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:

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.
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.

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.

REQUEST: How did the US stock market perform today, including the major indices, the biggest movers, and what drove them?

Executive Summary

The US stock market did not trade "today" — 2026-10-11 is a Sunday and the cash equity market was closed. The last completed session was Friday, 2026-10-09, and it was a broadly higher, low-volatility day: S&P 500 +0.60% to 7,811.54, Dow +0.83% to 51,654.95, Nasdaq Composite +0.64% to 27,366.17, Russell 2000 +0.46% to 2,806.98, with VIX at 14.84 (−3.70%). Nine of eleven S&P sectors closed green.

The day's dominant driver was a single corporate event: SpaceX agreed to buy ~$8 billion of nationwide 800 MHz low-band spectrum from Grain Management, which crushed the three major US carriers (T-Mobile −13.27%, AT&T −10.82%, Verizon −10.14%) and sent tower REITs sharply higher (Crown Castle +15.6%, American Tower +9.3%, SBA Communications +7.3%). The index gain itself was a tech rebound off Thursday 10/8's AI-revenue scare, into the bank-earnings kickoff.

Weekend (2026-10-10/11) news is geopolitical, not market-moving for a session that never opened — air strikes on Saudi airports, a declared Russia–Ukraine "energy truce," and a widely-circulated Yahoo/Dalio piece on long-bond yields "past 5%." Those shape Monday 10/12, not "today."

Vendor delta flagged: the tool's Dow feed prints 51,660.18; both cash-index sources print 51,654.95. Both reported rather than blended.
S&P 500 closed ~0.09% under its record close set three days earlier (AP News snippet, apnews.com, 10/9/2026 — snippet only, page bot-blocked).
Sector winners: Real Estate XLRE +1.86%, Health Care XLV +1.58%, Cons. Disc. XLY +1.02%, Financials XLF +0.92%, Utilities XLU +0.83%. Losers: Comm. Services XLC −1.51% (the telecom selloff), Energy XLE −0.25%.
Breadth nuance: on the day equal-weight (RSP +0.55%) ≈ cap-weight (SPY +0.60%) — not a narrow tape. But over trailing 20 sessions SPY +1.87% vs RSP −0.85% (~2.7 pp), and IWM −3.44% — the month's advance has been narrow/mega-cap-led.

Mega-cap/large-cap moves the same session (tool-pulled, 1d %): PLTR +5.17% ($209.05)¹, COIN +4.30% ($179.39), ORCL +3.96% ($141.40), AMZN +3.29% ($262.43), MSFT +2.38% ($535.07), TSLA +2.05% ($382.70), UBER +2.00% ($71.51), GOOGL +0.97% ($351.66) — versus INTC −2.22% ($104.70), SMCI −2.14% ($41.86), AMD −2.03% ($608.10), NFLX −1.77% ($70.30), AAPL −1.11% ($336.64), TSM −1.02%, NVDA −0.52% ($229.28), META −0.31% ($718.67). The split — software/cloud/AI-adjacent up, semis and hardware down — is the signature of a rebound from a chip-led selloff, not a uniform rally.

¹ Flag: one tool round resolved PLTR to its Toronto (TSX) line ($15.74, +5.14%) rather than the US listing. The $209.05 / +5.17% figure comes from the quote feed; treat the US line as quote-sourced, not analyze-verified.

Headline-reported movers (dated 2026-10-09, from finance_news, not independently re-priced by the tool): NVAX +16%, MRNA +11%, MRK +3%, CRCL +7%, ACHR +5%, JOBY −9%.

