This dataset provides backward-adjustment factor data for adjusting historical stock quotes of Shanghai and Shenzhen stocks, taking the listing price as the benchmark. It includes the ex-dividend and ex-rights date, detailed information of the ex-dividend and ex-rights events, the current adjustment factor, the cumulative adjustment factor, and the corresponding effective date interval. This factor is solely used for adjusting historical market quotations, not for prediction purposes, and is calculated and adjusted on the ex-dividend and ex-rights dates. Records of such adjustment factors only exist on the ex-dividend and ex-rights dates when dividend distribution, rights offering, or non-tradable share reform events take place.
