CNN Fear & Greed data pull and cross-validation run on 2026-10-03 CST. Latest data as of 2026-10-02 (US close), composite index 31.2 (Fear), up +3.1 from prior session 28.1. 20 consecutive fear days, sample low 5.2 (2025-11-20). Four of nine sub-indicators in Fear/Extreme Fear. HY credit spreads in alert zone, yield curve normal-flat, margin debt and ETF flows at historical highs.
S&P 500 factor test: prices as of 10-02 (Fri). Value factors (EP/FCF Yield/ROE) persist negative; momentum broadly negative but not significant; low-vol anomaly (negative alpha) strongest signal. 5 of 7 sector momentum sign flips are regime continuation, not today's突变.
Composite index at 28.09 (Fear), in its 18th consecutive fear day. Sub-indicators are heavily diverged: momentum and breadth remain in fear, while volatility (VIX 16.39) and junk bond demand do not yet confirm crisis. Credit spreads have entered警戒 zone, while margin debt and ETF inflows hit record highs -- leverage and liquidity signals create a cross-verification contradiction.
S&P 500 seven-factor cross-sectional test results. Volatility factor IC=+0.117 significantly positive; momentum, EP, FCF Yield, ROE all negative. IT sector momentum flipped from positive to negative,延续 existing regime shift. Fundamental factor IC unchanged since 09-26.
SPX close 2026-09-30: CNN Fear & Greed composite 30.83 (Fear), 17th consecutive fear day. Sub-indicators show severe divergence: price strength and breadth flash extreme fear (0.4 / 0.0), while junk bond demand remains in greed (55.4). Cross-verification shows HY spreads in warning territory, margin debt at record highs, and ETF YTD inflows at all-time levels.

Five sector momentum factors flipped from positive to negative, representing a continuing regime shift rather than a single-day突变. EP, FCF Yield, ROE remain negative. BP and SIZE ineffective.
CNN Fear & Greed Index at 33.94 (Fear) as of 2026-09-28 close, marking the 15th consecutive fear day. Sub-indicators show severe divergence: stock strength/breadth both at 0 (Extreme Fear), VIX at 50 (Neutral), junk bond demand at 64 (Greed). Credit spreads and curve normal; margin debt and ETF flows at historical extremes.

S&P 500 factor analysis as of 2026-09-11: Momentum reversal deepens (IC=-0.20), value factors turned negative, size effect persists. Sector decomposition shows IT momentum IC=-0.48. All reversal alerts are regime continuation, not new events.
CNN Fear & Greed index at 41.86 (Fear) as of 2026-09-04 US close, marking the 6th consecutive trading day in fear territory. Sub-indicators show significant divergence: stock price strength in extreme fear (12.6) while junk bond demand registers extreme greed (76.2). Credit spreads and yield curve signals are benign, but margin debt and record ETF inflows present leverage risks. Note: Data does not include 9/8 or later sessions, likely due to data source update delay.

Momentum IC=-0.214 remains deeply negative; value factors collectively reversed; large-cap leads. 6 of 8 industry momentum sectors negative - an existing anti-momentum regime continuation, not a new flip today.
Composite score 41.9 (Fear), as of 2026-09-05. Fifth consecutive fear day. Seven sub-indicators show a stark divergence: junk_bond_demand reads extreme greed while most others sit in fear/neutral territory. Credit spreads normal but margin debt and ETF inflows at records — leverage signals conflict with sentiment readings.
S&P 500 seven-factor cross-sectional test. Data through 09-08. Momentum, FCF Yield, EP, ROE, SIZE maintain negative IC; VOL still insignificant. Multiple sector momentum 'flip' alerts are continuation of established regime, not today's突变.

