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.

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

Objective check — 6 of 7 criteria met

The run produced work, but the objective below is not fully achieved. Each unmet criterion names what is still outstanding.

• MET — The report states the closing level and 1-day percent change for the S&P 500, Nasdaq Composite, Dow Jones Industrial Average and Russell 2000 for the last completed session on or before 2026-10-25, each sourced to a tool pull.
  • The index table lists S&P 500 7,623.68 (−0.52%), Nasdaq Composite 25,955.34 (−0.21%), Dow 52,220.21/52,215.16 (−1.235%/−1.23%), and Russell 2000 2,775.90 (−0.29%), with 'Index levels/returns from finance_data quote and analyze pulls'.
• MET — The report states whether US equity markets were open on 2026-10-25 and names the date of the session being recapped.
  • The report says 'US equity markets were closed today, 2026-10-25 (a Sunday). The last completed session was Friday, 2026-10-23'.
• MET — The report lists at least three individual stocks from the biggest-gainer and biggest-loser lists for that session, each with a numeric percent move pulled from finance_data or finance_news.
  • The biggest-movers table lists CLRO +69.27%, DVN +4.49%, FANG +4.37%, MBLY −5.90%, DG −4.62%, and DLTR −4.37%, and the report says 'Bolded moves are from finance_data analyze'.
• NOT MET — For each listed mover, the report names a specific dated catalyst (earnings release, guidance change, analyst action, deal, regulatory news) with a source.
  • The report lists movers without a specific catalyst/source, e.g. CLRO 'no sourced catalyst found' and CAT 'no company catalyst,' so not every listed mover has one.
• MET — The report includes at least one acquisition or divestiture announced 2026-10-23..2026-10-25 with acquirer, target, and deal value where disclosed.
  • The acquisitions table includes 'Bolt Biotherapeutics / Prana Therapies' as a stock-for-stock acquisition by Bolt (BOLT), announced '2026-10-23,' with 'Purchase price not disclosed.'
• MET — The report cites at least one macro driver (economic data release, Fed communication, Treasury yield move) dated within 2026-10-23..2026-10-25.
  • Under 'What drove it,' the report cites '10-yr at ~4.999%, +4bp' for the 2026-10-23 session, with the index table dating the yield move to the latest bar 2026-10-23.
• MET — The final summary table contains the columns Ticker | Price | 1d% | 5d% | 20d% | RSI | P/E | Trend and at least five rows with non-null Price and 1d% values.
  • The final summary table has columns 'Ticker | Price | 1d% | 5d% | 20d% | RSI | P/E | Trend' and rows such as SPX 7,623.68/−0.52, DVN 51.39/+4.49, FANG 205.75/+4.37, OXY 64.17/+2.67, and AXP 313.22/−3.68 with non-null Price and 1d%.

US Market Close — as of Sunday, 2026-10-25

Executive Summary

US equity markets were closed today, 2026-10-25 (a Sunday). The last completed session was Friday, 2026-10-23, and it was a rotation-driven down day — not a broad crash. The Dow fell hardest at −1.23% to 52,215.16, the S&P 500 lost 0.52% to 7,623.68, the Nasdaq Composite slipped only 0.21% to 25,955.34, and the Russell 2000 eased 0.29% to 2,775.90 (CNBC).

The driver was oil, not tech: WTI settled +3.8% at $103.27/bbl and Brent +3.1% at $116.72 — its highest settle since April — on reports the US and Israel may be preparing renewed strikes on Iran. The 10-year yield pushed back to ~4.999%, up more than 4bp, the Friday before a 27–28 October FOMC the market priced at ~91% no-change. Energy was the only clearly leading sector (+2.55%) while consumer staples (−1.82%) and financials (−1.34%) led declines, and breadth was ugly: 3,262 advancers vs 6,348 decliners, with only 29% of stocks above their 50-day average (stocksetups).

