What is Insider Trading on Palantir Technologies Inc.?

Legal insider trading occurs when executives, directors, and major shareholders (>10%) of a public company buy or sell shares of their own company and report it to the SEC via Form 4.

Form 144: filing of a sale notice → imminent sale in the coming days/weeks
