About Mark A Welsh III's insider trades
Mark A Welsh III is a director at Northrop Grumman (NOC). Since Aug 29, 2024, Mark has reported no open-market purchases and 17 sales worth $477K on SEC Form 4. In the last 12 months: 5 sales ($281K).
17 sales (100% of the value sold) were made under a Rule 10b5-1 trading plan, which is set up months in advance and runs on a schedule, so they say little about how the insider sees the stock today.
Their filings also include grants and awards (8 filings), other transactions (3 filings). These aren't open-market trades and aren't counted above.
How to read insider trades
Officers, directors and owners of more than 10% of a company must report trades in its stock on SEC Form 4, usually within two business days. Purchases with their own money are the stronger signal: insiders sell for many reasons (taxes, diversification, a house), but buy for one. See every NOC insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
