Storage concept leading gains, Southern Two Times Long Hailishi (07709) rose 11.48%; Southern Two Times Long Samsung Electronics (07747) rose 3.91%. Public information shows that Southern Two Times Long Hailishi and Southern Two Times Long Samsung Electronics respectively track South Korean semiconductor giants SK Hailishi and Samsung Electronics. Previously, both companies reported record-breaking first quarter performance. As of April 27, SK Hailishi surged more than 7% intraday. In terms of news, recent market media reports suggest that the shortage of memory chips is expected to continue until around 2027. Major manufacturers in the United States and South Korea are expanding DRAM production, but the increased production rate can only cover about 60% of market demand. Counterpoint Research estimates that in order to alleviate the shortage, the industry needs to achieve an annual capacity growth of about 12% by 2027, but the current expansion plans are only about 7.5%. Bank of America Merrill Lynch research report points out that after the first quarter earnings season, the enthusiasm of major storage chip manufacturers to expand HBM production has significantly cooled down, with some of the capital expenditures originally allocated for HBM being transferred to traditional DRAM and even NAND. The bank believes that the investment logic of the storage industry is moving from "AI premium" to "traditional supply shortage". DRAM contract prices reached a historical high in the second quarter of 2026, with 16Gb DDR5 contract prices expected to rise by over 20% sequentially; NAND contract prices are also at historical highs, expected to rise to around $30 in the second quarter. The strong profitability of traditional storage is reshaping the capacity allocation decisions of chip giants.
