Topic: My recommendation, not that you asked for one

If you like to invest with low costs (which makes sense) in passive investment funds but with a bit of a twist that allows outperformance in comparison with bland index funds, you might want to do some research into Dimensional Fund Advisors. Another US company, I think by now third biggest after Vanguard and Pioneer. They offer ONLY passive investment cours ripple funds with an evidence based underlying strategy.
