Blue Star Ltd. Sees Significant Open Interest Surge Amid Strong Market Momentum

Open Interest and Volume Dynamics

On 10 Feb 2026, Blue Star’s open interest in futures and options contracts rose sharply to 17,246 from the previous 15,164, marking a 13.73% increase. This 2,082-contract jump in OI is significant, indicating fresh positions being established rather than existing ones being squared off. The accompanying volume of 28,430 contracts further underscores heightened trading activity, reflecting growing investor interest in the stock’s near-term prospects.

The futures segment alone accounted for a value of approximately ₹20,211.92 lakhs, while the options segment’s notional value was substantially higher at ₹16,449.99 crores. The combined derivatives turnover stood at ₹22,686.74 lakhs, highlighting the stock’s liquidity and attractiveness among derivatives traders.

Price Performance and Technical Positioning

Blue Star’s underlying equity price closed at ₹1,969, having touched an intraday high of ₹1,995.5, a 3.02% rise on the day. The stock has outperformed its sector by 1.51% and the broader Sensex by 1.15% on the same day, reflecting robust buying interest. Notably, Blue Star has recorded gains for three consecutive sessions, delivering a cumulative return of 5.66% during this period.

Technically, the stock is trading above all major moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — signalling a strong uptrend. This technical strength is corroborated by a surge in delivery volumes, which on 9 Feb reached 8.9 lakh shares, a remarkable 188.21% increase over the five-day average delivery volume. Such rising investor participation in the cash segment often precedes sustained price moves.

Market Positioning and Potential Directional Bets

The sharp increase in open interest alongside rising volumes suggests that market participants are positioning for further upside in Blue Star’s shares. The build-up in long futures and call option contracts points to bullish sentiment, with traders anticipating continued momentum in the near term. This is consistent with the stock’s recent upgrade in mojo grade from Sell to Hold on 30 Jan 2026, reflecting improved fundamentals and technical outlook.

However, the mojo score of 55.0 and a market cap grade of 2 indicate that while the stock shows promise, it remains a mid-cap with moderate risk factors. Investors should weigh these aspects carefully, especially given the sector’s cyclical nature and potential macroeconomic headwinds.

Liquidity and Trading Viability

Blue Star’s liquidity profile remains robust, with the stock’s traded value comfortably supporting trade sizes up to ₹3.19 crores based on 2% of the five-day average traded value. This ensures that institutional and retail investors alike can execute sizeable trades without significant market impact, an important consideration for derivatives traders looking to establish or unwind positions efficiently.

The stock’s mid-cap market capitalisation of ₹40,413 crores places it in a segment that often offers attractive growth potential balanced with manageable volatility, making it a preferred choice for investors seeking exposure to the Electronics & Appliances sector.

Sector and Benchmark Comparison

In comparison to its sector peers, Blue Star has outpaced the Electronics & Appliances sector’s one-day return of 0.09% and the Sensex’s 0.33% gain, reinforcing its relative strength. This outperformance, coupled with the derivatives market’s increased positioning, suggests that investors are favouring Blue Star amid broader sectoral consolidation.

Such relative strength often attracts momentum traders and institutional investors, which can further amplify price moves and open interest growth in the near term.

Outlook and Investor Considerations

While the surge in open interest and volume signals bullish positioning, investors should remain cautious of potential volatility given the stock’s mid-cap status and sector cyclicality. The recent mojo grade upgrade to Hold from Sell reflects a cautious optimism, suggesting that while fundamentals and technicals have improved, the stock is not yet a definitive buy.

Investors are advised to monitor key support levels around the 5-day and 20-day moving averages, as well as open interest trends in the coming sessions to gauge the sustainability of the current momentum. Additionally, tracking delivery volumes and sectoral developments will provide further clarity on the stock’s directional bias.

In summary, Blue Star Ltd. is currently attracting increased derivatives market interest, underpinned by strong price action and rising investor participation. This combination points to a positive near-term outlook, albeit with measured risk considerations.