What Drove It

Driver	Detail	Evidence (dated in-window)
SpaceX/Starlink spectrum deal (the day's defining event)	SpaceX agreed to pay ~$8B for up to 14 MHz of paired 800 MHz spectrum from Grain Management (a portfolio originating from T-Mobile), pending FCC approval. Carriers repriced as competitive threat; towers repriced as beneficiaries — Bernstein's Madison Rezaei called CCI the "best beneficiary."	portfolio-terminal.com (2026-10-10), Yahoo/SiriusXM (2026-10-09), tikr (2026-10-11). Moves independently confirmed by `finance_data`.
Tech rebound off Thursday's OpenAI scare	Oct 8: FT reported OpenAI's annualized revenue was ~$20B below prior signals; Nasdaq −1.25%, PHLX Semiconductor −3.39% (AVGO −4.35%, MU −4.79%, NVDA −2.94%). Friday recovered it.	portfolio-terminal.com (2026-10-10); echoes in WSJ live coverage headline (snippet).
Fastly upgrade	Oppenheimer → Outperform, $35 PT, citing larger client contracts, AI-agent traffic and cybersecurity demand; a Comcast/Peacock edge-platform partnership also cited.	FMP (2026-10-09), Yahoo (2026-10-10).
Earnings-season positioning	Week closed higher with traders eyeing the bank kickoff — JPMorgan, Morgan Stanley, Wells Fargo reporting the following week.	Stocktwits/Yahoo (2026-10-09T22:53Z).
Bond-market tension (background, not the day's driver)	10-yr at 5.243%, 91.5th percentile of its 250-bar range; long bonds past 5% flagged as a bubble risk.	Yahoo Finance (2026-10-11T10:45Z) — weekend, post-close.
Micro-cap movers with no catalyst	WFF (+499.5%, $18.6M mkt cap, 31.7% float), ZYBT (8.8% free float), QSI (short-covering), KLRA — sources explicitly state no news on file; low-float/momentum dynamics.	stocksetups.com (datePublished 2026-10-09T21:31Z), FMP (2026-10-09).

Other in-window catalysts: Delta Air Lines ~−4% premarket after its first earnings miss in two years and a 2026 profit-outlook cut on high fuel costs (TheStreet live blog, Oct 9 via Wayback 20261009121955); oil fell on US–Iran de-escalation (WTI −0.64% to $90.90, Brent −1.08% to $103.20, same source); a soft University of Michigan consumer-sentiment print the same morning (Vista Partners, pub. 2026-10-09T20:53Z).

Weekend tape (2026-10-11) — shapes Monday, not today: Houthi missile/drone strikes on Riyadh's King Khalid airport with claims against Dammam airport/Aramco facilities; a declared Russia–Ukraine "energy truce"; OpenAI's $20B revenue problem (moby.co via Yahoo, financialjuice wires dated 2026-10-11).

Analysis

This was a headline-driven, not a macro-driven, session. No US economic print was tied to the move by any dated in-window source found; the strongest attribution chain runs through the SpaceX spectrum deal (carriers down, towers up — a clean, tool-confirmed +/− 10–16% pair) and the reversal of Thursday's OpenAI/chip selloff. The sector map confirms it: the only sizable decline was XLC −1.51%, which is the telecom complex.

The single-day breadth was healthy; the month's is not. RSP ≈ SPY on 10/9 and 9/11 sectors green, yet over 20 sessions SPY beats RSP by ~2.7 pp and small caps are down 3.3%. That is a mega-cap-led advance underneath a broad day — the fragility signal is in the 20-day column, not the 1-day column.

Three independent data-quality problems should temper confidence in any single number. (1) The Dow has a ~5-point vendor split (51,654.95 vs 51,660.18). (2) tickerdaily.com published an S&P level of 5,847.29 and a 10-yr of 3.92% that contradict every other source and the tool — it was fetched and excluded as unreliable. (3) Several causal attributions (WSJ, AP, Barron's, TheStreet) are search-snippet-level and were not opened; they are labeled as such.

A note on the required table's P/E column: no fundamentals call was made for any ticker, so P/E is reported as "not fetched" rather than estimated, per the no-invention constraint.

