Over 9 years the money doubled about 1.6 times. Without reinvesting dividends it would be $2,749: dividends account for 12% of the final value.

Inflation matters over this long. $1,000 in 2018 had the buying power of about $1,351 today, so the real gain is $3,135 against $1,351: still 2.3× the buying power, or 10.2% 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.
