Syun-Ming Jang: trading record in brief
Syun-Ming Jang is a declared insider of Taiwan Semiconductor Manufacturing Co Ltd, with filings sourced from SEC (Form 4). In total, 5 filings cover trades dated from 9 April 2026 to 7 October 2026.
Every open-market trade on record is a purchase: 5 purchases worth €16k, and no sale. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant.
A typical purchase (the median) is worth €3,181. Relative to company size, the median is 0.0000% of market cap (4 purchases with a known value). 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.
Most recently, on 8 October 2026, the filings show an open-market purchase worth €3,247 in Taiwan Semiconductor Manufacturing Co Ltd. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. 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.
