Currently, I have about $3200 in my Roth IRA from my 2014 contribution of $3000. By the end of 2015, I'm hoping to contribute the yearly max of $5500.
My current assets are invested in Vanguard's VTSMX which is a 100% domestic stock index fund. I'm assuming that I should now diversify my portfolio with some international stocks and some bonds. Where should I put the $5500? I'm open to all suggestions.
Background info that is probably pertinent: I'm currently a 19 year old college sophomore so I won't be retiring for a long time. I'm making about $10k a year and have college fully covered by scholarships. So that's why I'm able to invest a good amount for my age.
