List of companies in the S&P 500 (Standard and Poor's 500). The S&P 500 is a free-float, capitalization-weighted index of the top 500 publicly listed stocks in the US (top 500 by market cap). The dataset includes a list of all the stocks contained therein and associated key financials such as price, market capitalization, earnings, price/earnings ratio, price to book etc. ## Data Information on S&P 500 index used to be available on the [official S&P website][sp-home] but until they publish it back, Wikipedia is the best up-to-date and open data source. * Index listing - see `data/constituents.csv` extracted from Wikipedia's [List of S&P 500 companies][sp-list] * Constituent financials - see `data/constituents-financials.csv` (source via Yahoo Finance) * Scatter plot data - see `data/scatter-data.csv` (derived from `constituents-financials.csv`; companies with positive P/E ≤ 100, market cap in USD billions) Notes: * In `constituents-financials.csv`, Market Cap and EBITDA are in raw USD (e.g. `83294183424` ≈ $83.3 billion). In `scatter-data.csv`, the `market_cap_b` column is in USD billions. * Some financial fields (e.g. Dividend Yield, Earnings/Share, Price/Book) may be absent for certain companies where Yahoo Finance does not report a value.
