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 2026-09-12

There was no US stock market session on 2026-09-12: it is a Saturday, and every instrument pulled carries a last daily bar of 2026-09-11 with no 09-12 bar. The most recent completed US cash session was Friday, 2026-09-11, and it was a broad relief rally that snapped a four-session losing streak — S&P 500 +0.86% to 7,656.98, Dow +0.98% to 52,578.27, Nasdaq Composite +0.96% to 26,333.04, Russell 2000 +0.45% to 2,903.94 — while all four still finished the holiday-shortened week lower (S&P −0.8%, Dow −1.6%, Nasdaq −0.7%). It ran on a mostly in-line August CPI print, a ~2–3% retreat in crude, and blowout tech-hardware earnings, against a backdrop of Fed rate-hike odds jumping to ~90% into the following week's FOMC.

Calendar verification: every session recap carries a "Friday, September 11, 2026" dateline (investrade.com, published 2026-09-11T20:08:15Z; eoption.com, stockmarketwatch.com, datePublished 2026-09-11T21:06:44Z), and the NYSE 2026 calendar shows no closure on 09-11 or 09-12 — Labor Day (09-07) was the last holiday and Thanksgiving (11-26) the next (nyse.com). No dated in-window (2026-09-12) source describing a US trading session exists, because none traded.

Last Session Close — Friday, 2026-09-11

Index levels and percentages are tool-sourced (finance_data quote/analyze; all last_bar 2026-09-11 13:30 ET). Independent closing recaps report the same four percentage moves and the levels 7,656 / 26,333 / 2,903; the Dow print is garbled there ("52,6572"), so the 52,578.27 tool value is used (investrade.com, stockmarketwatch.com). ETF proxies agree to within ~0.1pp: SPY 764.29 +0.852%, DIA 525.79 +0.968%, QQQ 714.88 +0.873%, IWM 288.89 +0.414%.

Rates and volatility (2026-09-11): VIX 15.84, −11.21% on the day (but +10.6% over 5 days — a one-day fear unwind, not a low-vol regime). 10-year yield proxy TNX 4.976%, +0.627% in index terms, from a 4.945 prior close (~+3bp on a close basis), sitting at the 99.1st percentile of its 52-week range. Caveats: the tool reports the change in the yield index, not basis points, and one source (EconCurrents) described the day's 10-year move as lower — the close-to-close tool data supports higher.

Sector Breakdown — 2026-09-11

Nine of eleven sectors closed higher, led by Technology, Industrials and Communication Services, with Health Care and Utilities the only decliners — matching the published session narrative (investrade.com). Investopedia instead named Communication Services, Consumer Discretionary and Information Technology as leaders (investopedia.com); the tool-sourced ETF data above is the tiebreaker. Note the divergence: Energy is the best 20-day sector (+6.68%) but only middling on the day, consistent with crude pulling back.

The Biggest Movers

Tool-verified (prices and moves from finance_data, bar 2026-09-11):

RSI-14 values were returned inconsistently across separate tool pulls for the same tickers (e.g. ACVA 82.2 in one call, 78.8 in another) and are therefore omitted rather than presented as a single number.

Micro-cap extremes — single-source, NOT tool-verified (stockmarketwatch.com, digest dated 2026-09-11T21:06:44Z): gainers MKDW +50.35%, FEIM +41.77%, GTBP +39.92%, SXTC +29.79%, KRSA +29.54%; decliners UCAR −32.68%, CVV −24.77%, GCTK −21.52%, SGLY −19.90%, GRML −17.59%, ADIL −17.26%, PMTS −16.49%, SMR −15.82%. The character of this list — sub-$5 to ~$90 small caps with 30–95% swings — confirms the true session extremes were micro-cap, not large-cap, which is consistent with sub-1% index gains.

What Drove It

In-window (2026-09-12) items are weekend wires only, since equities were shut: "US restricts air defense windows for tankers passing through Hormuz – FT" (04:02Z) and "High oil prices could prompt ECB to increase rates further: Martin Kocher – FT" (04:04Z) — FinancialJuice, FinancialJuice. These are next-session setup, not drivers of a 09-12 session.

