Yang Taiyin

Yang Taiyin is a declared insider at 3 companies (board member); the most frequent names are Gilead Sciences, Inc., Brii Biosciences Ltd. - B and Kronos Bio, Inc. Between 13 February 2006 and 10 September 2025, the trades on record add up to 44 filings.

The open-market side counts 1 purchase alongside 28 sales for €4.5M. The amount is not disclosed for 1 filing. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Other entries cover 1 share grant and 10 option exercises.

On 11 September 2025 came the latest disclosure, a transaction in Brii Biosciences Ltd. - B. The clock since the last published purchase (26 September 2022) now reads 1,489 days. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. The legal deadline for a Form 4 is two business days after the transaction. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
