Okay my mistake if that is not what you were implying. I've seen a few other people making that correlation in the past on here.

I'm no expert but I would assume it's common sense that if you are adding stock to your portfolio that just ran up from $150 to $232 a share in 2 months (like ALGT did last year) you are probably over paying. I could name hundreds of stocks that ran up 50% and dropped 50% shortly there after, ALGT is nothing unusual for 2015.
