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 Saturday 2026-09-26, there was no US stock market session today — NYSE and Nasdaq were closed, so the market did not "perform" today. The last completed session was Friday 2026-09-25, and it closed up across every major index: S&P 500 7,743.41 (+0.51%), Dow Jones Industrial Average 51,828.62 (+0.93%), Nasdaq Composite 27,068.72 (+0.48%), Nasdaq-100 30,608.13 (+0.42%), Russell 2000 2,837.55 (+0.07%). It was a large-cap/tech-led advance — nine of eleven S&P sectors were green, but the Russell 2000 was effectively flat and the Dow is still −3.25% over 20 days, so the breadth under the surface was thin.

The biggest movers were micro-caps, not index members (MSGY +309.6%, IPEX −57.8% on the day). Among mega-caps, the largest verified moves were MSFT +3.66% and META −3.34%. The drivers were Brent crude falling below $98/bbl, Treasury yields slipping, and AI/mega-cap leadership, plus single-name catalysts (Akamai's $11.6B Anthropic deal, HSBC's Synopsys upgrade, BofA's Nike downgrade). Every figure below is labeled with the session it belongs to; 2026-09-26 itself produced only weekend news-wire flow (Trump–Xi AI talks, Iran, oil-supply strikes), which sets up Monday 2026-09-28.

Major Indices — Friday 2026-09-25 Close

Index and ETF rows from finance_data action=analyze, daily bars, last bar 2026-09-25, corroborated by the fetched CNBC Sept 25 live blog (cnbc.com) and AP (apnews.com). Weekly context: Dow +0.3%, S&P 500 +1.2%, Nasdaq +2.0% — the S&P's first winning week in three. No P/E was fetched for any index row; the cell is marked, not estimated.

Sector tape (SPDR ETFs, 2026-09-25): XLI +0.95% and XLK +0.80% led; the only decliners were XLE −0.90% and XLC −0.90%. Note the divergence: XLK sits at RSI 65.4 / strong_uptrend while XLU (RSI 24.1), XLRE (24.1) and XLF (32.9) are in downtrends at the bottom of their ranges — the index gain was narrow at the leadership level.

Biggest Movers — Friday 2026-09-25

Market-wide (tool-verified via finance_data; corroborated by a same-day aggregator with small vendor differences):

None of these are S&P 500 or Nasdaq-100 constituents. They are $1–$8 micro-caps with collapsed 52-week ranges (MSGY sits at 3.8% of its range, INLF at 0.1%) — speculative one-day spikes, not a market-wide signal. A second aggregator's same-session list is directionally identical (MSGY +311.68%, IPEX −55.88%, INLF +73.90%) (stocksetups.com/movers/today); the small differences are vendor noise.

Index-member movers (the names that actually moved the tape):

MSFT's +3.66% is consistent with the dated recap describing Microsoft closing "at its highest price of 2026" on enterprise-AI monetization (tradingstrategyguides.com, Sep 25 2026). META's −3.34% is a pullback from a +31.6% 20-day run with RSI still at 71.3. NKE sits at just 1.3% of its 250-session range.

Premarket-only moves — these are NOT closing moves. Per CNBC's Sept 25 premarket page (cnbc.com): AKAM jumped over 21% premarket on a seven-year power contract and an $11.6B deal with Anthropic (warrant for ~5% of Akamai at $111.33); SCHL slid over 10% on an FQ1 adjusted loss of $3.63/share vs $2.52 a year earlier, revenue $216.8M (−4% y/y); SNPS gained over 3% on an HSBC upgrade but faded to +0.20% at the close (tool-verified); NKE slid nearly 2% on a BofA downgrade to underperform; COST fell slightly despite beating ($6.60 adj EPS vs $6.53 est; $95.72B revenue vs $94.86B est).

What Drove It

In-window (2026-09-26) catalysts — weekend wire only, no same-day market reaction: Trump said he "had a major discussion on artificial intelligence with China's Xi" (FinancialJuice, 13:50Z); Trump rejected Iran's proposal (13:47Z); fresh oil-supply risk from Libya's halted Zawiya refining unit and Ukraine's strike on the Ilsky refinery; and a week-ahead calendar flagging US inflation data and non-farm payrolls as the coming week's events (16:48Z).

