You're an amateur. Yes, it does not mean much when price trends are flat.
BUT WHAT YOU FAIL TO SEE IS THAT ELAN IS ON A BREAK-OUT PATTERN AND GREEN FOR THE LAST FEW DAYS! There is a break-out alert in Wall St. on ELAN. So yes, pre-market and after-market buying has been rampant. And that is key.
Before you open your mouth. Know 'when' pre-market and after-market does not mean much. BUT DURING A BREAK-OUT PATTERN, it does mean something.
