ARM has a much wider base of serious fund investors behind it, which our data treats as a stronger signal of confidence — HOOD has far fewer, so it's a much smaller footprint in the professional investing world right now.

But watch out
Smart-money signals lag the market (13F filings ~45 days) and never guarantee direction — always check the latest price and news yourself.
