$0.4 is the first stop. I bet that so far Guo spent less than 0.5 millions. From $0.4 to $0.75, he needs to spend probably 2 millions. It will be much easier from $0.75 to $1. If he can reach $1 with 3 millions, he has 2 millions left for keeping the share price over $1. Then he achieves his goal to satisfy Nasdaq's requirement. Unless there is short covering, do not expect the share price over $1 too much
