BSE and NSE will conduct special one-hour Diwali 'Muhurat Trading' sessions on Diwali on November 1, marking the start of Hindu calendar's Samvat 2081. The session will be held from 6:00pm-7:00 pm while pre-opening session will take place from 5:45pm-6:00pm. Investors may focus less on profits and more on the gesture as markets may be volatile in the session.
