David C. Michaels: trading record in brief
This profile gathers the share dealings of David C. Michaels across 2 companies, led by Soluna Holdings, Inc and Albany International Corp /DE/. Between 31 August 2006 and 12 December 2025, the trades on record add up to 55 filings.
In open-market terms, that means 14 purchases worth €119k on one side and 4 sales worth €585k on the other. On balance, insiders were net sellers of €466k. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. The rest of the record consists of 13 share grants and 18 option exercises. In 2025 alone, the filings show no purchases and 2 sales.
A typical purchase (the median) is worth €5,415. 4 out of 9 purchases came within 30 days of a purchase by at least one other insider of the same company. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. Ninety days after publication, 14 purchases show a median change of -0.6%, with the price up in 36% of them. These figures describe past trades and do not predict future prices.
The newest entry dates from 15 December 2025: an open-market sale of €45k, in Soluna Holdings, Inc. The clock since the last published purchase (20 June 2024) now reads 872 days. Filings reach the SEC (Form 4) feed a median of 1 day after the trade. Section 16 rules allow two business days to file each Form 4. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
