Overall Economic Summary

The Fed delivered its first rate hike since 2023 yesterday, lifting the target range 25bp to 3.75%–4.00% under new Chair Kevin Warsh — and the accompanying dot plot penciled in at least one more hike, a hawkish surprise that hit equities into Wednesday’s close and sent the 10-year yield pressing toward 5%. Warsh, who a year ago was criticizing the Fed for keeping rates too high, is now defying President Trump’s push for cuts as war-related supply shocks and tariff-driven inflation keep price pressures elevated. Futures are bouncing this morning as traders digest the hike alongside a still-resilient earnings and AI-capex backdrop, but the move higher looks more like relief than conviction.

Sector-wise, the AI infrastructure buildout remains the dominant equity narrative: all 11 S&P sectors are green pre-market, led by Industrials, Materials and Technology. A wave of bitcoin-miner-to-AI-datacenter pivots is producing today’s most extreme gappers — Core Scientific’s $14B+, 15-year AMD colocation partnership, Cipher Digital’s data-center power-supply update (Bernstein reiterated Buy Sept 1), and TeraWulf’s ~$19B, 20-year Anthropic lease are all driving outsized pre-market volume in names most day traders watch closely. Separately, Nvidia’s Jensen Huang and OpenAI’s Sarah Friar are meeting King Charles III in Scotland today alongside Google DeepMind’s Demis Hassabis, underscoring how central the AI buildout has become to markets and policy alike.

Key risks into the session: trade tensions are escalating again (Trump is threatening EU tariffs tied to a proposed EU–Canada associate-membership deal, and Congress just passed a bill enabling tariffs on buyers of Russian oil), the 10-year yield is flirting with the psychologically important 5% level as the market reprices a more hawkish Fed path, and tomorrow (Friday, Sept 18) is quadruple-witching — expect elevated volume and potential pinning/volatility into Friday’s close. VIX cooling nearly 10% off yesterday’s spike suggests the immediate fear flare-up is unwinding, even as the CNN Fear & Greed Index still reads “Fear” at 28.

Market Sentiment

Regime call: BULLISH. S&P 500 futures are +0.82% (ES1!, Bloomberg’s 7:26 AM ET snapshot had them +0.9% at 7,688), Nasdaq 100 futures +1.09%, and Dow futures +0.77% this morning — comfortably above the +0.25% threshold that triggers a long-only bias. Filtering long setups first today. Breadth confirms the call: the Russell 2000 is +0.89% and every S&P sector is positive pre-market. Watch the 10Y yield (4.97%, pressing toward 5%) and tomorrow’s quad-witching expiration as the two wildcards that could flip intraday tone.

Top 5 Movers

NBISNebius Group N.V.
$209.37 +9.44%
Technology services (AI cloud infra) · Pre-mkt Vol: 586K (avg 13.9M, 2.82x rel.) · ATR: $17.05 · Float: large-cap, $56.9B mkt cap

CATALYST: No single confirmed headline this morning, but Nebius — the vertically-integrated AI cloud/GPU infrastructure provider spun out of Yandex — is extending its recent AI-capex-driven strength as the sector’s highest-liquidity pre-market gapper.

WHY IT’S MOVING: Broad AI infrastructure enthusiasm (Yahoo Morning Brief: “AI profit growth is showing up everywhere”) plus today’s bullish regime and heaviest pre-market volume of the entire scan (586K shares) are pulling institutional flow into the largest, most liquid AI-infra name.

KEY DAILY PRICE LEVELS: VWAP anchor ~$209 (~est.). Expected opening range $205–$213 (~est.). 20/50-day MAs trending up, price extended above both (~est.). ATR(14): $17.05 — a full-ATR move today would be an outsized event. Bias: long, buy pullbacks to VWAP.

SUPPORT & RESISTANCE: Support: $200.85 (0.5 ATR), $192.32 (1 ATR, prior base). Resistance: $217.90 (0.5 ATR), $226.42 (1 ATR, psychological/round-number zone).

CORZCore Scientific, Inc.
$16.88 +6.21%
Technology services (AI datacenter) · Pre-mkt Vol: 197K (avg 12.3M, 6.11x rel.) · ATR: $1.19 · Float: $5.4B mkt cap

CATALYST: Core Scientific announced a landmark 15-year, $14B+ colocation partnership with AMD for 530 MW of data-center capacity, expanding to 2.5 GW — a hard, contracted-revenue catalyst as the company continues its pivot from bitcoin mining to AI colocation.

WHY IT’S MOVING: Relative volume of 6.11x (highest of today’s scan) confirms institutional participation; Q2 colocation revenue of $137M and 437MW billable capacity give the AMD deal real near-term financial weight, and the stock is heading into the H.C. Wainwright Global Investment Conference this month for continued investor exposure.

KEY DAILY PRICE LEVELS: VWAP anchor ~$16.90 (~est.). Expected opening range $16.40–$17.50 (~est.). 20/50-day MAs: stock has been under multi-week pressure (90-day return -43%) but is bouncing hard off the AMD news — momentum favors a short-term long. ATR(14): $1.19. Bias: long, momentum breakout.

SUPPORT & RESISTANCE: Support: $16.29 (0.5 ATR), $15.70 (1 ATR, prior swing low). Resistance: $17.48 (0.5 ATR), $18.07 (1 ATR).

WYCKOFF PHASE: Potential Phase-D markup off an accumulation base after a prolonged 90-day decline, contingent on volume follow-through.

