What this return means
$1,000 invested in Pfizer (PFE) in 2005 is worth $2,620 today. That is a +162.0% gain, a little over 2.6x your money, measured to 2026-06-01.
That is only about 4.6% a year once you compound it across 21.6 years. The same $1,000 in an S&P 500 index fund would be about $9,342 over the identical span, so the index came out ahead by roughly $6,722. 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 2022 at +52.5%, and the worst was 2024 at -35.9%. At its lowest point the position was down about 45% 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 Pfizer 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
$41,605
+61.3% on $25,800 in
Same $25,800, all in at the start
$67,602
+162.0% on $25,800 in
Going all in at the start beat spreading the buys out by $25,998. 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 $14.93 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 PFE split-adjusted monthly closes through June 2026. Past performance does not guarantee future results.
