Top Losers: The Biggest Stock Declines in North America and Why
October 14, 2026 | ATN Trade & Finance
Wednesday's session delivered a broad-based sell-off after the hotter-than-expected September CPI print, but a handful of names fell far harder than the market — each with its own catalyst layered on top of the macro headwind.
CoreWeave (CRWV) — -15.6%
The AI infrastructure company was the session's most prominent casualty. CoreWeave's bonds traded at distressed levels with market yields approaching 15%, a dramatic move that crystallized concerns about the company's debt load in a higher-for-longer rate environment. CoreWeave carries significant leverage from its rapid GPU data center buildout, and as the 10-year Treasury rose toward 5.28%, the arithmetic of its capital structure became harder to defend. The stock has been volatile since its IPO earlier this year and was among the hardest-hit names in the AI infrastructure cohort. Nebius Group (NBIS), a smaller AI compute company, fell more than 9% in sympathy as contagion spread to the sector.
Oracle (ORCL) — -9%
Oracle's decline compounded an existing overhang. The company's Project Jupiter AI data center in New Mexico has been under pressure since it sent a force majeure notice to its developer — an affiliate of Blue Owl Capital — in September, after a gas pipeline feeding the site was delayed from August 2026 to February 2027. On Wednesday, new reporting indicated Oracle may withdraw a proposed energy service agreement with El Paso Electric for the project, raising fresh questions about whether the 2028 target opening remains achievable. With capital markets already nervous about AI infrastructure execution, the news hit at exactly the wrong moment.
Dell Technologies (DELL) — -8.28%
Barclays downgraded Dell to Equal Weight from Overweight, citing slowing enterprise PC refresh cycles and competition pressures in its infrastructure solutions group. The downgrade arrived on a day when the market was already selling rate-sensitive and capital-intensive tech hardware names, amplifying the move.
Progressive (PGR) — -8.01%
The insurance company reported Q3 results that missed analyst expectations, sending shares down sharply. Progressive had been a strong performer earlier in the year on improving auto insurance margins; the Q3 miss suggests the favorable underwriting environment may be normalizing faster than consensus assumed.
Hewlett Packard Enterprise (HPE) — -8%
HPE also received a Barclays downgrade — the same analyst action that hit Dell — flagging concerns about the server market and AI-related infrastructure spending concentrating with fewer, larger vendors rather than flowing broadly to traditional hardware makers.
Bank of America (BAC) — -5.53%
BAC fell after reporting a Q3 earnings miss on both EPS and revenue, compounded by a $1.2 billion regulatory penalty that cut further into the quarter. EPS came in at $1.08 versus a $1.10 consensus. The stock was one of the few large-cap financial names to fall on an otherwise mixed earnings day for the sector.
What this means for investors: Wednesday's losers split into two camps — rate-casualty names (CoreWeave, Nebius, Oracle) where the CPI print was the accelerant on already-smoldering concerns about leverage and execution, and company-specific stumbles (Dell, HPE, Progressive, BAC) where the macro backdrop made a manageable piece of bad news into a severe one. The common thread is that there is no margin for error in this rate environment.
