ARM

Key Takeaways

• Arm sells the instruction-set blueprint that nearly every smartphone chip is built on, a royalty model that produces a gross margin near 98% because the company collects a fee on silicon it does not manufacture. • The defining risk is the price: at roughly $439 the stock trades at a level no valuation method reaches, including the forward-growth methods, so the buyer is underwriting a data center expansion that is real but still small in the trailing numbers. • What to watch is data center roy

Institutional ownership

726 institutional managers reported holding ARM in 13F filings for the quarter ended 2026-03-31. Together they hold about 8% of the company; the top 10 hold 3%. 173 opened new positions that quarter. Held by Morgan Stanley, Invesco, FMR (Fidelity), among others. On the short side, 16.4M shares were sold short as of the 2026-06-15 count, about 2% of shares outstanding (1.3 days of typical volume to cover).
