Marshall Durston: trading record in brief

Marshall Durston, listed as senior executive, has filed trades across 3 companies (mainly through SEC (Form 4)), most often in Flat Rock Core Income Fund, Flat Rock Opportunity Fund and Flat Rock Enhanced Income Fund. Over a trading history stretching from 29 December 2021 to 9 December 2025, the count stands at 13 filings.

Every open-market trade on record is a purchase: 9 purchases worth €120k, and no sale. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Outside the open market, there are 4 share grants. Since January 2025: 3 purchases and no sales on the market.

Half of the purchases are above €9,528 and half below. On 9 out of 9 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. Looking at 6 purchases old enough to measure, the stock rose over the following 90 days in 33% of cases; the median change was -1.0%. These figures describe past trades and do not predict future prices.

The latest filing, published on 11 December 2025, reports an open-market purchase of €21k in Flat Rock Opportunity Fund. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. US insiders must file a Form 4 within two business days of a trade. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
