As we informed you at the beginning of April regarding the upcoming Fundamental Equity Data upgrade, Morningstar, one of our primary providers of fundamental equity data, is currently undergoing a comprehensive overhaul of its data feed, which includes extensive changes to field names, feed structure, and updates to the methodology used for calculating certain fields. These changes will affect fundamental data for the majority of stocks.

With this announcement, we would like to share some more updates on this topic.

Details

The release of this new data format will take place on 6 December 2026. This timeframe will give our clients as much time as possible to review the changes and prepare for them.

Please review the latest changes on our dedicated page and make adjustments on your end if necessary. Here is a short overview of what has changed since the previous announcement.

A new section has been added: New Data Dictionary Version. The new version of the Data Dictionary will take effect in December, along with the upcoming Fundamental Equity Data Upgrade. It covers data additions related to this upgrade, plus adds some clarifications in the definitions of various fields.

There are some new changes that might require adjustments on your side:

Corporate Actions:

  • Populating the field ‘subType’ with the value SP when type=SPINOFF was removed from the scope of the upgrade. Therefore, nothing changes for you.
  • Description of the ‘taxRate’ field was corrected. Previously, it mentioned that the ‘adjustmentValue’ field contains the net dividend amount for cash dividends. Now, it correctly states that the ‘adjustmentValue’ field contains the gross dividend amount for cash dividends. That’s how it was in the old format, and that’s how it remains in the new format.

Merger and Acquisition:

  • A change is added: the extension field ‘notes’ is retired and will be empty from now on.

Valuation Ratio:

  • A note is added that Morningstar will no longer convert 4 fields (‘salesPerShare’, ‘bookValuePerShare’, ‘operationsCashFlowPerShare’, and ‘cashFlowFreePerShare’) to the trading currency; from now on, they will be expressed in the reporting currency.

Changes in methodology:

  • New individual methodological changes added for Historical Return – totalReturn and Valuation Ratio – pbvRatio attributes.

Effective date

This upgrade will take place on 6 December 2026. Please be sure to update your systems accordingly.