Analysis

The single most important fact is structural: 2026-09-26 was a Saturday, confirmed by every series returning a last bar of 2026-09-25 and by the SPY bar series skipping the Monday 2026-09-07 Labor Day holiday. Anyone quoting "today's" index levels for 9/26 is quoting Friday's tape.

The Friday session was up but internally weak. Nasdaq-100 sits at the 98th percentile of its 52-week range with RSI 64.7, while the Russell 2000 is at the 69.7th percentile with RSI 34.9 and −5.87% over 20 days. That is a market where mega-cap growth is doing all the work: the Dow is in a 20-day drawdown (−3.25%) and QQQ is +3.24% over the same window. Volatility confirms the complacent regime — VIX 14.87 (−5.11%), at 6.8% of its 52-week range, with VIX3M at 17.93 sitting above spot VIX, an upward-sloping term structure pricing no near-term stress.

Attribution is straightforward and internally consistent: oil below $98/bbl and slipping yields lifted a broad tape while pressuring energy (−0.90%), and AI-linked mega-cap tech supplied the leadership. The micro-cap movers (+300%, −58%) are noise, not signal; there is no dated in-window source tying them to a driver.

Risks & Open Questions

• Dow level has mixed provenance. The fetched CNBC page gives 51,828.62; the finance_data DJI series printed 51,834.17 (+0.933%), and one batch returned a DJI series byte-identical to IXIC. Direction (+0.93%) is solid across AP, CNBC and the tool; the exact close differs by ~0.01%.
• Large-cap fetches were inconsistent across calls. NVDA and MU returned data in one batch and "no data" in another; AMZN, GOOGL, AVGO, AMD, INTC, ORCL, PLTR and COIN failed outright. Those names are flagged unavailable, not estimated.
• AKAM, SCHL, NKE and COST moves are premarket figures from a single CNBC page, not verified closing moves. AKAM's ~21% was never confirmed at the close.
• Breadth is snippet-sourced. The 328-up/173-down S&P 500 readout and the +352 net-advance figure come from search snippets whose page bodies did not render; treat as indicative.
• No dated in-window (2026-09-26) driver exists for an equity move, because none occurred. As of this report, the September NFP, August PCE and JOLTS prints had not been released — any actual-vs-consensus comparison would be fabricated.

Detailed Findings

US Equity Market Recap — request dated 2026-09-26

⚠️ Session-identity correction (read first)

2026-09-26 was a Saturday. There was no US cash-equity session that day. I verified the weekday directly with a tool call rather than from memory: a browser eval of new Date('2026-09-26T12:00:00Z').getUTCDay() returned 6 and the string "Sat, 26 Sep 2026". Every market series I pulled independently confirms this — the last bar for all four index proxies and all four ETFs is stamped 2026-09-25 13:30:00 (i.e., Friday's session open), with nothing dated 9/26.

Accordingly, everything quantitative below describes the Friday 2026-09-25 session — the most recent completed session — and is labelled as such. I did not re-label it as "today's" performance. The 2026-09-26 material in this report is Saturday news-wire and week-ahead content only, which sets up Monday 2026-09-28; it is not a session recap and I do not treat it as one.

1. Findings — index closes and 1-day changes (session: Fri 2026-09-25)

All figures from finance_data action=analyze, interval=1d, 250 bars; last_bar = 2026-09-25 for every symbol.

Verdict: a uniformly UP but narrow session — the "up" was carried by large-cap tech; the Russell 2000's +0.07% is effectively flat, and the Dow's +0.933% merely recovers part of a weak month (20-day −3.248%).

Intraday range (open/high/low/close) for the index proxies

The caret symbols the request suggested (^GSPC, ^DJI, ^IXIC, ^RUT) all failed — finance_data returned no data for ^GSPC on any exchange (same for ^DJI, ^IXIC, ^RUT, and also for US500, US2000, ES1!, NQ1!). A realtime action=quote source=pyth attempt also failed (no Pyth feed for symbol; SPY/DIA/QQQ/IWM returned hermes: HTTP Error 401: Unauthorized). I substituted the exchange-listed ETF proxies, which returned full OHLC:

Index-level OHLC that did come back:

• DJI 2026-09-25: O 51,365.136 / H 51,880.1875 / L 51,344.1339 / C 51,834.1729
• IXIC 2026-09-25: O 26,970.9517 / H 27,122.7633 / L 26,876.2715 / C 27,068.7165
• RUT 2026-09-25: O 2,839.221969 / H 2,851.697615 / L 2,826.792803 / C 2,837.552217

US Equity Market — Session Recap for 2026-09-26 (and the date problem)

Executive Summary

There was no US equity trading session on 2026-09-26. The date falls on a Saturday, so US cash equities, Cboe volatility indices, and US index futures were all closed. Every series I pulled from the finance tools confirms this: the last daily bar for SPY, QQQ, DIA, IWM, VIX, VIX3M and VIXY is 2026-09-25, with no 2026-09-26 bar existing for any of them (finance_data analyze/history, finance_data tool).

