Are insiders buying or selling ABCL?

Abcellera Biologics Inc (ABCL) has recorded 78 insider buy transactions and 22 sell transactions in the most recent period covered.

What are insider transactions?

Insider transactions are stock purchases and sales by company officers, directors, and 10% shareholders, disclosed via SEC Form 4 filings within two business days of the transaction.

Where can I find ABCL insider trading data?

Abcellera Biologics Inc's insider trading data is sourced from SEC Form 4 filings and lists each transaction by date, insider name, role, transaction type, share count, and price.

What does insider buying signal?

Open-market insider buying is generally interpreted as a positive signal because insiders typically only buy if they believe the stock will rise. Selling can occur for many reasons including diversification, taxes, or 10b5-1 plans, so it's a less reliable signal than buying.
