ARK's thematic ETFs can overlap due to the conversion across different technologies. Investors looking for broad exposure to innovation tend to gravitate towards ARKK. (Note: ARKK is not a "fund of funds." Rather, it is our cornerstone fund combining all of our research and investment themes.) As stated in the prospectus, the other ARK ETFs offer more targeted exposure. While there is some overlap between the different funds, it is not uncommon for investors to own multiple ARK ETFs. Please consult an investment professional to decide which ETFs are best for your investment needs.
