A comprehensive list of the best tools and resources for investment research.
Each year, we update our comprehensive list of the best equity research tools available for both institutional and individual investors. While Bloomberg and FactSet continue to dominate the professional market with all-in-one solutions, their cost (often exceeding $30,000 per seat annually) places them out of reach for many. Fortunately, a growing set of platforms offer powerful, affordable, and even free alternatives.
This year, we’ve not only refreshed existing tools but also added new platforms gaining traction in insider trading monitoring, expert calls, AI-driven research, and filing navigation. To make this more usable, we’ve grouped tools into eight categories:
- Full-Service Market Intelligence Platforms (Bloomberg Alternatives)
- Market Data & Fundamental Analysis
- Forensic Research & Fraud Detection
- Insider Trading & Institutional Ownership Monitoring
- Expert Call Aggregators
- SEC Filing Search & Navigation
- Equity Research Aggregators & Communities
- APIs, Quant Platforms & AI Tools
