Marvell $MRVL Crashes 28%: Worst Week Since 2001 After Luminar Deal

If your portfolio had a rough week, congratulations, you're in excellent company. The S&P 500 dropped 4.36% and the Nasdaq plunged 5.52% on Thursday alone, wiping out $2.3 trillion in market value in a single session. The VIX, everyone's favorite anxiety thermometer, surged nearly 70% to 28.18. Bloomberg's trading desk coined the new acronym for the week: FOGO, or Fear of Getting Obliterated. Accurate.

The proximate cause was the Democratic midterm sweep, which flipped the House and Senate and sent AI infrastructure investors into full panic mode. Roughly 40 ballot measures restricting data center development passed across the country, according to Bloomberg Businessweek, and Democrats winning governorships in Texas and Ohio specifically spooked the picks-and-shovels crowd that had been betting on those states as data center hubs. The Philadelphia Semiconductor Index posted its second-largest single-day drop ever at 12.3%, a decline not seen since March 2020.

The week's clearest casualty was $MRVL, down 28% for its worst weekly performance since 2001, a stat that deserves a moment of silence. The damage came from two directions at once: post-midterm AI selling pressure and a messy $115 billion all-stock acquisition of Lumentum that the market immediately hated. $LITE (Lumentum) fell nearly 40% on the week, with CEO Michael Hurlston going on CNBC to point out the obvious disconnect between strong demand in his actual order book and what the stock price was doing. Nobody cared. When sentiment breaks, fundamentals become a spectator sport.

Fundstrat's Tom Lee called the selloff an overreaction, citing forced hedge fund liquidations in overnight Korea sessions as a key accelerant rather than genuine fundamental deterioration. That tracks. When large funds get margin-called simultaneously, prices do things that earnings models cannot explain. Lee's comparison to Liberation Day in April 2025 is apt, though he conceded there's no simple policy reversal knob to turn here, which makes the recovery path murkier.

Not everything bled out. $ABNB surged roughly 12% after posting its fastest revenue growth in three years and announcing a $12 billion buyback, which is what happens when a company actually executes instead of vibing on AI promises. $IONQ gained about 4% after hours and is up 37% year to date, quietly reminding everyone that quantum computing exists and is not currently being regulated by Texas Democrats. And Anthropic filed its S1 targeting a $1.4 to $1.5 trillion valuation on NASDAQ under ticker ANTN, though that number got trimmed from an earlier $2 trillion estimate, which feels like the market sending a memo.

The week that began with the VIX at 19 ended with it at 28 and a new political reality that redraws the AI capex map. The bull case is not dead, but it just had to change its forwarding address.
