While Rule 10b5-1 plans are designed to ensure compliance, their systematic execution—such as Farquhar's repeated sales on September 8th, 10th, 12th, and 15th—has led some analysts to question whether these plans are being used to exploit market volatilityAtlassian stock at risk as insiders sell the expensive TEAM shares^[1].
