Research Report

Question: You are a rigorous financial research analyst. Ground EVERY quantitative claim in data you actually pulled from the finance tools — never invent a price, multiple, or indicator. Answer the REQUEST below by:

1. Identifying the specific publicly-tradable assets (tickers) it concerns. When the request is open-ended (e.g. "top up-and-coming tech companies"), first find concrete candidates: use finance_data (action=search) to resolve names to tickers, and web search / the browser for qualitative discovery.
2. For EVERY ticker you discuss, pull real data with the finance tools:

• finance_data action=analyze — LIVE price, % returns, 52-week range position, and the indicator panel (RSI-14, MACD, SMA 50/200, VWMA-20/67, trend). Batch multiple tickers in one call.
• finance_data action=fundamentals — market cap, P/E & forward P/E, PEG, margins, revenue growth, analyst target & rating (use for valuation).
• finance_data action=quote source=pyth — fastest realtime spot price (esp. crypto) with a confidence band, when you need the very latest tick.
• finance_data action=liquidation — the VWMA-67 'true price' and leverage liquidation levels (great for crypto/timing context).
• finance_news — recent catalysts/sentiment (macro + per-ticker headlines).
• finance_insider — corporate insider (SEC Form 4) and, with scope=congress, political trades, to see informed-money flow. If scope=congress returns a browser_fallback (the free API was gated), follow it: use the browser tool on the given capitoltrades.com URL(s) and read the rendered trades table.

3. Writing a concise report: a short investment thesis for each asset (why it is interesting, grounded in the pulled price/fundamentals/news/insider data), then a summary table with columns: Ticker | Price | 1d% | 5d% | 20d% | RSI | P/E | Trend. Rank assets by thesis strength, cite notable news/insider signals, and clearly flag any ticker you could not fetch.

Executive Summary

As of Sunday, September 6, 2026, US equity markets were closed — 09-06 is a weekend day, and the last available daily bar in market data for every major index proxy is dated 2026-09-04. The session that answers "how did the market do today" is therefore Friday, September 4, 2026.

Bottom line: US large-cap stocks closed lower on a macro shock, not an earnings shock. The August jobs report came in hot — +162,000 payrolls vs. roughly a 53,000–65,000 consensus — and because the current Fed regime leans toward tightening, strong data was read as bad news: September rate-hike odds jumped from ~49–51% to 58–60.4%, Treasury yields rose (2-year 4.37%, 10-year ~4.78%), and stocks fell. Closes: S&P 500 −0.4%, Dow −0.5%, Nasdaq Composite −0.3%, Russell 2000 +0.2%. The declines were cushioned by a narrow megacap-tech rally (XLK +0.70%) led by AI/memory-chip names — SanDisk +11.9%, Micron +6.1%, AMD +4.7% — while the worst S&P laggards were earnings/regulatory casualties: Lululemon −17.4%, Guidewire ~−20%, FICO −16.7%, and an AI-disrupted software complex (UiPath, Asana).

Major Indices — Friday, September 4, 2026 (the session relevant to 09-06)

Index levels and changes are from the AP wire's 09-04 close table (AP, 9/4); ETF proxies are the last finance_data daily bars (09-04). The Dow's −271.86/−0.51% close and YTD context are independently confirmed by dowjonestoday.net, 9/4.

Why the Nasdaq Composite fell while QQQ rose: QQQ tracks the 100 largest Nasdaq names; the Composite is broader. The gap is the day's central story — megacap tech/semis up, the broad tape down.

What drove the session

1. Hot August jobs report (released Fri 9/4): +162,000 payrolls vs. ~53,000 (Dow Jones consensus, per CNBC) to ~65,000 (FactSet, per LA Times) expected; June and July revised up a combined +55,000; unemployment held at 4.1%. (LA Times/AP, 9/4; CNBC, 9/4)
2. The market repriced a Fed hike, not a cut: CME FedWatch odds for a September hike rose to 60.4% Friday from 49.4% Thursday (LA Times/AP, 9/4); CNBC cites 58% (from ~51% pre-report); Investopedia, 9/4 reports the move as ~51% → 58%. U.S. Bank's Terry Sandven called the report "leaning toward the Fed increasing rates"; LPL's Jeffrey Roach said a Sept. 16 hike "appears increasingly likely."
3. Yields rose: 2-year Treasury to 4.37% (AP) — its highest since January 2025 per CNBC; 10-year ≈4.78% (Investopedia, 9/4).
4. Rate pressure was amplified by geopolitics/energy: an intensifying six-month US–Iran war (Iran fired at Kuwait Thursday; Strait of Hormuz "effectively closed") had crude up ~9–10% on the week (LA Times/AP, 9/4).
5. The offsetting bid: AI/memory-chip catalysts (SanDisk, Micron, AMD strength; DRAM theme) and defensive utilities rotation kept the S&P's loss contained (LA Times/AP, 9/4). The session snapped a two-day winning streak (Investopedia, 9/4).

