Good point. It does get these sharp upward spikes (i.e. Friday AM it got as high as $13.40) and then late Monday through early Tuesday morning - even in the midst of an overall downward move. It even gets these on a daily basis usually in the first half hour of trading, but they quickly disappear. Maybe Hedge can provide an explanation of what may be happening.
Run a P&F chart. Going through $14 was an important event, since it put in a higher high and reinforced its position above the bearish resistance line. Since the $14 level, we've had another annoying pullback. I guess annoying if your long and a good thing if you're short. It's basically done a 50% retracement in its column of Xs. It's just typical JDSU behavior since mid 2011. It's tough to be long and equally as tough to be short.
