Yi-Huang Wu: trading record in brief
Yi-Huang Wu is a declared insider of Taiwan Semiconductor Manufacturing Co Ltd, with filings sourced from SEC (Form 4). Over a trading history stretching from 7 July 2026 to 7 October 2026, the count stands at 4 filings.
On the market, this insider has only ever bought: 4 purchases, €11k in total. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant.
The median purchase comes to €2,617. 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: 3 out of 3 purchases overlapped with buying by a colleague within 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.
The record was last updated on 8 October 2026 with an open-market purchase (€2,753) in Taiwan Semiconductor Manufacturing Co Ltd. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. For comparison, the SEC allows two business days to file a Form 4. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
