The world's first pure memory chip ETF recently listed on the US stock market, putting pressure on the world's top three DRAM giants.

Last Thursday, Eastern Time, Roundhill launched the Memory Chip ETF - Roundhill Memory ETF was officially listed on the US stock market, positioned as the market's first "pure memory ETF." According to the announcement, DRAM ETF is an actively managed ETF with a fee rate of 0.65%, investing in a range of memory and storage product manufacturers, currently holding only nine stocks. Only semiconductor companies with more than 50% of their revenue from HBM, DRAM, and NAND can be included. The ETF mainly focuses on the three major DRAM giants worldwide: Micron Technology, Samsung Electronics, and SK Hynix, with a combined weight of over 70%. Its portfolio also includes companies such as SanDisk, Kioxia (formerly Toshiba Memory), Western Digital, Seagate, as well as major memory manufacturers in Taiwan, such as Nanya Technology and Winbond Electronics. As the first ETF in the market dedicated to investing in memory chips, DRAM ETF reflects the current popularity of the memory market. However, many investors are concerned that this ETF may indicate an overheated storage market, possibly serving as a warning "reverse sell indicator" for the bulls.
