Personally, I don't think it's actually possible to read too much into company directors putting their own cash into something they supposedly believe in, with some of them working for RAC for a number of years.
My point is still valid regarding even a billionaire would throw $100k into an investment he believes in, to receive that kind of 'outsized returns for shareholders' (as the saying goes....).

JC sold $750k worth (if my memory is still functional). If this was ACTUALLY used to pay the tax man, then I'd say he's doing better than average. So would a $100k purchase to gain ~50x that amount in a drug you're promoting be considered as a good investment?
