What this return means
$1,000 placed in US Aggregate Bond (AGG) in 2005 is worth $1,897 now. The total return is +89.7% over 21.6 years, as of 2026-06-01.
That is only about 3% a year once you compound it across 21.6 years. A plain S&P 500 fund would have grown that $1,000 to about $9,342 instead, beating US Aggregate Bond (AGG) by around $7,445. The index compounded at about 10.9% a year, a reminder that a single stock can lag a basket of them.
The path was not smooth. The best single year was 2020 at +9.7%, and the worst was 2023 at -8.3%. These figures use split-adjusted closing prices and exclude dividends, taxes, trading fees, and inflation, so a real after-tax result would differ.
This is historical math, not financial advice. Past performance does not guarantee future results.
What if you invested $100 a month instead?
Most people do not drop a lump sum in on day one. They add a fixed amount every month. Putting $100 into US Aggregate Bond (AGG) at the close of every month from January 2005 through June 2026 means 258 buys and $25,800 contributed over about 21.5 years.
$100/month, dollar-cost averaged
$33,701
+30.6% on $25,800 in
Same $25,800, all in at the start
$48,946
+89.7% on $25,800 in
Going all in at the start beat spreading the buys out by $15,245. That is the usual result when a stock trends up: each monthly buy pays a higher price than the last, so the average cost climbs. Averaging in also meant an average buy price of $75.52 per share across the whole stretch, so the monthly buyer never had to time a single low. Neither number counts dividends, taxes, or trading costs.
Illustrative fixed $100/month example, not a recommendation. Figures are computed from AGG split-adjusted monthly closes through June 2026. Past performance does not guarantee future results.
