SK Hynix Drops 5% After Approving $38B in New Memory Fabs; Seagate Falls 7%, Micron Barely Dips

Key Points:

• SK Hynix’s board approved a $38 billion investment to build two new memory fabs in South Korea, focusing mainly on DRAM capacity to meet AI-driven demand, but shares fell 5% amid concerns over the large capital outlay and deferred shareholder-return updates.
• The broader memory sector showed mixed performance, with Seagate Technology down 7% likely due to profit-taking after a strong year-to-date run, while Micron Technology and SanDisk experienced smaller declines despite solid earnings reports.
• SK Hynix aims to complete four Yongin fabs by 2033, accelerating its timeline amid expectations of a severe memory shortage in 2027, which management views as a structural shift driven by AI demand rather than a cyclical trend.
• The Roundhill Memory ETF, heavily concentrated in Samsung, SK Hynix, and Micron, declined 2%, reflecting uneven profit-taking across memory stocks rather than a fundamental sector downturn.
• Investors should watch for SK Hynix’s upcoming Q3 shareholder-return update and Micron’s September earnings, as these could influence market sentiment regarding potential oversupply and the sector’s pricing power going forward.
