Shared finance report

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

September 28, 2026

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:
  1. 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

US equities finished 2026-09-28 lower across every index — a modest, rates-driven decline, not a broad risk-off event. The S&P 500 marked ~7,701–7,717 (−0.33% to −0.55%), the Dow ~51,612–51,726 (−0.20% to −0.43%), the Nasdaq Composite ~26,893–26,947 (−0.45% to −0.65%) and the Russell 2000 ~2,820–2,831 (−0.22% to −0.65%). The VIX rose +7.1% to ~15.9. The single clearest driver was the bond market: the 10-year Treasury yield backed up to ~5.24–5.25%, a fresh post-2007 high, with the 5s/10s/30s all ~6.5bp higher in a bear-steepening move — the classic signature of a long-duration equity selloff.

Two caveats govern every number here. (1) These are the latest marks pulled while the session was still in progress, not exchange-confirmed 16:00 ET closes — repeated pulls minutes apart returned different values, and the dispersion is shown below rather than smoothed away. (2) There was no market-wide gainers/losers screen available; the mover list is a hand-assembled candidate batch of 40+ tickers, so larger movers may exist outside it.

The biggest movers in the sampled batch were to the downside: BA −4.66%, META −3.2% to −4.1%, AMD −3.97%, TSLA −3.3% to −3.5%, NFLX −2.24%. The session's largest cross-asset shock was not in equities at all — it was precious metals: GLD −3.5%, SLV −4.7%. Only two of eleven S&P sectors were green (Health Care, Consumer Staples); Communication Services (−1.17%) and Consumer Discretionary (−0.84%) lagged most.

Prior closes (same pulls): ^GSPC 7,742.32 · ^DJI 51,828.62 · ^IXIC 27,068.72 · ^RUT 2,838.20. The structural split in the data: the Dow and Russell 2000 are trading below their 50-day SMAs; the S&P and Nasdaq Composite are above (SPX SMA50 7,640.94 / SMA200 7,209.50; DJI SMA50 52,791.02 / SMA200 50,224.27; IXIC SMA50 26,196.98 / SMA200 24,658.85; RUT SMA50 2,955.16 / SMA200 2,776.54).

The pattern — small caps and the Nasdaq complex weakest, the price-weighted Dow least weak — is consistent with duration/rates pressure rather than a broad growth scare.

What Drove It

Every item below is timestamped 2026-09-28 from the FinancialJuice wire (https://www.financialjuice.com/News/9781995/) or is a dated tool pull.

DriverDated evidence (2026-09-28)What it moved
Long-end yields10-yr ^TNX 5.247% (+6.3bp), 30-yr ^TYX 5.569% (+6.5bp), 5-yr ^FVX 5.072% (+6.5bp) while the 13-wk bill was flat — a bear steepener. WH Sr. Adviser Hassett spoke on 3-month annualized core inflation, 30-yr TIPS yields and bond yields, 16:24–16:46Z.Nasdaq Composite/Nasdaq-100, Utilities (XLU −0.43%), Real Estate (XLRE −0.24%), Russell 2000. The 10-yr level is corroborated: the prior close of 5.184% matches an independently dated 2026-09-25 close.
Volatility bidVIX 15.92–15.94, +7.06% to +7.13%; VVIX 90.55, +3.16%.Confirms genuine hedging demand — this was not a "mixed, nothing happened" day.
Precious-metals liquidationGLD −3.63%, SLV −4.68%. Gold/silver fell with equities rather than acting as a haven.Real-rate pressure, not a fear bid. A dollar-driver explanation is ruled out: the dollar was flat (DXY 101.167, +0.048%).
Iran / oil supply"Iran officials pessimistic about deal with US", "White House official: Trump open to Iran sanctions waiver" (16:22–16:33Z); "Saudi Arabia resumes oil exports via east-west pipeline", Texas Gov. Abbott waives dyed-diesel restrictions (16:39–16:42Z).Energy roughly flat (XLE −0.21% to +0.19%) and crude mixed — supply restoration offset the geopolitical premium.
AI / tech regulation"NYC Speaker: OpenAI, Anthropic, Google all agree…", "Meta also to testify $META" (17:08–17:11Z).META (−3.2% to −4.1%); Communication Services was the worst sector (−1.17%).
Global inflation themeECB's Pereira on inflation pressures and natural-gas price pressures (16:34–16:43Z).Echoed the US long-end move.
BreadthRSP −0.355% vs SPY −0.421% on the day (roughly in line), but RSP −4.681% vs SPY −0.162% over 20 days.The month was extremely narrow; the day was not a breadth event.

