TSMC led Taiwan Stock Exchange block trades (privately negotiated large-share transactions) on August 13 with a 2.78 million-share deal worth NT$6.77 billion, or about $210.5 million, accounting for more than 40% of the combined value of the day's top 20 transactions. Hon Hai ranked second at NT$579 million, or about $18.0 million, while MediaTek and AirTAC-KY recorded multiple trades tied to institutional position rotation. The top 20 rankings showed 10 securities above NT$100 million across semiconductors, electronic components and optical components, with Largan Precision and the Yuanta Taiwan Top 50 ETF also making the list. The report said the August 13 market showed "contracting volume with stable prices": the top 20 totaled about NT$9.27 billion versus roughly NT$3.24 billion on August 12, but excluding TSMC's single NT$6.77 billion trade left about NT$2.5 billion, which it characterized as an underlying slowdown. Analysts cited in the article said high-priced electronics stocks and other index heavyweights (large stocks with outsized benchmark influence) remained the focus of institutional trading, but cooling momentum suggested a more cautious stance near previous highs.
