Kenneth J. Widder

Filings by Kenneth J. Widder span 3 companies, the busiest being QuidelOrtho Corp, Quidel Corp and Personalis, Inc. Over a trading history stretching from 12 May 2021 to 12 May 2026, the count stands at 15 filings.

The filings describe grants, exercises and other transfers rather than trades on the open market. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.

The latest filing, published on 14 May 2026, reports a share grant in Personalis, Inc. Typically, a trade is published a median of 2 days after it takes place. 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.