Sector detail, all 11 SPDR proxies from a single 2026-09-28 pull: XLV +0.551% (with XLP +0.329% the only two gainers), XLE −0.210%, XLRE −0.241%, XLU −0.430%, XLK −0.438%, XLB −0.442%, XLI −0.663%, XLF −0.720%, XLY −0.841%, XLC −1.173%. The 20-day column is the more telling one: Utilities −7.93%, Real Estate −6.79%, Materials −6.77%, Discretionary −6.47%, Financials −6.29% against Technology +5.24% — a sustained de-rating of rate-sensitive, long-duration sectors while tech holds up.

Cross-asset markers, same session: TLT 78.59 (−0.92%, RSI 28.1, 2.3% of its 52-week range, strong_downtrend) · UUP 28.66 (+0.14%, RSI 69.5, 96.8% of range) · USO 147.62 (−0.48% on the day but +13.82% over 20 days) · Bitcoin ~$83,890 to $84,042 (−0.49% to −0.68%), RSI 63.3, strong_uptrend.

Analysis

The three independent threads converge on one reading: this was a rates-and-volatility session, not a dollar or a growth session. The long end backed up ~6.5bp while the front end didn't move — the precise shape that hurts long-duration equities, small caps and bond proxies. TLT sitting at the 2.3rd percentile of its 52-week range with RSI 28 is the mirror image of a 10-year yield at a post-2007 high, and it is the most stretched reading in the entire dataset. That mechanism explains why the Russell 2000 and the Nasdaq complex were weakest while the Dow was least weak, and why the only green sectors were the two classic defensives.

The two things that didn't fit a risk-off template are as informative as the things that did. Gold and silver fell hard with equities rather than catching a haven bid, which points to forced liquidation under rising real yields. And the dollar was flat, which rules out a currency-driven explanation for either the equity weakness or the metals crash. Meanwhile oil's non-move — despite live Iran headlines — reflects supply restoration (the Saudi pipeline restart) cancelling the geopolitical premium.

Two genuine conflicts surfaced in the pulls and I am not resolving them by preference. Oil direction conflicts directly: WTI was pulled at $93.09 (−0.96%) in one call and $93.13 (+0.78%) in another, and USO ranged from +0.16% to −0.75%. Energy equities were flat-to-slightly-green across every pull (XLE −0.21% to +0.19%), so "oil drove the tape" is not supported either way. Gold's magnitude also conflicts: the futures contract GC=F printed −1.63% while the GLD ETF printed −3.5% to −3.6%. Direction is consistent; size is not.

One backdrop claim should be treated as UNVERIFIED: a search snippet asserted that the FOMC raised the target range to 3.75%–4.00% on September 16, 2026, with CME FedWatch pricing 77.5% odds of another increase at the October 27–28 meeting (behindthemarkets.com). If true it is the macro backdrop for today's yield backup, but I found no primary-record confirmation. A separate snippet citing Brent "near $106" (truthsandnews.com) conflicts with the fetched Brent close of $98.05; I use the fetched value.

Cross-Asset & Equity Recap — US Session, Monday 2026-09-28

Bottom line: This was a rates-and-volatility story, not a dollar story. Equities fell modestly across the board, the 10-year Treasury yield pushed to ~5.25% (a fresh post-2007 high), and the VIX jumped ~7% — while the dollar was flat, gold sold off hard, oil slipped on supply headlines, and bitcoin edged lower. Gold and oil did not confirm a classic risk-off bid; they contradicted it, pointing to real-rate pressure and supply-specific news rather than a flight to safety.

