Katherine S. Ngai-Pesic: trading record in brief

All filings by Katherine S. Ngai-Pesic on record concern Silvaco Group, Inc., in the capacity of senior executive. Over a trading history stretching from 31 July 2024 to 11 August 2026, the count stands at 11 filings.

The open-market side counts 1 purchase for €89k alongside 3 sales for €642k. Netting one side against the other leaves €553k of net selling. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Outside the open market, there are 5 share grants. So far in 2026, the count stands at no purchases and 1 sale.

The newest entry dates from 12 August 2026: a share grant, in Silvaco Group, Inc. The latest purchase dates back some time: it was published 312 days ago, on 10 December 2025. The median gap between a trade and its publication by SEC (Form 4) is 5 days. US insiders must file a Form 4 within two business days of a trade. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