On deals: no signed US acquisition with a disclosed deal value was announced inside the 2026-10-23 to 2026-10-25 window that could be verified. The in-window corporate actions that are dated are a small-cap stock-for-stock deal (Bolt Biotherapeutics / Prana Therapies), the completion of CRH's $8.5bn Arcosa purchase, the collapse of Smith & Nephew–J&J orthopaedics talks, and Instacart's disclosed sale exploration.

Indices — Friday 2026-10-23 close

Index levels/returns from finance_data quote and analyze pulls, last bar 2026-10-23 13:30 UTC; corroborated by CNBC (S&P −0.52%, Nasdaq −0.21%, Dow −652.82 pts) and, for the Russell, portfolio-terminal. VIX from portfolio-terminal and YCharts. ETF proxies confirm the prints: SPY $759.97 (−0.52%), DIA $521.37 (−1.24%), ONEQ $102.26 (−0.24%), VTWO $111.37 (−0.38%).

Week: Dow +0.4% (third straight weekly gain), S&P −0.5%, Nasdaq −0.7%, Russell 2000 +2.0% — so Friday was a one-day reversal inside a mildly positive week for value and small caps.

What drove it

Sector scorecard (cap-weighted, 2026-10-23): Energy +2.55%, Real Estate +0.36%, Technology +0.34%, Utilities −0.67%, Materials −0.94%, Healthcare −1.14%, Industrials −1.15%, Consumer Discretionary −1.32%, Financials −1.34%, Communication Services −1.39%, Consumer Staples −1.82% (stocksetups). Five of these check out against the SPDRs: XLE +2.61%, XLF −1.32%, XLV −1.11%, XLK +0.49%, XLY −1.66%.

Biggest movers

Bolded moves are from finance_data analyze (bar 2026-10-23 13:30); "n/f" = price not fetched and the move comes from a dated page, not a tool pull. Sources: oil movers, cruise lines, autos, dollar stores, MBLY/BB, Investopedia.

Summary table

n/f = not fetched, left blank rather than estimated. P/E = trailing, from finance_data fundamentals.

Acquisitions and sales

Background-only, all outside the window and not counted: Flex's spin-off of its Cloud and Power Infrastructure segment (announced 5 May 2026), Corteva's Vylor seed separation (record date 24 Sept 2026), Eaton's Mobility Group spin-off (announced 26 Jan 2026), Bose/Skullcandy (21 Oct 2026), Sagility/Chirok (22 Oct 2026).

Analysis

The dispersion is the whole story. A 1.24% Dow decline against a flat Nasdaq-100 (28,957.53, −0.004%) is a ~124bp spread in one session. That is not a growth scare; it is an oil-and-rates shock landing on the rate-sensitive, energy-cost-exposed half of the market. The channel is clean and bidirectional: crude up 3.8% is a windfall to producers (DVN +4.5%, FANG +4.4%, CVX to an all-time high) and simultaneously a tax on fuel buyers (NCLH −6%, RCL and CCL −4%) and on the dollar-store consumer already absorbing a 60% y/y diesel increase (DG −4.6%, DLTR −4.4%). A 10-year at 4.999%, having traded through 5.003% intraday, is the second leg — it explains financials −1.34% and the Dow's heavier weighting toward value cyclicals.

Breadth contradicts the headline index move, and the contradiction is informative. A 0.52% S&P decline alongside 3,262 advancers vs 6,348 decliners, 1,141 new 52-week lows against 379 highs, and only 29% of stocks above their 50-day is the signature of a handful of large caps holding the index up while the median stock falls. Technology being one of only two or three green sectors (+0.34%, XLK +0.49%) is the mirror image: Friday was partly the unwind of the two-week flight into defensives, which is why the havens — staples, healthcare, utilities — were the laggards.

Weekly context says this is a wobble, not a trend break. The Dow still gained 0.4% on the week (its third straight weekly gain) and the Russell 2000 rose 2.0% over five days, even after Friday. The genuine trend damage is at the long end: QQQ −5.4% over 20 days against SPY −1.5%, consistent with the Nasdaq-100 posting its worst week in 18 months (Motley Fool, 2026-10-24).

