Largest US Stock Movers — September 15, 2026
Query: top movers today · data as of 2026-09-15
Rebuilt the largest-movers screen for the 2026-09-15 session: a Top Gainers table (25 names, sorted by 1D return descending, led by a quantum-theme spike and a broad off-cycle health care/life-science tools cluster plus analog semis Skyworks and Qorvo at new highs) and a Top Losers table (25 names, sorted ascending, dominated by consumer discretionary restaurants/specialty retail, pre-revenue biotech de-risking, and policy-hit crypto-linked financials Circle and Coinbase). Both tables carry Symbol, name, sector, industry, 1D/1M/6M returns, market cap, relative volume, momentum potential, P/E TTM, days since earnings, % from 52-week high and technical setup, with new per-row qualitative commentary and a takeaway narrative on the single-name, non-sector nature of the tape.
Session-level movers for September 15, 2026. The tape was narrow and defensive: decliners outpaced advancers roughly two-to-one and only about a third of names still hold their 50-day average, so both lists are dominated by idiosyncratic single-name news rather than broad sector rotation. Gainers cluster in off-cycle health care (life-science tools, diagnostics, biotech) and analog semis — the market paying for output rather than the AI hardware supply chain — while the loser side is a crowded de-rating in consumer discretionary restaurants/retail, health-care price reactions, and policy-sensitive crypto-linked financials. Energy-linked names appear on both sides, a sign of how violent single-session moves are in that complex right now.
Top Gainers — September 15, 2026
| Symbol | Security Name | Sector | Industry | 1D Return | 1M Return | 6M Return | Market Cap | Relative Volume | Momentum Potential | P/E (TTM) | Days Since Earnings | % From 52W High | Technical Setup | Comments |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| HQ | Horizon Quantum Holdings Ltd. - Class A Ordinary Shares | Information Technology | Software - Infrastructure | 27.66% | -22.31% | — | 7.124e+08 | 5.2905 | — | — | 42 | -65.62% | Symmetrical triangle | Quantum-computing shell of a story: the bounce is technical, not fundamental, and the name sits deep in a quantum complex that has been one of the month's worst-performing themes. Revenue-less, so this is pure risk appetite. |
| BBNX | Beta Bionics, Inc. - Common Stock | Health Care | Medical Devices | 14.94% | 9.45% | 76.91% | 8.652e+08 | 1.4214 | 43.3 | — | 47 | -39.89% | Uptrend | Automated insulin-delivery specialist; the move extends a re-rating as its next-gen device ramps and reimbursement groundwork builds. Still modestly sized, so liquidity can amplify both directions. |
| SWKS | Skyworks Solutions, Inc. | Information Technology | Semiconductors | 13.55% | 29.27% | 64.46% | 1.354e+10 | 2.0977 | 49.4 | 46.63 | 48 | 0.00% | Uptrend | Analog/RF chip maker at a fresh 52-week high — this is the 'old' semiconductor cycle, not the AI accelerator trade. Handset content and handset OEM inventory restocking plus M&A speculation in the analog space are the drivers; multiple is low single digits on forward earnings. |
| FTRE | Fortrea Holdings Inc. | Health Care | Biotechnology | 13.33% | 13.33% | 112.84% | 1.876e+09 | 1.3414 | 68.9 | — | 48 | -4.69% | Uptrend | Clinical research organization spun out of Labcorp, still working through a profitability reset. Any improvement in biopharma R&D spending is high-margin operating leverage for CROs; note the very high structural volatility score. |
| ARQQ | Arqit Quantum Inc. - Ordinary Shares | Information Technology | Software - Infrastructure | 12.15% | -25.00% | 30.55% | 3.179e+08 | 1.4859 | — | — | — | -68.65% | Symmetrical triangle | Post-quantum encryption vendor. The volatility is entirely narrative-driven — quantum-readiness headlines, thin float, no meaningful revenue — so a snap-back rally after a month of selling is not evidence of anything. |
