Filings by Denis K. Sheahan span 2 companies, the busiest being Cambridge Bancorp and Eastern Bankshares, Inc. Over a trading history stretching from 22 January 2018 to 3 September 2026, the count stands at 30 filings.

In open-market terms, that means 9 purchases worth €696k on one side and 1 sale worth €12 on the other. Netting one side against the other leaves €696k of net buying. 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 14 share grants and 3 option exercises. In 2026 alone, the filings show no purchases and 1 sale.

Half of the purchases are above €34k and half below. On 9 out of 9 purchases, another insider of the same company was buying within the same 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

The newest entry dates from 4 September 2026: a share grant of €79k, in Eastern Bankshares, Inc. The last purchase on record was published on 26 August 2025, which is 421 days ago. 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.