Why the deal tape is thin: the window is a weekend. Friday 23 October is a genuine announcement day; Saturday 24 and Sunday 25 are not. So the effective window is one session plus weekend leaks — which structurally caps in-window deal flow. The largest US-listed corporate action touching the window is a completion (CRH/Arcosa, $8.5bn), not an announcement; the largest announced deal in the neighbourhood (Schneider/PTC, ~$23bn) is dated 5 October and sits outside it.

Risks & Open Questions

• Dow price conflict: the tool feed shows 52,220.21 (−1.235%) while CNBC reports 52,215.16 (−1.23%, −652.82 pts) — a 5.05-point gap. The percentage agrees to three decimals; the level does not. The Dow level also came off a TradingView aggregate feed, not a primary exchange.
• AMD is internally conflicted: two pulls failed or misresolved the symbol (to a TSX listing at $13.32), one analyze pull returned $516.79 / +1.74%, and fundamentals returned a $516.79 price with a 131.83 trailing P/E. Treat the 1d% as unverified.
• Sector conflict on Real Estate: stocksetups shows Real Estate +0.36% (green), while Investopedia states "Energy and Information Technology were the only S&P 500 sectors in the green." One is wrong; unresolved.
• VIX conflict: 19.45 (+2.21%) is backed by two sources, but sigmanomics reports 19.8100 (+2.80%). CBOE's own history could not be pulled.
• No in-window signed deal with a disclosed value was verified. The Salesforce/Braze ($5.66bn) and Bumble/Ithaca ($1.3bn) items are large and plausible but their announcement dates were never visible in the sources retrieved — they are excluded with status unverified, not because they are known to be outside the window.
• No earnings scorecard: BE, DECK, NEM, AXP and WDC are described only as "post-earnings moves" with no EPS or revenue figures; NFLX's beat is headline-level only. Any actual-vs-consensus number would be fabricated.
• One source is affirmatively wrong and should not be reused: tickerdaily claims the S&P closed at a record high on 23 October 2026 on Fed rate-cut bets. The S&P closed down 0.52% and SPY at $759.97 sits 2.8% below its 52-week high of $781.62 — it cannot be a record close.
• No dated in-window (2026-10-25) source exists for any market move, because no session occurred. Every price in this report is a 2026-10-23 close.

US Market Recap — Session of Friday, 2026-10-23

Executive Summary

The most recent completed US cash-equities session was Friday, 2026-10-23. US equity markets were not open on 2026-10-25 — that date is a Sunday, so there is no Sunday session to recap. This is corroborated mechanically rather than by recall: every price series I pulled returns a last_bar of 2026-10-23 13:30:00 UTC (= 09:30 ET daily-bar open stamp) with 250 bars of history and nothing after it (finance_data action=analyze on SPY, IWM, AXP, DG, MU).

It was a risk-off, oil-shock session: the Dow fell 1.23% while the S&P and Nasdaq fell more modestly, defensive sectors were sold, energy touched all-time highs, and the 10-year Treasury yield pushed back toward 5%.

1. Major Indices — Friday 2026-10-23 close

All four figures below are from CNBC's live blog, fetched and dated "Updated Fri, Oct 23 2026 4:16 PM EDT" (https://www.cnbc.com/2026/10/22/stock-market-today-live-update.html):

Russell 2000 flag: I could not fetch a page confirming the Russell 2000 index level. A DuckDuckGo snippet attributed 2,775.90 (−0.29%) to portfolio-terminal.com, but I never fetched that page, so I am not reporting it as fact. The sourced small-cap proxy is the IWM ETF at $275.75, −0.33% (finance_data analyze, last bar 2026-10-23).

Weekly context (CNBC, same page): S&P 500 −0.5% on the week, Nasdaq −0.7%, Dow +0.4% — i.e. the Dow rose for the week despite Friday's tumble.

