What is AltIndex?
AltIndex is an investment research service that collects company data from across the internet and presents it in a dashboard. Instead of relying only on financial statements, it tracks alternative indicators, including social media sentiment, Reddit mentions, website traffic, app downloads, hiring activity, insider transactions and congressional trading, and blends them with fundamentals into a score for each stock. A portfolio tool reads positions from an uploaded brokerage screenshot and scores every holding. Other parts of the product are daily AI stock picks, configurable alerts, a stock screener, rules-based Autopilot portfolios and a chat assistant that answers questions about holdings using the platform's data. Mobile apps for iOS and Android deliver push notifications, and a developer API and MCP server make the data available to code and AI tools. Nothing here is investment advice; the site links to its own disclaimer.
