The Taiwan stock market closed lower as TSMC weighed on the index, though strong performance in AI-related stocks and memory manufacturers helped limit losses.

What Happened

Market Performance: The Taiwan stock market experienced a volatile session, closing down 214.90 points at 44,396.70. While TSMC's 40-point drop significantly dragged down the index, the market maintained a robust trading volume of 940.4 billion TWD, indicating continued investor participation.

Institutional Activity: Institutional buying momentum slowed significantly, with a net purchase of only 4.563 billion TWD. While investment trusts and foreign investors remained net buyers, proprietary traders were net sellers, reflecting a more cautious stance among major market participants.

AI and Tech Momentum: Capital rotated into the AI supply chain and memory sectors to offset weakness in heavyweight stocks. Foxconn saw gains following record-breaking July revenue, while Chuan Hwa became the third stock in Taiwan history to surpass the 10,000 TWD mark, underscoring the sustained demand for AI server components.

Industry Developments: Nanya Technology announced a 346.6 billion TWD investment in a new 5A factory, marking the largest single investment in the domestic DRAM industry in two decades. This move bolstered sentiment for the memory sector, as investors anticipate the start of a new industry cycle.
