<prompt> Human: My current companys 401k, plus a rollover IRA I have from a from a previous job, are all with the same brokerage company. I wonder if, like with bank accounts and max. FDIC coverage, I should have my retirement accounts split between different firms, like Fidelity and Vanguard, for example. What is the realistic risk of having all of my retirement accounts in one place, especially if its with a big firm, like Fidelity or Vanguard? Is there some risk of my losing all of my money if the company goes under?  <response>: Brokerage accounts are protected by SPIC up to 500K. It would be unlikely that one of the large firms goes under and it would be even more unlikely that it affects customer accounts. If you start getting to the 500K amount then think about opening or moving one account.
