What this return means
Kratos Defense (KTOS) is one of the losers in this dataset. That stake is worth $585 as of 2026-06-01, a -41.5% move that left you with less than you started with after 21.6 years.
That averages out to -2.5% a year, meaning the position shrank in compound terms across the 21.6-year window. By comparison the S&P 500 returned about $9,342 on the same stake, edging out Kratos Defense by close to $8,757. The index compounded at about 10.9% 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 2017 at +158.3%, and the worst was 2007 at -56.0%. At its lowest point the position was down about 96% 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 Kratos Defense 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
$114,681
+344.5% on $25,800 in
Same $25,800, all in at the start
$15,098
-41.5% on $25,800 in
Spreading the buys out beat going all in at the start by $99,583. That happens when the price spent time below where it began, so averaging in caught the cheaper months. Averaging in also meant an average buy price of $11.22 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 KTOS split-adjusted monthly closes through June 2026. Past performance does not guarantee future results.