Context for the week ahead: August CPI is due Sept. 11 and the Fed decision lands Sept. 16 — the jobs print "put the outcome in the hands of next week's inflation numbers" (LA Times/AP, 9/4).

Biggest movers (Friday, 09-04, all in-window)

Large-cap / S&P 500 names

Drivers sourced from LA Times/AP, 9/4, Investopedia, 9/4, CNBC, 9/4, and the 9/4 movers tables at ainvest.com / cot-trading.com. TSLA was independently verified via finance_data (close $354.08) matching CNBC — the only single-name close double-verified against the feed. Percentage moves for GWRE/LULU/FICO/PATH/ASAN/ADBE/ZS rest on dated in-window outlet reporting, not re-quoted live prices.

The AI/memory/semis rally (the day's winning trade)

AEHR +13.1%, BLTE +13.2% (analyst initiation), SNDK +11.9%, CBRS +10.3%, COHU +10.3%, ALAB +9.8%, NBIS +7.5%, MRVL +7.1%, COHR +6.6%, STX +6.3% — data-center flash/HDD demand and AI-infrastructure optimism per the 9/4 COT-Trading and AInvest mover tables (single-source, aggregator-reported).

Dow 30 leaders/laggards (dowjonestoday.net, 9/4)

• Leaders: GS +3.34%, CRM +2.92%, MSFT +2.68%, TRV +2.23%, WMT +2.20%
• Laggards: CSCO −0.78%, DIS −0.76%, MCD −0.51%, PG −0.49%, MMM −0.26%

Whole-exchange % extremes (micro/small caps, source: stockmarketwatch.com digest, 9/4)

• Gainers: IMRN +55.4%, CDTG +47.9%, AOUT +41.5%, BIAF +40.5%, GRI +28.7%, GPRO +26.3%, AIFU +26.3%, RDIB +25.7%
• Losers: TRBG −41.5%, BANL −38.4%, IPEX −28.6%, FGL −28.0%, CMND −25.3%, WETO −22.0%, BRNX −21.6%, GWRE −21.0%

These are as-reported single-source moves with no per-share prices re-verified; treat them as the day's headline tape extremes, not as investment signals.

Sector scoreboard (S&P 500 sector ETFs, finance_data 09-04 bars)

The assembly: megacap tech strength (+0.70%) outweighed broad softness in consumer discretionary, communication services, health care, energy, financials, staples, and real estate — a "tech higher, risk appetite uneven" tape, with a modest defensive tilt into utilities.

Analysis

The day's logic was "good data is bad data" in a tightening-biased regime. A strong jobs number with upward revisions and sticky ~4%+ inflation raised the odds of a September hike to a majority (~58–60.4%), pushing the 2-year yield to its highest since January 2025. That repricing hit rate-sensitive and consumer sectors hardest — discretionary −1.33% (its worst of the session), staples, health care, financials down — which is why the Dow (−0.5%) fell more than the S&P (−0.4%).

The other half of the tape was company-specific, not macro. The biggest S&P decliners each had their own catalyst: Lululemon and Guidewire cut guidance; FICO lost its mortgage-scoring monopoly to a regulatory order; the software complex (UiPath, Asana, Zscaler, Adobe) sold off on AI-vs-SaaS disruption fears, per CNBC. The mirror-image winners — SanDisk, Micron, AMD, Astera Labs, Marvell, memory/optical names — rallied on AI-infrastructure demand. Notably, the day's worst decliners and best gainers were both largely not the macro trade; the macro trade was the modest broad-market decline.