Cross-check on the prior session (BACKGROUND — dated 2026-09-25, not today's move): a week-in-review page states "The S&P 500 closed the week at 7,743.41, up 1.21%… the 10-year Treasury yield closed at 5.184%, its highest since July 6, 2007… the Russell 2000 of smaller companies fell 0.80%" (https://portfolio-terminal.com/blog/stock-market-week-in-review-september-25-2026, surfaced via search). The 7,743 and 5.184% figures line up with the prior-close fields in my tool pull, which corroborates the quote data — but the 1.21% weekly gain is last week's, not today's.

The pattern (small caps and Nasdaq underperforming the Dow) is consistent with a duration/rates-driven selloff.

US Equity Market — 2026-09-28 Session Recap

⚠️ Read this first: two hard limits on what I could verify

(1) I could not fetch the four headline index symbols. Every attempt to pull ^GSPC, ^DJI, ^IXIC and ^RUT (and the alternates GSPC, IXIC, US500, US100, ^SPX) from finance_data returned "no data ... on any exchange (tried: NASDAQ, NYSE, AMEX, OTC, BATS, CBOE, LSE, TSX, TVC, SP, DJ, FOREXCOM, CME, CBOT, COMEX, NYMEX, CME_MINI, ICEUS)". So the literal S&P 500 and Nasdaq Composite closes are UNFETCHED. I substituted index/ETF proxies, which I label as such everywhere below. Two of the four (Dow, Russell 2000) did resolve via the TVC feed and are real index values.

(2) These are not confirmed closing prints. Every series I obtained carries last_bar: 2026-09-28 13:30:00 UTC — i.e. 09:30 ET, the session open stamp — and the freshest news in the feed is timestamped 2026-09-28T17:12:56Z (13:12 ET). The US session was therefore still in progress at the moment of the pull. Treat every number below as 2026-09-28 session-to-date, not a 4:00 p.m. close.

I am reporting this rather than substituting recalled or estimated index levels.


1. Executive Summary

Across four independent index/ETF proxies, the 2026-09-28 session was down and broadly so, with mega-cap tech leading the decline. All four proxies were negative, all four were negative on a 5-day view, and the weakest were the growth-heavy Nasdaq-100 proxy (QQQ −1.038%) and the small-cap Russell 2000 proxy (IWM −0.638%, RUT −0.216%). The cross-asset tape was internally consistent with a yields-up / dollar-up / gold-down session: the long-bond ETF TLT fell 0.92% to the 2.3rd percentile of its 52-week range with RSI 28.1, the dollar ETF UUP rose 0.14% to RSI 69.5, and gold (GLD) fell 3.50%.

Direction call (medium confidence): DOWN / uniformly negative — not "mixed." I can say this because four independent vehicles agree in sign. I cannot state closing levels, because the fetches were intraday.

Confidence: 0.45. High confidence in the direction and relative leadership; low confidence in any level as a "close"; and I failed the task's requirement for index closes, five named single-stock movers, and a VIX/10-year/bitcoin level.

2026-09-28 US Session — Sector Dispersion & Breadth

⚠️ Data-quality and timing caveat (read first)

Every number below comes from a live finance_data tool pull on 2026-09-28. Three material limitations must frame everything:

  1. The index symbols could not be fetched at all. ^GSPC, ^SPX, ^DJI, ^IXIC, ^RUT, ^VIX and ^TNX all returned "no data … on any exchange" across 19 attempted exchanges. I therefore have no index closing level, no VIX level, and no 10-year Treasury yield from a tool. I will not substitute remembered or web-quoted index levels. ETF proxies (SPY/QQQ/DIA/IWM) are reported as ETF prices, not converted into index points.
  2. The session appears to have been in progress, not closed. Every daily bar returned is timestamped 2026-09-28 13:30:00 (= 9:30 a.m. ET, the opening stamp), and the latest wire item in the finance_news pull is timestamped 2026-09-28T17:12:35Z (1:12 p.m. ET). So what I have are intraday readings, not official closes. Two pulls minutes apart returned different values for the same ticker (e.g. SPY −0.616% then −0.421%), confirming live, moving data.
  3. The finance_data feed was intermittently flaky — identical symbols succeeded on one call and failed on the next (XLV, XLP, XLB, XLRE, XLC, XLI, TLT, GLD, SLV, USO, UUP all resolved; XLK, XLF, XLE, XLY never did). BTC-USD returned corrupt data (negative prices, −58.46) and is unusable.

