The rise and fall of market giants
27 companies have held a top-10 spot in the US stock market since 2010 — and only AAPL and MSFT and GOOGL never left. Below, every giant's top-10 rank year by year, then each one's share of total large-cap market value: watch NVDA swell from 0.1% to 6.8% while XOM fades from 3.5% to 0.8%.
Who held each rank, 2010–today#
Every swap at the top is a line crossing. The average giant holds a top-10 spot for about 6.1 years of the 17 charted — hover a rank to trace that company's full path.
Each line is one company's market-cap rank, sampled every January (last column = the latest month). Ranks below #10 collapse into the shaded "10+" bucket. Hover a rank to trace a company's full path.
Every giant's share of the market#
The same story as weights instead of ranks: each band is one giant's share of total large-cap market value, month by month. Hover any band for the company, its weight and its rank that month.
Methodology#
A company qualifies as a "giant" if it ranked among the 10 largest US-listed companies by full market cap in any month since 2010. Caps are reconstructed from month-end prices and SEC-filed share counts (normalized for splits) across the ~500 US large caps we track — approximately the current S&P 500 membership plus a few large US listings outside the index, foreign ADRs excluded. Weights divide by that universe's total market value, so they sit slightly below official float-adjusted index weights, and heavy spin-off histories (GE, AT&T) are undercounted in early years. See how top-heavy the market is for the concentration view of the same data. Not investment advice.
FAQ
- Which companies have been in the stock market's top 10 the longest?
- Apple Inc. (AAPL) and Microsoft Corporation (MSFT) and Alphabet Inc. Class A (GOOGL) have held a top-10 spot in every single month since 2010. AAPL has spent the most time as the single largest company — about 11 of the last 17 years.
- Which giants dropped out of the top 10?
- 27 different companies have held a top-10 spot since 2010; as of July 2026, 17 of them are no longer there, including XOM, BRK-B, JNJ, WMT, JPM, PG, CVX, WFC. The classic fades: Exxon Mobil Corporation went from 3.5% of the market in 2010 to 0.8% today.
- Do the biggest stocks stay on top?
- Rarely for long — that's the point of this chart. Of the top 10 of 2010 (Exxon, Microsoft, Walmart, Google, IBM, Chevron, GE and peers) only a few remain, and the energy-and-industrials heavyweights gave way almost entirely to technology. Academic work on the "biggest stock" effect finds the #1 company has historically underperformed the market over the following decade — size is easier to reach than to defend.
