What this transaction means for investors
Insiders may sell shares for various reasons. It could be a portfolio management move, or fund raising for college tuition or a new home. To avoid the perception that investors might think an insider is trying to time a trade, Rule 10b5-1 was established in 2000. This transaction was performed under that rule.
Viasat's chairman and CEO Mark Dankberg adopted the plan for this sale on Sept. 15. It's likely he wanted to lock in some profits after Viasat shares took off beginning in July. The stock has soared more than 150% from the time the company announced it was chosen to deliver next-generation encryption for U.S. government cloud data centers in late July.
Mr. Dankberg still retained nearly 90% of the holdings in his family trust after this sale. The company is developing a global satellite communications network to power high-quality, dependable, safe, cost-effective, and speedy broadband connections. Viasat could still have plenty of growth ahead, and investors shouldn't consider this transaction as any less conviction in the company by its chairman and CEO.
