About Matthew David Sternberg's insider trades
Matthew David Sternberg is COO, Risk Exchange at Accelerant Holdings (ARX). Since Nov 17, 2025, Matthew has reported 1 open-market purchase worth $75K and 1 sale worth $257K on SEC Form 4. In the last 12 months: 1 buy ($75K) and 1 sale ($257K).
1 sale (100% of the value sold) was made under a Rule 10b5-1 trading plan, which is set up months in advance and runs on a schedule, so it says little about how the insider sees the stock today.
Their filings also include grants and awards (3 filings), shares withheld for taxes (1 filing). 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 ARX insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