Risks & Open Questions

Weekend geopolitical risk is live into Monday 10/12. Air strikes on Saudi airports and a Russia–Ukraine energy truce broke after Friday's close; Monday's open — the first session you can actually trade off this — is not in scope of the data above and no dated in-window source establishes its direction.
The 10-year at 5.24%, 91.5th percentile of range, is the standing valuation risk; the 2026-10-11 Dalio "bubble" piece is a weekend opinion, not a priced-in event.
No dated in-window source was found for a named US macro release (CPI/PPI/jobs/Fed) driving the 10/9 session; the soft consumer-sentiment reference is secondary-media only.
Unverified items: TMUS was resolved by finance_data in one round but returned "no data" in another (the −13.27% is confirmed via finance_data in the round that succeeded and cross-checked against portfolio-terminal). PLTR's US-vs-TSX listing ambiguity is flagged above. NVAX, MRNA, MRK, CRCL, ACHR, JOBY, FSLY's move sizes (in the headline set) are finance_news-reported; only FSLY was independently tool-priced (+15.86%).

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.

Round 0 · Finding 1

US Equity Market Wrap — Reference Session: Friday, 2026-10-09

1. Date confirmation (REQUIRED)

Today, 2026-10-11, is a SUNDAY. US cash equity markets were CLOSED. Verified by day-of-week computation: new Date('2026-10-11T12:00:00Z').getUTCDay() = 0 (Sunday), while 2026-10-09 = 5 (Friday) — computed via browser eval, not recalled.
Corroborated by the data itself: every instrument's last daily bar is 2026-10-09 13:30:00 (UTC = 09:30 ET, the session open stamp) — SPY, QQQ, IWM, IXIC, NDX, RUT, VIX, TNX all terminate there (finance_data quote/analyze).
Therefore the reference session for all performance figures below is Friday, 2026-10-09. No 2026-10-10 or 2026-10-11 cash session exists. (2026-10-10 is a Saturday.)

2. Major index levels & 1-day returns — 2026-10-09 (all via `finance_data` quote, `exchange=TVC`, bar 2026-10-09 13:30)

Index	Ticker used	Close	1d %	Source
S&P 500	SPX (TVC)	7,811.54	+0.595%	`finance_data` quote
Dow Jones Industrial Avg	DJI (TVC/DJ)	51,654.95	+0.826%	`finance_data` quote
Nasdaq Composite	IXIC (NASDAQ)	27,366.17	+0.636%	`finance_data` quote
Russell 2000	RUT (TVC)	2,806.98	+0.46%	`finance_data` quote
Nasdaq-100 (context)	NDX (NASDAQ)	30,883.15	+0.512%	`finance_data` quote

Cross-checks (ETF proxies, same session, finance_data analyze): SPY +0.60%, DIA +0.872%, QQQ +0.494%, IWM +0.494%. The index %-changes align with their ETF proxies, confirming they are all for the 2026-10-09 session.

Source ambiguity flagged: a second S&P feed (SPX500, FOREXCOM) printed 7,817.33 / +0.596% and a second Dow feed (DJI, FOREXCOM) printed 51,709.6 / +0.918%. The TVC values are used as primary because they carry the correct 2026-10-09 13:30 bar timestamp; the FOREXCOM CFD values differ by ~6–55 points. Both are quoted here rather than silently picking one.

3. Volatility & rates (REQUIRED)

VIX: 14.84, −3.699% (1d) — finance_data quote, symbol VIX, exchange CBOE, bar 2026-10-09 07:15. VIX 20-day change −6.31%, sitting at the 6.7th percentile of its 250-bar range (range 13.38–35.30) → subdued. Direction corroborated by vol ETPs: VXX −1.45%, VIXY −1.21%, UVXY −1.92% (same session).
10-year Treasury yield: 5.243% (TNX, TVC), 1-day +0.249%; alternate feed US10Y = 5.242%. Yield is at the 91.5th percentile of its 250-bar range (3.947–5.364), i.e. near cycle highs. This is consistent with the in-window Yahoo headline that "long-dated bonds push past 5%" (below).

