One leader per sector, every market day
This page shows the single highest-scoring stock in each market sector by AIQ composite score. It is deliberately not a "best stocks" list — it is a market-structure view. Because every sector is represented regardless of how strong or weak that sector currently is, the interesting information is in the comparisons: how strong is the best Energy name versus the best Technology name, and how is that gap changing?
Changes in sector leadership describe which covered names and sectors moved in the ranking. They do not identify the type of market participant behind those changes or establish a causal flow narrative.
How to read this list
Watch two things. First, the spread: when the top sector leader scores 80 and the bottom scores 45, leadership is concentrated; when the spread compresses, participation is broadening within this list. Second,leader stability: a sector whose leader changes every few days has frequently changing leadership; a sector with the same leader for weeks has more persistent membership in this published ranking. Neither observation identifies investor type or predicts returns.
FAQ
Why does a weak sector still get a leader on the list?
By design. Showing the best name in a weak sector tells you what strength looks like there — and when a weak sector's best name starts scoring meaningfully higher, that is frequently the earliest sign of sector-level repair, visible before the sector aggregate improves.
Where can I see the full ranking within one sector?
Use the screener with a sector filter, or open any leader's stock page and compare it against sector peers from there.
