The result
Over 6 years the money doubled about 1.1 times. Without reinvesting dividends it would be $20,216: dividends account for 7% of the final value.
Inflation matters over this long. $10,000 in 2021 had the buying power of about $12,806 today, so the real gain is $21,793 against $12,806: still 1.7× the buying power, or 9.8% a year above inflation.
It was not a smooth ride. The value fell 19% from a high around Oct 2022, during the 2022 inflation sell-off. Holding through it was the price of the final number.