Technically, this was a pullback inside intact uptrends, not a break. On 09-04 bars, SPY/DIA/QQQ carry "strong uptrend" labels with RSI-14 between 52.9 and 55.6, sitting at 84–94% of their 52-week ranges; IWM is the exception (RSI 48.1, negative MACD histogram, labeled downtrend), consistent with small caps running hot but fading. The S&P was still positive for the week (+0.1%) per CNBC/Investopedia.

Risks & Open Questions

• Single-source mover data: The largest-percentage movers rest on date-stamped aggregator pages (AInvest, COT-Trading, stockmarketwatch); only TSLA's close was double-verified against an independent quote feed. Two posted prices on AInvest (SanDisk ≈$1,740, Netflix ≈$78.25) are internally inconsistent with their market caps and were discarded as likely data-entry errors. The listed per-share prices for GWRE/LULU/FICO/PATH/ASAN are as-reported and were not re-quoted from the feed.
• Conflicting recap discarded: One low-credibility recap site (tickerdaily.com) claimed the S&P closed at 5,847 — inconsistent with the AP/CNBC/Barron's consensus (7,718.60) and with the ETF feed; it was not used.
• No 09-05/09-06 session exists — those are weekend days with no trading bars. No in-window source exists for "Saturday/Sunday" market action because there was none.
• Next US session: Tuesday, September 8, 2026 — Monday, September 7 is the Labor Day holiday (NYSE 2026 calendar).
• Watch items that determine whether this sell-off extends: August CPI (Sept. 11) and the FOMC decision (Sept. 16); oil/Hormuz headlines; and next week's earnings from the software and consumer names that drove Friday's declines.

US Stock Market Recap — Trading Session Friday, 2026-09-04 (as of the weekend of 2026-09-06)

Preliminary note on dating (important)

2026-09-06 falls on a Sunday — a US market holiday (weekend). US equity exchanges were closed on 09-05 (Sat) and 09-06 (Sun). The trading session associated with the request is therefore the previous US session, Friday, 2026-09-04, which is confirmed by the finance-data platform, whose most recent daily bar for every instrument queried is timestamped 2026-09-04 13:30 (session close data). All levels below are for the 09-04 session's close. No quote exists for 09-05/09-06 because those are non-trading weekend days. Quantitative data below is drawn directly from the finance_data tool; do not treat any number as modeled or recalled.

1. Major indices (ETF proxies, 09-04 session, 1-day % change)

Message from the tape (based on pulled data): The 09-04 session was a divergent / mixed one. The broad large-cap benchmark (S&P) and the price-weighted Dow closed down, while Nasdaq-100 growth (QQQ +0.18%) and small caps (IWM +0.28%) finished modestly in the green. The negative composite reading despite a positive Nasdaq-100 capture points to breadth/weight drag from outside mega-tech, consistent with the sector tables in §2.

2. Sector attribution (S&P 500 Select Sector SPDR ETFs, 09-04 session)

I pulled 1-day returns for the 11 GICS sector ETFs. Note the two distinct camps:

Drivers (only sectors that finished up on the session):

• Technology — XLK +0.70% (leader). Tech was the clear day-driver, and it is the reason the Nasdaq-100 ETF rose (+0.18%) while the broader S&P composite fell. XLK's large weight in the S&P is what kept SPY's decline contained to ~−0.4%.
• Industrials — XLI +0.41%
• Utilities — XLU +0.12% (slight defensive gain)

Draggers (largest down-movers on the session):

• Consumer Discretionary — XLY −1.33% (worst sector of the 11)
• Communication Services — XLC −1.19%
• Health Care — XLV −1.05%
• Energy — XLE −0.87%
• Consumer Staples — XLP −0.80%
• Financials — XLF −0.79% (notably, financials gave back; XLF 5-day = 0.00%)
• Real Estate — XLRE −0.72%
• Materials — XLB −0.34%

Round 0 · Finding 2

US Stock Market Recap — Session of Friday, September 4, 2026

Date note: 2026-09-06 is a Sunday; the US equity markets were also closed Monday, September 7 (Labor Day). The most recent completed and only relevant US trading session is therefore Friday, September 4, 2026. All figures below reference the Sept 4 close. My live finance-tool data confirms the final available daily bar is dated 2026-09-04.

