If you trade at all on the big boards you know exactly why. Visa had a RECORD quarter and dropped $4, Mastercard same...it happens all the time. Investors secure their profits before earnings. They will come back up because of their potential and the earnings strengthen the support.
CVS today had great earnings and went up, thankfully my Calls are coming in nicely.
CVSI will do whatever it does, but it will be fine.
