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.
%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.

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.
