While you are right that day traders have been and are very active in this stock, your other claims are wrong. It has not followed the pattern you claim, up at the open, down at the close, but has 90% of the time followed the major indexes, and is in fact part of one of the indexes (RUT 2000 IIRC), which is part of why it tracks the indexes 90% of the time. The other 10% has been news driven divergence.
Yes 40 cents has been major resistance, as it was once support, but this is a ully reporting, major market cap, real biotech, Nasdaq stock, not a pinky P&D stock, so your claim that "the company dumps new shares at the close" is absolutely false!
