What this return means
$1,000 in Arista Networks (ANET) in 2015 grew to $43,062. That works out to +4206.2%, about 43x the original stake, as of 2026-06-01.
That is a compound rate of about 38.4% a year, an extreme pace that few holdings sustain for 11.6 years. The same $1,000 in an S&P 500 index fund over the same span would be about $4,521, so Arista Networks beat the index by roughly $38,541. The index compounded at about 13.9% a year over that period.
The path was not smooth. The best single year was 2018 at +193.4%, and the worst was 2019 at -22.1%. 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 Arista Networks 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
$178,134
+1,190.8% on $13,800 in
Same $13,800, all in at the start
$595,011
+4,211.7% on $13,800 in
Going all in at the start beat spreading the buys out by $416,877. 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 $13.16 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 ANET split-adjusted monthly closes through June 2026. Past performance does not guarantee future results.
