What this return means
A $1,000 stake in Comcast (CMCSA) from 2000 has grown to $2,717. That is a +171.7% gain, a little over 2.7x your money, measured to 2026-06-01.
That is only about 3.8% a year once you compound it across 26.6 years. By comparison the S&P 500 returned about $8,517 on the same stake, edging out Comcast by close to $5,801. The index compounded at about 8.4% 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 2007 at +59.4%, and the worst was 2008 at -38.6%. At its lowest point the position was down about 50% 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.

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 Comcast at the close of every month from January 2000 through June 2026 means 318 buys and $31,800 contributed over about 26.5 years.
$100/month, dollar-cost averaged
$72,034
+126.5% on $31,800 in
Same $31,800, all in at the start
$86,360
+171.6% on $31,800 in
Going all in at the start beat spreading the buys out by $14,325. 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 $10.84 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 CMCSA split-adjusted monthly closes through June 2026. Past performance does not guarantee future results.
