Screenulator detected topline resistance breakout for ATHN, among many other stocks. These days, there are so many top line breakouts, I see them as good opportunities for long and shorts. In short term, they are good for fading the gap, and in long term, there may be much more upside if the company has solid fundamentals. Some more recent candidates are: ATHN, GMCR, MDRX, PAGG, PT, GDW, PAR, RSCR, TLT See http://www.screenulator.com/cgi-bin/view_screen?id=8 for many more such picks daily. They are based on chart pattern and trend line analysis done by complex pattern recognition algorithm, all available for free! I have made many good trades based on this approach.
