About DMAC insider activity
This page tracks every recent Form 4 filed for DiaMedica Therapeutics Inc. with the U.S. Securities and Exchange Commission. Form 4 is the disclosure that company insiders — officers, directors, and holders of more than 10% of the stock — must file within two business days of buying or selling shares.
The summary above nets open-market purchases against open-market sales over the trailing 90 days. Open-market trades (codes P and S) tend to carry the most signal because they reflect a deliberate choice to put money in or take it out, as opposed to routine grants, option exercises, or tax-withholding events. Use the badges on each row to tell them apart, and always confirm details against the original filing before drawing conclusions.
Frequently asked questions
How often is DMAC insider data updated?
Continuously. We read from SEC EDGAR, so new Form 4 filings for DiaMedica Therapeutics Inc. usually appear here within minutes of being accepted by the SEC.
What does "net insider flow" mean?
It is the total dollar value of open-market insider purchases minus open-market sales over the last 90 days. A positive number (green) means insiders bought more than they sold; a negative number (red) means the reverse.
Why do some rows show grants or option exercises instead of buys?
Insiders receive stock through compensation as well as buying it outright. Form 4 captures all of these. We label each transaction by its SEC code so you can focus on open-market activity if you prefer.
Is this investment advice?
No. InsiderSource presents public filing data for informational purposes only. Insider activity is one of many factors to consider and is never a recommendation to buy or sell.
