The market opened on a strong note, with Sensex crossing 82,200 in early trade before moderating due to profit booking in certain sectors.
Traders attribute this resilience to positive domestic cues, including a parliamentary panel’s GST recommendations and optimism around India’s capital market reaching a $5 trillion valuation.
With over 200 million demat accounts now active, retail participation continues to fuel growth, though regulators eye measures to curb speculative trading.

Market Overview
Benchmark indices maintained their upward trajectory today, defying mixed global signals. The Sensex gained 142.97 points, or 0.17%, marking its sixth straight win, while Nifty rose 69.90 points, or 0.28%. Broader markets
showed mixed performance: the Nifty Midcap 100 dipped slightly, but the Nifty Smallcap index held firm against slowdown pressures.
Trading volumes remained healthy, with advances outnumbering declines on the BSE. Investors focused on pharma and banking stocks, while auto and FMCG sectors faced headwinds from proposed tax changes.
The India VIX, a measure of market volatility, eased marginally, signaling reduced fear among participants. For real-time charts and data, refer to the NSE India official website.
This performance aligns with broader economic indicators. A recent SBI report projects India’s GDP growth at 7% for the first quarter of FY26, surpassing the RBI’s estimate.
Such forecasts bolster investor sentiment, especially as foreign institutional investors (FIIs) turned net buyers today, infusing fresh capital amid concerns over US tariffs and outflows.

Top Gainers and Losers
Several stocks stole the spotlight today with impressive gains and notable declines. IDBI Bank surged 8% following updates on its divestment process, where due diligence by qualified bidders nears completion, as stated by DIPAM Secretary.
This news propelled banking stocks higher, with ICICI Bank contributing significantly to Sensex’s rise.
Other top gainers included Godawari Power and Ispat, Amara Raja Energy & Mobility, and HDFC Life, recommended by analysts for their strong fundamentals.
Railtel and Clean Science also featured prominently in stocks to watch, driven by positive order wins and earnings outlooks.
On the flip side, auto giants like those in the luxury segment faced pressure from GST panel proposals to tax high-end cars at 40%.
FMCG stocks dipped amid broader tax slab revisions, with losers including select names from the sector. For a complete list of gainers and losers, check Moneycontrol’s dedicated page.
Ex-dividend stocks added intrigue today. Coal India, RVNL, HAL, Thomas Cook, and Honda India Power traded ex-dividend, attracting dividend hunters.
These moves underscore the importance of tracking corporate actions for portfolio strategies.

Sector Performance
Pharma emerged as the star performer, lifting indices with gains in key players. Analysts attribute this to export growth and favorable policy tailwinds.
Conversely, auto and FMCG sectors lagged, impacted by GST overhaul talks that propose scrapping 12% and 28% slabs.
The Group of Ministers (GoM) accepted the Centre’s proposal, potentially streamlining taxes but raising costs for certain goods.
Banking and financial services held steady, buoyed by IDBI’s rally and BharatPe’s executive appointments ahead of a potential IPO.
IT stocks like Infosys remained watchful amid global cues, while metals showed resilience on commodity price upticks.
The tobacco sector drew attention with India ranking as the world’s second-largest consumer, projecting a ₹6 lakh crore market by 2032. This highlights untapped opportunities but also health concerns. For sector-specific indices, visit BSE India’s sector page.
Key News and Developments
