Largest US Stock Movers — October 9, 2026
Query: top movers today · data as of 2026-10-09
Rebuilt the daily movers screen from the 2026-10-09 session: a 25-name Top Gainers table led by clinical-stage biotech/health care plus a tower-REIT bid, and a 25-name Top Losers table dominated by the US wireless/telecom complex re-rated on spectrum news, with rate-sensitive REITs, materials and cyclicals also weak. Both tables are ranked purely by 1D return and include sector, industry, 1M/6M returns, market cap, relative volume, momentum potential, P/E, days since earnings and % from 52-week high, with fresh per-row commentary and a new market narrative.
Single-session extremes from the most recent trading day (October 9, 2026). Gainers are led by clinical-stage biotech and health care names plus a tower-REIT bid, while the losers list is dominated by US wireless carriers re-rated on spectrum news, with REITs, materials and cyclicals along for the ride.
Top Gainers — October 9, 2026
| Symbol | Security Name | Sector | Industry | 1D Return | 1M Return | 6M Return | Market Cap | Relative Volume | Momentum Potential | P/E (TTM) | Days Since Last Earnings | % From 52-Week High | Comments |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| KLRA | Kailera Therapeutics, Inc. - Common stock | Health Care | Biotechnology | 16.10% | -22.13% | — | 1.505e+09 | 2.3703 | — | — | 57 | -55.35% | Recent IPO with thin trading history; the rebound follows a sharp post-listing derating and is likely positioning flow rather than a fundamental change. Expect wider swings than the biotech cohort until lockups clear. |
| FSLY | Fastly, Inc. | Information Technology | Software - Application | 15.86% | 29.02% | 27.00% | 4.667e+09 | 2.2846 | 82.7 | — | 64 | -12.54% | Edge-compute/CDN turnaround story regaining credibility as security and network demand inflects. Still unprofitable, so the re-rating hinges on sustained large-deal momentum rather than multiple expansion. |
| NVAX | Novavax, Inc. - Common Stock | Health Care | Biotechnology | 15.80% | 37.10% | 57.02% | 2.103e+09 | 3.3997 | 88.9 | 4.94 | 64 | 0.00% | Vaccine maker with a history of binary clinical headlines; moves of this size typically track trial data, regulatory read-throughs or patent/legal developments. Balance-sheet survival narrative remains the key swing factor. |
| CCI | Crown Castle Inc. | Real Estate | REIT - Specialty | 15.60% | 9.38% | -5.27% | 3.48e+10 | 3.7831 | 39.8 | 32.51 | 78 | -19.45% | Tower REITs were re-priced higher as the wireless complex repriced spectrum, shifting the demand debate toward whether terrestrial infrastructure is more or less durable. Also a rate-sensitive dividend name, so lower yields amplify the move. |
| DNA | Ginkgo Bioworks Holdings, Inc. Class A Common Stock | Health Care | Biotechnology | 14.64% | 91.74% | 101.55% | 8.754e+08 | 2.3495 | 59.1 | — | 64 | -17.88% | Speculative synthetic-biology platform with heavy cash burn; gains like this are usually liquidity-driven moves in a high-short-interest name rather than earnings-based. |
| MRNA | Moderna, Inc. - Common Stock | Health Care | Biotechnology | 14.21% | 64.69% | 341.52% | 8.983e+10 | 1.5096 | 86.9 | — | 70 | 0.00% | Recovering sharply from a deep drawdown as the biotech funding window reopens and pipeline catalysts re-enter the story. High-volatility, headline-sensitive — sizing matters more than direction. |
| ABSI | Absci Corporation - Common Stock | Health Care | Biotechnology | 13.65% | 23.30% | 240.94% | 1.744e+09 | 1.2524 | 68.3 | — | 58 | -12.56% | AI-driven drug discovery name riding the same risk-on biotech bid; precommercial economics mean the stock trades on partnerships and platform validation, not revenue. |
| PICS | PicS N.V. | Information Technology | Software - Infrastructure | 13.52% | 29.40% | 14.00% | 1.762e+09 | 1.9895 | — | — | 45 | -28.42% | Small-cap infrastructure software with thin coverage; move looks like liquidity-sensitive repricing, so verify any news before extrapolating. |