I therefore report the most recent completed session — Friday, 2026-09-25 — explicitly labelled as such, plus news actually published on 2026-09-26 (the weekend window). Per the anti-goals, I am not presenting 9/25 as "today's" performance, and I am not inferring any move from headlines: every level and percentage below is from a tool call or a page I fetched.

Confidence that 2026-09-26 is a Saturday / no session occurred: high (~0.9) — see verification below.

1. Date verification (why there is no 2026-09-26 session)

Two independent structural checks inside the pulled data fix the calendar:

• The daily bar series for SPY runs 2026-09-21, 09-22, 09-23, 09-24, 09-25 and stops. No bar exists for 09-26 or 09-27 (finance_data history, SPY OHLCV). If 09-25 were a Thursday, a Friday 09-26 bar would exist. It does not.
• The series omits 2026-09-07 (SPY/QQQ jump from 2026-09-04 straight to 2026-09-08), i.e. the Monday Labor Day holiday. Labor Day 2026 is the first Monday of September = Sept 7, which places Sept 12/13, 19/20 and 26/27 as weekends.

I attempted an independent calendar confirmation at timeanddate.com, which was blocked by bot protection (browser fetch → domain_blocked:www.timeanddate.com), so the Saturday conclusion rests on the trading-calendar structure embedded in the pulled bars, not on a fetched calendar page.

2. Major index closes — Friday 2026-09-25 (most recent session)

From a CNBC live-blog page I fetched (page header: "Updated Fri, Sep 25 2026 6:41 PM EDT", title "Stock market news for Sept. 25, 2026", https://www.cnbc.com/2026/09/24/stock-market-today-live-updates.html):

Weekly context (same fetched CNBC page): for the week ending 9/25 the Dow rose 0.3%, the S&P 500 +1.2%, the Nasdaq +2.0% — the S&P's first winning week in three (corroborated by AP snippet: "closed out their first winning week in the last three," https://apnews.com/article/wall-street-stocks-dow-nasdaq-36d06c7a598e03539e0e09bdf6b7ede2).

Round 0 · Finding 3

US Equity Market Recap — requested for 2026-09-26

⚠️ Headline finding: there was no 2026-09-26 US equity session

2026-09-26 is a Saturday. US equity markets (NYSE/Nasdaq) do not trade on Saturdays, so the premise of a "2026-09-26 session" cannot be satisfied. I am not going to relabel another day's tape as "today's."

Evidence (two independent legs):

1. Calendar: 2026-09-26 falls on a Saturday — confirmed by browser search_engine_results for "September 26 2026 day of week Saturday", returning e.g. "September 26, 2026 is a Saturday — it's week 39 of 2026 and day 269 of the year" (howlongagogo.com) and "September 26, 2026 is a Saturday" (whattheday.com).
2. Price feed: every finance_data call I made returns "last_bar": "2026-09-25 13:30:00" — i.e. the most recent completed daily bar is Friday, 2026-09-25. There is no 2026-09-26 bar for SPY, SPX, DJI, NDX, QQQ, DIA, IWM, NYA or TLT. (Tool: finance_data action=analyze/quote/history; e.g. SPY history showed the last 30 daily bars ending 2026-09-25, with 2026-09-25 as the final ohlcv row: O 768.78 / H 772.28 / L 766.29 / C 771.35.)

Consequently, none of the mission's success criteria can be met for the date 2026-09-26 — not index closes, not movers, not drivers. What follows is (a) the most recent completed session, Friday 2026-09-25, explicitly labeled as such, and (b) the headlines that genuinely carry a 2026-09-26 dateline (weekend geopolitical/macro wire items), which are real but did not move any US cash session because none was open.

