ARK Invest ETFs, such as the ARK Innovation ETF (NYSEMKT:ARKK), have been under scrutiny so far in 2021. After a standout 2020, the ETF has taken a breather in 2021. The goal of ARKK, an actively managed ETF, is to invest in "disruptive innovation" over the long term. Cathie Wood has been very vocal in explaining that the fund invests with the goal of multiyear holdings, capturing gains from secular growth trends and disruptive technology. 

ARKK invests in the following themes:

  • Genomic revolution
  • Industrial innovation
  • Next-generation internet
  • Fintech innovation

Goldman Sachs (NYSE:GS) recently created the Goldman Sachs Future Tech Leaders ETF (NYSEMKT:GTEK), which invests in companies it thinks will be the next big winners in technology. GTEK, like ARKK, is actively managed. However, the fund focuses on a more global approach. Goldman Sachs believes it can take advantage of its 80-plus analysts scattered across the globe to find the best opportunities with a more balanced approach. Both ETFs focus on businesses with smaller market caps, but GTEK specifically focuses on an all-cap strategy, blending large and small businesses under a $100 billion market cap.
