Trying to time a run up on expected news, and maybe get in before NEPH runs away if FDA clearances come in next week. Expect a slow but steady rise over next week, with a fast dip if no announcement by Friday. If clearances come it by Friday or Monday, expect a fast run.
Regardless of the rise, for the next several days it will be riskier to sell (even at a profit) than it will be to hold. JMHO
