The domestic equity indices extended their losing streak for the third consecutive session on Thursday, with major indices closing significantly lower despite a promising start to trading. The Nifty50 index, which opened strong above the 25,000 mark, quickly reversed course in early trading hours. The benchmark eventually closed below 24,750 points. Sector-wise, realty, automobile, and consumer durables stocks led the downward trend. However, IT and public sector bank shares showed resilience, emerging as outliers in an otherwise bearish market. Market volatility was particularly pronounced due to the scheduled expiry of weekly index options.
