When can we expect to see ARM Holdings in the Stocks ISA?
Not until they decide to go public and list their ordinary shares in a recognised exchange.
Technically ARM Holding is still a private company with no public share offerings. Their listing is on Nasdaq is an ADR. Basically its a “receipt” for a right to the value of “certain number of” stocks. You can google the difference between a stock and an ADR (or ADS in a similar manner)
you can buy it in invest, or sipp not in isa.
edit: I was wondering “this must have been asked before” and you asked the exact same thing few months back…
T212 SIPP is some way off… but I take your point… you are correct. Unless you have an account with Fidelity who for reasons only knows why don’t allow ARM in a SIPP ARM Holdings PLC ADR Company Profile | ARM | US0420682058 | Fidelity
