김진성

김진성 is a declared insider at 5 companies (senior executive); the most frequent names are 휴럼, 플래티어 and 기아. Between 16 July 2021 and 15 May 2026, the trades on record add up to 13 filings.

Both buying and selling appear: 5 purchases worth €123k, against 1 sale worth €15k. The amount is not disclosed for 1 filing. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. 2026 to date brings 4 purchases and 1 sale.

A typical purchase (the median) is worth €17k. Measured against the company's value, the median purchase equals 0.030% of market capitalisation, across 4 purchases where it is known. On 1 out of 4 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. Ninety days after publication, 4 purchases show a median change of -10.6%, with the price up in 25% of them. These figures describe past trades and do not predict future prices.

Most recently, on 15 May 2026, the filings show a transaction in 휴럼. The latest purchase dates back some time: it was published 164 days ago, on 14 May 2026. The median gap between a trade and its publication by DART (FSS) is 7 days. This delay matters because a trade only becomes useful information once it is public.