Round 0 · Finding 2

US Equity Market Wrap — Reference Session: Friday, 2026-10-09

Data pulled via the finance_data tool. The tool's daily bars all terminate at last_bar = 2026-10-09 13:30:00 (i.e., 09:30 ET), and no bar exists for 2026-10-10 or 2026-10-11.

1. Executive Summary

2026-10-11 was NOT a trading day. It is a Sunday (2026-10-09 was a Friday), and the finance_data tool returned no daily bar dated 2026-10-10 or 2026-10-11 for any ticker. US markets were closed. The most recent completed session is Friday, 2026-10-09. All performance figures below refer to that session. (Calendar inference from the tool's last-bar dates: every series ends 2026-10-09.)
The reference session was a broadly positive, low-volatility, risk-on day: the S&P 500 rose +0.60%, the Nasdaq Composite +0.64%, the Dow proxy +0.87%, and small caps +0.49%. Nine of eleven S&P sector SPDRs closed higher.
Volatility was low and falling: VIX closed at 14.84, −3.70%.
Participation nuance: on the day, equal-weight (RSP +0.55%) and cap-weight (SPY +0.60%) were nearly identical — i.e., not a narrow mega-cap-only tape on 10-09. But over the trailing 20 sessions cap-weight has beaten equal-weight by ~2.7 pp (SPY +1.87% vs RSP −0.85%), a narrow-participation signature built over the month, even though the single day was broad.
Sector rotation: the day was led by rate-sensitive/defensive groups — Real Estate (XLRE +1.86%), Health Care (XLV +1.58%), Consumer Discretionary (XLY +1.02%), Financials (XLF +0.92%), Utilities (XLU +0.83%) — while Communication Services (XLC −1.51%) and Energy (XLE −0.25%) lagged.
⚠️ Major gaps: the actual Dow Jones Industrial Average and Russell 2000 index levels, the 10-year Treasury yield (^TNX), the advance/decline line, and individual-stock movers could not be fetched (see §7–8). No in-window news catalyst could be retrieved.

2. Reference Session Determination (open/closed statement)

Check	Result	Evidence
Most recent completed session	2026-10-09 (Friday)	Every `finance_data` series (SPX, NDX, IXIC, SPY, DIA, IWM, all 11 sector ETFs, VIX, RSP) ends at `last_bar = 2026-10-09 13:30:00`
Was 2026-10-11 a trading day?	No — markets closed (weekend/Sunday)	No bar dated 2026-10-10 or 2026-10-11 exists in any series returned
Was 2026-10-09 a trading day?	Yes	Full session bar present for all series

Statement: 2026-10-11 fell on a weekend (Sunday) and the US equity market was closed; the figures below describe the last completed session, Friday 2026-10-09.

Round 0 · Finding 3

US Equity Market Wrap — Reference Session: Friday, 2026-10-09

1. Was the market open on 2026-10-11? — No. Closed.

2026-10-11 was a Sunday, so US equity markets were closed. Two independent lines of evidence:

The finance_news feed (financialjuice) carried a headline dated 2026-10-11 that explicitly says an event occurred "on Sunday" — "injuries reported in assault on King Khaled airport in Riyadh on Sunday" (published 2026-10-11T16:16Z, https://www.financialjuice.com/News/9800630/...).
Every market-data series returned by the tools ends at bar timestamp 2026-10-09 13:30:00 (see finance_data action=analyze on SPX, DIA, QQQ, VIX — each last_bar: 2026-10-09 13:30:00), i.e. the last completed session was Friday, 2026-10-09. That Friday session was a normal trading day (prices exist for it).

Therefore all performance figures below refer to the session of Friday, 2026-10-09 — NOT to "today" (Sunday 2026-10-11).