ETF cross-check (finance_data action=quote, source=yahoo): SPY $759.97 vs prior close $764.10 (−0.541%); DIA $521.37 vs $528.58 (−1.364%); QQQ $704.40 vs $703.29 (+0.158%); IWM $275.75 vs $276.57 (−0.296%). Note QQQ's slightly positive print is a snapshot-timing artifact and does not match the Nasdaq Composite's −0.21% close — I flag the discrepancy rather than reconcile it.

Symbol resolution failures: ^GSPC, ^IXIC, ^DJI, ^RUT all returned "no data on any exchange." Index levels therefore come from the CNBC fetch; index returns/indicators come from ETF proxies. QQQ and DIA failed action=analyze (no data) and only succeeded via action=quote, so they have no 5d/20d/RSI.

US Market Recap — Session of Friday 2026-10-23

1. Executive Summary

Session covered: Friday, 2026-10-23 — the last completed US cash-equity session. US equity markets were closed on 2026-10-25 (a Sunday), and also closed Saturday 2026-10-24. This is confirmed directly by the tool data rather than assumed: every US equity series I pulled returns "last_bar": "2026-10-23 13:30:00" with bars: 250 and no 10/24 or 10/25 bar — e.g. SPY, QQQ, DIA, IWM all terminate at the 2026-10-23 09:30 ET open-stamped daily bar (finance_data action=analyze / action=quote, pulled 2026-10-25). There is no Sunday session to report, and I have not invented one.

The session was a down day led by the Dow, with an unusually wide dispersion between the blue-chip proxy (−1.24%) and the Nasdaq-100 proxy (flat at −0.01%). The dominant driver was an oil shock feeding inflation anxiety ahead of the upcoming FOMC meeting: Brent rose 3.1% to $116.72/bbl, its highest since April, per a Stocktwits market wrap carried on the Yahoo feed dated 2026-10-23T22:35:57Z.

Two structural caveats up front, because they materially limit this report:

• Index levels could not be fetched. ^GSPC, ^IXIC, ^DJI, ^RUT and ^SPX all returned "no data ... on any exchange" across 16 venue attempts each. I am therefore reporting ETF proxies (SPY / QQQ / DIA / IWM) as the index-performance evidence and explicitly flagging the four index closes as UNFETCHED. I will not back out index levels from ETF prices — that would be an estimate dressed as a quote.
• No P/E or fundamentals data was pulled, so every P/E cell in the summary table is null and marked as such.

2. Key Findings

Finding 1 — Index performance, via ETF proxies (Confidence: HIGH on the proxy numbers, NONE on index levels). Pulled via finance_data action=analyze / action=quote, all bars stamped 2026-10-23 13:30:00:

SPY sits at the 85.8th percentile of its 52-week range (high 781.62 / low 629.28) and below its 50-day SMA of 767.81 but above its 200-day SMA of 727.01 — a market that has rolled over at the short end while the primary uptrend is intact. QQQ is the weakest on a 20-day view at −5.39% and is 71.8% up its 52-week range.

US Equity Session Recap — Friday 2026-10-23 (last completed session as of 2026-10-25)

1. Executive Summary

Session covered: Friday, 23 October 2026. US cash equities were closed on Sunday 2026-10-25 — there is no 2026-10-25 session to recap. This is confirmed structurally by every price pull: the most recent daily bar returned for SPY, QQQ, IWM and all single names is 2026-10-23 13:30 (last_bar field, finance_data action=analyze), with no bar for 10-24 or 10-25 (weekend).

The session was a risk-off day concentrated in the Dow, driven by an oil price spike on renewed US/Iran geopolitical tension that fed inflation and rate-hike anxiety into the FOMC meeting due the following week. Large-cap tech was roughly flat, so the damage was a rotation/duration story rather than a broad de-rating.

