On July 31, Roundhill Memory ETF rose 5.5% in regular trading, trading at $52.395/share, with turnover of $1.829 billion. The rally was driven by Samsung Electronics' blockbuster Q2 earnings and a sustained memory chip supply-demand tightness outlook.

Samsung Electronics reported Q2 revenue of 171.50 trillion KRW, up 130% year-over-year, with operating profit of 89.49 trillion KRW, surging over 18-fold and significantly beating market expectations. The semiconductor division's profit growth exceeded 250x, powered by robust AI chip demand. Samsung further projected that global memory chip undersupply will persist through 2028 and plans to lock in 60%-70% of its DRAM and NAND capacity via five-year long-term agreements. The company expects server-centric memory demand to remain strong in H2, with HBM and enterprise SSD demand growth accelerating. Kioxia also forecasts further NAND price increases, reinforcing supply tightness across the storage sector.