Monday Labor Day snapshot (9/7): US markets closed, CNN F&G data frozen at Friday 9/4 close of 41.86 (Fear), consistent with the 9/5 report. Structure remains a rare split: credit firming vs. equity internals crumbling (Junk Bond 76.2 vs. Price Strength 12.6, 63.6-point gap). One material correction on the crash-indicator side: margin debt latest is $1.502T (Jun-26) — a record high (the 9/5 report mislabeled May's $1.417T as July and claimed a record monthly decline; May→Jun was actually +6.1%). HY OAS 2.65%, IG OAS 0.81%, 10Y-2Y +41bp all normal; IPO 105 deals raising $145.8B (🟡); ETF inflows YTD >$1.4T record (🔴). Net: 3🟢/1🟡/2🔴.
Monday pre-market run with no new US trading data (last trading day Fri 09-04) — all numbers identical to the weekend brief: momentum reversal persists for an 11th consecutive day, market-wide momentum IC -0.2225, ICIR -1.96, t-stat -12.07, only 2.6% positive cross-sections, long-short spread +6.76% monotonic; IT sector momentum IC -0.516 (long-short +20.71%) remains the most negative sector, Financials (IC -0.300) and Industrials (IC -0.252) keep weakening, Real Estate remains the only significant positive-momentum sector (IC +0.197, p=0.006); volatility factor IC +0.034 still insignificant (p=0.266), value factors stay broken. Anomaly detection: same momentum sign-flip alarms as yesterday persist (11th day), no new alert types; six sectors' z-scores all in the 2.2~2.9 band (IT/Financials/Industrials/Utilities/Cons Disc/Cons Staples), Real Estate no longer triggers, Utilities p-value lost significance (0.236) alert retained.
Sunday morning snapshot (9/6): The CNN Fear & Greed Index remains at Friday's 9/4 US close reading of 41.86 (Fear). No new data since yesterday's (9/5) report — no trading over the weekend, and Sept 7 is Labor Day (NYSE closed), so the next update comes after Tuesday's (9/8) close. ⚠️ Correction: yesterday's report said the "next trading day" was 9/7; that was wrong — 9/7 is the Labor Day holiday. The API history series now appends a duplicate 9/4 23:59 timestamp (41.86), a CNN closing-stamp artifact with no substance. The structure still shows the rare two-pole divergence of "credit improving vs. single-stock breakdown": junk bond demand 76.2 (extreme greed, spread ratio 1.2303) vs. stock price strength 12.6 (extreme fear, -0.7936, new 2026 low). The composite index sits at the upper edge of the fear zone (41.86, only 3.1 pts from the 45 neutral line) consolidating after a +35.4% three-day rebound from the 9/1 low of 30.91. Pre-crash indicators also show no change (FRED: HY OAS 2.65%, IG OAS 0.81%, 10Y-2Y +41bp all normal; margin debt $1.417T in July with record single-month decline 🔴, IPO proceeds $145.8B 🟡, ETF inflows YTD >$1.4T 🔴). Composite 3🟢/1🟡/2🔴, unchanged from yesterday.
Sunday run with no new US trading data (last trading day Fri 09-04) — all numbers identical to yesterday's brief: momentum-reversal persists for a 10th consecutive day, market-wide momentum IC -0.2225, ICIR -1.96, t-stat -12.07, only 2.6% positive cross-sections, long-short spread +6.76% monotonic; IT sector momentum IC -0.516 (long-short +20.71%) remains the most negative sector, Financials (IC -0.300) and Industrials (IC -0.252) keep weakening, Real Estate remains the only significant positive-momentum sector (IC +0.197); volatility factor IC +0.034 still insignificant (p=0.266), value factors stay broken. Anomaly detection: same momentum sign-flip alarms as yesterday persist (10th day), no new alert types; IT/Financials z-scores eased from >3σ to ~2.9 band, Real Estate no longer triggers, Utilities p-value lost significance (0.236) alert retained.
