Even slight market declines can easily trigger massive passive selling waves, exacerbating panic in the market. ▪ Overseas supply chain disruptions: The Samsung Electronics union plans an 18-day strike over wage issues, raising market concerns about short-term fluctuations in the global supply of memory chips, leading to sharp declines in related overseas leveraged ETFs. **Top 10 Market Turnover** ▪ SMIC (00981.HK) Last traded at HK$71.45, down 0.07%, with turnover of HK$11.4 billion ▪ Alibaba-W (09988.HK) Last traded at HK$132.40, down 3.99%, with turnover of HK$11.2 billion ▪ Tencent Holdings (00700.HK) Last traded at HK$455.40, up 0.11%, with turnover of HK$11.0 billion ▪ CSOP 2x Long SK Hynix (07709.HK) Last traded at HK$91.48, down 12.88%, with turnover of HK$10.3 billion ▪ Hua Hong Semiconductor (01347.HK) Last traded at HK$115.50, down 9.06%, with turnover of HK$6.9 billion ▪ Yangtze Optical Fibre and Cable (06869.HK) Last traded at HK$222.60, down 12.29%, with turnover of HK$4.9 billion ▪ Xiaomi Group-W (01810.HK) Last traded at HK$30.70, down 3.22%, with turnover of HK$4.4 billion ▪ Montage Technology (06809.HK) Last traded at HK$449.20, down 6.88%, with turnover of HK$3.4 billion ▪ Meituan-W (03690.HK) Last traded at HK$82.65, down 3.56%, with turnover of HK$3.1 billion ▪ Kingboard Laminates (01888.HK) Last traded at HK$41.88, down 7.39%, with turnover of HK$2.7 billion ### Related Stocks -
