What is ARK Innovation ETF?
ARKK is an actively managed ETF run by Cathie Wood that invests in companies ARK Invest believes are leaders in disruptive innovation, including areas like AI, genomics, fintech, and autonomous vehicles. Unlike index ETFs, ARKK's holdings are chosen by a portfolio manager, which means performance depends heavily on the manager's stock-picking ability. Beginners should understand that ARKK is a high-risk, high-reward fund that can deliver spectacular gains or devastating losses.
ARKK is managed by ARK Invest and has been available since 2014. With $6.5B in assets under management, it's a growing fund that has attracted significant investor interest. The fund charges an expense ratio of 0.75%, which means for every $10,000 you invest, you pay approximately $75 per year in management fees.
