The WisdomTree Cloud Computing ETF (WCLD) was the star of cloud computing exchange traded funds last year. It has more to give in 2021. The WisdomTree Cloud Computing Fund seeks to track the price and yield performance, before fees and expenses, of the BVP Nasdaq Emerging Cloud Index, an equally weighted index designed to measure the performance of emerging public companies focused on delivering cloud-based software to customers. Public cloud revenue is one of the many catalysts that can spark more upside for WCLD this year. “According to data presented by Finaria, public cloud revenues jumped by 25% year-over-year amid the COVID-19 crisis and hit $271.9bn in 2020. The increasing trend is set to continue this year, with revenues growing by another 25% YoY to $338b,” notes Finaria.
