The problem with PG is that he gives people the impression that he knows more than he does. As a stock promoter, he only knows what management is willing to tell him - basically what they want him to tell potential investors. But he presents details including maps of geological formations, along with large amounts of speculation on anything that may have some impact on the stock in question.
This leads some investors into believing that PG is a geologist, or an economist or even a god, when in fact he is an intelligent high school dropout who started a business promoting stocks. Nothing wrong with that, people just have to be aware of it.
Of course, now he's trying to reinvent himself as a money manager. I suspect that won't end well for investors either.
