Sanan Optoelectronics Co.,Ltd: what insiders have been doing
Headquartered in Xiamen, People's Republic of China, Sanan Optoelectronics Co.,Ltd belongs to the Technology sector and traces its origins to 2000. Filings by its managers are published through SSE / SZSE (CSRC). Between 20 October 2025 and 20 October 2026, 1 insider published 5 filings.
The flow runs one way only: 1 insider bought (5 purchases totalling €8.2M) and nobody sold on the market. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. The largest single trade was a purchase of €1.9M by 林志强, published on 12 June 2026. Among those who bought: 1 board member and 1 chief executive.
For context, the typical company on the same exchange (median of 515 companies) published 2 filings over the same period, against 5 filings here. Our records for Sanan Optoelectronics Co.,Ltd go back to 2022, with 8 purchases and no sales on the open market in total.
The last purchase on record was published on 31 August 2026, which is 50 days ago. 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.
In the same sector, recent insider purchases at Core Scientific, Inc./tx and Gitlab Inc. also feature in our signals. These figures are compiled from regulatory filings published by SSE / SZSE (CSRC). They describe what insiders did and are not a recommendation.
