St. Petersburg, Florida-based Ark Invest has since mid-February been piling up shares in Roblox, which had plummeted following worse-than-expected fourth-quarter results.

“Having paid $500 million to its young developer community and continuing to lower barriers to creation with Roblox Studio, Roblox should continue to increase its share of the developer and gamer communities,” Wood had said in a note. 

Roblox operates a free online platform with millions of games and other entertainment experiences made by its own users who are young game creators.

The company has been on Wood’s radar since its public listing in March last year. The popular stock picker has been betting on tech-focused innovation stocks and tends to buy shares in companies on the dip.
