Stock Market Today – Key Drivers and Market Sentiment

The Stock market rally August 19 2025 was fuelled largely by optimism over the government’s proposed reforms in the Goods and Services Tax (GST) regime, expected to be rolled out by Diwali. Analysts said the recent upgrade of India’s credit rating, along with signs of easing global geopolitical risks, also helped lift investor sentiment. According to Vinod Nair, Head of Research at Geojit Investments, the market outlook has shifted from consolidation to a more constructive and growth-oriented stance in the near term.

Sector Performance and Top Movers

Among the Sensex constituents, Tata Motors was the top performer with a gain of 3.5%, followed by Adani Ports at 3.16% and Reliance Industries at 2.82%. Tech Mahindra, Kotak Mahindra Bank, Hindustan Unilever and Maruti Suzuki were also notable gainers. However, certain financial and utility stocks, including Bajaj Finserv, Power Grid Corporation, Mahindra & Mahindra and HCL Technologies, closed in the red due to profit-taking.
