Dr. Olaf Stiller

Dr. Olaf Stiller is a declared insider of NanoRepro AG, with filings sourced from BaFin. Between 16 May 2025 and 17 August 2026, the trades on record add up to 9 filings.

Every open-market trade on record is a purchase: 9 purchases worth €91k, and no sale. Unlike grants, an open-market purchase is paid for by the insider, at the market price. 2026 to date brings 8 purchases and no sales.

In size, the median ticket on the buying side is €9,997. Relative to company size, the median is 0.040% of market cap (8 purchases with a known value). Of 8 purchases, 2 formed part of a group of insiders buying within 30 days of each other. Purchases made close together by different insiders form what is called a cluster. For 6 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 50% of cases, with a median move of +0.5%. Past outcomes like these are no guarantee of what comes next.

The latest filing, published on 18 August 2026, reports an open-market purchase of €5,000 in NanoRepro AG. The median gap between a trade and its publication by BaFin is 3 days. For comparison, MAR article 19 gives managers three business days to notify a trade. Every figure here comes from the filings published by BaFin and describes the past, not future prices; it is not investment advice.
