Because people sell off shares to take profit after such a massive increase? Par for the course for any stock where a similar thing happens.

So they were short selling ?

No, You have profit takers. basically a combination of day traders that buy in on the rise and sell end of day and others that simply decide to cash in on such a large surge by selling out (some with the intention of rebuying on the next trading day post the usual drop after such a surge).
