What size tells you - and what it does not
The largest companies are usually established, widely followed and easy to trade, and an index fund owns them in proportion to their size. Size does not tell you whether a share is cheap, whether the business will keep growing or how much the price can still rise.
Same company, several tickers
Some companies have more than one share class, for example Alphabet (GOOGL and GOOG) or Berkshire Hathaway (BRK.B and BRK.A). The screener shows one row per company by default and marks the other classes, so a company is not counted twice in your top 10.
Using the screener
The Largest companies profile ranks every company worth at least 100 billion by market value; the first ten rows are the top 10. Add growth, P/E and dividend columns to see how the giants differ.
Try it in the screener
The Largest companies profile shows the biggest listed companies by market value. It is a learning example, not a recommendation.
