Marta R. Stewart

Marta R. Stewart is a declared insider at 3 companies (board member); the most frequent names are Simon Property Group Inc /DE/, Sherwin Williams Co and Norfolk Southern Corp. In total, 38 filings cover trades dated from 27 January 2016 to 30 September 2026.

No open-market sale appears; the market trades are 22 purchases worth €461k. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The rest of the record consists of 15 share grants and 1 option exercise. In 2026 alone, the filings show 3 purchases and no sales.

The median purchase comes to €21k. Of 22 purchases, 21 formed part of a group of insiders buying within 30 days of each other. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. Looking at 21 purchases old enough to measure, the stock rose over the following 90 days in 76% of cases; the median change was +2.8%. They describe history only and say nothing certain about the share price ahead.

The latest filing, published on 1 October 2026, reports an open-market purchase of €36k in Simon Property Group Inc /DE/. The median gap between a trade and its publication by SEC (Form 4) is 2 days. Section 16 rules allow two business days to file each Form 4. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