| SDGR | Schrodinger, Inc. - Common Stock | Health Care | Health Information Services | 12.05% | 32.18% | 83.07% | 1.739e+09 | 3.1213 | 97.9 | — | 40 | 0.00% | Upward channel (100%), Uptrend | Computational drug-discovery platform at a new 52-week high. Partnership/milestone economics make this a royalty-like model on other people's molecules; the risk is that platform deals are lumpy and the market cap already discounts several. |
| TEM | Tempus AI, Inc. - Class A Common Stock | Health Care | Health Information Services | 10.67% | 32.15% | 35.32% | 1.242e+10 | 1.3041 | 36.8 | — | 46 | -33.32% | Uptrend | The market's favorite diagnostic-data franchise — sequencing plus clinical AI. Gains reflect demand for the companies monetizing compute output rather than building the hardware. Elevated multiple means it trades on sentiment toward AI-health budgets. |
| REF | Reformation Inc. | Consumer Discretionary | Apparel Retail | 9.58% | 2.25% | — | 9.393e+08 | 1.0534 | — | — | 4 | -5.58% | — | Recently listed apparel brand, and it just reported (very short days-since-earnings), so this is a post-print reaction with thin trading history. Small float stories like this can gap on low volume. |
| FPS | Forgent Power Solutions, Inc. | Industrials | Electrical Equipment & Parts | 9.50% | -20.93% | -9.26% | 9.547e+09 | 3.8668 | 32.3 | — | 0 | -51.45% | — | Power-distribution equipment for data centers — a pure AI-infrastructure capex play that has been caught in the violent de-rating of electrical equipment names. The bounce is a relief move inside a falling trend, not a trend change. |
| CAI | Caris Life Sciences, Inc. | Health Care | Biotechnology | 9.40% | 30.73% | 49.61% | 8.056e+09 | 1.9032 | 89.1 | 2.97 | 200 | -15.33% | Uptrend | Molecular diagnostics with a very long gap since its last report — this is momentum and sector sympathy with the life-science tools complex, not new information. Profitable on an IFRS basis with strong top-line growth, but extended after a month of gains. |
| QRVO | Qorvo, Inc. | Information Technology | Semiconductors | 9.34% | 20.33% | 50.76% | 1.042e+10 | 1.8478 | 90.9 | 27.39 | 48 | 0.00% | Uptrend | Second analog/RF name at a new high on the same dynamic as Skyworks — price increases, handset restocking, and expectations of industry consolidation. The two names frequently trade as a pair, and today they did. |
| RVTY | Revvity, Inc. | Health Care | Diagnostics & Research | 9.11% | 19.98% | 62.34% | 1.564e+10 | 2.3168 | 76.4 | 67.4 | 42 | 0.00% | Upward channel (100%), Uptrend | Life-science instruments and diagnostics — one of the few health-care sub-sectors with visible order books. Trades on its upward channel with improving pharma capex; the swing factor is China/ academic funding. |
| RIG | Transocean Ltd (Switzerland) | Energy | Oil & Gas Drilling | 8.99% | 3.12% | -4.19% | 6.634e+09 | 1.6103 | 15.9 | — | 40 | -21.64% | — | Offshore driller benefiting from crude near $85 and a structural shortage of deepwater rigs. Day rates are the earnings driver; balance-sheet leverage makes the equity a high-beta oil call — hence it needs oil to keep cooperating. |
| TENB | Tenable Holdings, Inc. | Information Technology | Software - Infrastructure | 8.58% | -0.63% | 87.73% | 4.195e+09 | 1.7528 | 91.7 | — | 47 | -10.69% | Uptrend | Exposure-management software. Interest here comes from cyber budget resilience and a durable subscription base; it has been re-rated faster than peers, so the multiple now embeds continued execution. |
| VAL | Valaris Limited | Energy | Oil & Gas Drilling | 8.56% | 3.05% | -3.62% | 6.126e+09 | 1.8622 | 28.8 | 6.65 | 40 | -22.21% | — | Second offshore driller, same commodity tailwind — the two names moving together tells you this is an oil-price trade rather than a company-specific catalyst. |
