Daily Nuclear & Uranium Market Recap
Wednesday, March 18, 2026
Market Overview
The nuclear and uranium complex split sharply today. Regulated and merchant nuclear power names rallied, while most uranium producers, fuel cycle names, and SMR or advanced reactor plays traded lower. Uranium rose to $86.50/lb on March 17, up 0.41% day over day, and is down only 2.64% over the past month while still 34.53% higher than a year ago, based on CFD pricing that tracks the benchmark market. Uranium Spotlight last reported spot at $86.80/lb as of March 10, essentially unchanged week over week, with spot activity moderating after a very strong start to 2026 but term contracting and conversion prices continuing to firm. The commodity backdrop remains stable; today’s moves were equity positioning and factor driven.
Key Equity Movers, Winners
Vistra (VST) closed at $169.89, plus 3.38% on 3.7M shares. Recent coverage has highlighted Vistra as one of the top utility or power names for 2026, with Wells Fargo reiterating a Buy rating and a $236 price target, implying about 40% upside. A separate note flagged the company’s fleet expansion through acquisition of seven natural gas facilities and strong analyst support as drivers of today’s strength.
Talen Energy (TLN) closed at $337.54, plus 3.18% on 706.4K shares, and Constellation (CEG) closed at $317.00, plus 3.03%, both participating in the power and clean energy bid. The IPP trio (VST, TLN, CEG) is increasingly behaving like a “nuclear plus grid stability” trade, distinct from upstream miners.
Curtiss Wright (CW) closed at $690.94, plus 1.67% on 267.9K shares after trading as high as 788.07 intraday, another wide range day in a normally steadier defense exposure.
Mirion (MIR) closed at $19.50, plus 1.25% on 4.7M shares, grinding higher despite another large intraday range.
BWX Technologies (BWXT) closed at $208.94, plus 0.70% on 1.1M shares, extending its steady climb. Zacks recently highlighted BWXT as one of the “best nuclear energy stocks to buy,” with about 16% projected 1 year sales growth and double digit EPS growth.
Core Uranium and Fuel Cycle
Most upstream and royalty names drifted lower, despite uranium itself holding in the high $80s equivalent:
Cameco (CCJ) closed at $109.99, minus 1.37% on 2.7M shares, slipping back toward the lower end of its recent band. Cameco’s own pricing table still shows February spot at $86.95/lb, up sharply versus $65.03 a year earlier, underscoring how much CCJ has de rated versus the commodity since late February.
Denison (DNN) closed at $3.65, minus 1.62% on 29.6M shares, another heavy volume session as the stock continues to digest last week’s FID and 2025 results. Recent notes characterized the action as “sell the news” around the Phoenix ISR decision and approximately $600M capex plan, with the market now focused on financing structure and execution toward an expected mid 2028 first production.
NexGen (NXE) closed at $11.74, minus 1.68% on 6.3M shares. Zacks and others still highlight Rook I as a key long term source of up to about 30M lbs per year of uranium once in full production early next decade, but near term trading remains tied to beta and sentiment.
Uranium Energy (UEC) closed at $13.62, minus 2.64% on 10.3M shares, giving back part of the bounce that followed last week’s Q2 print. That print confirmed $20.2M revenue, $10M gross profit, sales of 200k lbs at $101/lb versus an $80.76/lb quarterly spot average, and $818M in liquid assets with no debt and 1.456M lbs of inventory. Investing.com and other outlets have since argued that UEC’s bull case is “starting to look real” on the back of this balance sheet and price leverage, but today’s tape shows macro and factor flows still dominating.
LEU closed at $208.69, minus 2.30% on 560.5K shares, stepping back after recent gains. Zacks last week called LEU down 19% in three months and asked whether it was time to buy the dip, underscoring the tug of war between its $3.8B backlog and post earnings volatility.
Uranium Royalty (UROY) closed at $3.59, minus 3.23% on 1.5M shares, moving with the miner basket.
enCore (EU) closed at $1.92, minus 3.03% on 2.2M shares, still under pressure despite its recent year end update showing 655k lbs sold at $65.89/lb and a cleaner balance sheet.
