Market-cap change uses historical capitalization records. Share-price returns are a different series — they can diverge when the share count changes. Those returns are not a CAGR until you pick a start value, an ending value, and years. CAGR calculator. Market cap vs. stock price.
Year-end values and the chart both come from historical market-cap records, not from applying today's share count to past prices. Latest historical observation October 2, 2026. Ranking headline cap is the snapshot figure as of October 3, 2026.