Executive Summary

• The last US cash session was Friday, 2026-09-25, and it was up across the board: S&P 500 7,743.41 (+0.51%), Dow Jones Industrial Average 51,828.62 (+0.93%), Nasdaq-100 30,608.13 (+0.42%). Small caps lagged: iShares Russell 2000 ETF 281.97 (+0.11%). (All from finance_data action=analyze, last bar 2026-09-25.)
• On 2026-09-26 (Saturday) the equity tape was closed. In-window news flow was therefore weekend macro/geopolitical wire — US–China AI/Taiwan readouts, a rejected Iranian proposal, Cuba normalization talk, Libya/Russia/Ukraine energy-infrastructure strikes — none of which can be tied to a same-day index move because there was no same-day index move.
• Explicitly unavailable: Nasdaq Composite (^IXIC, and COMP mis-resolved to Compass Inc. at $9.38), Russell 2000 index (^RUT), VIX (^VIX), US 10-yr yield (^TNX), and equity-index futures (ES=F, NQ=F, RTY=F). No P/E was fetchable for any index row. I did not estimate any of these.

Round 0 · Finding 4

US Equities — Session Recap for 2026-09-26

⚠️ Date-critical finding first: there was no 2026-09-26 US trading session

2026-09-26 is a Saturday. I verified this directly rather than assuming it: a browser eval on the live tab returned dow: 6, dowName: "Sat, 26 Sep 2026 12:00:00 GMT", and a system clock of "Sat, 26 Sep 2026 17:09:33 GMT". Every finance-tool series I pulled independently confirms it — all of them carry last_bar: "2026-09-25 13:30:00" (source: finance_data action=analyze for XLK, XLV, XLI, XLB, XLU, XLRE, XLC, XLF, XLE, XLY, XLP, SPX, DJI, IXIC, RUT, NDX, QQQ, SPY, IWM, DIA).

NYSE/Nasdaq were closed on 2026-09-26. The most recent completed session is Friday, 2026-09-25, and that is what this recap describes — explicitly labeled as Friday's session, not "today's." Presenting 2026-09-25 data as a 2026-09-26 session would be exactly the error this task's anti-goals prohibit.

1. Executive Summary

• There was no 2026-09-26 session — it is a Saturday. The last completed US session was Friday, 2026-09-25, a broadly up day: S&P 500 7,743.42 (+0.51%), Nasdaq Composite 27,068.72 (+0.48%), Russell 2000 2,837.55 (+0.07%). The Dow's index level could not be reliably retrieved (see flag in §4); AP reported the Dow rose 0.9% Friday.
• Sector leadership on 2026-09-25 was Industrials-led, tech-supported; Energy and Communication Services lagged. XLI +0.95% and XLK +0.80% led; XLC −0.90% and XLE −0.90% were the two decliners at the bottom, with XLRE −0.22% the only other negative.
• The clearest rotation signal: energy was a laggard while Brent crude fell below $98/bbl (AP, 2026-09-25) — i.e., the index gain was not commodity-led. Leadership instead came from large-cap tech/software (Microsoft hit a 2026 high) and industrials.
• Russell 2000 diverged: +0.07% on the day and −0.80% on the week (RUT 5-day −0.799%), versus NDX +3.25% on the week — a mega-cap-over-small-cap week.
• Gap flagged, not filled: I could not verify specific 1-day percentage moves for individual stock gainers/losers. The finance tools exposed no screener, and the movers pages surfaced in search were not fetched (tool budget exhausted). The only named single-stock items I can cite are qualitative.

2. Sector-Level Performance — the core answer (session of Friday 2026-09-25)

All 11 SPDR sector ETFs were pulled in a single finance_data action=analyze call (batched: XLK/XLV/XLI/XLB/XLU/XLRE/XLC in one call; XLF/XLE/XLY/XLP in another). Values are the tool's change_pct_1 for the 2026-09-25 bar.

Round 0 · Finding 5

US Equity Market Recap — Friday, 2026-09-25 Session

(Requested as "today, 2026-09-26" — see critical date correction below)

0. CRITICAL DATE CORRECTION (read first)

2026-09-26 is a Saturday. There was no US equity session on 2026-09-26. The most recent (and only adjacent) session was Friday, 2026-09-25.

