Could be the same one, maybe a new one.
Yesterday the U was serious, usually they pull out when they seem in danger of getting hit.
So now we believe the U's are genuine? I personally would like him/her to move up a couple points.
Then again the U was sitting at 190 yesterday whille the sp was at 192- 193
As I said a few weeks back, I think we will see a change of interest notice soon
cheers
