Welcome to this week’s edition of CEO Watcher.

This is the only tool that tracks the returns of insiders so we know which insider trades are worth copying.

This week we tracked 982 insider trades and found:

  • UPWK is down almost 25% since we found a director making a large, unscheduled sale

  • Director at QTRX with 73% 1y returns bought $1M of the stock

  • The CEO at IONQ sold $100M

  • and more…

Have a great weekend and thanks for reading!

P.S. Make sure to follow @CEOStockWatcher on Twitter/X as I post more interesting insider trades there each day.

💰 Previous Winner

Large, unscheduled insider sales are one of the highest-signal insider trade types. UPWK is down 20% since we found a director making a large, unusual sale in the May 16th email. The Director also had 40% 3m returns on previous sales and made their largest sale ever.

It opened at $16.94 and is down nearly 25% to $13.14.
