Weekly Updates

AAII offers weekly and month-end data updates to Stock Investor Pro subscribers. These files are typically available for download from the Weekly Data Updates section of the Stock Investor area of the AAII Web site by Sunday morning (Central time). You can subscribe to the AAII Stock Investor RSS feed to receive notices when the new weekly update files are available.

There are three weekly update files available: a program/data update, that includes the program installation and the latest data; a partial update that updates price-sensitive data, growth rates, ratios, and earnings estimates; and a full update that will update the entire Stock Investor Pro database.

The program/data update is intended only for those who do not have the program already installed on their system. If you need to install Stock Investor on your computer and have a high-speed Internet connection, visit the Installing Stock Investor area of this wiki.

Here are the steps to access, download, and install the weekly data-only updates:

  • Make sure Stock Investor Pro and/or Stock Investor Utilities are not running on your system.
  • Go to the Weekly Data Updates page of the Stock Investor Pro area of AAII.com:

  • At the Weekly Data Updates page, click on either the Full Weekly Update or Partial Weekly Update button to download a weekly update file. If you have a high-speed Internet connection, we strongly encourage you to use the Full Weekly Update. The Partial Weekly Update is offered for those with a dial-up connection. If you experience problems downloading the selected weekly update file, try clicking on the "Secondary Server" link below the respective update button.
  • Depending on the Web browser you are using, you may be prompted to either Run or Save the update file you selected:

If so, we recommend that you first save the file to your computer, preferably your desktop, so you can easily locate the file when the download is complete.

  • When the download process is complete, double-click on the update file you downloaded (the Partial Update is named update.exe and the Full Update is named fullupdate.exe) to launch the update installation wizard. You may receive a security warning:

You will see a series of windows as Stock Investor Utilities performs database management operations.

  • Lastly, you will be prompted to recalculate the custom fields:

We strongly recommend you always click Yes to this after installing in the program or a data update. Otherwise, the Custom Fields in the program will not reflect the new data you just installed.

  • When the recalculation is complete, the Stock Investor Pro program window will open and you are ready to begin:

si_pro_program_window.gif At the bottom of the Stock Investor Pro program window, you will see the weekly "data as of date." It should correspond to the date of the update you downloaded and installed. You can also see the data as of dates by going to the Help menu in Stock Investor and selecting About. At the bottom of the About window are the data as of dates for the weekly and monthly data installed in Stock Investor Pro.
