Don't panic... last quarter it beat by 5 cents, but the stocks opened gap down over $6 the next day, and down as much as close to $7 before it reverse course... it had an intraday swing or spread of $7.11 that day... 9 trading days later, it finally closed above the pre-earning day close... and went to as high as $10 above that 3 weeks later... as I write this, AH has crawled back up to $64.50, so you are good so far, until they screw it up big in the conference call... hope not!
If you seriously bought 5000 shares, I hope you didn't use full margin. GMCR is a notoriously volatile stock on after earnings. Due to the weak Q1 guidance, this could easily drop 10-15% tomorrow. However, with the blow out earnings, stock repurchase, and dividend, this could open low and quickly rise just as easy. I won't even begin to predict which way it is headed.
