CLOU offers equity exposure to cloud computing firms. It holds firms that license and deliver software over the internet by subscription, provide a platform to create software via internet, provide virtualized computing via internet, own or manage data centers or make or distribute related hardware. Firms must have revenue of at least 50% from these activities to make the cut. The index also allows any firm that earns more than $500M from such actions, regardless of revenue percentage. Aggregate exposure to such firms is capped at 10%. The index selects firms across the cap spectrum and in developed and emerging markets. It applies no additional filters beyond those defining the space. Stocks are cap-weighted.
