For the full year, we have seen 2 estimates moving down in the past 60 days, compared with no upward revision. This trend has caused the loss estimate to widen, going from a loss of 20 cents a share a month ago to its current level of loss of 38 cents. Also, for the current quarter, Opko Health has seen 1 downward estimate revision versus no revision in the opposite direction, dragging the loss estimate down to loss of 11 cents a share from loss of 5 cents over the past 60 days. The stock also has seen some pretty dismal trading lately, as the share price has dropped 15.82% in the past month. So it may not be a good decision to keep this stock in your portfolio anymore, at least if you don't have a long time horizon to wait.
