BIIB has not recovered since Droptober, and it's since been hovering between its 50, 100, and 200 dma.
Round top, multi H & S, what have you.
But it all depends on the overall market. We can get another post puberty growth spur and BIIB can finally break above its 50 and 100 dma.
But, the market is at its all time high, and we can all admit that QQQ has been the weak link last week. A pull back would send it back to 290-300 area, and then 270-280.