| KRMN | Karman Holdings Inc. | Industrials | Aerospace & Defense | 7.86% | -39.57% | -64.00% | 4.966e+09 | 1.3386 | 19.6 | 138.78 | 39 | -67.50% | Downtrend | Defense components name in a persistent downtrend with a punishing month. Aerospace & defense components have been among the weakest themes; the bounce is counter-trend and the valuation is still rich relative to current margins. |
| ADPT | Adaptive Biotechnologies Corporation - Common Stock | Health Care | Diagnostics & Research | 7.67% | 7.84% | 114.30% | 4.258e+09 | 1.5326 | 97.7 | — | 47 | 0.00% | Uptrend | Diagnostics/immuno-sequencing franchise benefiting from MRD-testing adoption and reimbursement wins. Still not consistently profitable, so it is sensitive to any shift in payer or clinical-trial sentiment. |
| SCTX | Scribe Therapeutics Inc. | Health Care | Biotechnology | 7.61% | 52.73% | — | 5.994e+08 | 0.7452 | — | — | 12 | -15.01% | — | Early-stage gene-editing company with a very small revenue base — moves are driven by pipeline news and financing risk rather than earnings. The strong one-month run means expectations have already reset higher. |
| MRCY | Mercury Systems Inc | Industrials | Aerospace & Defense | 7.38% | -21.70% | 1.17% | 5.232e+09 | 1.4194 | 86.5 | — | 27 | -31.06% | — | Defense electronics recovering after a sharp de-rating; the sector's aircraft-component complex is the weakest part of the market this month. Program delays and fixed-price contracts remain the core risk. |
| CVI | CVR Energy Inc. | Energy | Oil & Gas Refining & Marketing | 7.28% | 47.96% | 86.02% | 4.992e+09 | 0.9779 | 35.9 | 75.61 | 47 | 0.00% | Uptrend | Refiner with a nitrogen-fertilizer arm — the integrated margin story is doing the work here: strong crack spreads on high crude plus fertilizer pricing. Overbought on momentum and carrying the highest structural volatility score in the list. |
| QLYS | Qualys, Inc. | Information Technology | Software - Infrastructure | 7.21% | -0.37% | 95.15% | 6.413e+09 | 1.5357 | 98.4 | 32.13 | 41 | -5.37% | Uptrend | Vulnerability-management software, hurt recently by the broader security-software derating but supported by net cash and aggressive buybacks. Value-style cash returns in a growth sector is what draws buyers on down days. |
| WAY | Waystar Holding Corp. | Health Care | Health Information Services | 7.11% | 7.63% | 8.37% | 5.114e+09 | 2.0791 | 64.2 | 38.1 | 47 | -32.69% | Uptrend | Health-care payments/revenue-cycle software — a hospital and payer IT duopoly with high recurring revenue. Sector sympathy, but the leverage from its buyout history makes it rate-sensitive. |
| TBN | Tamboran Resources Corporation Common stock | Energy | Oil & Gas E&P | 6.95% | 9.16% | 35.20% | 1.401e+09 | 1.1297 | 8.7 | — | 124 | -19.62% | Sideways channel (100%), Uptrend | Small-cap Australian gas producer with a US listing; the move tracks gas prices and project-update flow rather than sector rotation. Thin liquidity and a short-dated catalyst calendar. |
| ILMN | Illumina, Inc. | Health Care | Diagnostics & Research | 6.76% | 16.45% | 86.36% | 3.357e+10 | 1.6025 | 92.3 | 41.39 | 46 | -2.37% | Upward channel (37%), Uptrend | Genomics tools bellwether at a new high — the read-through is that sequencer utilization and clinical volumes are improving, which lifts the whole life-science tools group. A cleaner way to own the diagnostics recovery than pre-profit peers. |
| EOSE | Eos Energy Enterprises, Inc. - Common Stock | Industrials | Electrical Equipment & Parts | 6.54% | 1.24% | -26.80% | 1.472e+09 | 0.9672 | 0.1 | — | 41 | -78.79% | Downtrend | Zinc-based utility-scale storage developer, still pre-profit with a manufacturing ramp to fund. The recent multi-quarter drawdown in industrial energy storage gives any financing or order headline outsized effect. |
Top Losers — September 15, 2026
