On the news front, Broadcom reported earnings on June 4, delivering Q2 total revenue of $22.19 billion that beat expectations and AI revenue of $10.8 billion representing 145% year-over-year growth. However, the company's Q3 AI chip revenue guidance of approximately $16 billion fell short of the market consensus of $16.3 billion, and the CEO did not raise the full-year AI revenue target. Broadcom subsequently plunged 12.59% in a single session, with selling pressure rapidly spreading to the storage sector.
