To: Fundamental Data Services subscribers

dxFeed would like to inform you about significant upcoming changes from Morningstar, one of our primary providers of fundamental equity data. Morningstar 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.

All these updates are scheduled to take effect at the end of August 2026. At this time, no immediate action is required from you; however, we kindly ask you to monitor our future updates on this matter in order to adjust your systems where necessary. Our team is working diligently to process these updates internally and to keep the data format you receive from us unchanged wherever possible. Minimizing any impact on your side is our top priority. Nonetheless, some adjustments on your end will eventually be necessary, and we will keep you informed and provide ample support.

Details

Examples of changes that will require adjustments:

  • Some enumerations will change. Example: due to the transition from legacy localized datasets to a global schema, the field srcExchange in the Instrument Reference controller will be updated to ensure consistency across regions and products. Currently, it contains values such as (PINX, NYS, ASE, etc.). After the update, its values will be (OTCPK, NYSE, AMEX, etc.). It will not affect the exchange code encoded in dxSymbol.
  • Meeting evolving business requirements and expectations, Morningstar changes its methodology of calculating certain fields. For example, netMargin in the Operation Ratio controller is currently being calculated using “Net Income Available to Common Stockholders” as the key input, influencing the overall ratio outcome. The new process will use “Net Income from Continuing Operations” instead, focusing on a more targeted definition of profitability. This shift accounts for a 33% difference in Net Income inputs between the two systems.
  • The data collection is expanding, and some new fields may be introduced, providing clients with deeper insights.
  • A small number of fields will be retired by Morningstar and, therefore, will become empty.

You can find more information on the dedicated page.

As we work through this upgrade, we will post there the specific changes relevant to you. Additionally, we will periodically inform you about these updates via email.

Effective date

This upgrade will take place at the end of August 2026. We will announce the particular date later. Please be sure to update your systems accordingly.
