APKT was up 6% during the day, only to tank over 10% after hours.
INFN, on the other hand, was up 5% during the day and popped another 10% after hours.
GMCR was flat during the day, and jumped 24% after hours.
How about SFLY? It rallied 6.5% during the day, only to dive 14% after hours, and finished the next session up 7.8% (that's over 25% move from the after hours low!!!) Who'd have thunk it?!
Earnings plays are casino plays however you slice it.
