Hong Kong stocks concept tracking | Samsung + Hynix stock prices surge. Korean stock market circuit breaker triggered (with concept stocks).

Last Friday, overnight U.S. storage stocks rose, with Micron Technology, Inc. (MU.US) up over 8%, SanDisk (SNDK.US) up over 7%, Western Digital Corporation (WDC.US) up over 3%, and Seagate Technology Holdings PLC (STX.US) up over 2%. On May 11th, the South Korean stock market futures rose by 5%, and the KOSPI index briefly suspended trading. The South Korean stock exchange initiated the SIDECAR mechanism, suspending KOSPI program trading buy orders. SK Hynix saw the largest intraday increase on the South Korean stock exchange, up by 10%, becoming the stock that had the biggest impact on the rise of the South Korean composite index. Samsung Electronics surged by 6.7%, also hitting a historical record high. The technology-led South Korean composite stock price index has risen by 85% so far this year. Boosted by the record highs of Samsung Electronics and SK Hynix, South Korean semiconductor leaders, A-shares and Hong Kong stock markets have been investing in related funds focusing on the South Korean semiconductor industry, attracting concentrated investor interest, becoming popular investment targets. Among them, the China-South Korea Semiconductor ETF Huatai Bairui is the first A-share ETF that can invest in the South Korean stock market. Due to the scarce QDII quota and the high investment sentiment in the sector, it has continued to trade at a premium, with a year-to-date increase of 98.76%, almost doubling the profit. Micron Technology, Inc. and SanDisk continued their historic rise last week, driven by the simple logic: investment in artificial intelligence infrastructure continues to expand, driving rapid increase in demand for storage chips, while industry supply remains tight. With the combination of strong demand, tight supply, and rising prices, the market is beginning to reevaluate the profit elasticity of storage chip companies.
