore shares on 24 Aug, a remarkable 306.93% increase over the five-day average, indicating rising investor conviction and participation in the underlying equity.
Implications of Rising Open Interest
The sharp increase in open interest alongside rising prices typically suggests fresh long positions being built, pointing to a bullish market stance. Traders appear to be positioning for further upside in SAIL, possibly anticipating positive sectoral developments or company-specific catalysts. The narrow intraday trading range of ₹0.12 on the day of the surge hints at controlled volatility, which often precedes a decisive directional move.
Given the mid-cap status of SAIL with a market capitalisation of ₹75,589 crore, the stock offers ample liquidity and scope for sizeable trades, as evidenced by the ability to handle trade sizes up to ₹7.33 crore based on 2% of the five-day average traded value. This liquidity is crucial for institutional investors looking to establish or adjust positions without significant price impact.

Mojo Score Upgrade and Analyst Sentiment
Reflecting the positive momentum, MarketsMOJO has upgraded SAIL’s Mojo Grade from Hold to Buy as of 23 Dec 2025, with a Mojo Score of 70.0. This upgrade signals improved fundamentals and technical outlook, reinforcing the stock’s attractiveness for investors seeking exposure to the ferrous metals sector.
The upgrade aligns with the recent price action and derivatives market activity, suggesting that both fundamental and technical factors are converging to support a bullish stance. The stock’s outperformance relative to its sector and benchmark indices further validates this positive assessment.
Sectoral Context and Broader Market Trends
The ferrous metals sector has been under pressure in recent months due to global supply chain concerns and fluctuating commodity prices. However, SAIL’s recent gains and rising open interest indicate a potential turnaround or sector rotation favouring select players with strong balance sheets and operational efficiencies.
Investors are likely positioning for a recovery in steel demand, possibly driven by infrastructure spending and industrial activity. SAIL’s mid-cap status and liquidity make it a preferred choice for traders looking to capitalise on sectoral rebounds without the volatility often associated with smaller stocks.

Investor Takeaways and Outlook
For investors and traders, the surge in open interest combined with strong price action and volume signals a favourable risk-reward scenario. The technical setup, supported by the stock trading above all major moving averages, suggests that SAIL could continue its upward trajectory in the near term.
However, market participants should remain vigilant to sector-specific risks such as raw material price volatility and regulatory changes that could impact steel production and profitability. Monitoring open interest trends alongside price and volume will be crucial to gauge the sustainability of the current rally.
Given the mid-cap classification and liquidity profile, SAIL remains an attractive candidate for portfolio inclusion, especially for investors seeking exposure to India’s industrial growth story through the ferrous metals sector.
Conclusion
Steel Authority Of India Ltd.’s recent open interest surge in derivatives, coupled with strong price gains and rising volumes, reflects a robust bullish sentiment among market participants. The upgrade to a Buy rating by MarketsMOJO and the stock’s outperformance relative to sector and benchmark indices further bolster its investment appeal. While risks remain, the current market positioning suggests that SAIL is well placed to benefit from a potential sectoral recovery and sustained investor interest.
