The BSE has experienced a significant decline in market capitalisation, with a total loss of nearly Rs 50 lakh crore since its peak on September 27.

The current market capitalisation stands at Rs 429.33 lakh crore, down from the record high of Rs 477.93 lakh crore.

Public Sector Undertakings (PSUs) have been hit the hardest, losing over Rs 15 lakh crore, which accounts for 31 percent of the total market erosion.

BSE Sensex constituent firms have seen a decline of Rs 13.28 lakh crore, representing a 27.3 percent drop, while BSE MidCap companies lost Rs 8.36 lakh crore, or 17.2 percent.

BSE SmallCap firms experienced a market capitalisation erosion of Rs 6.87 lakh crore, a decline of 14.1 percent, with other firms collectively losing over Rs 5 lakh crore, marking a 10.5 percent decrease.

The market downturn is attributed to persistent selling by foreign investors, disappointing September quarter earnings amid high domestic valuations, and expectations of the Reserve Bank of India maintaining interest rates due to ongoing inflation concerns.

Additionally, global geopolitical tensions and the potential return of Donald Trump to power in the U.S. are raising fears of renewed trade wars, further dampening market sentiment.
