Memory Chip Stocks Soar on SK Hynix Rally; Powerchip Hits Limit

Shares of memory chip manufacturers surged on July 15, 2026, following a dramatic 27% rise in SK Hynix's American Depositary Receipts (ADRs) the previous day. This rally propelled Taiwan's Powerchip Semiconductor (PSC) to its trading limit, reaching NT$180.5.

Market analysts anticipate continued growth for PSC, a key supplier of SLC NAND chips. A recent report from TrendForce highlights a severe shortage of MLC NAND chips due to production capacity being diverted to higher-value 3D NAND products. This scarcity, coupled with increasing demand for SLC NAND from industrial, automotive, and networking sectors, is expected to drive contract prices up by 120% to 170% in the second half of 2026. PSC's strong position in the SLC NAND market positions it for significant operational expansion.

Powerchip Semiconductor demonstrated robust financial performance, reporting consolidated revenue of NT$20.597 billion in June, a 2.98% increase from May and a substantial 189.88% jump year-over-year. The company's second-quarter revenue reached NT$59.843 billion, up 56.45% from the previous quarter and 184.7% year-over-year. For the first half of 2026, PSC's cumulative revenue stood at NT$98.096 billion, marking a 139.2% increase compared to the same period last year. These figures represent new records for June, the second quarter, and the first half of the year.