1. Executive Summary

US stocks closed lower on Friday, September 4, 2026, after a much hotter-than-expected August jobs report revived fears that the Federal Reserve could raise — not cut — rates at its September meeting. All three headline cap-weighted indices fell, while technology names rallied in a defensive/relative-strength rotation that partially cushioned the declines. The primary macro catalyst was the August BLS payrolls print (162,000 jobs added vs. ~65,000 expected), which pushed CME FedWatch odds of a September rate hike from 49.4% to 60.4% and drove Treasury yields and oil prices sharply higher. A parallel micro-catalyst set was the semis rally (Micron, Sandisk, AMD) and a brutal single-stock miss from Lululemon (−17.4%), the S&P 500's biggest decliner of the day.

2. Verified Index Closing Levels (Session 9/4/2026)

Cross-checks confirming the figures:

• dowjonestoday.net (rebuilt/data-dated 2026-09-04) independently lists the Dow closing at 53,414.25 (−271.86, −0.51%), intraday range 53,289.88–53,635.35, and confirms the index sits 1.72% below its Aug 5, 2026 all-time closing high of 54,349.12. Source: https://dowjonestoday.net/
• My finance-data pull (action=history/quote, last daily bar 2026-09-04) gives SPY −0.385%, DIA −0.531%, QQQ +0.18%, IWM +0.278% — SPY and DIA are within rounding of the reported index moves.

Important divergence / caveat on the Nasdaq: The reported Nasdaq Composite gave back 0.3% (LA Times/AP), yet the Nasdaq-100 ETF (QQQ) closed UP +0.18% on the same bar. This is consistent with the day's rotation into large-cap technology/semis (which dominate the NDX) while the broader, more equal-weight Composite drifted lower — the same cap-vs-broad divergence noted by dowjonestoday's Dow-vs-market commentary. I am reporting both faithfully and flagging the ETF/index mismatch rather than reconciling it.

US Stock Market Recap — Session Ending September 4, 2026

A note on dates (important for accuracy)

2026-09-06 (today) is a Sunday — no US equity session occurred that day. My pulled market data confirms the most recent completed trading session is Friday, September 4, 2026 (finance_data last daily bar = 2026-09-04 for all indices; CNBC article titled "Stock market news for Sept. 4, 2026"). Per the task's own rule, Friday 09-04 is the session recapped below. Markets were also closed the following Monday (Labor Day), per Investopedia's dated banner "Updated September 04, 2026" noting markets close Monday.

Every what-happened claim below is tied to a page fetched with a visible publication/update date inside 2026-09-04 (the trading window).

Executive Summary

Friday 09-04-2026 was a down day for the large-cap indexes on hot-August-jobs-report-induced rate-hike fears, while small caps resisted the sell-off. The Dow led losses; the Nasdaq/S&P closed down for the day but still positive for the week. Growth/software and discretionary names were the biggest decliners on company-specific catalysts (guidance cuts and a Tesla Cybercab disappointment), while AI/memory-chip stocks rallied — a stark intra-market split that muted the S&P decline.

1. Major Indices — Closing Levels (session ending 09-04-2026)

Corroborating ETF data (finance_data, 1-day close on 09-04): SPY −0.39% @ $770.19; QQQ +0.18% @ $718.96; DIA −0.53% @ $534.08; IWM +0.28% @ $296.01. Directionally matches CNBC (large caps down; the Nasdaq-100 through QQQ was firmer than the broader Composite). Note the small gap between QQQ (+0.18%) and the Nasdaq Composite (−0.29%) is expected: QQQ tracks the Nasdaq-100, a different index.

Weekly context: Nasdaq +0.4% and S&P 500 +0.1% for the week; Dow −0.3% (CNBC and Investopedia both state this).

Round 0 · Finding 4

US Stock Market Recap — Session Ending 2026-09-06 (Reference Session: Friday, Sept. 4, 2026)

1. Executive Summary

Calendar note. 2026-09-06 is a Sunday in the Labor Day weekend (markets were closed Monday, Sept. 7 per the recap pages dated Sept. 4). Therefore the "session ending 2026-09-06" is the regular Friday session of Sept. 4, 2026 — consistent with multiple sources that date Sept. 4 as "Friday, September 04, 2026."

