I don't see any news event, but EnerNOC (ENOC) has already traded an entire day's worth of volume in the first 45 minutes, and is up 11%.  This has obviously taken it right back over the 50 day moving average.  Extremely frustrated on this one as it broke support last week, we cut back... and today it reverses massively.  This was our largest position at this time last week; now it's an afterthought..  Difficult to rebuy something up 11% ...

Long EnerNOC in fund; no personal position
