Ranked by %B ascending — which names are on sale — not by momentum. Measured on the AI complex over the 2023+ wave, forward 60 days: buying dips beat simply holding by +3.47 pts, while buying strength lost 2.65 pts and top-quartile 12-month momentum lost 3.01 pts. Owning the complex at all was worth +17.95%, which is roughly five times what the timing overlay adds. These are daily entries on the names as they stand today (in-sample, overlapping); the quarterly portfolio test further down did not confirm the dip rule.
Descriptive only. Nothing on this page was measured by regime, so it does not change a verdict. Broad risk-off = QQQ below its 200-day with VIX ≥ 25 or up 20% in 5 days; sector washout = SOXX below its 200-day or under 40% of the AI list above theirs.
Descriptive only; no verdict reads it. A theme leads for a few years and then hands over (the COVID winners kept dipping through late 2021 H2 and did not recover; a one-off analysis, not a committed result). "Breaking" = the theme's equal-weight basket is under its own 200-day while at least 40% of its names sit in the dip band at once; that threshold is a display choice, not a tested rule.

%B says where price sits inside its normal trading channel. Below 0.20 means it has pulled back to the bottom of that channel — on sale. Above 1.00 is extended: too stretched to buy, and it returned 2.65 pts below simply holding.
Two studies disagree, so this is not a filter the verdict column applies. 46 large caps, 15y, fwd 60d: dips above the 200-day hit 71% vs 68% below — better odds, but below-200d averaged slightly more (+7.16% vs +6.96%). The AI complex, 2023+: dips below the 200-day were the best bucket of all, +7.49 pts vs the null. The Meta trade in the box below was 11.8% below its 200-day. Above = steadier; below = bigger and lumpier. Pick per your tolerance.
Both halves are gates, and 2y pos is often the binding one. p10 is the 10th-percentile outcome across past 2-year holds — your unlucky-but-realistic case; a −50% p10 means one in ten 2-year holds halved. These are the exact thresholds the verdict column applies, not a rule of thumb.

Breadth is context, not a trigger. Reproduce every number here with scripts/soxx_breadth_study.py (8 years of SOXX, entry at the next open). Broad strength has no edge: top-10 weight above its 20-day > 80% was +0.04 pts vs the null at 20 days (n=727; +0.00 at 5d, −0.03 at 1d). Weakness in the holdings (breadth < 20%, or their composite %B < 0.20) pointed the same way as SOXX's own dip signal but smaller (about +0.7 to +0.9 pts vs +1.3) and rests on a few hundred overlapping observations, so treat it as noise-level: it adds nothing you cannot read off SOXX's own %B. Use this table to see why SOXX moved, broad or one name, and take the direction call from SOXX's %B. SOXL and SOXS are daily-reset products and are not rated on this page.

%B above 1.00 — the stall zone, −2.65 pts vs the null at 60 days. Not a short signal; a not-today signal.

Buy the dip names at each quarter-end, hold to the next, versus the same number of names drawn at random from the same list (2000 draws), after 0.20% costs. Thresholds were written before each run. Neither variant cleared them, so nothing here changes the verdicts above. The universe is today's AI leaders, which flatters dip entries; the mean is carried by one quarter (2026-03-31) in v1.
| Test | signal qtrs | mean net excess | qtrs positive | ex best qtr | p vs random | result |
|---|---|---|---|---|---|---|
| v1 · dip (%B < 0.20) | 23 | +4.2 pts | 52% | +1.0 pts | 0.071 | not promoted (failed: P1, P4) |
| v2 · dip + above 200-day | 18 | +3.3 pts | 39% | -4.8 pts | 0.259 | not promoted (failed: P1, P3, P4, P5, P6) |
The 1–3 year durability gate cannot be tested point-in-time on 10 years of data (needs 2016 prior sessions); it is judged forward only. Method and thresholds: docs/experiments/2026-09-24-preregistration-qr-s1-v{1,2}.md.
Daily entries at the next open on the 34 AI stocks over 10 years, edge vs every session for the same names. The rule was fixed before this ran: the grid can only demote the default, never pick a different cell. Result: not demoted — it sits on a plateau. Deeper dips test a little better and every cell is positive, but the default edge is +1.31 pts over 10 years, well below the +3.47 pts measured on 2023+ alone.
| edge vs null, pts | 20d | 40d | 60d | 90d |

By year (default cell): 2016 +0.5% · 2017 +2.2% · 2018 +2.1% · 2019 +4.1% · 2020 +8.1% · 2021 +3.2% · 2022 +3.8% · 2023 +4.4% · 2024 +3.5% · 2025 -3.3% · 2026 +4.2%
By market: QQQ above 200 +0.72% · QQQ below 200 +2.16%
Same rule on indices since 1999 (no hand-picked names): QQQ +0.58% · SPY +0.85% · XLK +0.39% — positive on at least 2 of 3. Episodes are counted per name, and the names dip together, so the independent count is far lower than the raw one. Source: scripts/quarterly_rotation/robustness.py.
