Stephen Kaufer: trading record in brief

Stephen Kaufer, listed as chief executive, has filed trades across 2 companies (mainly through SEC (Form 4)), most often in CarGurus, Inc. and TripAdvisor, Inc. We count 67 filings; the first trade dates from 27 February 2012 and the latest from 3 June 2026.

The open-market side counts 3 purchases for €2.5M alongside 23 sales for €21.5M. Sales outweigh purchases by €18.9M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Outside the open market, there are 23 share grants and 15 option exercises. So far in 2026, the count stands at 1 purchase and no sales.

Half of the purchases are above €855k and half below. After 3 purchases with a full 90-day history, the hit rate stands at 67% and the median 90-day move at +19.5%. This is a record of the past, not a forecast.

On 4 June 2026 came the latest disclosure, a share grant in CarGurus, Inc. The most recent open-market purchase was published on 4 March 2026, 249 days ago. Typically, a trade is published a median of 2 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
