Alphabet's $500B Loss Hits Samsung and SK Hynix as AI Profit Doubts Grow

news.yahoo.co.jp (Japanese) —

Alphabet's market value lost $500 billion in a single day after its stock plunged 12.6%, triggering declines in Samsung Electronics and SK Hynix despite their record earnings, as investor focus shifts from AI growth speed to profitability. Samsung Electronics fell 3.02% and SK Hynix dropped 7.08% on October 30, dragging the KOSPI down 3.48%. Both companies posted record semiconductor operating profits of about 190 trillion won in Q3, with HBM sold out through 2029, yet AI investment concerns overshadowed strong fundamentals. Big tech firms face negative free cash flow from massive AI infrastructure spending, with Alphabet at minus $9.1 billion and Amazon at minus $42.4 billion over the past year. These companies have doubled bond issuance to $230 billion in 2026's first nine months, raising concerns about debt refinancing by 2027-2029.
