Qualifying buys · 30d: eligible common-stock purchases by trade date in the 30 days through October 12, 2026, using the company snapshot.
30-day filing activity: eligible purchases from filings accepted by the SEC in the last 30 days. Acceptance dates can differ from trade dates.
Value used in Signal Score: qualifying purchases across 180 days, weighted by transaction age. The calculation and exact value are in “Why this Signal Score?” below. These totals measure different windows and should not be added together.
Signal Score summarizes disclosed corporate insider buying over up to 180 days. It is separate from Congress activity and the 30-day purchase total, and does not measure company quality, investment safety or profit probability.
