Plenty of selling into the upper band (with previous healthy volume), today (and past two days) we have a low volume build up and breakout (today). Thinking this will fail (no volume associated with move up on shorter time frames), and then fall back to the lower support at the 9.00 level.
Good potential for an earnings surprise ($0.08 EPS), so with an estimate at $0.02 EPS, this could give you a good reason to power through the upper bound. (no sellers up their, just profit taking). Be ready just a couple of more days.
