My read of the 3-yr. Chart (ameritrade)
dec. 2010= first shoulder
april 2011 head
sept. 2011 2nd. Shoulder
march 2012,a rally back to 2nd.shoulder level,followed by a crash below the neckline.
sept 2012 another rally to 40, which constitutes a second head in this 3-year pattern.
june 2013 another crash to match the 3-yr low.
not exactly an investment stock,but a great trading stock
