How Did the Stock Market Perform Today?

Despite some volatility during the day, India's benchmark indices finished the session with strong gains. Here is a snapshot of the market's performance on September 3, 2025:

• S&P BSE Sensex: Closed at 80,568, up by 410 points (0.51%).

• NSE Nifty 50: Closed at 24,715, a gain of 135 points (0.55%).

The market demonstrated resilience, with a broad-based rally ensuring a positive close near the key psychological level of 24,700 for the Nifty 50.

What Were the Main Reasons for the Market Rally?

Two primary factors were responsible for lifting investor sentiment today:

1. Optimism Around the GST Council Meeting: Investors are hopeful about the outcomes of the two-day GST Council meeting. Discussions are expected to focus on the rationalisation of the GST structure, which could simplify the tax regime and provide a boost to several industries.

2. Strong Services Sector Data: The release of strong macroeconomic data provided a significant tailwind. The HSBC India Services Purchasing Managers' Index (PMI) surged to 62.9 in August, a 15-year high. This figure indicates robust expansion in the services sector, fuelled by strong international demand and a high influx of new orders.

Which Stocks and Sectors Were the Top Performers?

The rally was led by a powerful performance in the metal sector, which emerged as the day's clear winner.

Sectoral Performance Highlights:

• Nifty Metal: Surged by 3.11%, making it the top-gaining sector.

• Nifty Pharma: Gained a healthy 1.10%.

• Nifty PSU Bank: Rose by 1.03%.

• Nifty IT: Was the primary laggard, dropping by 0.74%.

How Did the Broader Market and Institutional Investors Fare?

The positive sentiment was not limited to large-cap stocks. The broader market also participated in the rally, signalling widespread investor confidence.

• Nifty Midcap 100: Closed 0.69% higher.

• Nifty SmallCap 100: Ended the day with a gain of 0.89%.

Regarding institutional activity, while specific flow data for September 3rd is awaited, investors continue to track the movements of Foreign Institutional Investors (FIIs) and Domestic Institutional Investors (DIIs). Their activity in stocks like HDFC Bank, ICICI Bank, and ITC is closely watched on platforms like Finology Ticker to gauge institutional conviction.

What Was the Influence from Global Markets?

Global market sentiment was cautiously optimistic. US stock futures saw a slight uptick after a federal court ruling in an antitrust case involving Alphabet was perceived as less severe than feared, offering some relief to the tech sector. This followed a session where major US indices had closed lower as investors booked profits after a recent rally.
