조영식

Filings by 조영식 span 2 companies, the busiest being 에스디바이오센서 and 바이오노트. Over a trading history stretching from 21 July 2021 to 20 August 2026, the count stands at 16 filings.

Both buying and selling appear: 6 purchases worth €3.0M, against 8 sales. The totals do not cover 9 filings with an undisclosed amount. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Since January 2026: 5 purchases and no sales on the market.

The median purchase comes to €207k. Measured against the company's value, the median purchase equals 0.068% of market capitalisation, across 5 purchases where it is known. Of 6 purchases, 1 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. Ninety days after publication, 5 purchases show a median change of -9.6%, with the price up in 0% of them. These figures describe past trades and do not predict future prices.

The latest filing, published on 20 August 2026, reports a transaction in 에스디바이오센서. The most recent open-market purchase was published on 21 April 2026, 180 days ago. Between a trade and the moment it shows up on DART (FSS), the median delay is 6 days. The shorter that gap, the sooner other investors can see what insiders have done. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by DART (FSS) and describes the past, not future prices; it is not investment advice.
