QuantaMatrix Inc. Stock: price and insider trades · South Korea

QuantaMatrix Inc. is a Health Care company. Its directors and officers file their transactions with DART (FSS). The last twelve months, up to 2 November 2026, brought 7 filings signed by 4 insiders.

Both sides are active: 2 purchases and 3 sales, from 2 insiders and 3 insiders respectively. The amount is not disclosed for 5 filings. Unlike grants, an open-market purchase is paid for by the insider, at the market price.

The clock since the last published purchase (26 January 2026) now reads 288 days. Between a trade and the moment it shows up on DART (FSS), the median delay is 7 days. This delay matters because a trade only becomes useful information once it is public. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification.

Compared with its exchange (2,655 companies, median 7 filings), a count of 7 filings is typical. The full history, which starts in 2021, counts 3 purchases against 11 sales.

Other companies in the same sector with recent insider buying flagged by our signals: Dynavox Group AB and UCB. These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