Analysis

The 09-11 session was a rebound inside a downtrend, not a trend reversal. Every index was green on the day but negative on both the 5-day and 20-day windows, and the Russell 2000's −4.88% 20-day return with small caps lagging the day (+0.45% vs Dow +0.98%) shows the advance was not distributed down-cap. The sector tape tells the same story: the only two sectors positive over five days were Technology (+0.91%) and Energy (+0.81%), while Health Care (−4.56%) and Materials (−3.17%) were the week's worst. What rallied Friday was cyclicals and defensives being sold — a classic risk-on relief rotation, validated by the VIX dropping 11.2% in a single session while still sitting 10.6% higher over five days.

The driver mix was contradictory and the market chose the benign half of it. The CPI headline matched expectations, but core came in hot at +0.3% m/m vs +0.2% expected and rate-hike odds repriced sharply higher, and Michigan sentiment missed badly with 1-year inflation expectations at 4.6%. Equities looked past both because crude pulled back 2–3% from a spike that had been doing the real damage to the inflation outlook. That is a fragile basis for a rally: the oil retreat was repositioning, not resolution, and the geopolitical supply story (pipeline attack, Hormuz tanker restrictions) was still escalating into the weekend.

The single highest-conviction signal in the session was tech hardware: HPE +12.44% and DELL +11.98%, the latter closing at 99.9% of its 52-week range, with AMD, INTC, SMCI and QCOM all higher. That is a real earnings/capex-driven bid, not a macro bounce, and it is the leg of this session most likely to persist.

Risks & Open Questions

• The "rate hike" framing is single-source-heavy. Both Investrade and Investopedia report ~87–90% odds of a rate hike at the 09-16 FOMC and an expected move to 3.75–4.00%. Verify against CME FedWatch directly before acting; this is a hawkish regime claim resting on two dated recaps.
• Dow closing level is inconsistent across sources — tool 52,578.27, one digest 52,573.29, another garbled "52,6572." Use the tool value; the percentage move (+0.98%) is agreed by all.
• ACVA/Copart ($1.9bn) is secondary-source only. The price move (+44.18%) is tool-verified; the deal detail is not. Pull the 8-K and SC TO-C from SEC EDGAR to confirm.
• Contradicted source discarded: tickerdaily.com asserts the S&P closed −1.2% at 5,847.32 on 09-11. Tool data and every other source show +0.86% at 7,656.98. Excluded; page itself not fetched, so its status is unverified.
• Unestablished catalysts: no dated explanation was retrieved for UNH −2.37%, PANW −2.32%, YUM −2.10%, IBM +3.96%, SMCI +7.28%, or CASY's 18.85% five-day collapse. A search snippet referenced analyst upgrades on 09-11 for META, CAT, YUM, NBIS and CASY; that page was not fetched and no move is attributed to it here.
• Breadth (advancers/decliners, new highs/lows) was not obtained — no source in this run carries the tape. Sector breadth (9 of 11 green) and cap-tier breadth (large caps beat small caps) are the only breadth proxies available.
• RSI and trend labels are unreliable across pulls — the same tickers returned materially different RSI-14 values in separate calls, so no overbought/oversold read is asserted.

Claims without independent support

These statements appear in the narrative above but are not backed by text retrieved from a source. SELF-REPORTED means the only thing asserting it is the swarm's own worker output — the narrative was written from that output, so it corroborates nothing. Treat all of these as unverified.

Detailed Findings

Round 0 · Finding 1

US Market Recap — Most Recent Completed Session

Prepared 2026-09-12. Trade date of the recap session: Friday, 2026-09-11.

1. Executive Summary

2026-09-12 is a Saturday. The US cash equity market was NOT open. The most recent completed session was Friday, 2026-09-11, when all four major indices closed higher, snapping a four-session losing streak, even as each index finished the holiday-shortened week lower. The rally was driven by a mostly in-line August CPI print and a retreat in oil prices.

I was unable to find any in-window (published 2026-09-12) market-recap source — a targeted search for 2026-09-12 market coverage returned only unrelated evergreen pages. All session-specific sourcing below is therefore dated 2026-09-11, which the mission manifest permits as a valid driver date; every one is labeled with its date, and no 09-11 source is used to make a claim about 09-12 trading.

2. Calendar Verification (load-bearing step)

Finding: 2026-09-12 is a Saturday; the market was closed for the regular weekend, not a holiday. (Confidence: high)

Therefore: all "today's market" data below is labeled as the 2026-09-11 session, and I make no claim that any cash equity traded on 2026-09-12.

3. Key Findings — Index Levels (session 2026-09-11)

All values below are from finance_data (action=analyze and action=quote), with last_bar = 2026-09-11.

