About Robert Barrow's insider trades
Robert Barrow is Chief Executive Officer at Definium Therapeutics (DFTX). Since May 25, 2022, Robert has reported 1 open-market purchase worth $6K and 25 sales worth $3.3M on SEC Form 4. In the last 12 months: 2 sales ($1.9M).
2 sales (8% 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 (9 filings), shares withheld for taxes (5 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 DFTX insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
