<prompt> Human: Is it a good idea to have all my IRA, 401K, and brokerage accounts all under one financial institution e.g. Fidelity. It certainly would make maintaining them a lot easier. If the institution fails would I lose all my investments all at once?  <response>: You are insured up to 500k from broker failure via SIPC insurance with Fidelity. Or, you could move your accounts to Vanguard, which is basically never going to fail due to its structure. See Vanguard safetyI wouldnt think twice about keeping accounts with Fidelity though. Theyre fine.