1. Executive Summary

On 2026-09-28 the US tape was down across every index proxy I could fetch, but only modestly, with the tech-heavy Nasdaq complex weakest (QQQ −0.81% to −1.04%) and the Dow proxy least weak (DIA −0.23% to −0.47%). The dominant cross-asset signal was not equities at all — it was a violent precious-metals selloff (GLD −3.53%, SLV −4.47% on the day) alongside a firm dollar (UUP +0.12%, RSI 69) and falling long bonds (TLT −1.14%, RSI 27.4, at the bottom of its 52-week range). Sector leadership was defensive: Health Care (XLV +0.59%) and Consumer Staples (XLP +0.29%) were the only two of the seven sector ETFs I could fetch that were green; Industrials (XLI −0.64%) and Communication Services (XLC −1.16%) lagged. Breadth on the day was not catastrophic — equal-weight RSP (−0.36%) actually out-performed cap-weight SPY (−0.42%) — but the 20-day record is brutally narrow: RSP −4.68% vs SPY −0.16%. The macro driver visible in the dated wire feed was a US–Iran standoff pushing energy/inflation risk, layered on a bond-market/yield story that White House adviser Hassett was publicly addressing mid-session.

Confidence: Medium — the directional and cross-asset picture is well-supported by tool pulls; the absence of index closes, VIX, 10-year yield and any individual-stock % move caps this well below High.

US Market Recap — Monday, 2026-09-28

Critical data-provenance note up front: Every price/percentage below comes from a live finance_data tool call made on 2026-09-28. The tool pulls landed roughly midday–early afternoon ET (the FinancialJuice newswire items I pulled run to 17:08 UTC / 13:08 ET), so the index and ETF levels below are the latest available marks at time of pull, not confirmed 16:00 ET official closes. I flag this rather than present them as settled closes. Where a series or a mover's daily % could not be pulled from a finance tool, I say so explicitly.


1. Executive Summary

The 2026-09-28 US session was a modestly lower, defensively-rotated tape, with the damage concentrated in long-duration/rate-sensitive and consumer-facing equities while health care and staples held green. The Nasdaq Composite was the weakest headline index of the four I pulled (-0.638%), the Russell 2000 close behind (-0.649%), with the Dow the most resilient (-0.202%) — an inversion of the usual large-cap-tech-led pattern.

The dominant macro backdrop was a 10-year Treasury yield at ~5.25% (TVC:US10Y, RSI-14 = 74.2, "strong_uptrend"), a DXY dollar index at 101.09, gold down 3.35% in a single session, WTI crude at $93.13 (+0.78%), and a VIX that jumped 7.06% to 15.92. Sector performance corroborated a rate-shock / geopolitical-risk read: 9 of 11 S&P sector ETFs fell, with Communication Services (-1.17%) and Consumer Discretionary (-0.84%) worst and Health Care (+0.55%) / Staples (+0.33%) the only gainers. Newswire flow dated 2026-09-28 was dominated by US–Iran / Strait of Hormuz headlines and Saudi pipeline restart news, plus White House adviser Hassett commentary on yields and core inflation.

The single biggest gap in this report: the individual-stock mover set. I identified candidate names from dated search snippets (META, NVDA, UAL, MDB, TFX) but did not complete a finance_data pull on any of them, so I cannot give tool-sourced daily % moves for the named movers. That success criterion is not met and is flagged as such.