Saturday morning snapshot (9/5): CNN FNG updated through the Friday 9/4 close at 41.86 (fear). IMPORTANT: CNN has retroactively revised the 9/2-9/3 history today (continuation of the junk-bond indicator algorithm revision) — 9/3 was revised up from 35.26 (as reported yesterday) to 43.91 (+8.65), 9/2 from 33.23 to 32.97 (-0.26), while the API's previous_close field (35.23) still shows the pre-revision value and is deprecated. On the revised basis, 9/4 (41.86) is down -2.05 pts from 9/3 (43.91), and the composite has rebounded +10.95 pts (+35.4%) in three sessions from the 9/1 low of 30.91 — a materially stronger rebound than yesterday's data suggested. S&P 500 fell -0.38% on 9/4 (7,747.71 → 7,718.60), momentum pulled back (42.6 → 36.6); stock price strength made new cycle lows (-0.7936, score 12.6 extreme fear); safe-haven demand collapsed (0.9931 → 0.1714, score 26.0) — equity-side risk-off is deepening. Junk bond demand flipped violently: the HY/IG spread ratio tightened from 1.3470 to 1.2303 (-8.7%), score flipping from yesterday's 12.2 (extreme fear) to 76.2 (extreme greed), partly due to the algorithm revision. Structure shows a rare "credit warming vs equity breakdown" divergence. Crisis dashboard (FRED 9/3): HY OAS 2.65% (-1.0bp), IG OAS 0.81% both normal, 10Y-2Y +41bp normal-flat (-2bp); margin debt $1.417T July (MoM -5.6%, record largest monthly drop, RED), IPO 2026 proceeds $145.8B (105 deals) +542% (YELLOW), ETF inflows YTD >$1.4T record (RED). Summary 3 GREEN / 1 YELLOW / 2 RED.
US close Fri (09-04) incorporated: momentum-reversal persists for a 9th consecutive day with IT sector IC at a new low — market-wide momentum IC -0.2225, ICIR -1.96, t-stat -12.07, only 2.6% positive cross-sections, long-short spread +6.76% monotonic; IT sector momentum IC deepened to -0.516 (long-short +20.71%), Financials (IC -0.300) and Industrials (IC -0.252) keep weakening, Real Estate remains the only significant positive-momentum sector (IC +0.197); volatility factor IC +0.034 still insignificant (p=0.266), value factors stay broken. Anomaly detection: same momentum sign-flip alarms as yesterday persist (9th day) — IT/Financials beyond 3σ, Industrials/Consumer Discretionary/Staples/Utilities beyond 2σ positive-to-negative, Real Estate +2σ high, Utilities p-value lost significance (0.236). No new alert types; Utilities is the only alert upgraded today.
Friday morning snapshot (9/4): CNN FNG updated to 9/3 (Thursday) US close at 35.26 (Fear), up 2.0 points from the 9/2 close of 33.23 — the second straight session of marginal stabilization. S&P 500 rallied +1.06% on 9/3 (7,666.60 → 7,747.71), driving a major momentum repair (32.6 → 42.6, +10.0), the main lift behind the composite's recovery; safe-haven demand (0.4006 → 0.9854, +0.58; score 28.6 → 34.6) strengthened for a 3rd straight session and broke above the 0.5 watch line, adding to signs of a phase-one risk-off easing. However, stock price strength hit a fresh cycle low (-0.533 → -0.633, score 15.8 extreme fear), and junk bond demand remains at its post-revision extreme (12.2 extreme fear; spread ratio 1.3478 → 1.3470, roughly flat) — the full risk-off structure is unchanged. Since the 9/1 crash low of 30.91, the composite has recovered +4.4 points (+14.2%) over two sessions, but still sits mid-Fear: 10 points above the extreme-fear line (25) and 5 points above the June bottom band (24.66-29.97). Crisis precursors (FRED 9/2): HY OAS 2.66% normal (up +1.0bp), IG OAS 0.81% normal, 10Y-2Y +43bp normal-ish flat (+3bp vs prior); margin debt July $1.417T -5.7% MoM (🔴 record largest monthly drop), IPO 2026 proceeds $145.8B / 105 deals (Renaissance caliber) +542% (🟡), ETF flows YTD >$1.4T record (🔴). Total 3🟢/1🟡/2🔴.
