Insider Alert: DUGGAN ROBERT W Bought SMMT Shares (75/100 Signal)
SMMT
Bought
3,810,000
75/100
This filing scores 75/100, meeting several signal criteria. The purchase size and insider role give the transaction more weight under the scoring model, though some noise factors may partially offset the score.
What to watch: Monitor upcoming earnings dates, any subsequent Form 4 amendments, and cluster activity (multiple insiders buying within a 30-day window). Single filings are most informative when corroborated by broader disclosure patterns.
What this signal means
DisclosureSignals scores every SEC Form 4 filing on a 0–100 scale. This trade earned a 75/100 signal score by weighing the transaction type, insider role, trade size, cluster buying, the insider's own history, and whether the trade was discretionary rather than part of a scheduled 10b5-1 plan. A higher score means the transaction meets more of these predefined criteria — it does not indicate investment merit or expected performance. Insiders generally have up to two business days after a transaction to file Form 4, so the transaction date may be earlier than the filing date. Read the full methodology.