US Equity Market Recap — Session of Friday, 2026-09-11 (the most recent completed session as of 2026-09-12)

1. Executive Summary

2026-09-12 was NOT a US cash-equity trading day. Every instrument I pulled from finance_data carries a last_bar of 2026-09-11 and no bar for 2026-09-12 — SPY, DIA, QQQ, IWM, SPX, DJI, IXIC, RUT, VIX and TNX all terminate at 2026-09-11 (tool output, finance_data action=analyze). 2026-09-11 was therefore the last session, and all data below is labelled with that trade date. This is a weekend answer, not a "today's market" answer.

The session was a broad rebound: US stocks opened higher and stayed there, snapping a four-day losing streak for the S&P 500, Dow and Nasdaq, though all three still finished the week lower. The rebound came despite a hotter-than-expected core CPI print that pushed Fed rate-hike odds for the following week's FOMC to ~90%, and despite a 10-year Treasury yield closing at the very top of its 52-week range. The offset was a ~3% retreat in Brent crude, which relieved the energy-driven inflation trade and let technology lead. Volatility collapsed, with the VIX down more than 11%.

All figures below are from finance_data action=analyze (batch SPX,DJI,IXIC,RUT,VIX,TNX), each with last_bar: 2026-09-11.

Independent cross-check: Investrade's closing recap, published 2026-09-11T20:08:15+00:00 (datePublished in its JSON-LD), reports DJ Industrials +508.71 (+0.98%) to 52,657; S&P 500 +65.15 (+0.86%) to 7,656; Nasdaq +251.31 (+0.96%) to 26,333; Russell 2000 +12.99 (+0.45%) to 2,903 — consistent with the tool output to the reported precision.

US Market Recap — Session of Friday, 2026-09-11

0. Trading-calendar verification (this comes first, deliberately)

2026-09-12 is a Saturday. The US cash equity market did not trade on 2026-09-12. The most recent completed session is Friday, 2026-09-11, and every figure below is stamped to that trade date.

Evidence, from tool output rather than assumption:

• Every finance_data analyze response in this run returned "last_bar": "2026-09-11 13:30:00" and a next-most-recent bar of 2026-09-10 — i.e. the data vendor's last daily bar is 09-11, not 09-12 (tool output, finance_data analyze SPY,DIA,QQQ,IWM; XLK…XLC; TLT,IEF,VIXY,UVXY,SHY; HPE,DELL,INTC,ORCL,ADBE,KR,NVDA,MU,AMD).
• The session recap page I fetched is headlined "Closing Recap Friday, September 11, 2026" with JSON-LD datePublished: 2026-09-11T20:08:15+00:00 — https://investrade.com/market-review-september-11-2026/
• A search result states the NYSE/Nasdaq 2026 holiday schedule "does not include 11th September as a market holiday," with the next closure after Labor Day (Sep 7) being Thanksgiving (Nov 26) — https://dhan.co/blog/us-stocks/is-the-us-stock-market-closed-on-9-11-11th-september-2026/ (search snippet, undated page → background corroboration only).

The week was holiday-shortened (Labor Day Mon 2026-09-07), which is why the weekly figures below cover a four-session week.

1. Index levels and 1-day moves — session of 2026-09-11

Important limitation: finance_data has no index symbol coverage in this environment. ^GSPC, ^DJI, ^IXIC, ^RUT and ^SPX all returned "no data … on any exchange (tried: NASDAQ, NYSE, AMEX, … CBOE …)". I therefore report (a) ETF proxies pulled live from finance_data, and (b) index levels from a dated page I fetched. I have labelled which is which.

⚠️ Source defect, flagged not smoothed over: the Investrade table prints the Dow close as 52,6572 — an apparent typographical garble. I am reporting the digits as printed (52,657) and explicitly flagging the Dow closing level as uncertain. A separate search snippet (Zacks, article dated 2026-09-11, describing the prior session) gives the Dow's 09-10 close as 52,064.1 after a 316.56-point (0.6%) drop — https://www.zacks.com/stock/news/2988271/stock-market-news-for-sep-11-2026. BACKGROUND ONLY (describes 09-10, not the recap session).

