TALLIVOIf You Invested in 1980
One of the best long runs available in the whole record. Worth seeing next to 2000 — two decades apart, opposite ends of the table.
$10,000 invested in January 1980 would be $485,000 today, in 2026 money — 48.50× the original, or 8.71% a year after inflation over 46.5 years. Along the way it fell 51.8% from its peak, bottoming in Mar 2009.
Dividends are reinvested and the figure is adjusted by CPI; before inflation the same run returned 12.19% a year. It excludes fees and taxes and covers US large-cap stocks only.
Where 1980 ranks
Of the 155 years someone could have started in this record, 1980 ranks 22nd on real annualised return. The median start year returned 7.19% a year; 1980 returned 8.71%, ahead by 1.52% a year.
A gap that small looks negligible and is not. Over the 47 years since, the difference between this year’s return and the median compounds into a materially different ending balance — which is the case for caring when you start, and also the case for not trying to time it.
The ride, not just the return
8.71% a year is the summary. The experience was a 51.8% fall that bottomed in Mar 2009, and then 4.2 years to climb back to the peak it had before. Anyone who sold at the bottom locked in the loss and never saw the number at the top of this page.
What you would have sat through
4 separate falls of more than 20% since 1980. Each one is a moment somebody sold.
| Peak | Bottom | Fall | Took to fall | Back to peak |
|---|---|---|---|---|
| Nov 1980 | Jul 1982 | −22.8% | 20 months | 5 months |
| Aug 1987 | Dec 1987 | −26.7% | 4 months | 20 months |
| Aug 2000 | Mar 2009 | −51.8% | 8.6 years | 4.2 years |
| Nov 2021 | Oct 2022 | −24.5% | 11 months | 17 months |
Decade by decade
The 8.71% average is made of 4 very different decades. Real annualised return for each ten years from 1980:
| Decade | Real annualised | $10,000 became |
|---|---|---|
| 1980–1990 | 11.00% | $28,394 |
| 1990–2000 | 14.96% | $40,315 |
| 2000–2010 | -3.10% | $7,299 |
| 2010–2020 | 11.58% | $29,913 |
Best of them: 14.96%. Worst: -3.10%. Anyone who judged the market on a single one of these decades would have drawn the wrong conclusion about the others.
Nominal against real
| Basis | Annualised | $10,000 became |
|---|---|---|
| Real (after inflation) | 8.71% | $485,000 |
| Nominal (before inflation) | 12.19% | — |
The real figure is the one worth planning on. To see what inflation did to a fixed sum over the same stretch, measure the purchasing power of $10,000 from 1980 to today on the same CPI series.
Change the assumptions
This page fixes one set of inputs so it can say something specific. For a different amount, a monthly contribution, a different end date or any start month at all, run the backtest with your own figures. To see how 1980 compares with every other starting point rather than just its rank, look at the full distribution of rolling returns by holding period.
