We Spent Months Cleaning SEC EDGAR 13F Data So You Don't Have To

Short summary

AlphaSMO is a free API, CLI, and MCP server built on cleaned SEC EDGAR 13F and Form 4 insider-trading data. The authors spent months solving messy real-world problems: duplicate institution names, CUSIP-to-ticker mapping gaps, staggered quarterly filings, and amendment handling. The tool exposes smart money convergence signals and outputs JSON, tables, or CSV depending on context.

  • •Solved real data plumbing: duplicate CIKs, CUSIP resolution, staggered filings, amendments
  • •Flagship signal: smart money convergence where institutions and insiders both buy
