张斌

张斌, listed as senior executive, has filed trades across 3 companies (mainly through SSE / SZSE (CSRC)), most often in 和辉光电, 芳源股份 and 中科电气. We count 7 filings; the first trade dates from 28 April 2022 and the latest from 18 August 2025.

In open-market terms, that means 5 purchases worth €94k on one side and 2 sales worth €102k on the other. On balance, insiders were net sellers of €7,870. Unlike grants, an open-market purchase is paid for by the insider, at the market price. In 2025 alone, the filings show no purchases and 2 sales.

The median purchase comes to €16k. None of the 5 purchases we analysed coincided with buying by another insider of the same company within 30 days. Looking at 5 purchases old enough to measure, the stock rose over the following 90 days in 20% of cases; the median change was -8.4%. Past outcomes like these are no guarantee of what comes next.

The latest filing, published on 18 August 2025, reports an open-market sale of €21k in 和辉光电. The clock since the last published purchase (30 April 2024) now reads 909 days. Half of the filings or more reach the SSE / SZSE (CSRC) feed on the day of the trade. The shorter that gap, the sooner other investors can see what insiders have done. Every figure here comes from the filings published by SSE / SZSE (CSRC) and describes the past, not future prices; it is not investment advice.