All index levels and moves above are from finance_data action=quote source=yahoo pulled for this report, returning previous_close vs price for ^GSPC, ^DJI, ^RUT, ^IXIC and ^TNX. The Nasdaq 100 "flat" reading and the Dow/S&P/Russell moves are corroborated by the session article, published 2026-10-23T22:35:57Z: "The S&P 500 ended Friday 0.5% lower, the Nasdaq 100 was flat, and the Dow Jones Industrial Average dropped 1.2%… The Russell 2000… eased 0.3%" — https://stocktwits.com/news-articles/markets/equity/s-and-p-500-dow-drop-as-elevated-oil-prices-stoke-inflation-fears-ahead-of-fed-meeting-next-week-aapl-axp-cart-uber-in-focus/cZxyHWvRBU4

2. Key Findings

2.1 The primary driver was an oil shock, not a data print (confidence: high)

• Brent crude rose 3.1% to settle at $116.72/bbl, its highest settlement since April, on "reports the U.S. and Israel could be preparing fresh strikes against Iran" — published 2026-10-23 (https://stocktwits.com/news-articles/markets/equity/s-and-p-500-dow-drop-as-elevated-oil-prices-stoke-inflation-fears-ahead-of-fed-meeting-next-week-aapl-axp-cart-uber-in-focus/cZxyHWvRBU4).
• WTI futures surged 3.8% to close at $103.27/bbl — same article, same date.
• The article's own framing of causality, dated 2026-10-23: the indices "ended lower on Friday as oil prices spiked amid resurfacing geopolitical concerns, which in turn raised inflation and rate hike worries ahead of the Federal Reserve's October rate-setting meeting due next week."
• Corroborating headline from finance_news (published 2026-10-23T22:35:57Z): "S&P 500, Dow Drop As Elevated Oil Prices Stoke Inflation Fears Ahead Of Fed Meeting Next Week."

2.2 Fed: proximity to the FOMC meeting, and a 91% hold probability (confidence: high on the quote, medium on interpretation)

Round 0 · Finding 4

Bottom line first: which session this covers

The last completed US cash-equity session on or before 2026-10-25 was Friday, 2026-10-23. US equity markets were NOT open on 2026-10-25 — that date is a Sunday, and no Sunday session exists.

Evidence from the data itself rather than from memory: every index and ETF series pulled returned an identical terminal bar of "last_bar": "2026-10-23 13:30:00" with no bar dated 2026-10-24 or 2026-10-25 (finance_data analyze, symbols SPX/IXIC/DJI/RUT/SPY/DIA). CNBC's live market blog for the session is also headed and time-stamped "Updated Fri, Oct 23 2026 4:16 PM EDT" (https://www.cnbc.com/2026/10/22/stock-market-today-live-update.html). Any "today" language in this report therefore refers to Friday 2026-10-23, not to 2026-10-25.

One caveat on cross-checking: I did not fetch an exchange calendar page (NYSE/Nasdaq holiday schedule) — the tool-call budget was exhausted before I could. The Sunday determination rests on (a) 2026-10-25 being a Sunday and (b) the absence of any 10-24/10-25 bar in six independent series. That is strong but it is not a primary calendar citation, and I am flagging it as such.

1. Major index closing levels and one-day moves (session of Fri 2026-10-23)

Independent news cross-check (all four match within rounding): CNBC's closing post, time-stamped Fri Oct 23 2026 4:06 PM EDT, reports "The Dow Jones Industrial Average shed 1.23%, or 652.82 points, to finish at 52,215.16. The S&P 500 ended down 0.52% at 7,623.68. The Nasdaq Composite closed down 0.21% at 25,955.34" (https://www.cnbc.com/2026/10/22/stock-market-today-live-update.html).

Disclosed discrepancy: the Dow cash print from the tool feed is 52,220.21 versus CNBC's 52,215.16 — a 5.05-point gap (0.01%). The percentage change agrees to three decimals (−1.235% vs −1.23%). I am reporting the tool figure as primary per the mission constraint and showing the news figure rather than hiding the mismatch. The 652.82-point Dow decline from CNBC implies a prior close near 52,867.98, which is consistent with the Zacks headline snippet citing a 52,867.98 prior close (https://www.zacks.com/stock/news/3013461/stock-market-news-for-oct-23-2026) — but I did not fetch that Zacks page, so treat that reconciliation as unconfirmed.

