孙凯

孙凯 is a declared insider at 4 companies; the most frequent names are 天合光能, 兴业银锡 and 菲利华. Between 21 January 2022 and 31 December 2024, the trades on record add up to 7 filings.

The open-market side counts 5 purchases for €336k alongside 2 sales for €18k. The net balance comes to €318k on the buying side. Unlike grants, an open-market purchase is paid for by the insider, at the market price. 2024 to date brings 4 purchases and no sales.

Half of the purchases are above €48k and half below. Clusters matter here: 1 out of 5 purchases overlapped with buying by a colleague within 30 days. 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 -1.7%, with the price up in 40% of them. They describe history only and say nothing certain about the share price ahead.

Most recently, on 31 December 2024, the filings show an open-market purchase worth €61k in 兴业银锡. Publication is fast: at least half of the trades appear on SSE / SZSE (CSRC) on the same day. This delay matters because a trade only becomes useful information once it is public. Source: insider filings from SSE / SZSE (CSRC). Past trades are no guide to future returns.
