The Markets' Volatile Week, Roku Plunges As Part of "TMT Disaster," Cramer says "Start to Buy" Meta, Cathie Wood's "Very Undervalued" Message and the SPAC Sell-Off

One day after the Dow's worst performance of the year, Carl Quintanilla, Jim Cramer and David Faber drilled down on a volatile week for stocks as Russia-Ukraine tensions remain front and center. Roku also in the spotlight after its shares plummeted on weaker-than-expected revenue and guidance -- adding to a rough week for so-called TMT stocks (technology, media and telecom) including DraftKings, Palantir and Roblox. Cramer explains why he thinks now is the time to buy Facebook parent Meta Platforms. Separately, new data show that Meta has fallen off the list of the world's ten most valuable companies. Also in focus: ARK Invest CEO Cathie Wood tells CNBC that her Innovation ETF is "very undervalued," venture capitalist Chamath Palihapitiya steps down as Virgin Galactic chairman, why SPACs are continuing to tumble, and Intel CEO Pat Gelsinger tells analysts that the chipmaker can become the "next great growth story." Is he right?