| HUM | Humana Inc. | Health Care | Healthcare Plans | 11.56% | 7.77% | 125.29% | 5.186e+10 | 3.8415 | 76 | 40.82 | 72 | 0.00% | Medicare Advantage economics have been improving on star-rating and reimbursement tailwinds, and managed-care is being re-rated as policy risk recedes. Guidance risk into its upcoming report is the main offset. |
| PRME | Prime Medicine, Inc. - Common Stock | Health Care | Biotechnology | 11.45% | 19.10% | 16.33% | 7.237e+08 | 2.3804 | 10.9 | — | 64 | -37.36% | Gene-editing platform still early in clinical development; sharp moves here reflect financing and data expectations, and dilution risk remains a structural overhang. |
| CCCC | C4 Therapeutics, Inc. - Common Stock | Health Care | Biotechnology | 10.88% | -7.06% | 24.65% | 3.888e+08 | 1.0831 | — | — | 59 | -32.33% | Small-cap targeted-degradation biotech bouncing off a base — speculative money rotating into high-beta, low-float research names. |
| AUGO | Aura Minerals Inc. | Materials | Gold | 10.63% | 6.10% | 4.81% | 7.651e+09 | 1.3013 | — | — | 64 | -16.38% | Gold producer with exposure to Brazil and Latin America; the bid is partly company-specific (production/asset news) and partly a safe-haven rotation that the broader miners group has not shared. |
| ATEX | Anterix Inc. - Common Stock | Communication Services | Telecom Services | 10.58% | 2.10% | 135.53% | 1.658e+09 | 1.5593 | 99.2 | 24.22 | 58 | -21.88% | Spectrum-holding utility-like name that benefits directly from the same scarcity narrative that hurt the carriers. Its value case rests on monetizing 900 MHz spectrum, so any deal talk is a live catalyst. |
| RXRX | Recursion Pharmaceuticals, Inc. - Class A Common Stock | Health Care | Biotechnology | 10.38% | 37.97% | 32.93% | 2.338e+09 | 1.7231 | 18.1 | — | 65 | -35.79% | AI-plus-biotech platform with retail attention; it trades as a high-beta expression of both the biotech funding thaw and the machine-learning theme. |
| HIMS | Hims & Hers Health, Inc. | Health Care | Drug Manufacturers - Specialty & Generic | 10.19% | 12.68% | 59.14% | 7.214e+09 | 1.314 | 74.9 | 60.63 | 59 | -50.73% | Direct-to-consumer health platform where competitive and regulatory headlines around compounded GLP-1s have been the dominant driver. Growth is real but the multiple depends on regulatory durability. |
| SCTX | Scribe Therapeutics Inc. | Health Care | Biotechnology | 10.09% | -28.16% | — | 4.008e+08 | 1.1028 | — | — | 36 | -43.17% | Gene-editing startup rebounding from a steep drawdown; moves of this magnitude in a sub-$1B name usually reflect low-float dynamics more than revised fundamentals. |
| IOVA | Iovance Biotherapeutics, Inc. - Common Stock | Health Care | Biotechnology | 9.84% | 79.61% | 295.14% | 6.622e+09 | 0.9706 | 68.5 | — | 64 | -1.35% | Cell-therapy commercial-stage name with a strong recent run; pipeline expansion and reimbursement traction are what keep the momentum trade alive. |
| PCVX | Vaxcyte, Inc. - Common Stock | Health Care | Biotechnology | 9.79% | 21.19% | 17.25% | 1.062e+10 | 2.4125 | 64.1 | — | 64 | -3.31% | Pneumococcal vaccine developer anticipating key trial readouts — event-driven biotech where the binary skew makes it a candidate for outsized swings either way. |
| SEZL | Sezzle Inc. | Financials | Credit Services | 9.74% | 8.64% | 115.46% | 4.332e+09 | 1.1117 | 97.9 | 28.21 | 63 | -31.77% | Consumer credit/BNPL platform with very high momentum and volatility scores; results hinge on credit quality through the consumer cycle, making it a levered bet on spending resilience. |
| HPK | HighPeak Energy, Inc. - Common Stock | Energy | Oil & Gas E&P | 9.39% | 11.31% | 50.63% | 1.208e+09 | 1.4968 | 60 | 68.21 | 59 | 0.00% | Small E&P benefiting from firm crude and favorable refining/E&P spreads; low float and high beta amplify commodity-driven moves. |
| AMT | American Tower Corporation (REI | Real Estate | REIT - Specialty | 9.30% | 6.49% | 4.76% | 8.492e+10 | 3.0822 | 41.7 | 29.39 | 73 | -6.12% | The other major tower REIT caught the same wireless-spectrum re-rating as its peer — the market read the transaction as a validation of tower demand rather than a threat. |
