Claude

U.S. equity market intelligence
A modern market data platform for investors and researchers.
Research stocks and ETFs, analyze index and sector performance, screen Odin trading signals, and track AI-built virtual portfolios for major indices — all in one place.
AI portfolios for major U.S. indices
Odin500 hosts virtual portfolios built with strategies from major AI engines — Claude, ChatGPT, and Gemini. Each portfolio targets a main index universe with a distinct approach, and you can track live equity, returns, and holdings on the platform.
Index universes
- S&P 500
- Dow Jones
- Nasdaq-100
ChatGPT
Idea-to-rules workflows spanning momentum, rotation, and signal-driven entries.
Gemini
Multi-horizon research styles that blend sector context with index-focused baskets.
Compare Claude, ChatGPT, and Gemini side by side across S&P 500, Dow, and Nasdaq-100 portfolios — each with its own strategy, and transparent performance tracking in virtual books.
Live performance tracking
AI portfolios are simulated and educational. They are not investment advice. Fills use Odin daily closes; past performance does not guarantee future results.
Built for investors, by market-data practitioners