US close Thu (09-03) incorporated: momentum-reversal persists for an 8th consecutive day with new lows on both fronts — momentum IC -0.221, ICIR -1.92, t-stat -11.84, only 2.6% positive cross-sections, long-short spread +6.75% monotonic; IT sector momentum IC deepened to -0.506 (long-short +20.38%), Financials (IC -0.298) and Industrials (IC -0.248) keep weakening, Real Estate remains the only significant positive-momentum sector (IC +0.209); volatility factor IC +0.030 still insignificant (p=0.325), value factors stay broken. Anomaly detection: same momentum sign-flip alarms as yesterday persist — IT/Financials beyond 3σ, Industrials/Consumer Discretionary/Staples beyond 2σ positive-to-negative, Real Estate +2σ high, Utilities p-value lost significance (0.416). No new alert types.
Thursday morning snapshot (9/3): CNN FNG updated to 9/2 (Wednesday) US close at 33.23 (Fear), up 2.3 points from the revised 9/1 close of 30.91. ⚠️ Major data event: CNN revised the junk bond demand sub-index algorithm (scoring direction flipped) after the 9/2 close, and the 9/1 composite index was retroactively revised from 44.57 (as reported yesterday) to 30.91 (-13.7 points); the 8/31-9/1 single-day drop was revised from -2.9 points to -16.6 points — sentiment is actually weaker than yesterday's report suggested: the revised 9/1 reading of 30.91 broke below the 7/29 low of 34.66, the lowest since 4/8/2026 (29.17), one step from the June bottom band (24.66-29.97). Post-revision, junk bond demand at 11.4 (extreme fear) now matches stock price strength at 17.0 (extreme fear); yesterday's core divergence ("credit greed vs equity fear", 88.8 vs 21.2) disappeared with the algorithm fix, and no sub-index is in greed territory — a full risk-off structure. On 9/2 the junk bond spread ratio widened sharply from 1.2140 to 1.3478 (+0.134) — the credit deterioration is real and directionally consistent with FRED HY OAS rising (2.63%→2.65%), though the absolute level remains normal (<3%). Crisis precursors (FRED 9/1): HY OAS 2.65% normal, IG OAS 0.81% normal, 10Y-2Y +40bp normal-ish flat; margin debt July $1.417T -5.7% MoM (🔴 largest monthly drop on record), IPO 2026 proceeds $145.8B / 105 deals (Renaissance caliber) +542% (🟡), ETF flows YTD >$1.4T record (🔴). Total 3🟢/1🟡/2🔴.
US close Wed (09-02) incorporated: momentum-reversal persists for a 7th consecutive day and deepens in Tech — momentum IC -0.215, ICIR -1.79, t-stat -11.03, only 2.6% positive cross-sections, long-short spread +6.61% monotonic; IT sector momentum IC fell further to -0.484 (long-short +19.56%), Financials (IC -0.290) and Industrials (IC -0.242) keep weakening, Real Estate remains the only positive-momentum sector (IC +0.217); volatility factor IC +0.026 still insignificant (p=0.389), value factors stay broken. Anomaly detection: 5 sectors keep triggering momentum sign-flip alarms (positive-to-negative) — IT/Financials beyond 3σ, Consumer Discretionary/Staples/Industrials beyond 2σ, Real Estate +2σ high, Utilities p-value lost significance.
Wednesday morning snapshot (9/2): CNN F&G updated to 9/1 (Tuesday) US close at 44.57 (Fear), down another 5.1 pts from 8/31 close of 49.71. Second straight session below the 50 neutral line since the 8/13 peak of 66.6, lowest since 7/29 (46.32), and now formally in Fear territory (<45). Trend: after the 8/31 breakdown from the 53-57 band, 9/1 extended the decline and is testing the 45-49 support zone (late-July lows 45.23/41.2). Internals keep deteriorating but show two marginal shifts: stock price strength (0.19 to -0.27, score 21.2 extreme fear) turned negative for the first time since late July; safe haven demand (-0.02 to 0.23, score 28 fear) ticked up with the 20-day stock/bond excess return turning positive. Breadth (975.1, neutral) keeps falling, put/call (0.743) protection buying rose for a 4th straight session, VIX 16.34 up but still low. Junk bond demand (88.8 extreme greed) pulled back 5 pts from 93.8 with the raw spread ratio widening 1.205 to 1.214 — the credit/equity divergence (88.8 vs 21.2) narrowed to 67.6 pts but stays extreme. Crisis-side no new deterioration (FRED 8/31): HY OAS 2.63% normal, IG OAS 0.80% normal, 10Y-2Y +40bp normal-flat; margin debt July $1.417T -5.7% MoM (high but off record), IPO 2026 ~$160.6B +542% (near record), ETF inflows YTD $1.23T record. Net 3 green / 1 yellow / 2 red.

