BYD ELECTRONIC (00285) saw its stock plummet by 5.02% during intraday trading on Friday, as part of a broader decline among Apple concept stocks in the Hong Kong market. The company's shares dropped to HK$41.58, reflecting growing concerns in the smartphone and electronics supply chain sector.

The decline was not isolated to BYD ELECTRONIC, as other Apple suppliers also experienced significant drops. COWELL (01415) fell 5.32%, FIH (02038) dropped 5.05%, and Q TECH (01478) declined 3.33%. This widespread downturn suggests underlying issues affecting the entire Apple supply chain ecosystem.

Several factors may be contributing to this negative trend. Recent reports indicate a 2% year-over-year decline in China's smartphone market sales during the first eight weeks of the third quarter of 2025. Additionally, intensified competition in the mid-to-high-end market and changing consumer preferences are putting pressure on suppliers. Furthermore, OpenAI's recent strategic cooperation agreement with Luxshare Precision, another key player in Apple's supply chain, may be causing uncertainty among investors about the future landscape of the Apple supply ecosystem.
