Signal history

Michael Dennis Murphy: trading record in brief

Michael Dennis Murphy appears in our data through filings on Avidia Bancorp, Inc. shares, published by SEC (Form 4). Between 5 November 2025 and 16 September 2026, the trades on record add up to 5 filings.

Every open-market trade on record is a purchase: 4 purchases worth €300k, and no sale. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Other entries cover 1 share grant. Since January 2026: 2 purchases and no sales on the market.

A typical purchase (the median) is worth €86k. On 4 out of 4 purchases, another insider of the same company was buying within the same 30 days. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.

The newest entry dates from 17 September 2026: a share grant, in Avidia Bancorp, Inc. The most recent open-market purchase was published on 16 September 2026, 32 days ago. The median gap between a trade and its publication by SEC (Form 4) is 2 days. US insiders must file a Form 4 within two business days of a trade. Source: insider filings from SEC (Form 4).
