Price $1,715.69 +2,096.79% Close, 9 Oct 2026

Closing prices at the end of each trading day, from 12 Oct 2016. Not a live quote. Adjusted for share splits, so the line has no step at a split; dividends are not added back. P/E and P/FCF are the market value over the last full fiscal year's net income or free cash flow, as public on each day, so they step once a year when the annual report comes out. A hatched band marks a stretch with none: a year of net loss, or of cash burnt.

Five years in brief

Worked out from the figures above, not from a press release
  • Revenue grew 26.1% a year over five years, and earnings per share grew 47.8% a year.
  • The diluted share count fell 3.6% in five years, so buybacks did some of the work per share.
  • Operating margin is up 7.8 points on five years ago, at 14.4%.
  • Profitable in every one of the 10 years on file.
