Many investors like to check how much of a company is owned by insiders. A high insider ownership often makes company leadership more mindful of shareholder interests. CME Group insiders own 0.3% of the company, currently worth about US$285m based on the recent share price. I like to see this level of insider ownership, because it increases the chances that management are thinking about the best interests of shareholders. CME Group shares are trading up 0.34% at $277.22 at the time of this writing on Monday morning. With strong derivatives clearing volumes reported in May, CME stock price could challenge the $220 mark in the next few sessions. The company’s international expansion is expected to drive incremental revenue streams from Asia-Pacific rate and FX contracts.
