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 ?

Short selling is something different, going short is predicting a drop in price, this is more equivalent to day trading, the stock has reached a good price so you sell the position while it's high to take a profit before any correction or drop happens.
