Big institutional investors dumped Taiwanese shares hard, which is bad news for panel, chipmaking and memory stocks — though the index still held above 48,000.

• Foreign funds sold roughly NT$34 billion in a single day, with local funds selling too.
• Panel maker AUO topped the sell list after a quick run-up on rumors it would team with Intel and TSMC on advanced packaging.
• Memory name Nanya Technology bled the most money because of its high share price; chipmakers UMC and PSMC and heavyweight Foxconn also got hit.
• Not everything fell — circuit board material maker ITEQ jumped to its daily limit as AI server demand sent its profits up more than eightfold.
• Taiwan's market has been setting records, with total value passing India's to become the world's fourth largest.

Outlook: Expect choppy trading into the Mid-Autumn holiday as investors take profits, though history suggests the fourth-quarter tech season usually brings gains back.
