<prompt> Human: I was curious, is it possible to have both a Roth IRA and an index fund? If I contribute the max of 5,500 per year to my Roth IRA, is it then also possible to have an index fund and contribute?  <response>: An index fund is a type of investment. A Roth IRA is a type of account.Accounts are the things that have investments in them, so your question really makes no sense.To answer the question youre trying to ask: Yes. You can have both a Roth IRA and a regular usually called taxable account.