Anomaly detection: 5 sectors triggered momentum sign-flip alarms (positive-to-negative) — Consumer Discretionary/Staples/Financials/Industrials/IT all beyond 2-3σ, Real Estate +3σ high, Utilities p-value lost significance.
Tuesday morning snapshot (9/1): CNN Fear & Greed updated to 49.71 (Neutral) at Monday 8/31 US close, down 2.6 pts from Friday 8/28 close of 52.31 — the first reading back below the 50 neutral line since the 8/13 peak of 66.6, and the lowest since 8/3 (50.74). 8/31 was a decisive downside break: after 7 sessions of 53-57 range oscillation, the index broke down, taking out both the 53.06 and 53.94 double-bottom supports. Internal structure deteriorated broadly: Stock Price Strength (0.486→0.190, score 25 extreme fear) and Safe Haven Demand (1.46→-0.008, score 25.4 fear) collapsed on the same day; Breadth fell back from greed to neutral (53.8); only Junk Bond Demand (93.8, extreme greed) hit a fresh high — the credit-vs-equity divergence widened to 68.8 pts (11th consecutive session). Put/Call (0.696) hedging continued to build; VIX ticked up to 14.92 but remains low. No new deterioration on the crash-signal side (FRED 8/28): HY OAS 2.60% normal, IG OAS 0.79% normal, 10Y-2Y +41bp normal; margin debt $1.417T in July -5.7% MoM (🔴 high but retreating), IPO 2026 ~$145.8B +542% (🟡 near record), ETF inflows YTD $1.23T record (🔴). Summary 3🟢/1🟡/2🔴.
The US Monday (08-31) close is now incorporated: the momentum reversal pattern continues and deepens — momentum IC -0.205, ICIR -1.62, IC positive rate just 2.6%, long-short spread +6.36% and monotonic. IT sector momentum IC deepens further to -0.442 (long-short +18.25%); Financials (IC -0.277) and Industrials (IC -0.230) keep weakening, while Real Estate remains the only positive-momentum sector (IC +0.231, positive 75% of periods). Volatility IC turns positive (+0.017) but stays insignificant (p 0.587); value factors keep failing. Anomaly detection: 6 of the 8 covered sectors trigger momentum sign-flip alerts (positive to negative), with deviations beyond 2-3σ across IT/Financials/Industrials/Utilities/Staples/Discretionary.
Monday early-morning snapshot (Aug 31): US market still in weekend (Sun evening ET, ~12h before Monday open), CNN F&G latest reading remains the Aug 28 (Fri) close of 54.4 (neutral), same source as yesterday's report, data unchanged. Aug 28 close fell 3.7 pts from 58.2 prior day; the Aug 27 break above 57.2 was rejected within a single session, breakout-failure risk persists, index sits mid-band of the 53-57 range awaiting Monday direction. Structural divergence persists: safe-haven demand (3.00→1.46 single-day collapse, 39.8 fear), Put/Call (81.8→73.2 put-protection return) leaning defensive, junk bond demand (90.2 extreme greed) new high, stock price strength (29 fear) rising 3rd straight day to 0.486 — credit/equity divergence 61.2 pts (10th straight session). No new deterioration in crash precursors (FRED 8/27): HY OAS 2.63% normal, IG OAS 0.79% normal, 10Y-2Y +39bp normal-ish flat; margin debt Jul $1.417T MoM -5.7% (🔴 high), IPO 2026 ~$144B +631% (🟡 near record), ETF inflows YTD $1.23T record (🔴).