Bottom line. The Sept. 4 session was a mixed, rate-driven session. August nonfarm payrolls (+162,000 vs. consensus near ~53–56k) came in hotter than expected with upward revisions to June and July, benchmark Treasury yields jumped, the dollar rose, and short-term rate futures pricing of a September Fed hike climbed (to roughly 58–65%), rekindling rate-hike fears that weighed on the broad indices. The Dow and S&P 500 closed lower while the Nasdaq/Russell held modest gains on strength in AI/semis/memory names, which were also the day's biggest gainers. Fully 8 of the 10 star decliners were fresh post-earnings/regulatory events (Guidewire, lululemon, FICO, UiPath, Asana, Snowflake, Netflix).

I could not fetch a single authoritative, first-party close table for all four indices and per-ticker closes; the recap is assembled from the finance-data tool (primary ETF closes/returns) plus dated stock-mover pages. Figures below are individually sourced and confidence-rated. Sources disagree on some absolute numbers, noted where relevant.

2. Indices (reference session Friday, Sept. 4, 2026)

Primary data pulled via finance_data (action=history, daily bars; last trading bar = 2026-09-04):

(Source: finance_data history output, last bar 2026-09-04) — Directional read: Dow and S&P 500 down ~0.4–0.5%; Nasdaq-100 and Russell 2000 up slightly (mixed/rotational session).

Independent but conflicting published index figures (dated Sept. 4) for context — these disagree on direction/Nasdaq and should be treated as background/corroboration only:

• eOption Closing Recap, Friday Sept. 04, 2026: DJ Industrials −272.51 (−0.51%) @ ~53,413; S&P 500 −29.35 (−0.38%) @ 7,718; Nasdaq −77.07 (−0.29%) @ 26,506; Russell 2000 +7.37 (+0.21%) @ 2,975 — https://www.eoption.com/market-review-september-04-2026/
• tickerdaily ("Stock Market Today, September 4, 2026") claimed the opposite for several indices (e.g., S&P +0.31% flat 5,847) — https://tickerdaily.com/article/stock-market-today-september-4-2026-sandp-500-nasdaq-dow-close-recap — flagged as conflicting/low-credibility.

US Stock Market Recap — Session of Friday, 2026-09-04 (the trading session associated with 2026-09-06)

Timing note. Today, 2026-09-06, falls on a Sunday (confirmed by a server date: Sun, 06 Sep 2026 header returned when fetching investopedia.com). US markets were therefore closed over the weekend; the last completed US cash session relevant to this recap is Friday, September 4, 2026. Data pulled from finance_data confirms this: the latest daily bar for SPY/QQQ/DIA/IWM is dated 2026-09-04. Everything below pertains to that Friday session.

1. Executive Summary

US large-cap equities fell on Friday, September 4, 2026, after an upside-surprise August nonfarm-payrolls report (net +162,000 jobs) raised the odds that the Federal Reserve could hike — not cut — its policy rate. The S&P 500, Dow Jones, and Nasdaq Composite closed lower, Treasury yields rose (the 2-year climbed to 4.37%), and only the small-cap Russell 2000 finished in the green. Gold-standard closing levels below come from the AP News wire piece dated 2026-09-04 20:30 UTC ("Updated 4:30 PM EDT, September 4, 2026"), which I fetched directly. Individual per-ticker "biggest movers" with quoted prices could not be verified from a fetched in-window source (see Section 4); I was able to ground only the index/macro level.

2. Official Closing Levels (Session 2026-09-04)

Source: AP News, "How major US stock indexes fared Friday 9/4/2026," published 2026-09-04 — in-window. https://apnews.com/article/stock-market-dow-nasdaq-jobs-ebc11cfa2cf8baf4491bf3d4199c1d74

These reconcile cleanly with the prior session (Sept 3 close of Dow ≈ 53,686.11, from the CNBC live-blog indexing — background).

