About Barbara G McClung's insider trades
Barbara G McClung is Chief Legal Officer at Caribou Biosciences (CRBU). Since Oct 20, 2021, Barbara has reported 2 open-market purchases worth $41K and 2 sales worth $18K on SEC Form 4. In the last 12 months: 1 sale ($14K).
2 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 (5 filings), option exercises (4 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 CRBU insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
