What this return means

$1,000 invested in Enphase Energy (ENPH) in 2015 is worth $3,974 today. That is a +297.4% gain, a little over 4.0x your money, measured to 2026-06-01.

That is about 12.7% a year compounded, broadly in line with long-run stock market averages. The same $1,000 in an S&P 500 index fund would be about $4,521 over the identical span, so the index came out ahead by roughly $547. The index compounded at about 13.9% 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 2021 at +478.5%, and the worst was 2016 at -80.4%. At its lowest point the position was down about 88% 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 Enphase Energy 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

$117,589

+752.1% on $13,800 in

Same $13,800, all in at the start

+297.4% on $13,800 in

Spreading the buys out beat going all in at the start by $62,745. 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 $5.78 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 ENPH split-adjusted monthly closes through June 2026. Past performance does not guarantee future results.
