Monday, 23 February 2026: Modest Decline Amid Sensex Gains

Blue Star Ltd began the week at Rs.1,962.25, registering a decline of 0.30% despite the Sensex rising 0.39% to close at 36,817.86. The stock’s modest fall contrasted with broader market optimism, signalling early caution among investors. Trading volume was moderate at 8,308 shares, reflecting subdued participation as the stock navigated mixed market signals.

Tuesday, 24 February 2026: Technical Momentum Shifts Amid Mixed Signals

The stock edged down further by 0.14% to Rs.1,959.50 on 24 February, while the Sensex declined 0.78%. This day was notable for a nuanced shift in Blue Star’s technical momentum. Analysis revealed a transition from a clear bullish stance to a mildly bullish one, with daily moving averages remaining positive but weekly and monthly indicators presenting mixed signals.

Specifically, the weekly MACD stayed bullish, supporting short-term momentum, but the monthly MACD turned mildly bearish, suggesting longer-term caution. The weekly RSI shifted bearish, indicating short-term selling pressure, while Bollinger Bands and moving averages showed mild optimism. Volume-based indicators like On-Balance Volume were neutral to mildly bullish on longer timeframes, reflecting a complex technical landscape.

Wednesday, 25 February 2026: Continued Weakness Amid Market Recovery

On 25 February, Blue Star’s price declined 1.00% to Rs.1,940.00, despite the Sensex rebounding 0.41%. The stock’s underperformance amid a recovering market suggested persistent investor caution. Volume remained steady at 8,986 shares, with delivery volumes declining, indicating limited long-term investor participation. This day set the stage for a technical and sentiment shift that would emerge the following day.

Thursday, 26 February 2026: Open Interest Surge and Mojo Upgrade Signal Renewed Optimism

Thursday marked a pivotal day for Blue Star Ltd. The stock rebounded 1.32% to Rs.1,965.70 on robust volume of 157,177 shares, significantly higher than previous days. This price recovery followed five consecutive sessions of decline and coincided with a 13.24% surge in open interest in the derivatives segment, rising from 9,803 to 11,101 contracts. Futures volume was strong at 5,792 contracts, with combined futures and options notional value exceeding ₹7,576 crores.

This surge in open interest alongside price gains suggested fresh long positions and renewed market interest. The stock traded above key moving averages (20-day, 50-day, 100-day, 200-day), although it remained below the 5-day average, indicating short-term consolidation amid strengthening momentum.

Additionally, MarketsMOJO upgraded Blue Star’s mojo grade from Hold to Buy on 25 February, reflecting improved fundamentals, valuation, financial trends, and technical indicators. The upgrade was supported by strong long-term operating profit growth (CAGR 53.50%), solid profitability ratios (ROE 17.93%, ROCE 19.4%), and a conservative debt profile (Debt/EBITDA 0.40). Institutional ownership stood at 41.41%, signalling confidence from sophisticated investors.

Despite flat quarterly earnings and a premium valuation (EV/Capital Employed multiple of 11), the upgrade highlighted a balanced optimism supported by a shift to bullish technical momentum. Weekly MACD and KST indicators were bullish, daily moving averages turned decisively positive, and Bollinger Bands suggested an upward price channel. However, monthly momentum indicators remained mildly bearish, advising caution for longer-term investors.

Friday, 27 February 2026: Week Ends on a Weak Note Amid Market Sell-Off

Blue Star closed the week at Rs.1,940.80, down 1.27% on 27 February, with volume of 20,068 shares. The Sensex fell 1.16% to 36,322.56, reflecting broad market weakness. The stock’s decline on the final trading day erased some of the prior day’s gains, underscoring short-term volatility and profit-taking. Despite this, the technical upgrade and open interest surge earlier in the week provide a foundation for cautious optimism.

Key Takeaways

Positive Signals: The mojo grade upgrade to Buy and a mojo score of 72.0 reflect improved fundamentals and technical momentum. The significant open interest surge on 26 February indicates renewed market interest and potential for price appreciation. Long-term fundamentals remain robust with strong operating profit growth, solid profitability ratios, and low leverage. Technical indicators on weekly and daily timeframes show bullish momentum supported by moving averages and volume trends.

Cautionary Notes: The stock declined 1.39% over the week, underperforming the Sensex’s 0.96% fall, with short-term volatility evident. Monthly momentum indicators remain mildly bearish, suggesting longer-term consolidation or resistance. Delivery volumes have decreased, implying limited conviction from long-term investors. Valuation remains premium, and recent quarterly earnings were flat, which may temper near-term upside.

Conclusion

Blue Star Ltd’s week was characterised by a complex interplay of technical upgrades, increased derivatives activity, and price volatility. Despite a weekly decline of 1.39%, the stock’s mojo grade upgrade to Buy and a 13.24% open interest surge signal renewed optimism among traders and analysts. The technical momentum shift to bullish on shorter timeframes, combined with strong long-term fundamentals, provides a cautiously positive outlook.

Investors should weigh the mixed monthly momentum signals and recent earnings softness against the improved technical backdrop and institutional confidence. The stock’s underperformance relative to the Sensex this week may offer selective entry opportunities, but vigilance is warranted given the premium valuation and short-term volatility. Overall, Blue Star Ltd remains a stock to watch closely as it navigates this transitional phase within the electronics and appliances sector.