| SECZ | Securitize Corp. | Information Technology | Software - Application | 9.16% | 71.89% | — | 2.256e+09 | 1.8777 | — | — | 57 | -16.90% | Tokenization/blockchain-infrastructure exposure with a recent listing; the move fits a broader crypto-adjacent risk-on bid rather than company fundamentals. |
| PLNT | Planet Fitness, Inc. | Consumer Discretionary | Leisure | 8.97% | -4.00% | -31.85% | 3.639e+09 | 1.3638 | 9.3 | 16.32 | 64 | -57.15% | Franchise-heavy gym operator bouncing from deeply oversold levels; the structural debate is membership growth versus new-unit economics, and the report cadence makes it headline-driven. |
| BRUN | Boost Run Inc. | Information Technology | Software - Infrastructure | 8.93% | -19.93% | 15.82% | 1.048e+09 | 1.2304 | 24.9 | — | 51 | -66.38% | Micro-cap infrastructure software; likely a low-float squeeze after a long decline. Treat the move as liquidity, not signal. |
| DOCN | DigitalOcean Holdings, Inc. | Information Technology | Software - Infrastructure | 8.81% | 2.88% | 78.36% | 1.585e+10 | 0.6596 | 64.4 | 61.28 | 66 | -25.63% | Cloud developer platform that has become increasingly AI-inference-exposed; improving operating discipline underpins the re-rating, but competitive pressure from hyperscalers is the persistent risk. |
Top Losers — October 9, 2026
| Symbol | Security Name | Sector | Industry | 1D Return | 1M Return | 6M Return | Market Cap | Relative Volume | Momentum Potential | P/E (TTM) | Days Since Last Earnings | % From 52-Week High | Comments |

| GLIBK | Liberty Capital Corporation - Series C GCI Group Common Stock | Communication Services | Telecom Services | -15.01% | -22.01% | -44.34% | 8.001e+08 | 1.8 | 1.2 | — | — | -49.93% | Tracking-stock structure and thin liquidity make this one prone to outsized moves that may not reflect underlying asset values. |
| ALHC | Alignment Healthcare, Inc. | Health Care | Healthcare Plans | -13.38% | -40.87% | -64.71% | 1.565e+09 | 3.1666 | 17.4 | 39.71 | 70 | -69.28% | Medicare Advantage pure-play being sold hard while the larger MCOs rally — this is exactly the wrong-end-of-the-pool dynamic where the market rewards scale and reserves and punishes sub-scale risk. |
| TMUS | T-Mobile US, Inc. | Communication Services | Telecom Services | -13.27% | -16.13% | -23.23% | 1.594e+11 | 3.7948 | 11.2 | 15.54 | 78 | -35.43% | The carrier most exposed to the spectrum-deal narrative: the market is questioning whether satellite/direct-to-device capacity erodes the value of massive terrestrial capex. A genuine strategy re-rating, not just a sympathy move. |
| PKE | Park Aerospace Corp. | Industrials | Aerospace & Defense | -11.06% | -13.74% | -14.70% | 5.738e+08 | 3.4025 | 89 | 41.87 | 0 | -31.00% | Small aerospace composites supplier with heavy defense-program concentration; single-contract news or program timing can move the stock violently. |
| T | AT&T Inc. | Communication Services | Telecom Services | -10.82% | -13.19% | -15.05% | 1.52e+11 | 3.091 | 14.7 | 7.32 | 79 | -23.78% | Wireline-heavy carrier with a levered balance sheet and a fiber build to fund — the same capital-allocation anxiety hitting the whole wireless complex lands hardest on the highest-yielding incumbents. |
| CCOI | Cogent Communications Holdings, Inc. - Common Stock | Communication Services | Telecom Services | -10.67% | -6.05% | -57.82% | 4.374e+08 | 0.7219 | 1.4 | — | 64 | -81.06% | The most structurally impaired of the telecom complex: heavy leverage, enterprise/wholesale pressure, and a dividend the market doubts. Moves here are credit-sentiment-driven. |
| ASTS | AST SpaceMobile, Inc. - Class A Common Stock | Information Technology | Communication Equipment | -10.48% | -14.93% | -46.30% | 1.983e+10 | 4.3844 | 10.1 | — | 59 | -61.71% | Satellite-to-phone pure-play already in a downtrend — ironic loser of the satellite-bull case because the trade is being financed (valuation, dilution, timeline) rather than validated. |
