What is fomo5000.com?

FOMO5000 is a static market visualization that plots more than 5,000 US-listed stocks on a single interactive chart. The project is a JavaScript web app deployed at fomo5000.com, where you can scan the entire US stock market at a glance without an account or any trading platform. Each stock is positioned along two axes. The horizontal axis represents an estimated AI relevance score, derived from each company's official sector and industry classification plus a small adjustment based on the semantic content of company descriptions. The vertical axis shows how market capitalization has changed over selectable periods: one week, one month, three months, six months, and twelve months. Colors indicate the Nasdaq sector, small triangle angles reflect the week's price movement, and a time slider lets you step through weekly snapshots going back to January 2025. The dataset currently includes 5,292 stocks with data through late May 2026. The market cap figures are approximations calculated from historical closing price returns, with the assumption that share count stayed constant over time. The AI relevance score is described in the README as an experimental sorting signal and is not investment advice. The project is built as a static site. A build script splits a large JSON market data file into smaller shards, and running the build writes deployable files into a dist folder. In production, a GitHub Actions pipeline deploys to Cloudflare Pages automatically from the main branch, with credentials stored in GitHub environment secrets rather than in the repository. Source code is under the MIT license. The market data included in the repository is not covered by that license and remains subject to the terms of the original data providers. The README is written in Chinese.
