That makes perfectly sense to me! They are in this because they can earn money on the deal in the long run.
So they don't just do it because they think Mr. Da Silva is a heck of a guy, but because they hope to make money in the long run (like everyone else including myself). So nothing wrong with that at all, but it just means that one may need to be a bit more sceptical when reading Eric David's recommendations.
I believe they are right regarding this stock, but I have my doubts regarding some of the other stocks he recommends.