2. Major index levels and returns — Friday 2026-10-09

Source: finance_data action=quote (source=yahoo) and action=analyze. For ^GSPC the analyze run (symbol "SPX", TVC) and the quote agree exactly on the close (7,811.54), confirming internal consistency.

Index	Close (2026-10-09)	1-day %	5-day %	20-day %
S&P 500 (^GSPC)	7,811.54	+0.595%	+1.15%	+2.019%
Dow Jones Industrial Avg (^DJI)	51,654.95	+0.826%	not fetched	not fetched
Nasdaq Composite (^IXIC)	27,366.17	+0.636%	not fetched	not fetched
Russell 2000 (^RUT)	2,806.98	+0.460%	not fetched	not fetched

^GSPC 5d/20d from finance_data analyze (SPX): 5d +1.15%, 20d +2.019%; RSI-14 59.8; 52-wk range position 93.8% (range 7,313.92–7,844.52). Last bar 2026-10-09.
Index-ETF proxies (fetched, offered only because the index analyze calls failed): Dow-tracking DIA 516.11, 1d +0.872%, 5d +0.98%, 20d −1.841%; Nasdaq-100-tracking QQQ 751.27, 1d +0.494%, 5d +0.225%, 20d +5.09%. These are ETFs, not the indices — do not read them as ^DJI/^IXIC figures.

The session was a broad, modestly positive day led by the Dow, with the S&P 500 closing near a record high. This is corroborated by dated search results: WSJ "Stock Market News, Oct. 9, 2026: Stocks Rise as Tech Shakes Off…" (Dow +423 pts / +0.8%; S&P 500 and Nasdaq +0.6%, https://www.wsj.com/livecoverage/stock-market-today-dow-sp-500-nasdaq-10-09-2026); AP News "How major US stock indexes fared Friday 10/9/2026" (S&P 500 +0.6% near an all-time high set three days earlier; Dow +0.8%; Nasdaq +0.6%, https://apnews.com/article/wall-street-stocks-dow-nasdaq-dafbd0c4037ee10e2a9e305f3cfa8e70).

Round 0 · Finding 4

US Equity Market Wrap — Reference Session: Friday, 2026-10-09

1. Executive Summary

Trading-date determination (required first step): Today's date is 2026-10-11. No finance_data series returned a bar for 2026-10-11. Every series I pulled (SPY, DIA, QQQ, IWM, DJI, RUT, NDX, ONEQ, TLT, IEF, and the volatility gauges) reports last_bar = "2026-10-09 13:30:00" — i.e., the most recent completed US session in the data is Friday, 2026-10-09. Consistent with that, the top organic search results for the session are dated Oct 9, 2026 ("Stock Market News, Oct. 9, 2026", "How major US stock indexes fared Friday 10/9/2026"). I therefore treat 2026-10-09 as the reference session and treat 2026-10-10/2026-10-11 as non-sessions. ⚠️ Caveat: I could not fetch an exchange calendar page to formally confirm the weekend/holiday status (see Could-Not-Fetch note); the open/closed conclusion rests on the data series terminating at 10-09.

Headline: The 2026-10-09 session was a broad up-day with tech-led recovery from a Thursday selloff. Among my tool-pulled proxies: S&P 500 ETF SPY +0.60%, Dow DJI +0.83%, Russell 2000 RUT +0.46%, Nasdaq-100 NDX +0.51%. Volatility gauges were down (VIX9D −7.8%, VIX3M −1.7%).

⚠️ Major gaps: I could not pull the actual S&P 500 and Nasdaq Composite index levels, the VIX level, or the 10-year Treasury yield from the finance tools (all caret-index and yield symbols failed). I could not fetch any in-window (10-09→10-11) news page — AP News was bot-blocked and finance_news returned zero headlines (upstream HTTP 429). Consequently catalyst attribution is NOT verified and is reported only as clearly-labeled, unfetched search snippets.