| VZ | Verizon Communications Inc. | Communication Services | Telecom Services | -10.14% | -16.65% | -7.99% | 1.73e+11 | 4.1454 | 36.6 | 10.85 | 77 | -19.05% | Wireless incumbent with the strongest dividend identity; the de-rating reflects a market now questioning long-tail spectrum and tower economics rather than near-term earnings. |
| SHEN | Shenandoah Telecommunications Co - Common Stock | Communication Services | Telecom Services | -9.68% | -13.15% | -31.27% | 5.761e+08 | 1.4454 | 10.7 | — | 72 | -39.15% | Regional wireline with a rural fiber build and limited scale — funding and competitive concerns compound in a session that punished telecom broadly. |
| TIGO | Millicom International Cellular | Communication Services | Telecom Services | -9.63% | -16.93% | -2.69% | 1.333e+10 | 1.2931 | 58.5 | 19.87 | 64 | -23.80% | Latin American mobile operator that had been a strong momentum name; the pullback looks like de-risking of a crowded, high-volatility position in an otherwise strong trend. |
| IDR | Idaho Strategic Resources, Inc. | Materials | Gold | -9.58% | -22.23% | -35.79% | 3.765e+08 | 4.7111 | 72.8 | 16.29 | 57 | -54.82% | Junior gold miner that had run hard; the drawdown is the reverse of the safe-haven bid and a reminder that low-float miners trade on flows, not ounces. |
| AVNT | Avient Corporation | Materials | Specialty Chemicals | -7.78% | -8.82% | 0.31% | 3.466e+09 | 3.3241 | 55.9 | 20.43 | 64 | -18.45% | Specialty chemicals with broad industrial-end exposure; the move fits the market's continued refusal to pay for economic cyclicality. |
| SPRY | ARS Pharmaceuticals, Inc. - Common Stock | Health Care | Biotechnology | -7.24% | -16.40% | -47.45% | 4.207e+08 | 0.6722 | 4.5 | — | 56 | -67.61% | Commercial-stage allergy/severe-anaphylaxis player where launch execution and reimbursement are the swing factors; small-cap biotech risk is being repriced even as the group rallies. |
| AGNT | AGNT, Inc. | Real Estate | Real Estate Services | -7.23% | -0.80% | -35.71% | 6.217e+08 | 0.8384 | 4.9 | — | 66 | -68.47% | Nano-cap real-estate services name in a persistent downtrend; the move is likely liquidity and financing related rather than operating news. |
| UNIT | Uniti Group Inc. - Common Stock | Real Estate | REIT - Specialty | -7.16% | -30.40% | -36.62% | 2.163e+09 | 2.4625 | 23.1 | 1.41 | 71 | -46.12% | Levered fiber/REIT hybrid where the market is again focused on whether the capital structure can tolerate its buildout — highly sensitive to credit spreads and telecom sentiment. |
| BKD | Brookdale Senior Living Inc. | Health Care | Medical Care Facilities | -7.07% | -17.05% | -25.31% | 2.417e+09 | 3.719 | 3.3 | — | 59 | -39.65% | Senior-living operator that has been in a downtrend; labor costs and occupancy-driven margin recovery are what the market wants to see before re-engaging. |
| RSI | Rush Street Interactive, Inc. | Consumer Discretionary | Gambling | -6.99% | -28.30% | -10.38% | 4.616e+09 | 0.8985 | 43.2 | 60.97 | 71 | -45.25% | Online-gaming operator in a group that has been the worst-performing consumer theme — competitive customer-acquisition costs are the structural issue. |
| HPQ | HP Inc. | Information Technology | Computer Hardware | -6.91% | -7.73% | 69.03% | 2.723e+10 | 1.1031 | 48 | 11.19 | 43 | -14.88% | The pullback hit after a huge run tied to AI-PC and hardware enthusiasm, but core printing/PC demand remains mature — this is a valuation give-back, not a broken thesis. |
| LILAK | Liberty Latin America Ltd. | Communication Services | Telecom Services | -6.88% | -6.45% | 44.36% | 1.665e+09 | 1.2557 | 70.5 | — | 64 | -8.35% | Latin American cable/mobile operator; cable-leverage and currency concerns drag it even when the operating trend is intact. |
| GRRR | Gorilla Technology Group Inc. | Information Technology | Software - Infrastructure | -6.78% | -19.11% | 1.46% | 3.062e+08 | 2.4441 | 21 | — | 45 | -48.90% | Micro-cap AI story stock with a history of governance and disclosure concerns — volatility here is a feature, not a bug, and position sizing should reflect that. |
