What led to the Sensex losing nearly 850 points from the peak on Tuesday 09 June?

The Nifty and Sensex corrected sharply in the second half due to losses in banking shares even as Reliance Industries weakened ahead of rights listing. Most of the heavyweights like RIL, ICICI Bank, HDFC Bank and Bharti gave up 2-3%. One reason for the sharp fall was the weakness in the European markets, which rubbed off on India too. Healthcare was the only sector to perform relatively well on Tuesday.