Round 0 · Finding 4

US Market Recap — Session of Friday, 2026-09-11 (prepared 2026-09-12)

1. Executive Summary

2026-09-12 is a Saturday. The US cash equity market did not trade on 2026-09-12, so there is no "today's session" to report. The most recent completed US cash session is Friday, 2026-09-11, and every session figure below is labelled with that trade date. (Day-of-week confirmed by independent calendar sources: https://howlongagogo.com/day-of-the-week/september-12-2026 and https://www.wincalendar.com/Calendar/Date/September-12-2026 — both state 2026-09-12 is a Saturday.)

The 2026-09-11 session was a relief rally that snapped a four-day losing streak, but the week still closed lower. All four major averages rose, led by the Dow (+0.98%); volatility collapsed (VIX −11.21% to 15.84); energy was the main drag as crude retreated.

Critical caveat on the "overnight / outside-US-hours / weekend" portion of the task: I was unable to retrieve any page published on 2026-09-12, and I was unable to retrieve Asian or European index closes, or US index futures levels. Those specific asks are reported below as UNFETCHED, not filled from memory.

2. Trading Calendar Verification

Confidence: High.

3. Index Levels and 1-Day Moves — Trade Date 2026-09-11

Closing levels and percentage moves as published for the 2026-09-11 close:

A second independent recap gives the same percentage moves (Dow 0.98%, S&P 500 0.86%, Nasdaq 0.96%, Russell 2000 0.45%) and rounds the levels to 52,657 / 7,656 / 26,333 / 2,903 — the Dow level on that page contains an obvious typographical corruption ("52,6572"), so I treat the 52,573.29 figure above as the reliable one: https://www.eoption.com/market-review-september-11-2026/

Round 0 · Finding 5

US Market Session Recap — as of 2026-09-12

⚠️ READ FIRST — SCOPE OF WHAT I COULD AND COULD NOT VERIFY

The finance tool budget for this run was exhausted before I could complete the core data pulls. I was unable to fetch a single major index level, the sector breakdown, the 2-year yield, DXY, Fed funds futures odds, or a genuine biggest-movers list. Everything below is drawn only from what actually returned successfully, and I have flagged every gap explicitly rather than filling it. I did not run a browser/web fetch at all, so there are no external editorial sources in this report — the only URLs I can cite are the ones the news tool itself returned.

1. Executive Summary

• 2026-09-12 was a Saturday. The US cash equity market did not trade. Every session figure below is for the last completed session, Friday 2026-09-11. (Confidence: High — see §2.)
• The 2026-09-11 session was risk-on, on the evidence of the four index ETFs I could pull: SPY +0.85%, QQQ +0.87%, DIA +0.97%, IWM +0.41%, with the VIX falling −11.21% to 15.84. (Confidence: High for the ETF/VIX values; the index levels themselves were not fetched.)
• The dominant macro regime is an oil-supply/geopolitical shock, not a US data story. USO is +23.89% over 20 sessions and sits at the 91.2nd percentile of its 30-bar range. The 2026-09-11/12 headline flow is dominated by drone attacks on Saudi oil infrastructure attributed to Iraq, Hormuz tanker air-defense restrictions, and Saudi restraint. (Confidence: High on the price data; Moderate on causal attribution — most headlines I retrieved are timestamped after the 9/11 close.)
• I could not verify that ANY US economic data release (CPI, PPI, jobs, retail sales, sentiment) or Fed communication landed on 2026-09-11 or 2026-09-12. No such item appeared in the news feed I pulled. This is a null finding, not a claim that none occurred — I lacked the sources to check the economic calendar. (Confidence: Low — absence of evidence here.)
• Sector leadership/laggard breakdown: NOT OBTAINED. No sector ETF or sector-index data was fetched. The mission's sector requirement is unmet.

2. Trading-Calendar Verification (High confidence)

2026-09-12 was a Saturday; the US cash equity market was closed.

Two independent lines of evidence from this run:

1. Direct calendar arithmetic on the Gregorian calendar: 1 January 2026 falls on a Thursday; 1 September 2026 therefore falls on a Tuesday; 11 September 2026 is a Friday and 12 September 2026 is a Saturday.
2. The tool data itself terminates at 2026-09-11. Every finance_data analyze result returned "last_bar": "2026-09-11 13:30:00" — the 13:30 UTC timestamp is the 09:30 ET daily-bar open. No bar exists for 2026-09-12 across SPY, QQQ, DIA, IWM, TLT, IEF, GLD, USO, UUP, NVDA, AAPL, MSFT, TSLA or XOM.

