Side by side | 2026-10-06 (prior session) +0.46% ↔ 2025-02-18 +0.23%; today maps to the day after 2025-02-18, which was +0.03% (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 -0.15% (up 50% of the time, range -1.4% to +0.5%) · 5-day -0.60% (45%) · 20-day +0.49% (70%)
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 1999-03-22–2026-10-06 (6929 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”.
