Bosera Fund issued a risk warning and suspension/restart announcement last night regarding the Bosera ChiNext Composite ETF. The announcement stated that recently, the trading price of the ETF (ticker: 159287) in the secondary market had experienced a significant premium, deviating markedly from its net asset value. Investors are warned to be aware of the risks of trading price premiums, and blind investment could lead to substantial losses.

The announcement further explained that the fund manager reminds investors that, besides the risk of net asset value fluctuations, the ETF’s secondary market trading price can be affected by market supply and demand, systemic risks, liquidity risks, and other factors, which may result in losses. As of now, the fund is operating normally without any undisclosed material information. The fund manager will strictly adhere to laws, regulations, and the fund contract to conduct investment operations and fulfill disclosure obligations.

Hong Kong stocks perform relatively sluggish

The Hong Kong stock market showed a relatively subdued performance this morning. Among Hang Seng Index components, Zhongtong Express-W led the gains, rising over 6% intraday.

Zhongtong Express released its earnings report, indicating that despite fierce industry competition in 2025, the company continued to improve operational efficiency and focus on profit growth, resulting in steady financial and operational performance. Revenue increased by 10.9% year-over-year from RMB 44.281 billion as of December 31, 2024, to RMB 49.099 billion in 2025, mainly driven by increased online consumption penetration and a shift toward higher-value customer segments, boosting express demand.

However, in freight forwarding services, Zhongtong Express provides freight forwarding through the acquisition of China Eastern Express Co., Ltd. (a major freight forwarder and international logistics provider in Hong Kong and Shenzhen). Revenue from this segment decreased by 8.7% compared to 2024, mainly due to declining cross-border e-commerce pricing.

The Hang Seng Tech Index was mostly down during the morning trading session. Among its constituents, Kingdee International, Bilibili-W, and Huahong Semiconductor led the gains; Tencent Music-SW, Li Auto-W, Xpeng Motors-W, and Leap Motor declined during the session.
