It sounds fairly straightforward. So to measure trustworthiness, I'm going to guess we're going to need a preview of some previous decision making with their clients' money. Admittedly, the stock market hasn't ever been something I explored. So I imagine knowing success of previous people they've worked with has some value.

He owned a large house for himself, and a lot of novelties from pop culture. SO this is unheard of for him . And while he's done much better with his pursuits here than he had been doing when he first arrived, it can always be better. ]
