Nick it could be for any number of reasons. I understand the banking sector in Greece has been down all week. I would guess there are people short selling this stock too. They want to drive it back to .25. It may be time to sell. I think ETE:GR is going to break below $2.00 and that's where I'm invested, ETE:GR. NBGIF is $2.43. I can't afford the losses anymore. I'll buy again if things look as if they are improving.
I was thinking, the people who bought National Bank of Greece before 2015 got hit with 2 reverse splits. They got totally wiped out. I can't lose everything here.
I'm going to head over to GLUU and park my money there for a while. I saw them back when they were at $3.00 a share but I went with NBGGY instead. Now they are $7.00 and change. Also maybe put some cash in APPS. I also spotted them at .50, now they are $1.32 Good luck to you. I'll keep this on the radar for when times are better in Greece.