CIFRCipher Digital Inc.
$16.72 +5.44%
Technology services (AI datacenter/HPC) · Pre-mkt Vol: 376K (avg 62.8M, 2.75x rel.) · ATR: $1.72 · Float: $6.9B mkt cap

CATALYST: Shares jumped on a data-center power-supply update as Cipher’s AI/HPC pivot accelerates; Bernstein reiterated its Buy rating on CIFR as recently as Sept 1. The company (with Fluidstack and Anthropic) is also investing $10M in Colorado City’s water infrastructure to de-risk its Barley Lake data-center site.

WHY IT’S MOVING: Stock was already up double-digits Sept 15–16 on the power-supply news; today’s follow-through gap suggests continuation buying from momentum and swing accounts rather than a fresh headline. Rebranded from Cipher Mining to Cipher Digital in February, signaling the strategic shift from pure bitcoin mining to hyperscaler HPC hosting.

KEY DAILY PRICE LEVELS: VWAP anchor ~$16.75 (~est.). Expected opening range $16.10–$17.60 (~est.). Price extended after a multi-day run — expect some give-back risk. ATR(14): $1.72. Bias: long, but size down after the recent run.

SUPPORT & RESISTANCE: Support: $15.86 (0.5 ATR), $15.00 (1 ATR, round number). Resistance: $17.58 (0.5 ATR), $18.44 (1 ATR).

Sources: Timothy Sykes News, TRDXCA pre-market scanner, Finviz.
AXTIAXT Inc
$64.30 +5.24%
Electronic technology (semiconductor materials) · Pre-mkt Vol: 205K (avg 12.1M, 2.61x rel.) · ATR: $7.25 · Float: $4.2B mkt cap

CATALYST: AXT is being added to the S&P SmallCap 600 index, replacing Matthews International, effective before the open Monday Sept 21 — a mechanical, index-fund-driven buying catalyst. Layered on top: record Q2 revenue of $47.6M on strong indium phosphide (InP) substrate demand and new supply agreements.

WHY IT’S MOVING: Index-inclusion flows plus a genuine growth story in InP substrates (used in photonics/AI optical interconnects) are compounding; the stock has been extremely volatile over the past week (swings from ~$55 to ~$93 intraday reported), so expect wide ranges. Management is also mid-way through a run of investor conferences.

KEY DAILY PRICE LEVELS: VWAP anchor ~$64.50 (~est.). Expected opening range $61–$69 (~est., unusually wide given recent volatility). ATR(14): $7.25 — among the largest ATRs in today’s scan relative to price. Bias: long into the index-inclusion window, but respect the volatility with smaller size.

SUPPORT & RESISTANCE: Support: $60.68 (0.5 ATR), $57.05 (1 ATR). Resistance: $67.93 (0.5 ATR), $71.55 (1 ATR).

Sources: Timothy Sykes News, StocksToTrade, Finviz Tech Sector scan.
WULFTeraWulf Inc.
$15.39 +5.00%
Technology services (AI datacenter/power) · Pre-mkt Vol: 426K (avg 32.2M, 4.26x rel.) · ATR: $1.27 · Float: $7.7B mkt cap

CATALYST: A 482 MW power deal in Kentucky unlocks a potential $4.0–$4.5B AI/HPC campus, and a 20-year, ~401 MW Anthropic lease at TeraWulf’s repurposed smelter site anchors an estimated $19B in contracted revenue — two of the largest hard catalysts in today’s scan.

WHY IT’S MOVING: Wall Street coverage has turned bullish with fresh Buy/Outperform ratings even after a pullback, though note this cuts against a recent wave of insider selling (CEO Paul Prager sold ~$2.35M, director Walter Carter sold ~$1.98M on Aug 31) — a headwind worth watching if the gap fades.

KEY DAILY PRICE LEVELS: VWAP anchor ~$15.40 (~est.). Expected opening range $14.90–$16.10 (~est.). ATR(14): $1.27. Bias: long, but tighter stop given the insider-selling overhang.

SUPPORT & RESISTANCE: Support: $14.76 (0.5 ATR), $14.12 (1 ATR). Resistance: $16.03 (0.5 ATR), $16.66 (1 ATR).

Research Themes

Bitcoin Miner → AI Data Center Pivot

Crypto miners are repurposing power infrastructure into long-duration, contracted AI/HPC hosting revenue — CORZ’s $14B AMD deal, WULF’s ~$19B Anthropic lease, and CIFR’s power-supply expansion are today’s clearest examples. This theme is producing the largest, most catalyst-driven pre-market gaps in the entire scan and should keep drawing momentum flow as more hyperscaler leases get announced.

Tickers: CORZ, CIFR, WULF, IREN, APLD, MARA, RIOT, CLSK, BMNR

AI Infrastructure & Chip Ecosystem Strength

Semiconductor and AI-cloud names are broadly green pre-market on continued capex enthusiasm; AXTI’s mechanical S&P SmallCap 600 inclusion (effective Monday) plus record InP substrate revenue adds an index-flow tailwind on top of the sector move. King Charles III’s AI-safety meeting with Nvidia, OpenAI and DeepMind leadership today keeps the AI narrative front and center.

Tickers: NBIS, AXTI, CRDO, MRVL, INTC, SMCI, ORCL

Rate-Path Repricing Into Quad Witching

With the 10-year yield pressing toward 5% after Wednesday’s hawkish Fed hike, and tomorrow’s quadruple-witching expiration on deck, expect volatility to stay elevated into Friday’s close even as VIX unwinds from yesterday’s spike. High-beta AI/crypto names are the most likely to see outsized swings both ways.
