Jiang Wei

Jiang Wei’s insider trading activity, as reflected in SEC Form 4 filings, reveals a consistent pattern of acquisitions with no recorded sales, totaling $165,228.98 in buy value across 24 transactions. Wei’s activity spans two companies: Waters Corporation (WAT) and STAAR Surgical Company (STAA). Notably, the majority of transactions involve Waters Corporation, with a significant purchase of $144,730 on March 16, 2026, marking the largest single transaction in the dataset. Earlier activity includes a smaller acquisition of $20,498.98 in Waters Corporation shares on March 28, 2024. Transactions involving STAAR Surgical Company, primarily coded as "M" (merger or acquisition), show no monetary value, suggesting these may represent non-monetary adjustments or transfers rather than direct purchases or sales. Wei’s recent activity underscores a continued focus on Waters Corporation, with the March 2026 purchase being the most substantial in both value and timing. The absence of any sell transactions indicates a strong buy bias, with Wei consistently accumulating shares over time. This pattern suggests a sustained interest in Waters Corporation, particularly given the significant investment in early 2026. While STAAR Surgical Company appears in the filings, the lack of monetary value in these transactions suggests they play a secondary role in Wei’s portfolio. Overall, Wei’s trading behavior reflects a clear preference for acquiring equity in Waters Corporation, with no indication of divestment across the observed period.
