What this return means
20+ Year Treasury (TLT) turned $1,000 into $1,503 since 2010. The total return is +50.3% over 16.6 years, as of 2026-06-01.
That is only about 2.5% a year once you compound it across 16.6 years. The same $1,000 in an S&P 500 index fund would be about $9,294 over the identical span, so the index came out ahead by roughly $7,790. The index compounded at about 14.4% a year, a reminder that a single stock can lag a basket of them.
The year-by-year record shows how bumpy the ride was. The best single year was 2012 at +37.8%, and the worst was 2023 at -23.0%. At its lowest point the position was down about 35% from an earlier high. These figures use split-adjusted closing prices and exclude dividends, taxes, trading fees, and inflation, so a real after-tax result would differ.
None of this is a recommendation. It is a record of what already happened, and 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 20+ Year Treasury (TLT) at the close of every month from January 2010 through June 2026 means 198 buys and $19,800 contributed over about 16.5 years.
$100/month, dollar-cost averaged
$19,236
-2.8% on $19,800 in
Same $19,800, all in at the start
$29,766
+50.3% on $19,800 in
Going all in at the start beat spreading the buys out by $10,530. 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 $88.60 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 TLT split-adjusted monthly closes through June 2026. Past performance does not guarantee future results.
