United Microelectronics Corp: what insiders have been doing
United Microelectronics Corp, classified in the Technology sector, is a listed company based in Hsinchu City, Taiwan, founded in 1980. Its insiders report their share dealings to SEC (Form 4). In the past year (22 October 2025 to 22 October 2026), 7 filings came from 3 insiders.
All open-market trades in the period are sales: 5 sales worth €459.8M, by 3 insiders, with no purchase on record. Biggest ticket of the year: €258.2M, sold by Liu Chitung and made public on 13 July 2026 (0.49% of market cap).
Compared with its exchange (2,023 companies, median 41 filings), a count of 7 filings is below the norm. Over the whole record (from 2026), the tally stands at no purchases and 5 sales.
Typically, a trade is published a median of 1 day 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.