Evidence:

• Every instrument I pulled from finance_data returned last_bar: "2026-09-25 13:30:00" — for SPX, DJI, IXIC, NDX, RUT, SPY, DIA, IWM and ~60 single stocks. There is no 2026-09-26 bar.
• A dated session recap states: "In the Friday, September 25, 2026 session (closing bell at 4:00 p.m. New York time)" — https://quant500.com/sp500-gainers-losers (page titled "S&P 500 Top Gainers and Losers, Sep 25, 2026").
• A market-movers page stamps itself "Session close · 4:00 PM ET · Sep 25, 2026" — https://stocksetups.com/movers/today
• A dated "Closing Bell" column is headed "Closing Bell September 25, 2026" — https://tradingstrategyguides.com/closing-bell-september-25-2026-microsoft-surges-tesla-sinks/

Consequence for this report: I am reporting the Friday 2026-09-25 session, explicitly labeled as such. I am NOT presenting it as "today's 2026-09-26 session," because no such session exists. The only 2026-09-26-dated material is weekend geopolitical news (FinancialJuice, cited below). This is exactly the anti-goal the brief warns about, so I am flagging it rather than papering over it.

1. Executive Summary

• The last US session (Fri 2026-09-25) closed mixed-to-higher with a mega-cap tech skew: the S&P 500 rose 0.51% to 7,743.41, the Nasdaq Composite +0.48% to 27,068.72, the Nasdaq-100 +0.42% to 30,608.13, and the Dow +0.93% to 51,834.17, while the Russell 2000 was flat (+0.07% to 2,837.55). (finance_data analyze, last bar 2026-09-25)
• Breadth was positive but not euphoric: 328 of 503 S&P 500 tickers rose, 173 fell, 2 unchanged (https://quant500.com/sp500-gainers-losers).
• The largest percentage movers market-wide were small/micro-caps, not index members. Top gainer MSGY +311.68%; top decliner IPEX −55.88% (https://stocksetups.com/movers/today).
• Mega-cap standouts I could verify with live data: MSFT +3.66% (biggest mega-cap gainer I fetched) and META −3.34% (biggest mega-cap decliner I fetched), with TSLA −1.54% and AAPL +1.53% (finance_data).
• Drivers are only partially verifiable. I could confirm dated headlines (US–China AI/Taiwan talks, Iran, Libya pipeline, Ukraine refinery strike) but I could NOT verify any specific scheduled US macro data release dated 2026-09-25 — that gap is flagged, not filled.

2. Key Findings (with confidence levels)

…(truncated — the summary above captures the substance)

Round 0 · Finding 6

US Equity & Macro Recap — 2026-09-26 Window

0. Headline correction you must read first: there was no 2026-09-26 US equity session

2026-09-26 is a Saturday. Verified directly in-session: new Date('2026-09-26').getUTCDay() returned 6 and toUTCString() returned "Sat, 26 Sep 2026" (browser eval call). US cash equities (NYSE/Nasdaq) do not trade Saturdays. The finance_data feed independently confirms this: every symbol I pulled returns "last_bar": "2026-09-25 13:30:00" — i.e. the most recent completed daily bar is Friday 2026-09-25 (finance_data analyze, symbols SPY, DIA, QQQ, IWM, MSGY et al.).

Consequently:

• "Today's session" = Friday 2026-09-25. Everything below is labeled with that date. I am not presenting it as a 2026-09-26 session.
• The only genuinely 2026-09-26-dated content is the weekend news flow (geopolitics, trade truce) that sets up Monday 2026-09-28.
• The mission's requirement for "biggest movers on 2026-09-26" and "macro drivers dated 2026-09-26" cannot be met as literally stated because markets were shut. I substitute the immediately adjacent session (Sep 25) and the Sep 26 weekend news window, each explicitly dated.

1. Index closes — Friday 2026-09-25 (the last US session before the 2026-09-26 weekend)

Important data-availability flag: I could not fetch any US index directly. finance_data analyze returned "no data" for ^GSPC, ^DJI, ^IXIC, ^RUT, ^SPX, ^NDX, ^VIX, ^TNX, ^TYX, ^FVX, ^IRX, ES=F, NQ=F, YM=F, RTY=F (tried across NASDAQ, NYSE, AMEX, OTC, BATS, CBOE, TVC, SP, DJ, CME, CME_MINI and more). The index levels below therefore come from a fetched secondary source and are corroborated by ETF proxies I did pull from the tool.

From the fetched nightly digest (https://stockmarketwatch.com/digest/2026-09-25 — datePublished: 2026-09-25T21:06:38Z, article creator is listed in its own JSON-LD as the "Stock Market Watch automated reporting system", so treat as an automated secondary source):
