NuScale Power shed nearly 10% in regular trading, erasing close to $200 million in market value and leaving very little margin for error on future down days.

For investors following the small modular reactor theme, the sub-$5 handle matters psychologically as much as technically. The stock had been trading above that level coming into the session, and losing it removes a layer of support that speculative buyers had been leaning on.
