Details
Data for most members of the S&P 500 are present. Some securities have been omitted due to data processing complexities. For example, securities for companies with multiple share classes have been omitted in the current version.
Values for shares outstanding and stockholders' equity downloaded from EDGAR may be inaccurate due to XBRL parsing issues.
Full code for reconstructing the dataset can be found in the pystrand repository.
