What our data shows

Coinbase Global, Inc. Class A Common Stock logo COIN Coinbase Global, Inc. Class A Common Stock ⚪Neutral
Only 65 big professional investment funds have reported owning this stock, which is a much smaller show of hands compared to ARM, suggesting less widespread confidence from institutional investors.

The takeaway

⚪Neutral

ARM has a much bigger crowd of serious institutional investors backing it, which is a stronger signal of confidence from the smart money; COIN has far fewer of those big backers, so the conviction behind it looks thinner based on what we can see.

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.
