I'm a 20 year old college student, I have about 1.2k in VOO, I'm looking to invest about 23k over the next couple of months. I have set up a 70/30 split (US/International), would you guys recommend only buying VOO for US etfs, or should I look into some other options as well? For international etfs im looking at VXUS. I don't plan on living off of stocks only, I'm hoping to make them act as one of my passive income source as I age(hopefully)
