India's BSE Sensex managed to close about 0.2% up at 83,432.9 on Friday, halting a two-day losing streak, in a choppy session that reflected cautious optimism amid ongoing global and domestic uncertainties. Market sentiment remained fragile ahead of the July 9 US tariff deadline and a possible US-India trade deal, while regulatory actions by Sebi - including an interim ban on US quant firm Jane Street for alleged market manipulation - added to the cautious mood. Banking stocks and techs led sectorial gains. The top gainer on the Sensex was Bajaj Finance, up 1.7%, after it reported a 25% rise in assets under management in a pre-quarterly update. Infosys, Hindustan Unilever, ICICI Bank, Bajaj Finserv, HCL, Ultratech Cement, Eternal and TCS also were among the top performers. The laggards were Trent, Tata Steel, M&M, Maruti and Tech Mahindra. For the week, the Sensex notched a 0.7% loss, its first weekly decline in three weeks.