Corroborating live-tape data pulled from finance_data (finance_data, last bar 2026-09-04)

• SPY $770.19, −0.385% 1d → tracks AP's S&P −0.4%.
• DIA $534.08, −0.531% 1d → tracks AP's Dow −0.5%.
• IWM $296.01, +0.278% 1d → tracks AP's Russell +0.2%.
• QQQ $718.96, +0.18% 1d (Nasdaq-100 proxy; can diverge from the Composite, which fell 0.3%).
• Indicator panel (all vs. 14-day RSI / SMA trend, 2026-09-04): SPY RSI-14 55.6 (trend: strong uptrend); DIA RSI-14 52.9 (strong uptrend); QQQ RSI-14 53.6 (strong uptrend); IWM RSI-14 48.1, MACD histogram negative, trend: downtrend. All four ETFs sit high in their 52‑week ranges (SPY at 93.9%, QQQ 84.6%, DIA 86.8%, IWM 88.0%).

3. The Catalyst That Drove the Session (with named numbers)

The dominant driver was macro/rates, not company earnings:

Round 0 · Finding 6

I now have a comprehensive, well-dated primary recap page from stockmarketwatch.com (datePublished 2026-09-04T21:06:40Z), confirming index close levels, movers, and catalysts, plus confirmation that Sep 07 is the Labor Day holiday (US markets closed). And the finance_data daily history confirms the last trading bar for SPY/QQQ/DIA/IWM is 2026-09-04, with no bar on 09-05/06 (Saturday/Sunday).

Let me reconcile:

• stockmarketwatch digest: Dow 53,414.25 -0.51%; S&P 500 7,718.60 -0.38%; Nasdaq 26,506.99 -0.29%; Russell 2000 2,975.65 +0.25%; VIX 14.53. Confirms my finance_data ETF levels directionally consistent (SPY -0.38%, QQQ +0.18% [Nasdaq-100], DIA -0.53%, IWM +0.28% which ≈ Russell +0.25%).
• Confirms catalyst: hot August jobs report — +162,000 payrolls vs ~55,000 consensus, unemployment 4.1%, Treasury yields jumped (10Y ~4.78-4.79%), rate-hike odds rose above 60%, VIX +1.47%.
• Biggest movers listed with prices/percentages.
• FICO -16.7% on FHFA/VantageScore catalyst; semis/memory led (+6.87% memory chips theme); software lagged.
• Sep 07 Labor Day holiday confirmed (so Sept 7, 2026 is a US market holiday — also relevant to note next session is Sep 8, Monday).

Note the tickerdaily snippet oddly reported "S&P 500 closed at 5,847.32" — that's clearly inconsistent with the bulk of sources (7,718.60) and likely an indexing error in that snippet; I'll flag that source discrepancy and rely on the consistent mult-source figure of ~7,718.60 and index ETF data. Also note the "fundsipcalculator.com" snippet reporting S&P 500 ETF at 770.19 gaining +0.66% is internally inconsistent/garbled (it says S&P 500 "closed at 770.19" which is actually the SPY ETF price, and the +0.66% doesn't match), inconsistent with everything else; I'll avoid it.

Day-of-week verification: Sept 1=Tuesday → Sept 4=Friday, Sept 6=Sunday. Confirmed by last_bar 2026-09-04 across all four index ETFs (no 9/5 bar) and by multiples sources describing Sept 4 as "Friday." Labor Day 2026 is Monday Sept 7.

Now I can write the final answer.

Let me confirm the biggest movers from stockmarketwatch: gainers IMRN +55.41%, CDTG +47.94%, AOUT +41.46%, BIAF +40.53%, GRI +28.69%, GPRO +26.26%, AIFU +26.25%, RDIB +25.72%. Losers TRBG -41.45%, BANL -38.41%, IPEX -28.61%, FGL -28.04%, CMND -25.29%, WETO -21.96%, BRNX -21.55%, GWRE -21.00%. And FICO -16.7% (corporate spotlight). Confirmed in-window (page dated Sept 4).

I have enough to write the detailed, sourced report.

The date-correctness finding: 2026-09-06 is a SUNDAY — not a US trading day. Most recent completed session = Friday 2026-09-04. I should be explicit about my verification.

Confidence in day-of-week: I derived Sept 4 = Friday from the trading bars (continuous Mon-Fri bars ending 09-04, and Sept 7 being Labor Day/A market confirmation saying "Sep 07 US markets closed Labor Day"). Tradeable bars run 08-31,09-01,09-02,09-03,09-04 = Mon-Fri → 09-04 Friday. Multiple sources say "Friday, September 4, 2026."