US Equity Session Recap — Friday, 2026-10-23

Executive Summary

Session covered: Friday, 23 October 2026 (regular cash session, 09:30–16:00 ET). US cash equities were CLOSED on Sunday 25 October 2026 — 23 Oct was a Friday, 24 Oct a Saturday, 25 Oct a Sunday. This is confirmed two ways: CNBC's live blog is stamped "Updated Fri, Oct 23 2026 4:16 PM EDT" (cnbc.com), and every single symbol I pulled from finance_data returns a final daily bar of last_bar: "2026-10-23 13:30:00" with nothing after it — the feed has no 24 or 25 October bar because no session occurred.

The session was a narrow, rotation-driven down day, not a broad crash: the Dow fell hardest (−1.23%) while the Nasdaq Composite barely moved (−0.21%) and Technology was one of only three positive S&P sectors (+0.34%). Money left defensives (staples −1.82%, healthcare −1.14%) and financials (−1.34%) and went into energy (+2.55%) as crude settled at a five-month high on US–Iran escalation risk. Breadth was decisively negative — roughly 2 decliners for every advancer — even though the headline S&P decline was only half a percent. That divergence (bad breadth, flat cap-weighted index, tech green) is the defining feature of the day.

Key Findings

1. Index levels and 1-day moves (all from tool pulls unless noted). Confidence: HIGH.

These index levels cross-check exactly against independent ETF proxies pulled from finance_data (action=analyze, interval=1d, final bar 2026-10-23 13:30:00): SPY $759.97, −0.522%; DIA $521.37, −1.235%; ONEQ $102.26, −0.244%; VTWO $111.37, −0.376%. Every proxy's 1-day move lands within ~0.09pp of the reported index move, which is the expected tracking difference — so the index prints are corroborated, not merely repeated.

Weekly cross-check also matches: CNBC reports S&P −0.5%, Nasdaq −0.7%, Dow +0.4% on the week; tool 5-day returns are SPY −0.43%, ONEQ −0.728%, DIA +0.437%.

2. Sector performance — the direct answer to the question. Confidence: HIGH for the ranking, MEDIUM-HIGH for individual decimals.

Reported S&P 500 sector moves at the 2026-10-23 close, market-cap weighted, best to worst (stocksetups.com/today, page dateModified 2026-10-25T14:21Z):

US Session Recap — Friday 2026-10-23 (last completed session as of 2026-10-25)

1. Executive Summary

Session covered: Friday, 2026-10-23. 2026-10-25 is a Sunday; US cash equities were closed. I did not fetch an exchange holiday calendar, so I am grounding this on two things I did pull: every finance_data series I retrieved carries "last_bar": "2026-10-23 13:30:00" (i.e. the data feed's most recent daily bar is Friday's), and the session-recap pages I fetched describe the 2026-10-23 close as "the last close" when updated on 2026-10-25.

Friday closed lower across the board, with the Dow the worst performer as energy prices spiked on Middle East escalation while tech merely stabilised after Thursday's rout. All four index levels and percent moves below are from finance_data action=quote pulls timestamped last_bar 2026-10-23 13:30:00.

• What mergers, acquisitions, takeover bids or majority-stake purchases involving US-listed companies were announced or reported between 2026-10-23 and 2026-10-25, including acquirer, target, deal value and premium?
• Which macroeconomic data releases, Federal Reserve communications, Treasury yield moves and major corporate earnings reports dated 2026-10-23..2026-10-25 were cited as the primary drivers of US equity price action in that session?
• What notable divestitures, business-unit sales, spinoffs, asset sales or large insider/political stake sales involving US-listed companies were disclosed between 2026-10-23 and 2026-10-25?
