Matthew Buten

Matthew Buten discloses dealings in 2 companies, chiefly Biohaven Ltd. and Biohaven Pharmaceutical Holding Co Ltd. The record holds 7 filings, for trades running from 31 December 2021 to 5 January 2026.

Purchases make up the whole of the open-market record (2 purchases, €2.0M). Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Besides market trades, the filings include 3 option exercises.

Most recently, on 7 January 2026, the filings show an option exercise in Biohaven Ltd. The latest purchase dates back some time: it was published 1,108 days ago, on 6 October 2023. Typically, a trade is published a median of 2 days after it takes place. US insiders must file a Form 4 within two business days of a trade. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
