Such is life in the stock world. This is still a very good company, well managed, I would have patience. This stock does move around pretty well and don't see a problem with Expedia's business.
What you should do that is more important than your 5 grand, is enjoy the weather and don't worry.
By the way, how much money did you lose (You don't lose anything until you sell) - it doesn't seem that much if you bought 5k? I say you are down about $500, which I do not think will break the bank.
"Investing" is the keyword. When you invest you lose and gain money, depending on what is going on. The hope is that you gain more than you lose or why invest in the first place? How much gain will make it worth your time and energy? That's up to you.
Get out or get long. It's not rebounding today buddy. If you're like me and the other AH chumps, which it seems you are, you took a 14% hit. (Down from $67-69). Per my math 14% x $5000 = 700. That's nothing to sneeze at but hardly a hard loss for any retail investor.
Accept you got burned. You're not alone. Live to play another day chief.
