Across 3 purchases, this insider has always bought alone, with no colleague buying within 30 days.
Most recently, on 10 August 2026, the filings show a transaction in 나노신소재. The most recent open-market purchase was published on 26 May 2026, 145 days ago. Filings reach the DART (FSS) feed a median of 7 days after the trade. The shorter that gap, the sooner other investors can see what insiders have done. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
