Moody's Analytics on Friday cautioned that declining political stability and the need for consensus-building among the National Democratic Alliance (NDA) partners, who will form the new government at the Centre, could weaken investor confidence in the near term. The ratings agency noted a significant downturn in key stock indices, with the NIFTY 50 and the BSE Sensex falling more than __________ on the day the election results came out, representing the biggest one-day retreats in four years.
