What this return means
Holding Amkor Technology (AMKR) from 2015 multiplied a $1,000 stake into $14,600. That works out to +1360.0%, about 15x the original stake, as of 2026-06-01.
In compound terms that is roughly 26% a year, well above what a broad index has historically returned. The same $1,000 in an S&P 500 index fund over the same span would be about $4,521, so Amkor Technology beat the index by roughly $10,079. The index compounded at about 13.9% a year over that period.
The path was not smooth. The best single year was 2017 at +53.3%, and the worst was 2019 at -20.5%. These figures use split-adjusted closing prices and exclude dividends, taxes, trading fees, and inflation, so a real after-tax result would differ.

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 Amkor Technology at the close of every month from January 2015 through June 2026 means 138 buys and $13,800 contributed over about 11.5 years.
$100/month, dollar-cost averaged
$103,139
+647.4% on $13,800 in
Same $13,800, all in at the start
$201,457
+1,359.8% on $13,800 in
Going all in at the start beat spreading the buys out by $98,317. 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 $11.52 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 AMKR split-adjusted monthly closes through June 2026. Past performance does not guarantee future results.
