It's always good (for all of us) to have a sense of where resistance and supports are. If we're going to maintain a nice move up, chasing done at the open tends to erode bid-support and leaves the stock that much more volatile. If traders who got in yesterday much higher wants to grant those on the sidelines with some cheapies...let them fill you at 28. Not saying it can't go lower, only that 28 provides a good risk-reward ratio...particularly if the lots are sizable there.
