Wood’s funds, including her flagship Ark Innovation ETF, bought 341,186 shares in total on Thursday, according to data released by the funds in an email. That takes Ark Investment Management LLC.’s Coinbase purchase past 1 million shares.

Separately, Ark’s funds have sold shares in New York Stock Exchange parent Intercontinental Exchange Inc. for two consecutive sessions, the emailed data showed.

Ark Investment, founded by Wood in 2014, invests in companies involved with disruptive trends, which means it has a limited pool of targets in which to deploy that money. Concerns have swirled around the New York-based firm in recent months on concentration risks after a stellar year saw ETF assets surge at one point to more than $60 billion.
