Nifty slipped below 24,900 Friday, ending a four-day winning streak as traders brace for US tariffs midweek. SEBI RAs flagged 24,800 as the key level- a break could extend the fall toward 24,560, while reclaiming 25,000 may revive momentum. Powell's dovish tone supports risk assets, but tariff headwinds keep traders cautious on equities and the rupee.
