Why does India's stock market open on Diwali?

India's stock market opens for a Muhurat trading session on Diwali. The tradition began at Bombay Stock Exchange in 1957. It has its roots in the business customs of communities such as Gujarati and Marwari traders, who traditionally began their financial year on Diwali by worshipping Goddess Lakshmi. Brokerage offices around Mumbai later adopted these rituals, considering the session auspicious.
