What this page tracks
This is a live record of open-market stock purchases by directors and officers of ESS Tech, Inc., sourced directly from SEC EDGAR Form 4 filings. We only count open-market buys — not option exercises or grants — because a personal-money purchase is the cleanest insider conviction signal.
Each filing is scored with our six-factor methodology (fundamentals, financials, technicals, conviction, CEO history, and cluster activity). See how the resulting signals performed against the S&P 500 on the track record, or browse this week's insider buys and the full signal screener.