2. Key Findings (with confidence levels)

A. Index performance — reference session 2026-10-09

(Source: finance_data action=analyze, interval=1d; last_bar 2026-10-09 13:30:00)

Dow Jones Industrial Average	DJI (exchange DJ)	51,654.95	+0.826%	+0.934%	−1.747%	47.96	downtrend
Russell 2000	RUT (CBOE)	2,806.98	+0.460%	−0.915%	−3.339%	38.22	downtrend
Nasdaq-100 (proxy for growth)	NDX	30,883.15	+0.512%	+0.244%	+5.158%	60.89	strong_uptrend
S&P 500	NOT FETCHED — proxy SPY only	SPY 778.57	SPY +0.60%	+1.16%	+1.868%	59.89	strong_uptrend
Nasdaq Composite	NOT FETCHED — proxy ONEQ only	ONEQ 107.81	ONEQ +0.635%	+0.654%	+3.883%	60.20	strong_uptrend

Confidence: High that the session was up and that the Dow closed at 51,654.95 (+0.83%) and Russell 2000 at 2,806.98 (+0.46%) — these are direct index pulls. Confidence: Low on the S&P 500 / Nasdaq Composite index levels — only ETF proxies were obtainable (flagged below).

US Equity Market Wrap — Reference Session: Friday, October 9, 2026

1. Date & market-status determination (required first)

2026-10-11 was a SUNDAY — US markets were CLOSED (weekend). The last completed trading session was Friday, October 9, 2026. (Source: WhenDoesMarketOpen — "The US stock market is closed on Saturday, October 10, 2026. Reason: Weekend. Next open: Monday, October 12 at 9:30 AM ET." — https://whendoesmarketopen.com/us-stock-market/October-10-2026; and WhenDoMarketsOpen October-2026 day-by-day calendar, which lists exactly seven October sessions — Oct 1, 2, 5, 6, 7, 8, 9 — confirming Oct 10–11 as the weekend: https://www.whendomarketsopen.com/market-history/2026-10/)
Every performance figure below therefore refers to the Friday, October 9, 2026 session, which is inside the 2026-10-09→2026-10-11 window.

2. Major index levels & daily returns — reference session Oct 9, 2026

All levels/% changes below are from the finance_data (action=analyze) tool, whose last bar is timestamped 2026-10-09:

Index	Tool symbol	Close	1-day %	5-day %	20-day %	RSI-14	Trend
S&P 500	SPX (CBOE)	7,811.54	+0.595%	+1.15%	+2.02%	59.9	strong_uptrend
Dow Jones Industrial Avg	DJI (TVC)	51,660.18	+0.826%	+0.934%	−1.75%	48.0	downtrend
Nasdaq Composite	IXIC (NASDAQ)	27,366.17	+0.636%	+0.645%	+3.92%	60.3	strong_uptrend
Russell 2000	RUT (CBOE)	2,806.98	+0.46%	−0.915%	−3.34%	38.2	downtrend

Cross-check (independent, dated pages): Dean Financials "Market Pulse · Oct 9, 2026" (published 2026-10-09T20:00Z) reports S&P 7,811.54 +0.59% (+46.18), Dow 51,654.95 +0.83% (+423.31), Nasdaq 27,366.17 +0.64% (+172.83), Russell 2000 2,806.98 +0.46% (+12.85) — https://deanfi.com/insights/marketpulse/2026-10-09/ ; and Portfolio Terminal (published 2026-10-10T09:00Z) gives the same closes — https://www.portfolio-terminal.com/blog/stock-market-week-in-review-october-9-2026. Note / flag: the tool's Dow feed (TVC) prints 51,660.18 while both cash-index sources print 51,654.95 — a ~5-point feed discrepancy. Both are reported here rather than reconciled.

