Chue-San Yoo: trading record in brief
All filings by Chue-San Yoo on record concern Taiwan Semiconductor Manufacturing Co Ltd. Over a trading history stretching from 9 April 2026 to 7 October 2026, the count stands at 5 filings.
Every open-market trade on record is a purchase: 5 purchases worth €17k, and no sale. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket.
In size, the median ticket on the buying side is €3,414. Measured against the company's value, the median purchase equals 0.0000% of market capitalisation, across 4 purchases where it is known. Clusters matter here: 4 out of 4 purchases overlapped with buying by a colleague within 30 days. Purchases made close together by different insiders form what is called a cluster.
The record was last updated on 8 October 2026 with an open-market purchase (€3,529) in Taiwan Semiconductor Manufacturing Co Ltd. Typically, a trade is published a median of 2 days after it takes place. The legal deadline for a Form 4 is two business days after the transaction. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
