U.S. tech earnings miss triggers sharp sell‑off in South Korean chip stocks

Alphabet reported third‑quarter revenue of $127.58 billion, up 25% year‑over‑year but below market expectations, sending its shares down more than 12%. The disappointment spilled over to the United States, where Intel guided Q4 revenue to $15 billion‑$16 billion and missed forecasts, and Amazon’s after‑hours price fell around 4%. In South Korea, Samsung Electronics fell 4.96% to 220,500 won in pre‑market trading and SK Hynix dropped 5.77% to 1.438 million won, pushing the KOSPI to open 2.99% lower at 5,760.35.

The sell‑off highlights heightened volatility for semiconductor stocks that account for roughly half of the KOSPI’s market value, and may prompt investors to reassess exposure to AI‑driven memory demand. The broader market reaction also signals that weak earnings from major U.S. tech firms can quickly depress Asian equity indices.
