Indian stock markets opened the week on a positive note, with the BSE Sensex climbing 296.94 points to 79,520.05 and the NSE Nifty rising 85.2 points to 24,089.95. However, both indices soon turned negative due to fresh foreign fund outflows and caution ahead of the upcoming earnings season. Key stocks in focus included Bajaj Finance, Titan, and Infosys, which saw gains, while Kotak Mahindra Bank and Tata Steel were among the laggards. In the broader market, Nifty IT led sectoral gains, rebounding after contributing to last week's market decline. The market's early gains were pared amid concerns over high valuations and a stronger US dollar.
