Why SMR stock is up today
NuScale Power Corp A (SMR) surged 10.56% to $9.18 in early trading on Thursday, driven by a mix of market momentum and recent developments in the small modular reactor (SMR) industry. The stock opened with a 2.0% gap up and reached an intraday high of $9.21 before consolidating near its session peak. The move followed a wave of news highlighting growing global interest in SMR technology and a recent engineering milestone for NuScale.
What Happened
NuScale Power recently overcame a major engineering challenge in the development of its small modular reactor, bringing it closer to commercial deployment. This progress was highlighted in a report from The Motley Fool, which emphasized the company's technical advancements. At the same time, the European Investment Bank announced increased investment in SMRs, positioning NuScale and other firms like Oklo to benefit from expanding international demand. These developments fueled optimism in the market, especially as the SMR sector is increasingly seen as a key player in clean energy and energy security. However, the stock faced headwinds earlier in the week after UBS downgraded NuScale to "Sell," citing regulatory hurdles and rising competition.
What The Data Shows
The stock opened at $8.47 and climbed steadily throughout the session, closing near its high. Trading volume reached 19.5 million shares, or 0.6 times the 3-month average, suggesting moderate but growing participation. The stock has been volatile, having fallen 20.1% over the past 8 sessions from $11.10 to $8.87. NuScale remains unprofitable, with a trailing twelve-month revenue decline of 81.0% and an EPS of -1.54. The stock currently trades within its 52-week range of $7.21 to $57.42. Recent insider transactions show 6 sales totaling $1.0 million in the last 90 days, with no insider purchases recorded.
What To Watch
NuScale Power has no scheduled earnings in the near term. Traders and investors will likely monitor the breadth of coverage and sentiment shifts, particularly as the SMR market continues to evolve with regulatory and geopolitical developments.
