dxFeed has set 6 December 2026 for a major update to its Morningstar-supplied fundamental equity feed, replacing the earlier target of early November. The 23 October notice is material because it changes both the implementation date and the definitions of fields used by downstream brokers, portfolio analytics and valuation displays. A field name remaining present does not mean its values are directly comparable across the cutover.[1][3]
Morningstar's overhaul changes source-feed structure, field names and the methodology of selected calculated data. dxFeed intends to absorb as many upstream changes as possible, but warns customers to update some receiving systems. The detailed guidance says fundamental data for the majority of stocks may be affected.[1][2]
Confirmed cutover details
| Field or schedule | New treatment | Required check |
|---|---|---|
| Effective date | 6 Dec 2026 | Update old early-November timelineSource 1 |
| Four per-share metrics | Reporting rather than trading currency | Currency alignment before ratiosSource 1 |
| M&A notes | Field retired / empty | Avoid interpreting blank as no eventSource 1 |
| totalReturn / pbvRatio | Methodology revision | Reconcile historical calculationsSource 1 |
Four currency fields require particular care
The provider says salesPerShare, bookValuePerShare, operationsCashFlowPerShare and cashFlowFreePerShare will cease being converted into a stock's trading currency. Instead, these figures will be expressed in the reporting currency. A price-to-book computation that divides a local share price by a per-share book value in a different currency would be economically invalid without conversion. dxFeed has not promised to correct every proprietary calculation customers may have built.[1]
The M&A extension field 'notes' is being retired and will be empty. The historical-return totalReturn field and price-to-book pbvRatio methodology are also changing. Separate corporate-action clarifications should not be misrepresented as new changes: the spin-off subType change was withdrawn, and the description of the existing gross-dividend adjustment treatment was corrected.[1]
What reconciliation must establish
Receivers should compare old and new records by currency, definition and reporting period, not merely by symbol and field label. A sudden jump in a valuation ratio at cutover could be an upstream definition break rather than a movement in the issuer's finances. Where historical values are recalculated, dashboards need to distinguish data revisions from published company restatements.[2][1]
Before the 6 December target, customers should reconcile the latest data dictionary with their own valuation calculations and test records in different reporting and trading currencies. Currency alignment is especially important when a share price and a per-share fundamental are divided to produce a public ratio.[1][2]
