Founder, StockPik
I built StockPik because I got tired of running value investing calculations in Excel. Pulling two years of financial statements per company, checking the nine Piotroski criteria one by one, computing Graham Numbers manually — it works fine for a handful of stocks. Across a few thousand names, it's impractical.
StockPik automates that process across 6,000+ US-listed stocks using data directly from SEC EDGAR filings, updated weekly. No analyst estimates, no third-party data suppliers — just what companies have officially filed with the SEC.
I write about value investing metrics: what they measure, where they come from, where they break down, and how to use them in combination rather than in isolation. The goal is to make the kind of systematic analysis that used to require expensive data terminals accessible to individual investors.
