The takeaway

⚪Neutral

ARM has a bit more institutional backing based on filing count, making it the more 'crowded by pros' pick, while OKLO offers a similar quality of backers but in a newer, less-proven space — it really comes down to whether you prefer established AI infrastructure or early-stage energy disruption.

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.
