<prompt> Human: Background: My lil sister is a waitress who just graduated college. She makes college-level money. I want her to get introduced to retirement investing pretty early, so I thought this would be a good idea. However, with such a small amount, what funds do you think would be suited for it?P.S. I know she can only invest money that she earned, but I guess to get around this technicality she can invest 1K from her own wages and just put my gift to her savings account.Assistant: Vanguard target date funds have a 1k minimum.Human: Is a 3-fund portfolio for 1K not worth it?Assistant: Worth is subjective. I think its worth it.Human: Ok. If she does the 3-fund portfolio, what funds do you recommend for 1k?  <response>: The Vanguard target date funds.
