I don’t know the specific firm, but have worked in investment research and adjacent fields, including investment marketing; I would be extremely wary. Okay, I just clicked through on one of their “premium services”- it was slick, looked shady- there are no overt disclosures but that stuff can be hidden with unrelated parties- IDK it looks identical to paid investor relations marketing campaigns to me. I would stay away, even on their free recommendations.
The ad for the service was on Breitbart. Arrgh.
