If you had invested $100K in the IVV S&P 500 ETF over the last 10 years and did nothing you would have turned your money into $400k plus dividends along the way. Thats a 15% compound return, very few fund managers and individual investors have been able to do this.
This is the advice Warren Buffet has been giving for a long time. Maybe worth having a part of balanced strategy, see chart below.
