I am an old $AMBS investor, since 2012. He did many mistakes on the financial side (toxic debts) and communication side. He pumped a lot the AMBS pipeline, very unusual behavior for a CEO. Even worst, no updates since too much time. For sure he didn't have the correct experience at that time.
That being said, I continued to follow him and I jumped in Todos as well. I agree with you. Your summary of the opportunities is right. I expect to see better moves in the future. It is also a matter of visibility, OTC doesn't help.
I know perfectly the risk we are running.
