S&P 500
IndexS&P 500 — companies, valuation & returns
Everything we measure about the S&P 500, computed from public sources and updated daily (as of market close, Sep 4, 2026): 500 companies with their actual index weights, a trailing P/E of 25.9, a dividend yield of 1.06%, and Technology leading the sector mix at 38.2%. Membership is refreshed daily from the current public component roster; weights come from the tracking fund's SEC filing and are rolled forward by price — so every displayed weight is an estimate of today rather than the filed figure; 4 post-filing additions are temporarily estimated from market cap; earnings come from members' own filings via our EDGAR pipeline. Not investment advice.
Members are the S&P 500 constituents chosen by a committee at S&P Dow Jones Indices (size, liquidity, US domicile and profitability rules — not simply the 500 biggest). Membership is refreshed from the current public component table; float-adjusted weights are anchored to the tracking fund's SEC Form N-PORT filing and rolled forward daily by price. Fundamentals come from our SEC EDGAR pipeline. See each page's methodology for details.
Companies, not tickers. S&P 500 counts 500 companies, but a few of them list more than one share class in the index — Alphabet's GOOGL and GOOG, for example. The fund files those as separate rows; we combine a company's classes into a single row and add their weights, so Alphabet appears once at its full index weight rather than twice at half of it. That is why this page says 500 and a list of index tickers elsewhere may run slightly longer.
