Wang Zheng

Filings by Wang Zheng span 2 companies, the busiest being China Biotech Services Holdings Ltd. and Xinhua Lande Scitech Co., Ltd. - H Shares. Over a trading history stretching from 12 January 2018 to 26 June 2026, the count stands at 10 filings.

On the open market, the record shows 2 purchases and 5 sales. The amount is not disclosed for 7 filings. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket.

The latest filing, published on 28 July 2026, reports a transaction in Xinhua Lande Scitech Co., Ltd. - H Shares. The clock since the last published purchase (22 August 2019) now reads 2,636 days. Typically, a trade is published a median of 2 days after it takes place. This delay matters because a trade only becomes useful information once it is public. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Every figure here comes from the filings published by HKEX and describes the past, not future prices; it is not investment advice.
