Why Is NUSCALE PWR CORP A (SMR) Stock Up Today?

Why SMR stock is up today

NuScale Power Corp A (SMR) surged 15.26% to $11.18 on Monday, marking its best single-day performance in over four months. The stock's sharp rise followed a wave of unusual options activity and a broader market shift toward small modular reactor (SMR) stocks. Despite a challenging earnings history and a recent selloff by key insiders, retail and institutional interest appears to be building.

What Happened

NuScale Power’s stock climbed to $11.18, a price not seen since early April. The move came amid a broader uptick in nuclear energy stocks, with Oklo also rising sharply. A surge in call options activity, totaling $1.8 million in premium, highlighted growing bullish sentiment. Background reports noted a recent partnership with MillenniTEK to fabricate boron-oxide pellets for NuScale’s emergency core cooling system, as well as speculation about AI integration potentially boosting efficiency. However, the company remains unprofitable, with a year-to-date revenue decline of 81% and a trailing twelve-month EPS of -1.54.

What The Data Shows

Over the past eight trading sessions, NuScale’s stock has gained 15.3%, rising from $9.64 to $11.10. In the last 36 hours, the stock printed four notable options trades, with the largest being a $1.0 million call options print. The 52-week tape showed 36 fresh 52-week highs and two fresh lows on September 8. Meanwhile, insiders have sold five times in the last 90 days, totaling $836,000, with the most recent sale occurring on August 28.

What To Watch

The next key event for NuScale investors will be the company’s next earnings report. Until then, investors should monitor the breadth of coverage and whether the recent rally attracts broader institutional support.
