What this return means
Putting $1,000 into Amkor Technology (AMKR) in 1998 returned $8,936. That is a +793.6% gain, a little over 8.9x your money, measured to 2026-06-01.
That is about 8% a year compounded, broadly in line with long-run stock market averages. By comparison the S&P 500 returned about $12,380 on the same stake, edging out Amkor Technology by close to $3,444. The index compounded at about 9.2% 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 2004 at +255.6%, and the worst was 2005 at -74.5%. At its lowest point the position was down about 93% 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 Amkor Technology at the close of every month from May 1998 through June 2026 means 338 buys and $33,800 contributed over about 28.2 years.
$100/month, dollar-cost averaged
$379,842
+1,023.8% on $33,800 in
Same $33,800, all in at the start
$301,991
+793.5% on $33,800 in
Spreading the buys out beat going all in at the start by $77,851. 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 $7.66 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.
