Zensei

Zensei is an investment-analytics platform that shows which sectors and stocks are beating the S&P 500, and how risky the market is today, for self-directed investors who want a repeatable top-down routine.

- Zensei Index: one 0–100 score for US equity risk, updated every trading day. Lower is healthier. The score falls into one of four regimes (Supportive, Vulnerable, Stressed, Restrictive) and combines ten indicators.
- Zensei Edge: a sector rotation map of 115 sectors, themes and asset classes, each measured against the S&P 500 over six windows from one week to one year. Drill down from a leading group to the stocks inside it.
- Free public pages for every sector, theme and the most-searched stocks.
- MCP access: Premium connects Zensei to Claude, ChatGPT and other AI assistants, so they answer with live market data.
- Chrome extension: today's Index and the 11 S&P 500 sectors, one click away.

Free tier for the Index and the 11 broad sectors. Premium is $49/month or $399/year, cancel any time. Zensei provides analytics and education, not investment advice.