| Symbol | Security Name | Sector | Industry | 1D Return | 1M Return | 6M Return | Market Cap | Relative Volume | Momentum Potential | P/E (TTM) | Days Since Earnings | % From 52W High | Technical Setup | Comments |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| SWMR | Swarmer, Inc | Information Technology | Software - Infrastructure | -28.36% | -44.62% | — | 3.672e+08 | 12.1623 | — | — | 32 | -70.66% | — | Drone-swarmer defense startup, tiny and freshly listed — extreme relative volume on a down day indicates a liquidity event or lockup/placement overhang rather than a fundamental change. Downside gaps in this cohort tend to persist. |
| ENVA | Enova International, Inc. | Financials | Credit Services | -23.43% | -34.60% | 29.48% | 4.323e+09 | 4.9662 | 96.8 | 12.89 | 53 | -34.60% | Uptrend | Consumer and small-business lender rolled over hard. Credit-sensitive lenders de-rate fast when the market starts pricing borrower stress or a slower origination backdrop — despite the sector still showing long-term uptrend structure. This is the classic 'good company, credit-cycle question' setup. |
| ALHC | Alignment Healthcare, Inc. | Health Care | Healthcare Plans | -19.86% | -25.72% | -38.96% | 2.151e+09 | 5.192 | 19.7 | 54.58 | 46 | -57.78% | Downtrend | Medicare Advantage insurer punished on cost-trend and risk-coding concerns. MA margins are driven by utilization and rate notices; when one plan disappoints, the market extrapolates across the group, so watch peer read-through more than the individual print. |
| SION | Sionna Therapeutics, Inc. - Common Stock | Health Care | Biotechnology | -16.71% | 6.50% | -81.49% | 3.106e+08 | 1.2062 | 6 | — | 40 | -86.52% | Downtrend | Early-stage biotech with a collapsed six-month chart — the decline reflects clinical/regulatory disappointment and, likely, financing risk. Micro-cap cash-burners at these prices are options, not investments. |
| KRUS | Kura Sushi USA, Inc. | Consumer Discretionary | Restaurants | -14.01% | -33.01% | -39.86% | 4.957e+08 | 1.9436 | 5.4 | — | 69 | -57.26% | Downtrend | Revolving-sushi chain exposed to consumer discretionary spending and restaurant traffic. Small-cap restaurant brands are being de-rated across the board as labor and food costs meet softer traffic. |
| EYPT | EyePoint, Inc. - Common Stock | Health Care | Biotechnology | -13.88% | -75.19% | -72.79% | 3.069e+08 | 1.0788 | 0.3 | — | 41 | -80.58% | Downtrend | Retinal-disease biotech down sharply over the month — a program-level setback has removed conviction. With a cash runway question attached, the equity remains highly headline-sensitive. |
| DMRA | Damora Therapeutics, Inc. - Common Stock | Health Care | Biotechnology | -12.82% | -20.26% | -0.92% | 1.528e+09 | 2.873 | 87.9 | 6.22 | 35 | -27.50% | — | Clinical-stage therapeutics name with a volatile listing history. Moves at this market cap are positioning and news, and the low intraday liquidity means wide spreads. |
| FWDI | Forward Industries, Inc. | Consumer Discretionary | Footwear & Accessories | -12.52% | 42.72% | 16.92% | 4.49e+08 | 1.6099 | 17.4 | — | 33 | -84.41% | Uptrend | Apparel/accessories business that has rallied strongly over the month on a corporate-transaction narrative, so today's pullback looks like profit-taking on a crowded story rather than a change in the thesis. |
| ARWR | Arrowhead Pharmaceuticals, Inc. - Common Stock | Health Care | Biotechnology | -12.40% | -18.43% | 23.18% | 9.982e+09 | 2.101 | 93.1 | — | 41 | -21.12% | Uptrend | RNA-interference biotech with a large pipeline and large cash needs. Idiosyncratic clinical readouts drive everything; the long-term chart is still up massively, which is why volatility stays high on both sides. |
| WING | Wingstop Inc. | Consumer Discretionary | Restaurants | -12.09% | -20.04% | -49.11% | 2.747e+09 | 2.3267 | 12 | 23.84 | 48 | -64.58% | Downtrend | Fast-casual wing chain facing the sector-wide traffic slowdown, plus company-specific concerns about growth-unit economics and franchisee health. The multiple compression is being driven by decelerating same-store sales, and the downtrend is intact. |
