Woofun AI reports that the global semiconductor sector faced continued weakness, with Japanese leader Kioxia dropping 16% in a single day and falling approximately 50% from its one-month peak. Peers Renesas Electronics, Tokyo Electron, and Sumitomo Metal Mining declined between 8% and 10%. The Philadelphia Semiconductor Index (SOX) retreated roughly 21% from its June 22 high, entering a technical bear market. TSMC shares fell 7% despite raising guidance after beating earnings expectations.

Institutional analysis attributes the adjustment to crowded positions and profit-taking rather than fundamental deterioration. Citi data indicates semiconductor ETFs in South Korea and the Taiwan region of China recorded net inflows of $6.4 billion and $2.8 billion respectively this week. South Korean equities also attracted approximately $500 million in foreign net inflows, suggesting some capital is accumulating on the dip.
