Storage concepts led the gains, Southern double-long Hailishi (07709) rose by 11.48%; Southern double-long Samsung Electronics (07747) rose by 3.91%. Public information shows that Southern Double Long Hailishi and Southern Double Long Samsung Electronics track South Korean semiconductor giants SK Hailishi and Samsung Electronics, respectively. Previously, both companies reported record-breaking first quarter earnings. As of April 27th, SK Hailishi surged over 7% intraday. On the news front, recent reports from market media suggest that the shortage of memory chips is expected to continue until around 2027. Major manufacturers in the US and South Korea are expanding DRAM production, but the increase in production capacity can only cover about 60% of market demand. According to Counterpoint Research, in order to alleviate the shortage, the industry needs to achieve an annual capacity growth of about 12% by 2027, but current expansion plans only amount to about 7.5%. A Bank of America Merrill Lynch research report pointed 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 expenditure originally allocated to HBM being shifted to traditional DRAM and even NAND. The bank believes that the investment logic in the storage industry is shifting from "AI premium" to "traditional supply shortage". DDR5 contract prices for 16Gb have reached a historical new high in the second quarter of 2026, with an expected further increase of over 20%; NAND contract prices are also at historical highs, expected to rise to around $30 in the second quarter. The super-profitability of traditional storage is reshaping the capacity allocation decisions of chip giants.
