Sensex falls over 800 points from day's high, Nifty slips below 23,000

BSE Sensex has fallen over 834 points intraday from its day's high of 74,849.75, while Nifty 50 fell nearly 236 points to go below the 23,000 mark. This is primarily due to a fall in private banks' shares following Q2 results and surging crude oil prices amid geopolitical tensions. Weak global cues, a tech sell-off and FII outflows added pressure.
