QuantumRail Inc.: what insiders have been doing
QuantumRail Inc. belongs to the Technology sector. Filings by its managers are published through DART (FSS). The last twelve months, up to 8 November 2026, brought 17 filings signed by 6 insiders.
On the market, 4 insiders bought (6 purchases totalling €8.1M) while 3 insiders sold (5 sales totalling €6.4M). The amount is not disclosed for 5 filings. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. On the buying side, the filings list 1 major shareholder among the declarants. At €3.5M, the sale published on 10 April 2026 by 하이츠투자조합 is the largest of the period (11.0% of market cap).
For context, the typical company on the same exchange (median of 2,657 companies) published 7 filings over the same period, against 17 filings here. The full history, which starts in 2021, counts 14 purchases against 9 sales.
In all, 2 purchases were made within 30 days of a purchase by another insider of the company. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase. The last insider purchase was made public on 10 June 2026, 153 days ago. Typically, a trade is published a median of 10 days after it takes place. That lag is the time during which only the insider knows about the trade.