Monday-morning routine update; the US market has not opened yet — all indicators in this report are identical to the 08-30 report (which incorporated the US Friday 08-28 close): momentum IC stays at -0.204, ICIR -1.62, IC positive rate just 2.6%, long-short spread +6.39% and monotonic. IT sector momentum IC -0.434 (long-short +17.89%) remains the most negative sector-wide and at a stage high; Financials (IC -0.270) and Industrials (IC -0.228) keep weakening, while Real Estate remains the only sector with positive momentum (IC +0.234). Volatility remains insignificant (p 0.948) and value factors keep failing. Anomaly detection flags deviations across all 8 covered sectors, 6 of which flipped from positive to negative with deviations generally beyond 3σ. The momentum reversal pattern is unchanged since Friday's close.
Weekend snapshot (8/30 Sun): the latest CNN FNG reading is still the 8/28 (Fri) close of 54.4 (Neutral), the same source as yesterday's report — 8/29-8/30 are non-trading days, so sentiment readings are frozen at Friday's close. The 8/28 close fell 3.7 points from the prior 58.2; the 8/27 break above 57.2 was undone within a single session, breakout-invalidation risk is rising, and the index has returned to 53-57 chop. The pullback was driven by Safe Haven Demand (3.00→1.46 one-session collapse, 56.2→39.8 into fear) and Put/Call (81.8→73.2, put protection drifting back); meanwhile Junk Bond Demand (90.2, extreme greed) hit a fresh high and Stock Price Strength (29, fear) recovered for a 3rd day to 0.486 — the credit/equity divergence widened to 61.2 points (10th session). No new deterioration on the crisis side (FRED 8/27): HY OAS 2.63% normal, IG OAS 0.79% normal, 10Y-2Y +39bp normal-flat; margin debt July $1.417T MoM -5.7% (🔴 elevated), IPO fundraising $160.6B through 8/19 approaching the 2021 record (🟡), ETF inflows YTD $1.23T record (🔴).

Sunday non-trading day, no fresh data — all indicators in this report are identical to the 08-29 report (which incorporated the US Friday 08-28 close): momentum IC stays at -0.204, ICIR -1.62, IC positive rate just 2.6%, long-short spread +6.39% and monotonic. IT sector momentum IC -0.434 (long-short +17.89%) remains the most negative sector-wide and at a fresh stage high; Financials (IC -0.270) and Industrials (IC -0.228) keep weakening, while Real Estate remains the only sector with positive momentum (IC +0.234). Volatility remains insignificant (p 0.948) and value factors keep failing. Anomaly detection flags deviations across all 8 covered sectors, 6 of which flipped from positive to negative with deviations generally beyond 3σ. The momentum reversal pattern is unchanged since Friday's close.
As of the 8/28 (Fri) close, FNG stood at 54.4 (Neutral), down 3.7 points from the prior day's 58.2 — yesterday's break above 57.2 was pulled back within a single session, risking a false breakout, and the index has returned to range-bound chop within the 53-57 band. The pullback was driven mainly by Safe Haven Demand (56.2→39.8, 20-day stock vs bond excess return collapsing 3.00→1.46 in one session) and Put/Call (81.8→73.2, P/C 0.6675→0.684 with put protection drifting back in); meanwhile Junk Bond Demand (90.2, extreme greed) hit a fresh high (+3.4) and Stock Price Strength (29, fear) recovered for a third straight day to 0.486 — the internal divergence between credit and equities widened to 61.2 points (10th consecutive session). No new deterioration on the crisis-signal side: HY OAS 2.63% normal (-4bp), IG OAS 0.79% normal, 10Y-2Y +39bp normal-ish flat (narrowed 8bp), margin debt July $1.417T MoM -5.7% (🔴 elevated), IPO fundraising $160.6B through 8/19 approaching the 2021 record (🟡), ETF inflows YTD $1.23T record (🔴).

