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	16.04	27% pctile · Near median	13.5 ─ median 17.2 ─ 31.1	2026-09-29
VXN · QQQ	22.07	35% pctile · Near median	17.2 ─ median 23.3 ─ 33.5	2026-09-29

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.

📏Range Forecast

Today's Range Forecast (pre-open)

⚠ 数据陈旧：本预测基于 2026-09-29 的日线（距今约 9 天）。落盘日线可能未更新（检查 PostClose_Rebuild 任务），下面的数字不可用于今日决策。

This section answers one question only: how far price is likely to swing between the open and the close (high minus low). It does not forecast direction — the directional version has been backtested repeatedly and produced no reliable signal.

Symbol	Tier	Forecast day range	80% interval	vs last 20d
SPY	Low	0.70%	0.41% ~ 1.24%	About normal
Today is likely to be calmer than usual — price has less room to move. Selling options is favoured and normal strike width is fine. Long straddles are unfavourable today: you need a big move just to break even. Stops can be tightened somewhat.
QQQ	Normal	1.08%	0.66% ~ 1.83%	About normal
A normal day with no particular signal. Run your usual parameters; no volatility-driven adjustment needed.

How to read this table
· Forecast day range: how far today's high is from today's low, as a percentage of the current price.For example 0.70% above means the day's high and low are expected to differ by about 0.70%.
· 80% interval:on 8 days out of 10 the actual value lands between 0.41% and 1.24%; on the other 2 it falls outside. That is the honest error band — the real value may be half the forecast, or half again as large.
· Tier: days are bucketed into large / medium / small. When it says “High”, about 6 times out of 10 the day really is large, versus barely 3 in 10 for a blind guess. Good enough to size positions and choose strike width; not good enough to compute precise P&L.
· “Tier” and “vs last 20d” can look contradictory, and that is normal: the tier compares against the past several years, the right-hand column against the last 20 days. “High tier but about normal” means the recent period has itself been high-volatility — today is not exceptional, but the overall environment is jumpy and position sizing should stay cautious.
· A 10:00 intraday revision email follows, folding in the actual range and volume from the first half hour; the forecast gets sharper then.

ΓGamma Map

Symbol	Spot	Net GEX ($B per 1%)	Regime	Zero-gamma flip	Call wall	Put wall	Pin
QQQ	$742.80	+1.42B	Dealers long gamma	$737.21 (spot above)	$745 +0.30% · OI 3,180	$740 -0.38% · OI 5,057	$740

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 | 2026-09-29 (prior session) +0.19% ↔ 2017-09-06 +0.30%; today maps to the day after 2017-09-06, which was +0.23% (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 +0.12% (up 60% of the time, range -1.3% to +1.8%) · 5-day +0.33% (65%) · 20-day +0.47% (65%)
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 1999-03-22–2026-09-29 (6924 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

AAII Retail Sentiment Survey · week of 2026-09-23

Bull−bear spread -15.4 bulls 32.7% / bears 48.1%

39-year percentile 11.8% · 5-year percentile 26.2% (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

30.8 fear

prior close 31.6 · one week ago 32.5 · one month ago 53.7
Percentile since 2022 21.7%

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 · 2026-09-29

0.38 index P/C 1.01 · total P/C 0.76

Percentile since 2023 0% (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.
