Should I invest in sports/entertainment Stocks?

I don't invest in stocks that often, but from time to time I like to update my portfolio. I've been reading about the merge between UFC and WWE, and I've seen how WWE stocks have increased in value. I think it's too late to buy them, or at least I think they're already too expensive. The stocks I own are mostly energy and technology stocks, but I think I should get into entertainment/sports. What stocks do you find interesting and why?
