What's wrong with people!

I have the largest position on GME. I still believe in gaming sector, therefore, I still keep my position in GME. Today, they announced the result of holiday sales. All the numbers are up, they even raised guidance for Q4 result. However, the stock price plunge more than 5% despite of those positive numbers, I just don't get it sometimes. One Analyst said that "people sell on the news" no matter if it's a good news or bad news. The technical indicators also not looking so great for GME. Pretty soon, people will need to realize that GME is actually a great stock to buy especially after it replaces Dow Jones in S & P 500 index.
