How to read this · VIX

σ Volatility Indices (VIX / VXN)

VIX = S&P 500 30-day implied volatility (maps to SPY); VXN = the same measure for the Nasdaq 100 (maps to QQQ). Percentile = share of the past year (252 trading days) that closed below the current value.
Index Current Percentile 1-year range As of
VIX · SPY 16.01 24% pctile · Near median
13.5 ─ median 17.2 ─ 31.1
2026-08-20
VXN · QQQ 23.26 50% pctile · Near median
17.2 ─ median 23.3 ─ 33.5
2026-08-20
CBOE official daily closes (VIX from 1990, VXN from 2009). These are closing values, not intraday — the morning brief uses the prior session's close and the evening review the current close, so the series stays consistent with history with no point-in-time bias.

Positive gamma: dealers sell rallies and buy dips, damping moves. Negative gamma: dealers chase, amplifying moves.

Walls are gamma-weighted, not raw OI. 503-day test: a NEAR call wall is real resistance and breakouts through it run shorter; a FAR call wall breaks more often (a volatility tell). Put walls show no measurable support.

Side by side | 2026-08-19 (prior session) -0.20% ↔ 2025-12-15 -0.50%; today maps to the day after 2025-12-15, which was +0.20% (single days are mostly coincidence — the Top-20 statistics below are more reliable)

Top-20 analog statistics (deduplicated — far more reliable than any single day):
Next day mean -0.19% (up 60% of the time, range -2.3% to +1.3%) · 5-day -0.45% (45%) · 20-day +0.84% (75%)
Note: QQQ drifts up over time, so the unconditional probability of any given next day being positive is already about 55%. Compare the “up %” above against that baseline, not against 50%.
25 features in three equally weighted groups: price position (return / distance to moving averages / position in the 52-week range / trend slope / consecutive up-down days / gaps) + technicals (RSI2 / RSI14 / volatility / relative volume / volume trend / range / KDJ-J / Bollinger %B / MACD histogram) + environment (VIX / rate cycle / credit spreads / dollar index / oil / S&P P/E / CBOE equity P/C / AAII bull-bear spread). Weighted z-score Euclidean distance; matching pool 1999-03-22–2026-08-19 (6896 days, excluding ±60 days around the target). Narrative context, not a trading signal: after four rounds of feature engineering the Top-1 next-day directional hit rate tops out at 54.9%, still below the 57% you get by always guessing up. The data is given in full, but do not use it for direction — it answers “which historical setup does today resemble”, not “will tomorrow be up or down”.

🌡Sentiment

NAAIM Manager Equity Exposure · week of 2026-07-29
79.7 ↓ from 84
All-history band: Neutral-bullish (the usual range) (range roughly −5 to 120)
1-year percentile 19.2% · since-inception percentile 31.2% (144 weeks)
How to read: a high percentile means managers are broadly fully invested with little room to add; a low one means broad caution and room to buy back in. Contrarian predictive power is weak (4-week horizon) and the sample has never been tested through a bear market — atmosphere only, not a signal.
AAII Retail Sentiment Survey · week of 2026-08-19
Bull−bear spread -4.4 bulls 35.5% / bears 39.9%
39-year percentile 27.5% · 5-year percentile 45.8% (the distribution has shifted down; use the 5-year figure)
Historically a contrarian indicator, and it takes 3–4 weeks to work, not 1–2. Since 2020 the effect has broken down and at times inverted — low-weight atmosphere only.
CNN Fear & Greed Index · live
55.2 greed
prior close 52.5 · one week ago 64 · one month ago 43.4
Percentile since 2022 58.8%
Backtested: no predictive power for same-day or next-day direction (its components are that day's price action, which makes it circular). Forward absolute returns are positive from every bucket; only the magnitude differs — pure atmosphere.
CBOE Equity Put/Call · 2026-08-20
0.58 index P/C 0.92 · total P/C 0.78
Percentile since 2023 40.2% (median over the same period 0.59)
Low = retail crowding into calls (speculative heat); high = heavy put demand (defensive)
Backtested: an extremely low P/C (call mania) does not mark tops — forward returns are in fact slightly positive, the opposite of the popular claim. Atmosphere only.
All four have been backtested: none carries tradable predictive power for same-day or next-day direction. They describe the sentiment backdrop and are not a basis for buying or selling.
