If you can only invest in 1 company and must hold it for 5 years, which would you choose to max your return?

I'm not saying I have a friend going to jail for five years, but let's pretend I did. And this friend only wants to invest his money in 1 company. AFter he gets out he will need the max gains to start his pretend life again.

What company would you invets all your money in for 5 years to do this?

Now I could go on and on just to make sure this post isn't automatically rejected for not having a body with enough text, but I know Reddit and that's not required. But let's also say that I know Reddit and that is required. Know what I'm saying?
