What a day today (Fri 13th Mar 2020) turned out to be in the markets! A 10% fall shortly after opening triggered the lower circuit, led to a halt in trading in the NSE and there was a recovery! Sensex recovered 4% intraday! Nifty 3.81%. Here is why we witnessed something special today.
Earlier today we found that we are in the middle of the biggest Sensex Crash but it could be a healthy one for market homogenisation. This is the intraday Sensex movement from 11 to 13th Mar 2020. The opening, closing, highest and lowest prices are shown.

The reason for such a large variation is said to be short covering. This is when trader short a stock -borrow shares and sell it immediately in the hope they can re-buy at a lower price. This could drive down the market if prevalent. When (if) the price falls lower, they would re-purchase at a lower price for profit. This would drip up the price and is possibly why the market bounced back after trading was halted.