3. Volatility & rates (reference session)

VIX: 14.84, −3.70% on the day (−3.07% 5-day, −6.31% 20-day; RSI 45.4; 52-wk range 13.38–35.30, sitting in the bottom 6.7% of its range) — finance_data analyze, symbol VIX (CBOE), last bar 2026-10-09. Confirmed at 14.84 by Dean Financials (2026-10-09T20:00Z).
10-year Treasury yield: 5.242%, +0.134% on the day — finance_data analyze, symbol US10Y (TVC), last bar 2026-10-08T23:00 UTC. (^TNX and TNX returned no data on any exchange — see §7.) This matches independent sources: WhenDoMarketsOpen lists the Oct 9 10-yr yield at 5.24% (+2 bp) (https://www.whendomarketsopen.com/market-history/2026-10/), and Portfolio Terminal states the 10-yr "ended the week at 5.244% on October 9."

Round 0 · Finding 6

US Equity Market Wrap — Reference Session: Friday, October 9, 2026

1. Executive Summary

US equity markets were CLOSED on 2026-10-11 — that date is a Sunday (weekend). The most recent completed session is Friday, 2026-10-09. This is confirmed by the data itself: every instrument I pulled from finance_data carries a last daily bar of 2026-10-09 13:30 UTC and none carries a 10-10 or 10-11 bar, and the only 2026-10-11 news on the wire is weekend geopolitical copy (no session prints). (Note: I could not reach an official NYSE/Nasdaq holiday calendar to independently confirm the weekend status; the "closed" call is inferred from the absence of any 10-10/10-11 bars across all 19 tickers I fetched plus a "on Sunday" timestamp in the wire — treat the weekend status as high-confidence but not calendar-verified.)

Friday, Oct 9, 2026 was a broadly positive, record-adjacent session: all four major indices closed green, the S&P 500 finished 0.09% under its Oct 6 record close, and the day's defining event was a SpaceX/Starlink spectrum deal that crushed the three major US carriers and lifted the tower REITs. The single biggest whole-market gainer was micro-cap WF Holding (WFF), +499.5%.

Investigation Trail

Round 0

Was the US stock market open on Sunday 2026-10-11, and if closed, what were the official closing levels and single-day % changes on the most recent completed session (expected Friday 2026-10-09) for the S&P 500 (^GSPC), Dow Jones Industrial Average (^DJI), Nasdaq Composite (^IXIC), and Russell 2000 (^RUT)? Pull each index with finance_data action=analyze and report the close, 1-day %, 5-day %, and 20-day %.
What were the biggest individual stock movers in the US market on the most recent completed session (2026-10-09, or 2026-10-11 if markets traded) — specifically the largest S&P 500 / Nasdaq-100 gainers and losers by 1-day % change, with each ticker's price and daily % change pulled from finance_data? Include any notable single-name moves over 10% in either direction.
What specific news catalysts drove US equity market action on 2026-10-09 through 2026-10-11 — including per-ticker headlines for the session's largest movers and any macro headlines published in that window? Use finance_news (macro + per-ticker) and report the headline text, publisher, and publication timestamp for each catalyst.
Which US economic data releases, Federal Reserve communications, or policy events occurred on 2026-10-09 through 2026-10-11 (e.g. CPI/PPI, jobs report, FOMC minutes or speaker remarks, government shutdown or tariff developments), and what did markets price in as a result? Report release dates, headline numbers versus consensus where available, and market reaction.
What were the sector and breadth characteristics of the most recent completed US session (2026-10-09, or 2026-10-11 if markets traded) — performance of the 11 S&P sector SPDRs (XLK, XLF, XLE, XLV, XLI, XLY, XLP, XLU, XLB, XLRE, XLC), the VIX level, the 10-year Treasury yield (^TNX), and whether the advance/decline and equal-weight (RSP) versus cap-weight (SPY) spread signaled narrow or broad participation? Pull each with finance_data.
What forward-looking signals emerged on 2026-10-09 through 2026-10-11 for the next US session — index futures direction, notable analyst upgrades/downgrades with price targets on the session's movers, and any corporate insider (SEC Form 4) buying or selling in those movers reported in that window via finance_insider?
