Marc Grandisson is a declared insider at 2 companies (chief executive); the most frequent names are Arch Capital Group Ltd. and Howard Hughes Holdings Inc. The record holds 21 filings, for trades running from 5 May 2021 to 23 September 2026.
Market trades split into 1 purchase (€1.4M) and 3 sales (€42.2M). Taken together, the sales exceed the purchases by €40.8M. 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 8 share grants and 4 option exercises. So far in 2026, the count stands at 1 purchase and no sales.
Most recently, on 24 September 2026, the filings show an open-market purchase worth €1.4M in Howard Hughes Holdings Inc. Typically, a trade is published a median of 4 days after it takes place. Section 16 rules allow two business days to file each Form 4. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
