Michael Toporek

Michael Toporek (chief executive) discloses dealings in 2 companies, chiefly Soluna Holdings, Inc and Capstone Holding Corp. Over a trading history stretching from 25 March 2022 to 7 August 2026, the count stands at 20 filings.

Market trades split into 3 purchases (€156k) and 5 sales (€129k). On balance, insiders were net buyers of €28k. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Besides market trades, the filings include 9 share grants. Since January 2026: 1 purchase and no sales on the market.

The median purchase comes to €1,340.

On 11 August 2026 came the latest disclosure, a share grant in Capstone Holding Corp. The last purchase on record was published on 24 July 2026, which is 86 days ago. Typically, a trade is published a median of 4 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
