NuScale Power Slides 7% as Nuclear Sector Retraces

NuScale Power fell 7% to $8.45, reversing Thursday's legislative gains. Peers Oklo and Centrus Energy also declined as traders trimmed positions.

NuScale Power shares fell 7% to $8.45 in Friday morning trading. This move reversed the gains seen in the previous session. The stock is now down 40% year to date.

The decline is part of a broader sector pullback. Oklo shares dropped 5% to $37.57. Centrus Energy shares fell 3% to $144.66.

Policy Rally Loses Momentum

Thursday's advance followed the House passing the Ratepayer Protection Act. The law requires large energy users to cover grid upgrade costs. Traders had bid up nuclear developers based on this shift.

Friday's selling suggests the initial enthusiasm was tactical. The market is handing back gains rather than re-rating the businesses. The year-to-date drop provides the longer-term context.

Holtec IPO Cancellation Weighs on Sentiment

Holtec International canceled its planned initial public offering on Wednesday. The company cited the market's turn against the AI data center economy. This development adds pressure to the sector's mood.

Sector Rotation Drives the Decline

The Global X Uranium ETF is down 2%. The SPDR S&P 500 ETF Trust is off only 0.1%. This divergence indicates specific selling in nuclear names.

GN auto markets/equities: broad market data confirms this is not a broad risk-off session. It reflects positioning being trimmed after a fast run. Both speculative and cash-generative names are falling together.
