The best friend any investor has is time. The longer the time horizon, the more time you have to make your money and the markets work for you. Just look at the performance of the S&P 500. Between Dec. 1, 2010, and Dec. 1, 2020, the S&P 500 has increased about 200%, or roughly 11.6% on an annualized basis.
So if you had invested, say, $10,000 in an S&P 500 exchange-traded fund, or ETF, 10 years ago this month, you’d have about $50,000 right now, with $100 contributions each month.
