RE:TA - buy in now...NU has been beaten down since January 8th. The chart is weak, and it's true that this could be the point at which there is a trend reversal. These past two green days show that buyers are starting to show up, but it's still tentative. More buyers have to jump in now. A good sign would be a close at .20 or above. Any close over .27 signals a solid trend reversal.
Good Luck
