Ultumus and ActiveViam plan ETF composition data inside Atoti

Ultumus and ActiveViam announced a partnership on 20 October to make ETF and index composition data available within Atoti. The planned connection links a specialist source of constituent data with the platform in which portfolio teams calculate exposures.[1]

The firms describe validated, versioned data feeding existing risk workflows. That addresses a practical source of error: a portfolio’s valuation date, an index reconstitution date and an ETF holdings snapshot may differ. Using the wrong version can change the securities and weights feeding the analysis.[1][2]

Looking through the fund wrapper

An ETF position is a holding in one instrument, but analysing its concentration may require examining the securities underneath. Combining that look-through with direct holdings can expose overlaps that are not apparent from the fund name. Historical analysis also needs the composition that applied at the time, rather than today’s constituents applied retrospectively.[1][2]

Ultumus supplies the composition inputs; Atoti supports their use in analytical workflows. The institution still supplies its own positions and determines how exposures, currencies and stress scenarios are calculated. A common input file helps reconcile the starting data without prescribing one universal risk model.[1][2]

Availability remains a planned step

The release uses future-tense language and does not identify a customer already running the new feed in production. It gives no launch date, price or measured reduction in data errors. The development is the agreed route from the constituent-data provider into Atoti, with production outcomes still to follow.[1]