US Equity Market Recap — Monday, 2026-09-28

Scope note up front (important): Every number below comes from a finance_data / finance_news tool call made during this session. Where a symbol or series failed to return, I say so explicitly and leave the cell empty — I have substituted nothing. Two structural caveats you should read before using the figures:

  1. "Close" vs. bar stamp. The daily bars the tool returned for equities carry last_bar = "2026-09-28 13:30:00" (UTC), i.e. the 13:30 UTC / 9:30 ET session-stamp convention. The tool does not label the bar as a settled official close versus an in-progress daily bar. I therefore report these as the 2026-09-28 daily bar values as returned, not as an exchange-confirmed official close.
  2. Overnight-stamped instruments. VIX (last_bar 2026-09-28 07:15), US10Y (2026-09-27 23:00), WTI (2026-09-27 22:00), Brent (2026-09-27 22:00) and BTC (2026-09-28 00:00) returned bars stamped at or before the US cash open, because those feeds roll on their own clocks. Those stamps are flagged in the cross-asset table.

1. Executive Summary

The 2026-09-28 US session was a modest, broad-based risk-off day with the losses concentrated in the Nasdaq and, on a 20-day view, in the Dow and Russell 2000. As returned by finance_data action=analyze (exchange TVC, interval 1d):

The defining feature of the day was not the equity move — a half-percent is noise — but the cross-asset backdrop: the 10-year Treasury yield printed 5.238%, in the 97.3rd percentile of its 52-week range with RSI(14) at 73.9 and trend flagged strong_uptrend, while WTI sat at $92.32 (+10.63% over 20 sessions) and Brent at $97.35 (+7.36% over 20 sessions).

The dated 2026-09-28 news flow returned by finance_news was dominated by three threads: Iran/Hormuz geopolitics and oil supply restoration, US diesel/SPR supply stress, and fiscal/inflation commentary from White House Sr. Adviser Hassett alongside a bond-market selloff. I can map the Hassett/rates thread and the AI-regulation thread onto specific single-name moves with reasonable confidence; I cannot causally attribute the index move to any single item, and I say so below rather than inventing a narrative.

US Market Session — 2026-09-28: Movers Sub-Question

Scope note up front: This is the movers pillar of the 2026-09-28 recap. Two things must be stated plainly before any number:

  1. No news article body could be fetched. TheStreet and Zacks both returned bot-protection interstitials, and Bloomberg/Yahoo were not fetched. Every "catalyst" below is a search-result snippet only, explicitly labeled as unverified.
  2. The 2026-09-28 daily bars carry a last_bar timestamp of 2026-09-28 13:30:00 (i.e. the session-open stamp on today's daily bar). I cannot confirm from the tool whether the US session had officially closed when the data was pulled, so I label every figure "latest value on the 2026-09-28 bar — not a confirmed official close."

1. What the finance tools actually returned

Index proxies (index tickers themselves all failed)

^GSPC, ^DJI, ^IXIC, ^RUT, ^VIX and ^TNX all returned no data ... on any exchange from finance_data action=analyze. UNFETCHED — no official index closes, no VIX level, no 10-year yield. The only index evidence I have is ETF proxies, pulled 2026-09-28 (finance_data action=analyze, TradingView-backed):

ProxyPrice1d%5d%20d%RSI-14P/ETrend
SPY (S&P 500 proxy)767.56-0.49-0.77-0.2352.2n/fstrong_uptrend
QQQ (Nasdaq-100 proxy)737.96-0.88-0.47+3.0159.5n/fstrong_uptrend
DIA (Dow proxy)515.84-0.32-0.76-3.5941.5n/fdowntrend
IWM (Russell 2000 proxy)280.89-0.38-1.64-5.0333.4n/fdowntrend

n/f = not fetched. No P/E was pulled for any ticker (fundamentals action not run), so that column is empty by necessity, not by omission.

Read-through, with the proxy caveat (QQQ tracks the Nasdaq-100, not the Nasdaq Composite, so it is an imperfect stand-in): the tape was lower across all four size segments on 2026-09-28, with the Nasdaq-100 proxy the weakest (-0.88%) and the Dow proxy the least weak (-0.32%). Small caps (IWM) sit at RSI 33.4 in a downtrend, and the Dow proxy at RSI 41.5 — the weakness is concentrated outside mega-cap tech. This is consistent with, but does not prove, the "Nasdaq falls" framing in the one headline snippet I saw.
