EMS made a big move on high volume due to a "review of strategic options", meaning it is looking to get acquired. Why it got so much interest today is beyond me, because, as far as I know, there are no takers. The price relative line speaks volumes about this stock. One oddity I saw here; with pivot points at 51.50 and about 55.50. that would put the next one around 59.50. That is almost exactly where it gapped up tt.
