This dataset records the backward-adjustment factors used by exchange-traded funds (ETFs) to adjust market quotations, including the current-period adjustment factor and the cumulative adjustment factor. These factors are solely intended for adjusting historical market data, not for forecasting purposes, and are calculated and adjusted on ex-dividend and ex-rights dates.
