If you invested $100 in AMD stock (AMD) at the beginning of December 1984, you would have about $2,696.48 by March 2026. This is a return on investment of 2,596.48%, or 8.31% per year.
This investment beats inflation during this period for an inflation-adjusted return of about 759.87% cumulatively, or 5.35% per year.
If you used dollar-cost averaging (monthly) instead of a lump-sum investment, you'd have $6,901.38.
The nominal return on investment of $100 is $2,596.48, or 2,596.48%. This means by March 2026 you would have $2,696.48.
However, it is important to take inflation into account when evaluating a long-term investment. You can convert these returns to their real value using an inflation calculation based on the U.S. Bureau of Labor Statistics Consumer Price Index (CPI).
In this case, the CPI in December 1984 was 105.300 and the CPI in March 2026 was 330.213.
Adjusted for inflation, the $2,696.48 nominal end value would have a real return of roughly $759.87 in 1984 dollars. This means the inflation-adjusted return is 759.87% as opposed to the original 2,596.48%.
The table below shows the full dataset pertaining to a $100 investment over the 166-month period between 1984 and 2026.

AMD dollar-cost averaging
Dollar-cost averaging is an alternative to investing the full lump-sum of $100 up front. Instead, the capital is invested over a period of time.
Consider a strategy in which $100 was invested in AMD stock (AMD) over a period of no more than 24 months beginning in 1984. This would result in a final amount of $6,901.38. In this particular case, dollar-cost average returns are greater than the returns of a lump-sum investment (which ends with $2,696.48).
