This is just a global sell off and all institutions and investors are selling like there is no tomorrow. This is classic case of panic selling. The US markets fell by 1800 points on Wednesday and all global markets have taken a cue from them. The number of Coronavirus casualties are increasing outside China and now a total of 122 nations are affected. With most countries putting travel and trade advisories, the global economic activity virtually comes to a standstill. In India, there is just an absolute sell-off in equities and even traders who have profitable positions are selling to make up for losses in other positions. That is what is triggering this vertical crash.
