Top-of-mind questions for buyers
What does one price or volume adjustment factor represent in this dataset?
Each factor is a numeric multiplier tied to a corporate event that changed a security's price or volume, such as a split or dividend. You apply it to raw price or volume series to normalize them forward or backward. Each factor links to a persistent security identifier so it traces through ticker changes.
What is not included in this free file compared with paid adjustment factor data?
This free file covers one 2020 month of Basic Adjustment Factors, giving the factor, effective date, and adjustment reason. It does not include full history back to 2007, daily automated updates, or the added detail found in the detailed, cumulative, or daily cumulative factor datasets. It is a sample of the format.
Does this free listing meter usage or charge for downloads?
No. The listing is free, so there is nothing to meter and no download charges apply. You receive a single fixed CSV file for one 2020 month. There are no tiers, quantities, or usage add-ons that could change your cost.
