Hows APT holders value the company?

I have been holding since the merger and offloaded more than 1/3 of them at $7. I have review the numbers and wondering where we are right now. should we value the company based on p/s? looked at the half yearly report we can see revenue up 700% to $50m, if we take full year number to $100m in revenue, p/s is more than 20x, which i would not say its cheap. But who knows? I have sold down A2M from $3, $7, $8 and every move of selling down prove me a stupid. any thoughts?