Friday routine update: as of 06:46 Beijing time (Thu 16:46 ET), incorporating the complete US Thursday (08-28) close — the fifth trading day this week with fresh data. Momentum reversal confirmed for a fifth consecutive day, with market-wide intensity stabilizing at high levels for a second straight day — momentum IC -0.204 (basically flat vs Thu -0.203), ICIR -1.62, IC positive rate holding at 2.6%, long-short spread +6.39% still monotonic. The five-day sequence (-0.192 → -0.199 → -0.205 → -0.203 → -0.204) shows the reversal neither deepening nor fading. IT sector momentum IC -0.434 (widened from Thu -0.421) remains the most negative with a fresh record long-short spread of +17.89%; Financials (IC -0.270) keep weakening; Industrials (IC -0.228) edge up; Consumer Staples (IC -0.167) keep converging. Anomaly detection flags deviations in all 8 covered sectors, 6 of which flipped from positive to negative. The only exception remains Real Estate — momentum IC +0.234 (z +4.40), the only sector where momentum stays positive. Utilities flipped negative but lost significance entirely (p 0.496); Health Care stays insignificant (p 0.085). Sector coverage continues across 8 GICS industries.
8/27 (Thu) close FNG 58.2 (Greed), +3.0 vs prior 55.2, breaking above the 8/19 high of 57.2 — confirming the 53.1/53.9 double-bottom support, the first valid breakout signal within the pullback channel from the 8/13 peak of 66.6. The rally is driven mainly by Put/Call (81.8, extreme greed, P/C 0.703→0.667 as put protection exits) and Market Momentum (37→44, S&P 500 rebounding to 7,731); Stock Price Strength (28.2, fear) ticked up to 0.441 for the first time after a two-day collapse (0.63→0.44→0.41) — a positive internal signal, yet still in fear zone. Junk Bond Demand (86.8, extreme greed) vs Stock Price Strength (28.2) divergence of 58.6 pts persists for the 9th straight session (narrowed 2.8 from 61.4). Crisis side unchanged: HY OAS 2.67% normal (-3bp), IG OAS 0.80% normal, 10Y-2Y +47bp normal-flat, margin debt July $1.417T MoM -5.7% (🔴 high), ETF inflows YTD $1.23T record (🔴). Total 3🟢/1🟡/2🔴.

Friday routine update: as of 06:46 Beijing time (Thu 16:46 ET), incorporating the complete US Thursday (08-27) close — the fourth trading day this week with fresh data. Momentum reversal confirmed for a fourth consecutive day, but market-wide intensity shows the first signs of stabilization: momentum IC -0.203 (basically flat vs Wed -0.205, marginally weaker), ICIR -1.61, IC positive rate recovering from 0.0% to 2.6% (one of 39 cross-sections now positive), long-short spread +6.38% still monotonic. IT sector momentum IC -0.421 (widened from Wed -0.409) remains the most negative with a fresh record long-short spread of +17.54%; Financials (IC -0.261) keep weakening, while Industrials (IC -0.224) and Consumer Staples (IC -0.175) ease at the margin. Anomaly detection flags deviations in all 8 covered sectors, 6 of which flipped from positive to negative. The only exception remains Real Estate — momentum IC +0.235 (z +4.76), the only sector where momentum stays positive. Utilities flipped negative but lost significance entirely (p 0.369); Health Care stays insignificant (p 0.112). Sector coverage continues across 8 GICS industries.
