<prompt> Human: Im 26 and Opened up a Roth ira about week ago on Schwab and put the entire 5,500 into swyjx. I understand I need to diversify but does putting it all in a target fund solve the diversifying problem especially for a person who knows nothing about investing?  <response>: A target date fund will diversify for you. If you are new to investing just putting it all in a target date fund is fine.
