The E means they are deliquent on their filings (late) so they have a grace period (30 days usually). When the E was put on it went from .14 - .066 if i recall correctly, so expect a similar move to the upside if they file.
Normally when you get an E put on, you lose a lot of value, but once/if the E is taken off it will rocket right back up, normally even higher than before.
The reason for the move up last year was really just traders accumulating positions regarding all the rumors of the big run coming. You should do some DD to find out what is set to occur to have a better idea about a sell target.
