Live Update At 12:33:51 EDT: On Thursday, September 17, 2026 NuScale Power Corporation stock [NYSE: SMR] is trending up by 10.51%! Discover the key drivers behind this movement as well as our expert analysis in the detailed breakdown below.

Quick Financial Overview

NuScale Power Corporation, trading as SMR, is acting like a classic story stock: big technology promise, heavy losses, and fast moves on headlines. Revenue over the last year was about $31.5M, but SMR is nowhere near profitability. The company posted a Q2 net loss of roughly $50.1M and an operating loss near $64.0M. Margins are deeply negative, which tells traders this is still a pre-commercial build‑out phase, not a cash machine.

On the plus side, SMR’s balance sheet is strong for now. Cash and short-term investments sit above $1.0B, with cash alone around $766.5M and essentially no debt. Current ratio near 38 means NuScale can fund years of burn at the present pace, though that assumes no major cost surprises. Book value per share is about $4.80, versus a stock price in the high single digits, so traders are paying a premium for future reactor deployments.

More Breaking News

The daily chart shows that premium trades with emotion. Over the last couple of weeks, SMR ran from sub-$9 to above $11, then dumped back toward $8–$9. Intraday on the latest session, SMR ground higher from the mid‑$8.40s to over $9.15, a slow trend day rather than a face‑ripping squeeze. For active traders, this mix of solid cash, big losses, and reactor optionality sets up a news‑driven, momentum‑heavy tape.

Why Traders Are Watching SMR

SMR remains on radar because NuScale Power sits at the crossroads of nuclear, AI, and energy transition hype. The core story is its small modular reactor platform, already approved by the NRC. What changed recently is proof the company is inching from drawings to hardware. NuScale and materials partner MillenniTEK have now fabricated first-of-a-kind boron‑oxide pellets for the passive emergency core cooling system. That’s not sexy headline material to the average person, but for traders following SMR, it is a clear de‑risking step.

Those pellets are a key safety component. Getting them produced is another box checked on the path to commercial deployment and real revenue. It signals SMR is building an actual supply chain, not just issuing slide decks.

At the same time, NuScale is leaning hard into AI. The company is deploying nuclear‑specific AI tools from Nuclearn and NPX’s AtomAssist to handle engineering and knowledge management. Early results suggest up to an 80% reduction in time to find critical engineering data. That kind of efficiency matters in a regulated, document‑heavy field like nuclear. For SMR traders, it says management is trying to compress timelines and lower execution risk.

The market initially liked it. On 2026/08/25, SMR shares jumped around 8–9% on the AI news, outperforming a weak energy sector weighed down by lower oil prices. Several intraday spikes lined up with AI headlines as traders piled into the story. But this is still a battleground name. Texas Capital later cut its SMR price target from $15 to $12, even while keeping a Buy rating and pointing to stronger balance sheets across the nuclear group. That’s a reminder: the Street now sees value, but not at any price, and Oklo’s mention as the preferred name underscores rising competition.

Conclusion

For active traders, SMR is the kind of story that rewards preparation and punishes hope. On the one hand, NuScale Power continues to check important boxes: NRC‑approved SMR design, real hardware progress with MillenniTEK’s boron‑oxide pellets, and AI tools from Nuclearn and NPX aimed at speeding engineering work. The balance sheet is loaded with cash and basically no debt, giving NuScale time to execute. Those are the ingredients long‑biased traders want to see in a speculative nuclear name.

On the other hand, the tape is brutal. After the August AI spike, SMR rolled over hard. Recent sessions saw drops of 8.5% to $9.34 and then another 12.5% to $8.94 on 2026/09/11, with no fresh negative fundamentals in the headlines. That smells like profit‑taking, positioning resets, and sentiment whiplash rather than a broken thesis. The intraday 5‑minute chart shows controlled grinding moves, not chaos, which creates opportunities for disciplined day trades around key levels near $8.50–$9.50.

For swing traders studying SMR, the key is to respect both sides of the story: real progress and real risk. As Tim Sykes loves to remind traders, “The market doesn’t care about your opinion, only your preparation — study the pattern, know your risk, and be ready to cut fast.” That mindset lines up with the day‑to‑day approach many momentum specialists emphasize. As Tim Bohen, lead trainer with StocksToTrade says, “I focus on momentum that’s visible right now. Speculation on future moves is outside my playbook.” NuScale Power Corporation will keep throwing headlines at the market. Your edge is how well you read the chart when those headlines hit.
