IMO, exit strategies will vary by each situation. If someone offered me $2 a share today, I'd bankroll all of it believeing I could buy back in at some point (maybe at a higher rate) once more is known. However, if I KNEW DM had a settlement coming, I'd let it all ride.
Everyone should have an exit strategy -- Crammer's famous line:
Bulls make money, Bears make money, but greedy Pigs get slaughtered.
