Just FYI I bought SVA on the chart alone. I know it's a biotech but that's IT. What I do know is the chart was a beaut, it was what I call 9 1/2 months pregnant. This stock hit the same resistance level 5 times. You don't see that too often. I'm not saying that there is no unknown fundamental reason like those mentioned in this thread. Of course it could be that. But it also may have just popped due to technical buyers like myself. I bought more here today this a.m. The chart is so strong base-wise that I feel pretty good holding this for awhile. $5.50 to $6.35 has been EXHAUSTED. And with the volume it's hard to make an argument for further trade down there minus news that would dictate it. So I'm a TA trader whose now holding with you longs. Good luck my friends.
