4by4 Inc: what insiders have been doing
Every trade that managers of 4by4 Inc disclose to DART (FSS) is tracked on this page. The company sits in the Technology sector. In the past year (1 November 2025 to 1 November 2026), 9 filings came from 4 insiders.
Purchases and sales both appear in the filings: 5 purchases (3 insiders) and 3 sales (1 insider). The amount is not disclosed for 8 filings. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. On the buying side, the filings list 1 board member, 1 senior executive and 1 chief executive among the declarants.
The clock since the last published purchase (31 March 2026) now reads 224 days. Between a trade and the moment it shows up on DART (FSS), the median delay is 2 days. Until a filing is published, the market cannot know about the trade.
Compared with its exchange (2,655 companies, median 7 filings), a count of 9 filings is above the norm. The full history, which starts in 2022, counts 27 purchases against 8 sales.
In the same sector, recent insider purchases at Basler Aktiengesellschaft and Lime Technologies AB (publ) also feature in our signals. Every figure here comes from the filings published by DART (FSS) and describes the past, not future prices; it is not investment advice.
