I’m 35 years old and was curious if I’m headed in the right direction or not. I have a Roth IRA with about 5 shares in VXUS and 2 shares in VTI totaling only about $1,100. I’m investing about $100-$200 monthly into these Roth stocks. Should I add any other stocks or ETF’s to this combo? Or should I just let it grow and build over time? Thanks.
