A typical day for Ark Invest's star stock picker Cathie Wood

By: Jen Rogers

By any measure, Ark Invest is having a spectacular run. With tens of billions of dollars flowing into her thematic ETFs and returns that easily surpassed 100% last year, Cathie Wood has gone from being a relatively unknown investor to one of the world’s best known money managers. Ark even took the mantle for largest active ETF from JP Morgan last year. But don’t call her company a behemoth.

“The word ‘behemoth.’ We are like a startup still and we still have that feel, and I never want to lose it,” she told Yahoo Finance Presents.
