Broadcom's stock tanked a staggering 15.9% from yesterday's close, hitting $403.01. The company's market cap dropped by over $300 billion in just one day. This marks one of the largest single-day plummets in the history of the U.S. stock market, according to the Financial Times. The crash happened after the company stuck to its previous AI revenue forecast for 2027 ($100 billion) without any upward revision, despite investors expecting a more bullish update. Meanwhile, the financial results beat consensus estimates.
