Dave Mazza with Roundhill Investments talks about how much of a "force" retail investors became during the COVID-19 pandemic, seen in the GameStop (GME) craze in early 2021. A resurgence in meme stock plays led Roundhill to relaunch its MEME ETF, which Dave says gives investors the chance to experience volatility stocks like Opendoor (OPEN), Hims & Hers (HIMS), and Rigetti Computing (RGTI) in a "professional" manner. He explains the evolution of the meme stock trade and how the ETF has changed.
