Sensex falls 418 points, Nifty down 187 on weak Q3 earnings

Indian stock markets opened on a weak note on Monday, extending their losses amid lacklustre Q3 earnings and global uncertainties. Both benchmark indices declined, with Nifty 50 falling 186.55 points and Sensex shedding 417.61 points. Analysts attribute the downturn to weak corporate performance and concerns over market valuations.
