[fng-trend-2026-09-19.png]

10-day trend: -18.8 points (47.5 → 28.7)

• 9/3-9/4 still Neutral (47.5, 45.2); 9/8 broke below 40 into Fear (39.1), then continued lower.
• 9/17’s 28.7 is the second-lowest in the 8-day fear span, just above 9/16 (27.3).
• Sample minimum of 5.17 (2025-11-20); current level is ~29 points from the Extreme Fear threshold (0).

Consecutive fear days: 8 (since 9/8, including all trading days through 9/17). Note: 9/1 was Fear (44.9) but 9/2-9/3 returned to Neutral, breaking the streak.

Seven Sub-indicators

Note: Several sub-indicators show internal contradictions between official rating and raw value (e.g., S&P 500 Momentum score 26.4 rated “Fear” while level 7,637 is in the script’s “Extreme Greed” range; Breadth score 0 rated “Extreme Fear” while advancers 628 is in “Extreme Greed”). These arise from the script’s internal normalization mapping and are noted as-is without manual re-rating.

Rating distribution:

• Extreme Fear: 2 (Price Strength, Price Breadth)
• Fear: 4 (S&P 500 Momentum, S&P 125 Momentum, PCR, Safe Haven)
• Neutral: 3 (VIX, VIX 50d, HY Bond Demand)
• Greed: 0

Divergence Analysis and Counter-evidence

Divergence 1: S&P 500/125 Momentum raw level high vs. Fear score

S&P 500 at 7,638 and S&P 125 at 7,368 are at historically high levels (script labels “Extreme Greed”), yet the normalization score is only 26.4 (Fear). This indicates the momentum sub-indicator does not track absolute levels but rather recent momentum direction — the index’s downward trajectory has depressed the momentum score.

Counter-evidence: High levels with low momentum scores mean the index has not broken down (levels remain elevated), but short-term momentum has turned negative. The contradiction signals: no crash yet, but downward momentum is established.

Divergence 2: Price Breadth advancers 628 vs. Extreme Fear score

Breadth raw value of 628.66 falls in the script’s “Extreme Greed” range, yet the score is 0 (Extreme Fear). Same pattern as momentum — absolute breadth remains healthy but the trend of breadth (slope of advancing issues) may be negative.

Counter-evidence: Absolute breadth still healthy means this is not a broad-market sell-off. The deterioration is more likely concentration risk — a few weighty stocks dragging the index, with breadth trend weakening but not collapsing.

Divergence 3: VIX 15.44 (Neutral) vs. Price Strength -3.46% (Extreme Fear)

VIX remains near 15, at historically low levels, while price strength has hit -3.46% Extreme Fear. This suggests implied volatility has not yet priced in the actual decline — either the market is in a “grinding down” phase, or VIX is supported by tail-hedge demand in options pricing.

Counter-evidence: VIX staying flat while prices fall is historically common in gradual correction phases (e.g., the Nov 2025 Extreme Fear period), not V-shaped crashes. This actually increases uncertainty — if VIX breaks above 20, it could trigger accelerated selling.

Credit / Rates / Leverage Cross-verification

[fng-sub-trends-2026-09-19.png]

Interpretation:

Credit spreads (HY OAS 2.70%, IG OAS 0.78%) are both in normal ranges, creating a significant divergence from CNN Fear sentiment. The bond market is not pricing in credit risk deterioration — if the F&G decline were driven by fundamental deterioration, credit spreads should widen in tandem. Instead, spreads remain compressed, suggesting sentiment-driven weakness outweighs fundamental deterioration.

The 10Y-2Y has turned positive at +0.25% (previously inverted for an extended period), which is a relatively positive signal. However, the 10Y-30Y remains at -0.35%, meaning the long-end curve inversion persists.

On the leverage side (margin debt, IPOs, ETF inflows), all three flash red. $1.304T in margin debt is at a historical high range, and 2026 YTD ETF net inflows of $856B are at record levels. This means that despite fear sentiment, leveraged capital has not retreated — should sentiment reverse or an external shock trigger margin calls, these crowded positions could amplify volatility.

Conditions for Risk Escalation or De-escalation

Risk escalation signals:

• HY OAS breaks above 3% into warning zone, or 5% into panic zone
• VIX breaks above 20 and holds, accompanied by further price strength deterioration
• 10Y-2Y re-inverts deeply (below -20bp)
• Margin debt shows month-over-month decline (first sign of top formation)

Risk de-escalation signals:

• F&G index reclaims 50+ (Neutral territory) and holds for 3 consecutive sessions
• Price Strength turns positive (>0%)
• HY OAS compresses further below 2%
• Breadth trend stabilizes (advancers not making new lows for 5 consecutive sessions)

Data Limitations

• CNN Fear & Greed data as of 2026-09-17 (UTC); 9/18 (Wednesday) data to be confirmed whether already ingested by the script.
• FINRA margin debt latest release is Apr 2026, 5 months stale; cannot reflect current leverage levels.
• IPO count and ETF inflows are YTD cumulative values, excluding marginal changes in the most recent month.
• Internal contradictions between sub-indicator scores and raw values derive from the script’s normalization logic; not manually corrected.
• SPX actual closing price not independently verified against momentum raw values; level data from script output.