Round 0 · Finding 6

US Market Recap — Session of Friday, 2026-09-11 (the most recent completed session as of 2026-09-12)

1. Trading-calendar verification (done first)

2026-09-12 was NOT a trading day. It was a Saturday. I verified the day-of-week directly rather than assuming it: a browser eval of new Date('2026-09-12T12:00:00Z').toUTCString() returned "Sat, 12 Sep 2026 12:00:00 GMT", and the same call returned "Fri, 11 Sep 2026" for 2026-09-11 and "Thu, 10 Sep 2026" for 2026-09-10.

This is corroborated by the data itself: every daily bar returned by finance_data in this run carries "last_bar": "2026-09-11 13:30:00" (ET) — SPX, DJI, IXIC, RUT, SPY, DIA, QQQ, IWM, all 11 sector ETFs, TNX, IEF, TLT and every single-stock quote. No series has a 2026-09-12 bar.

→ All session data below is for the trade date 2026-09-11 (Friday). No US cash equity session occurred on 2026-09-12. Any "market today" framing for 09-12 would be false.

2. Major indices — 2026-09-11 close

All values from finance_data action=quote (interval 1d, last bar 2026-09-11).

Index symbol note: the caret forms (^GSPC, ^DJI, ^IXIC, ^RUT, ^VIX, ^TNX) all returned "no data on any exchange" and are flagged as unfetched in that form; the bare symbols above resolved successfully (SPX→CBOE, DJI→TVC, IXIC→NASDAQ, RUT→CBOE).

ETF proxies cross-check the same session and agree (all last bar 2026-09-11): SPY 764.29, +0.852%; DIA 525.79, +0.968%; QQQ 714.88, +0.873%; IWM 288.89, +0.414%.

Shape of the tape: a broad, index-wide up day led by large-cap tech/industrials, with small caps (RUT +0.45%) lagging materially. Every index is still negative over both 5d and 20d — i.e. 09-11 was a rebound inside a downswing, not a new high. The Russell 2000's −4.877% 20d is the weakest of the four.

Investigation Trail

Round 0

• Was the US stock market open on 2026-09-12 (verify day of week and any NYSE/Nasdaq holiday or closure), and if it was closed, what were the official closing levels and 1-day percentage changes for the S&P 500, Dow Jones Industrial Average, Nasdaq Composite, and Russell 2000 on the most recent completed session (expected 2026-09-11)? Pull the actual index quotes/analytics via finance_data for BOTH dates 2026-09-11 and 2026-09-12 and report whatever the tools return.
• What were the biggest individual US stock movers in the session dated 2026-09-11 through 2026-09-12 (largest 1-day percentage gainers and losers among S&P 500 / Nasdaq-100 constituents)? For each of the top movers, pull the live/close price, 1-day %, 5-day %, 20-day %, RSI-14 and trend from finance_data analyze, and report them with tickers.
• What macro catalysts drove the US market session on 2026-09-11 through 2026-09-12? Specifically: which US economic data releases (CPI, PPI, jobs, retail sales, sentiment, Fed speakers/FOMC-related communications) landed on those two dates, what did the 10-year Treasury yield, 2-year yield, DXY dollar index, VIX, and Fed funds futures-implied rate-cut odds do over that window, and what macro headlines published 2026-09-11..2026-09-12 were cited as market drivers?
• Which US equity sectors led and lagged during the session dated 2026-09-11 through 2026-09-12, and what was market breadth (advancers vs decliners, new highs vs lows)? Pull sector ETF performance (e.g. XLK, XLF, XLE, XLV, XLI, XLP, XLU, XLY, XLB, XLRE, XLC) for that window via finance_data analyze and report each ETF's 1-day and 5-day % move.
• What company-specific catalysts moved individual US stocks on 2026-09-11 through 2026-09-12 — earnings reports, guidance changes, M&A announcements, FDA/regulatory decisions, analyst upgrades/downgrades, index-inclusion changes, or executive departures — published on those two dates? For each catalyst name the company, ticker, headline, publication date, source URL, and the stock's 1-day % move pulled from finance_data.
• What happened overnight and outside US cash hours around 2026-09-11..2026-09-12 that set up the US session or changed the weekend outlook: Asian and European index closes on 2026-09-11, US equity index futures levels on the evening of 2026-09-11 and at any point on 2026-09-12, plus any headlines published 2026-09-12..2026-09-12 (geopolitics, tariffs, weekend policy news, major corporate announcements) that would move markets at the next open?
