The Roundhill Neocloud ETF and three U.S.-listed AI computing companies fell before Thursday’s market open, a broad retreat led by Nebius Group N.V., whose shares dropped 20.1%.
The fund declined 12.5%. CoreWeave Inc. lost 13.6%, while IREN Limited fell 8.1%, giving it the smallest decline among the three companies. The ETF’s loss sat between CoreWeave’s and IREN’s, while Nebius recorded the largest drop.
Separately, Nvidia Chief Financial Officer Colette Kress has been tapped to serve as interim CEO after the chief executive resigned.
EconoTimes previously reported a smaller decline in the same three stocks during Monday’s U.S. session: Nebius was down 5%, CoreWeave 4.1% and IREN 3.3%. The latest falls were larger for all three names. The earlier readings were taken after the opening bell; Thursday’s losses were recorded before trading began. The two updates therefore capture separate points in the U.S. trading day, rather than a direct comparison at a matching time. Both accounts captured partial trading snapshots.
