One of my main questions and a question always ask

One of my main questions and a question always asked me by my friends when I tell them about Cytodyn is: if Cytodyn is such an amazing investment and the sciences is so spectacular why are investors like us even getting a chance at this investment, why are the venture capitalists and sophisticated investors not snapping up every share and driving the price up why is no big investment bank or investor come in and take a large position?

I don’t have a good answer for them. I don’t even understand myself? It seems to be beyond what I can comprehend!