| MAMA | Mama's Creations, Inc. | Consumer Staples | Packaged Foods | -11.69% | -23.83% | -21.79% | 6.195e+08 | 3.0241 | 76.7 | 87.6 | 11 | -36.37% | — | Small-cap prepared-foods maker with a recent report — this is an earnings-reaction move. Input costs and slotting/retail distribution economics are the swing factors for packaged-food names at this scale. |
| CRCL | Circle Internet Group, Inc. | Financials | Capital Markets | -11.41% | 20.53% | -31.42% | 2.352e+10 | 1.6047 | 50.7 | 17.29 | 41 | -42.65% | — | Stablecoin issuer hit directly by the failure of crypto market-structure legislation — the company's economics depend on regulatory clarity and reserve yield. Its stock price moves with policy headlines, not with token prices, which is the core mismatch for investors. |
| RML | Resolution Minerals Ltd - American Depositary Shares | — | — | -10.72% | — | — | 2.598e+10 | 0.1847 | — | — | — | -42.59% | — | Micro-cap foreign mining ADR trading with almost no liquidity and no coverage — treat the print here as noise, not a signal about anything. |
| CBRL | Cracker Barrel Old Country Stor | Consumer Discretionary | Restaurants | -10.65% | -22.06% | 65.55% | 1.009e+09 | 1.508 | 33.8 | 39.26 | 97 | -23.53% | Uptrend | Restaurant chain in a headline-driven turnaround and brand-restructuring debate; sentiment is doing more work than the P&L. Trading after a long gap since earnings means the move is positioning-driven. |
| BOOT | Boot Barn Holdings, Inc. | Consumer Discretionary | Apparel Retail | -10.13% | -21.40% | -18.06% | 3.888e+09 | 2.7924 | 51.4 | 16.25 | 47 | -38.28% | Sideways channel (0%), Downtrend, Break-below | Western-wear retailer with a technical break below a sideways range. Consumer discretionary specialty retail is the weakest corner of the tape right now, and tariff-related cost commentary on the next print is a live risk. |
| COIN | Coinbase Global, Inc. | Financials | Financial Data & Stock Exchanges | -10.10% | 15.92% | -15.35% | 4.541e+10 | 2.1507 | 57.9 | 38.68 | 46 | -55.56% | — | Crypto exchange sold off with the broader digital-asset complex after the legislative setback, despite tokens themselves being the month's best performers. Business model remains high-beta to trading volumes and regulatory outcomes. |
| BLMN | Bloomin' Brands, Inc. | Consumer Discretionary | Restaurants | -10.10% | -24.08% | 42.78% | 6.858e+08 | 1.5271 | 55.7 | 25.03 | 41 | -32.41% | Uptrend | Casual-dining operator with heavy debt and a value-traffic problem; casual dining is being squeezed from both ends by fast-casual and grocery. Note its structural volatility score sits at the top of the list, so balance-sheet risk is real. |
| ARHS | Arhaus, Inc. | Consumer Discretionary | Specialty Retail | -10.04% | -25.54% | 8.57% | 1.034e+09 | 0.7754 | 34.3 | 14.61 | 40 | -38.46% | Upward channel (0%) | Furniture retailer with an upward channel failing at the low end. Big-ticket home goods depend on housing turnover and consumer financing conditions, both of which remain headwinds. |
| BOBS | Bob's Discount Furniture, Inc. | Consumer Discretionary | Specialty Retail | -9.85% | -23.04% | -7.50% | 1.903e+09 | 0.9359 | 68.5 | 14.27 | 40 | -35.38% | — | Recently listed furniture retailer — very little public trading history, so the decline is partly IPO-holder supply rather than a full fundamental reassessment. Housing-linked big-ticket demand is the structural issue. |
| ASMB | Assembly Biosciences, Inc. - Common Stock | Health Care | Biotechnology | -9.84% | -20.76% | -9.15% | 5.316e+08 | 2.2407 | 56.4 | — | 32 | -32.18% | — | Micro-cap antiviral biotech; today's drop looks like a clinical/partnership disappointment with follow-through selling in an already weak long-term chart. Financing risk is the dominant consideration. |
