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.

Two brains, one standard of honesty

Reading a market takes both facts and judgment — and blurring the two is how research loses your trust. So we built two sites. QuantOrb is the left brain(this site): deterministic formulas, a 28-year back-test, SEC-sourced institutional data — 0% AI predictions. It is the ground you can verify. Its sister siteAdCho is the right brain: an AI engine that reads the SEC record behind these signals — 13F holdings, 10-K/10-Q text, 8-K press releases — and writes plain-language tear sheets. No price targets, not investment advice. QuantOrb is the ground, AdCho is the reading of it: verify the ground, and treat the reading as one input to your own judgment.
