QuantOrb.pro — one of the services developed by kfchow.com

QuantOrb.pro (this site) is one of the services developed by kfchow.com — the lab behind the LLM Value Leaderboard, an independent ranking of AI models by real-world value per dollar.

QuantOrb applies the same engineering standard to market rotation: every trading day, the 11 US GICS sector ETFs are re-ranked by three transparent technical signals (money flow, relative strength, volume pressure), and every claim is labelled with its sample size and margin of error. All 501 holdings across the 11 ETFs are mapped with zero gaps, one page per holding — 13F institutional ownership included, straight from SEC public-domain data.

We publish the formulas, the 28-year back-test, and the honest labels. The signals are technical rotation indicators — not dollar capital flows, and not investment advice.
