On-chain analyst Ai Yi said on X that DRAM Memory ETF, described as the first pure-play memory ETF in the U.S. stock market, has added Changxin Technology, also known as CXMT. According to the post, the fund was launched on April 2, 2026 and has assets of $24.55 billion. Its return reportedly peaked at 190% and stood at 161.5% after a pullback in memory stocks. Ai Yi said Samsung, Micron and SK Hynix account for more than 73% of the ETF combined, while CXMT carries a 2.52% weighting. The post also said that after GigaDevice, the ETF has again included a leading A-share memory company. In a separate point, Ai Yi noted that CXMT’s market capitalization has remained above 3 trillion yuan since its STAR Market listing and at one point briefly exceeded 4 trillion yuan. The company is set to leave its no-price-limit trading phase next Monday and move into regular trading.
