When does CEG after-hours trading start and end?
After-hours trading in CEG on the NASDAQ runs from 4:00 PM to 8:00 PM ET on trading days, immediately after the regular session closes. Not every broker offers the full window, and liquidity thins sharply after about 6:30 PM ET.
Will CEG's after-hours move hold at the open?

Fill rates this high mean a large after-hours move is more often faded than extended.
When does CEG report earnings?
