<prompt> Human: I had a 401K from a company I worked with about 5 years ago when I was 25. I contributed for about two years, changes jobbed, and I guess I forgot about it.What does one do with an old 401K? I have a new 401K with my current employer, and a Roth IRA through fidelity.edit: Thank you for the suggestions, really appreciate it.  <response>: Roll over 401k to Fidelity and open a traditional IRA. Is May offset some expenses or charges that Fidelity might have with larger balances.
