On July 30, Roundhill Memory ETF rose 7.67% in regular trading, trading at $48.452/share, with turnover of $891 million.

On the news front, Samsung Electronics released its full Q2 earnings report, posting revenue of 171.50 trillion KRW (+130% YoY) and operating profit of 89.49 trillion KRW (+18x YoY), with net profit exceeding market expectations. The strong results were driven by robust AI-related demand for memory chips, with semiconductor division profits surging over 250x.

Samsung projected that global memory chip supply shortages will persist through 2028, and disclosed plans to lock in 60-70% of total DRAM/NAND output through five-year rolling LTA contracts. The company expects Q3 DRAM and NAND output to grow mid-single-digit and high-single-digit percentages sequentially. TrendForce echoed the tight supply outlook, noting HBM continues to crowd out conventional DRAM capacity. JPMorgan noted that Korean memory sector deleveraging is nearing completion, removing further downside catalysts. Samsung shares surged over 8% on the day, helping reverse the prior session's selloff triggered by SK Hynix's earnings miss.
