S&P 500 — companies, valuation & returns
Everything we measure about the S&P 500, computed from public sources and updated daily (as of market close, Oct 20, 2026): 500 companies with their weights in the tracking fund, a trailing P/E of 26.1, a dividend yield of 1.07%, and Technology leading the sector mix at 38.1%. 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; 10 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). From SPY's SEC Form N-PORT filing — the fund's own report of what it holds — rolled forward by ChartRow from daily price moves. Membership is refreshed daily from the public component table. They are ChartRow's estimates, not SPY's actual weights: the fund trades and rebalances between filings, so its real weights can differ materially, and a figure can be stale or wrong. They are not S&P Dow Jones Indices' official index weights, and may differ from them. 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 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.