Ur Energy (URG) closed at $1.37, minus 5.52% on 16.5M shares, continuing to feel the impact of H.C. Wainwright’s recent target cut to $2.30 on dilution and 2025’s negative 200% gross margin and $74.9M net loss. MarketBeat also flagged URG’s sharp drop, framing near term sentiment as fragile.
SMR, Advanced Reactors, Isotopes, and AI Adjacents
Bloom Energy (BE) closed at $156.39, minus 2.29% on 8.5M shares, consolidating after last week’s violent swings. Yahoo and others have noted that BE’s 285% 2025 run and continued climb in early 2026 leave it “pricey after an outsized rally,” even as AI and data center power demand support its long term story.
NuScale Power (SMR) closed at $12.01, minus 3.46% on 15.7M shares, slipping after yesterday’s bounce. Recent pieces still cite SMR as one of two nuclear stocks to buy for long term AI and data center driven demand, alongside GE Vernova, but acknowledge long and uncertain timelines.
Oklo (OKLO) closed at $57.19, minus 5.52% on 11.9M shares, slipping further below the $60 pivot. The name remains deeply down from its 52 week highs but is moving in tandem with SMR and other high duration plays.
Nano Nuclear (NNE) closed at $21.54, minus 0.65% on 2.0M shares.
Lightbridge (LTBR) closed at $11.10, minus 3.81% on 671.2K shares.
ASP Isotopes (ASPI) closed at $4.66, minus 6.24% on 3.9M shares, extending last week’s sharp reset. A recent valuation note highlighted that ASPI experienced a nearly 10% single day drop earlier in March and remains down about 6% year to date even after a roughly 25% one year total return, pointing to the stock’s sensitivity to sentiment and capital raises despite long term nuclear fuel and isotope MOUs.
NuScale AI (NUAI) closed at $5.34, minus 10.71% on 7.3M shares, the worst performer today. This follows several big up days; NUAI continues to trade as a momentum vehicle tied to AI sentiment.
Uranium Market Backdrop
Spot and futures: Uranium rose to $86.50/lb on March 17, up 0.41% from $86.15 the prior day, and is now down only 2.64% over the past month while sitting 34.53% above its level a year ago, according to CFD pricing. The front month futures curve is effectively flat in the high $80s equivalent, with Barchart data showing recent closes in the mid to upper $80s over the past month.
Context: As Uranium Spotlight emphasized in its March 10 video, the spot price closed that week at $86.80/lb, essentially unchanged from $86.85 at the start of the week, after a prior pullback from the high $90s following a strong rally earlier in 2026. Roughly 146 spot transactions totaling about 16.3M lbs U33O88 had already been recorded by early March, more than 70% higher than the same period in 2025, even as weekly activity has cooled slightly in recent weeks. Long term, Crux and Sprott continue to argue that rising demand from new reactors in India and China, AI driven electricity needs, and constrained supply from major producers set the stage for another leg of the bull market once this consolidation phase ends.
SEQH Desk View
Today’s message from the tape is that capital is rotating back into contracted and merchant nuclear power while continuing to de risk exposure to upstream and high duration names. VST, TLN, and CEG up 3 to 3.4% on a day when CCJ, DNN, UEC, LEU, UUUU, SMR, OKLO, URG, and ASPI are all red tells you investors are prioritizing cash flow visibility and balance sheet strength over commodity and development optionality.
The uranium commodity itself quietly grinding up to $86.50/lb while equities leak lower is the same divergence we have been flagging all month. At some point, either spot breaks down toward the low $80s, or the miners and fuel cycle names catch up. With contracting and conversion indicators still firm, and FIDs like Phoenix ISR now officially in motion, the burden of proof remains on the bear case that the cycle has meaningfully cracked.
From a positioning standpoint, this environment continues to reward a barbell: at one end, nuclear IPPs and BWXT for defensive exposure, and at the other, selective high quality uranium and fuel cycle names like CCJ, UEC, LEU, and DNN that can ride the next leg higher in spot and term prices. The names in the middle with weak balance sheets, heavy dilution, or very long dated commercialization paths (URG, ASPI, some SMR and AI adjacents) are where the market is taking its pound of flesh right now.