| PARR | Par Pacific Holdings, Inc. Comm | Energy | Oil & Gas Refining & Marketing | -6.57% | -2.03% | 30.46% | 4.103e+09 | 1.0232 | 86.8 | 4.81 | 65 | -6.57% | Small refiner with strong momentum that sold off despite firm crude; refining margins and Pacific-basin spreads drive earnings, and the group remains a funding source on risk-off days. |
| FMC | FMC Corporation | Materials | Agricultural Inputs | -6.39% | -30.26% | -51.39% | 1.299e+09 | 1.3593 | 2.1 | — | 71 | -72.74% | Agricultural chemicals name in a deep downtrend as generic competition resets pricing; the dividend is now a question rather than a support. |
| FRMI | Fermi Inc. | Real Estate | REIT - Specialty | -6.28% | -36.36% | -29.57% | 2.2e+09 | 0.7672 | 24.5 | — | — | -88.57% | Newly public REIT with essentially no operating history and no fundamentals coverage — price discovery is chaotic and the signal quality is low. |

Summary
One session, two very different kinds of volatility
Health Care went vertical at the top of the board. Seven of the twenty-five largest gainers are clinical- or platform-stage biotechs (Kailera, Novavax, Ginkgo, Moderna, Absci, Prime Medicine, C4, Recursion, Scribe, Iovance, Vaxcyte), and when that many small- and mid-cap life-science names move double digits together, it is usually money being repositioned into the sector rather than a single study result. The broader setup supports that read: biotech funding has been thawing, genomics ETFs are among the month's best performers, and pharma M&A is re-accelerating — a combination that rewards the highest-beta, most event-driven part of the market first.
The ladder was climbed, not just the elevator. Humana and Sezzle show the two other engines of this tape: managed-care economics are improving on star-rating and reimbursement tailwinds, while consumer credit keeps working as long as spending holds. Software and infrastructure names (Fastly, DigitalOcean, Securitize, PicS) participated on the same AI-adoption logic the market has been rewarding for weeks.
The telecom complex was repriced in an afternoon
The losers table is dominated by one event. Roughly half of the names are US and international carriers — T-Mobile, AT&T, Verizon, Cogent, Shenandoah, Millicom, Liberty Latin America — alongside the confirmation trade of the same news: Crown Castle and American Tower both appear in the gainers list. When a single capital-allocation decision can reprice a decades-old infrastructure moat, the market does not discriminate within the group; it de-risks the whole complex and re-directs capital toward the assets it now considers more durable. Note that AST SpaceMobile, the purest satellite-expression of the thesis, fell — a useful reminder that a narrative and a trade are not the same thing once valuation and financing enter the picture.
What is actually being punished
Look past the telecom block and the rest of the downside list is the same trade the market has been refusing to fund all month: rate- and credit-sensitive assets. Mortgage and specialty REITs (Uniti, Fermi, KKR Real Estate Finance), small engineering & construction, specialty chemicals, agricultural inputs and senior living all sit at or near lows with deeply negative monthly returns. This is not company-level bad news; it is the market declining to pay for economic cyclicality and balance-sheet leverage while the 10-year sits near 4.6% and the dollar stays firm.
How to use this screen
Single-day extremes are a discovery tool, not a ranking of quality — the largest movers are disproportionately micro-caps, recent IPOs and low-float names where a handful of orders can print a double-digit change. Cross-reference the 1M and 6M columns and relative volume before treating any name as a trend: a cluster of health-care names with rising monthly returns is a sector signal, whereas an isolated +10% in a thinly traded micro-cap is usually noise. Finally, earnings season is opening now — several names here report within days, so headline risk is elevated on both sides of the board.
