William L. Atwell

William L. Atwell is a declared insider at 4 companies (senior executive); the most frequent names are Webster Financial Corp, Cigna Corp and Blucora, Inc. The record holds 49 filings, for trades running from 14 July 2006 to 20 August 2026.

Market trades split into 5 purchases (€490k) and 7 sales (€2.2M). The net balance comes to €1.7M on the selling side. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Outside the open market, there are 23 share grants and 12 option exercises.

The median purchase comes to €109k. On 2 out of 5 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.

Most recently, on 21 August 2026, the filings show a transaction in Webster Financial Corp. The most recent open-market purchase was published on 8 March 2022, 1,691 days ago. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. Section 16 rules allow two business days to file each Form 4. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