8/26 (Wed) close FNG 55.2 (Greed), down 3.6 pts from prior 58.8 (CNN same-date historical series shows 8/25=56.8; readings are subject to daily retroactive revisions). The 8/19 high of 57.2 was not reclaimed and support at 55 is being tested again. New deterioration inside the structure: Stock Price Strength (27, Fear) broke down for a 2nd consecutive day (0.63→0.44→0.41, % of stocks near 52-week highs contracting 0.22 in two days) while Breadth (61.4) strengthened — new highs held but the share of stocks near highs collapsed, concentration into a few mega-caps is accelerating. Junk Bond Demand 88.4 (Extreme Greed) vs Stock Price Strength 27 gap of 61.4 pts persists for an 8th trading day (narrowing 3 pts from 64.4). Crisis side unchanged: HY OAS 2.70% normal, IG OAS 0.81% normal, 10Y-2Y +47bp normal, margin debt Jul $1.417T -5.7% MoM (🔴 elevated), ETF inflows YTD $1.23T record (🔴). Composite 3🟢/1🟡/2🔴.

Thursday routine update: as of 06:48 Beijing time (Wed 16:48 ET), incorporating the complete US Wednesday (08-26) close — the third trading day this week with fresh data. Momentum reversal confirmed for a third consecutive day and still deepening: market-wide momentum IC -0.205 (further down from Tue -0.199), ICIR -1.64, IC positive rate down to 0.0% (none of 39 cross-sections positive), long-short spread +6.49% and monotonic. IT sector momentum IC -0.409 (from Tue -0.385) remains the most negative with a fresh record long-short spread of +17.22%; Industrials (IC -0.227) and Financials (IC -0.246) keep weakening, while Consumer Staples long-short widened to +6.39%. Anomaly detection flags deviations in all 8 covered sectors, 6 of which flipped from positive to negative with deviations generally beyond 3.5σ. The only exception is Real Estate — momentum IC +0.231 notably high (z +4.86), the only sector where momentum stays positive. Health Care keeps losing significance (p 0.219). Sector coverage expanded to 8 GICS industries (Real Estate and Utilities newly added).
Wednesday routine update: as of 07:17 Beijing time (Tuesday 19:17 ET), full Tuesday (08-25) US close data has been incorporated — the second consecutive trading day of confirmation, with the momentum reversal still deepening. Market-wide momentum IC -0.199 (vs Monday -0.192), ICIR -1.63, IC positive rate only 2.6%, long-short spread +6.19% and monotonic; IT momentum IC -0.385 (vs Monday -0.353) remains the most negative sector with long-short spread +17.00%, a new high; Industrials (IC -0.223) and Financials (IC -0.246) continue to weaken. Anomaly detection shows momentum IC flipped positive to negative in 5 of 6 sectors with deviations mostly beyond 3.5σ; Health Care significance disappeared (p 0.509). Today's sector breakdown covers only 6 GICS sectors; Utilities and Real Estate are not in the sample.

Routine update after US market close: as of 06:45 Beijing time (Mon 18:45 ET), this run includes the full trading data from Monday's (08-24) US close — the first regular update this week with fresh session data. Momentum reversal is now confirmed by actual close data and deepening — market-wide momentum IC -0.192 (worse than Friday's -0.180), ICIR -1.46, IC positive rate 5.1%, long-short spread +6.13%; IT sector momentum IC -0.353 (long-short +14.20%) remains the most negative and its deviation is widening, Financials (IC -0.228) and Industrials (IC -0.217) keep weakening, while Real Estate remains the only positive-momentum sector (IC +0.211). Anomaly detection shows momentum IC flipping from positive to negative in 7 of 8 sectors with deviations mostly beyond 4σ — the unwinding of crowded momentum trades is accelerating, not repairing.
Pre-market Monday snapshot; FNG data still frozen at the 8/21 (Fri) close of 55.2 (Greed) — no new session over the weekend through Monday pre-market. Today's US open (9:30 ET / 21:30 Beijing) will produce the first fresh data point and test whether the 55 line holds. The internal structural divergence persists: Junk Bond Demand 95.8 (Extreme Greed) vs Stock Price Strength 29.4 (Fear) — a 66.4-point gap for the 6th trading session. Crisis-signal side unchanged: HY OAS 2.75% (8/20) normal, 10Y-2Y +50bp normally steep, margin debt $1.417T in July with the first -5.7% MoM decline (red/high zone), ETF inflows at a record $1.23T YTD (red).
