tl;dr: Chip stocks shed over $400 billion Monday, with Intel falling another 9% following its 29% crash on Oct. 30 — leaving it worth less than half its late-September value. Memory and storage names (Micron, Sandisk, Seagate, WDC) dropped 6-8%, and Marvell slid after announcing a $115 billion deal to buy Lumentum, while Nvidia held up relatively well. Overall, chip and memory stocks have lost roughly $3.7 trillion in market cap since Oct. 6, though some analysts believe last week's sell-off marked a bottom.
