>>95642064Too many people bought in anticipation of earnings. After earnings as always some people want to take profits.
Because too many people bought before earnings, there were less people buying than selling after earnings. (also because institutions know this, they start shorting the stock).
As it dives further, people panic sell or sell to stop their losses (hoping to buy back at a lower price and avoid most of the drop).
This furthur pressures the price lower.
