Wei Jiang: trading record in brief
Filings by Wei Jiang span 2 companies, the busiest being Waters Corp /DE/ and Staar Surgical Co. The record holds 22 filings, for trades running from 14 July 2021 to 30 September 2026.
Every open-market trade on record is a purchase: 1 purchase worth €127k, 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. Outside the open market, there are 18 share grants and 3 option exercises. Since January 2026: 1 purchase and no sales on the market.
Most recently, on 2 October 2026, the filings show a share grant in Waters Corp /DE/. The clock since the last published purchase (18 March 2026) now reads 214 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. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
