How does the Latest Month-End Data update file that is available for download from the full weekly update
The Latest Month-End Data update file contains the same data that is sent out on the monthly update CD. This is also the data set we use to generate the passing company lists and performance data that we publish at the Stock Screens area of the AAII Web site.
For most months, the data as-of date for the monthly update file will differ from that of the weekly data update for the same week. When the end of the month is also the last trading day for the week, the data as of dates for both the monthly and weekly update files from that week will be the same, as will the data they contain.
The month-end update file is usually available within two or three days after the end of the month. It is approximately the same size as the full weekly update, so it is intended for users with a high-speed Internet connection (DSL, cable, T1, etc.).