| AXON | Axon Enterprise, Inc. | Industrials | Aerospace & Defense | -9.81% | -27.86% | -9.71% | 3.591e+10 | 2.8603 | 36.3 | 182.68 | 40 | -43.15% | — | The most notable large-cap casualty: a high-multiple law-enforcement technology franchise with a persistent downtrend. This is the same long-duration growth de-rating hitting quality industrials — the market is no longer paying premium multiples for backlog, no matter how recurring. |
| DSGN | Design Therapeutics, Inc. - Common Stock | Health Care | Biotechnology | -9.58% | -17.57% | 11.24% | 7.651e+08 | 1.8277 | 51.3 | — | 43 | -23.31% | Upward channel (2%), Uptrend | Gene-targeting biotech in an upward channel that failed today. Pre-revenue, so the chart is the story until the next data readout. |
| ASND | Ascendis Pharma A/S | Health Care | Biotechnology | -9.49% | -3.51% | 3.79% | 1.577e+10 | 4.3081 | 69.1 | 18.5 | 33 | -13.50% | — | Rare-disease endocrinology name with commercial products, not just a pipeline. The decline is broad biotech risk-off rather than a company-specific event, but the name is heavily reliant on a handful of franchise drugs. |
| EYE | National Vision Holdings, Inc. | Consumer Discretionary | Specialty Retail | -9.48% | -17.88% | -41.21% | 1.253e+09 | 1.21 | 11.6 | 25.56 | 34 | -46.20% | Downtrend | Optical retail chain; specialty retail is the weakest sub-sector in the market this month, and vision care is exposed to discretionary spending and managed-care reimbursement. Structurally low-margin, so small traffic declines swing earnings hard. |
| GEMI | Gemini Space Station, Inc. - Class A Common Stock | Financials | Capital Markets | -9.46% | 11.10% | -39.68% | 5.646e+08 | 1.0457 | 6.5 | — | 32 | -86.61% | Downtrend | Crypto exchange listing down with the digital-asset group on the same regulatory catalyst as peers. Newly public, thinly traded, and highly policy-dependent. |
Takeaway
Reading the tape
Today's movers are a single-name market, not a sector call. Roughly two stocks fell for every one that rose, only about a third of the market still holds its 50-day average, and 61 names broke support versus 11 that broke resistance — yet both ends of the leaderboard are full of idiosyncratic gaps rather than a clean rotation.
Gainers: the market paid for output, not tools
Health care dominates the upside — diagnostics and life-science tools (Illumina, Revvity, Adaptive, Caris, Tempus, Schrodinger) plus a CRO (Fortrea) — alongside a pair of analog/RF semiconductor names (Skyworks, Qorvo) that hit new highs. That split matters: the winners are companies monetizing compute and clinical demand, while the day's weakest themes remain the builders of hardware — semicap equipment, memory, photonics and Lidar. Energy-linked names also showed up (offshore drillers, a refiner, a gas E&P), consistent with crude near $85 and Energy as the only sector still in a clear monthly uptrend.
Losers: consumer discretionary and anything policy-dependent
Restaurants, specialty retail and apparel fill the bottom half — Kura Sushi, Wingstop, Bloomin' Brands, Cracker Barrel, Boot Barn, Arhaus, Bob's Discount, National Vision. Discretionary is the weakest sector in the market on both a monthly return and breadth basis, and today amplified it. The other cluster is policy-sensitive finance: Circle and Coinbase both sold off after digital-asset market-structure legislation failed its Senate vote, a reminder that regulation rather than earnings sets the price of that complex. Health-care biotech also appears on the downside in a broad pre-revenue de-risking, and Axon — a premium-multiple quality industrial — is the clearest example of the market refusing to pay up for long-duration growth.
How to use this list
Gaps of this size usually mean news, not opportunity. Check the catalyst before acting; where there is no catalyst, treat the move as positioning. The highest-quality signal in the screen is a cluster: diagnostic/life-science strength is a real demand read-through, and analog semis hitting new highs while the AI hardware complex unwinds is a genuine rotation worth tracking over the coming weeks.
