SK Hynix, SanDisk, Western Digital, and Seagate Technology all posted premarket gains exceeding 1%.<\/p>\n<p>As of press time, Dow Jones Industrial Average futures were up 0.11%, Nasdaq 100 Index Futures rose 0.52%, and S&amp;P 500 futures gained 0.21%, with all three major index futures in positive territory, signaling a recovery in investor risk appetite.<\/p>\n<p>Memory chip stocks were the standout performers in premarket trading. In the prior session, the sector had faced broad-based selling, with SanDisk tumbling more than 4% in premarket trading alone, while SK Hynix, Micron Technology, Seagate Technology, and Marvell Technology each fell more than 3%. Today&#8217;s premarket action marked a clear reversal, with SK Hynix, SanDisk, Western Digital, and Seagate Technology all recording gains of over 1%.<\/p>\n<p>The optical communications sector was also active. Applied Optoelectronics rose more than 3% in premarket trading, while Corning, Coherent, and Lumentum each gained over 1%, extending the recent strength in optical networking names.<\/p>\n<p>In Hong Kong, the Hang Seng Index closed marginally lower by 0.02% on Monday, and the Hang Seng Tech Index slipped 0.12%, reflecting an overall muted session. However, semiconductor stocks bucked the downtrend, with Chinese chip designers Montage Technology and GigaDevice, along with Chinese foundry Nexchip Semiconductor, all climbing nearly 5%, emerging as rare bright spots in the Hong Kong market.<\/p>\n<p>From a sector rotation perspective, the swift buying support for memory chip stocks following the previous session&#8217;s sharp pullback suggests that the market&#8217;s medium-term outlook for the sector has not fundamentally shifted due to short-term volatility. The continued strength in optical communications is closely tied to demand for high-speed optical modules driven by AI compute infrastructure buildouts.<\/p>\n<p>Notably, the synchronized strength between U.S. stock futures and Hong Kong-listed semiconductor names indicates that risk appetite across Asia-Pacific and North American markets is converging on the semiconductor supply chain. Investors are closely watching a slate of macroeconomic data due this week, as well as the latest shipment guidance from major memory manufacturers, to gauge the sustainability of the current rebound.<\/p>\n","protected":false},"excerpt":{"rendered":"U.S. stock futures edged higher in premarket trading on Monday, with memory chip stocks staging a broad rebound&hellip;\n","protected":false},"author":2,"featured_media":131346,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[20],"tags":[63829,66968,47031,41976,63831,66969,9463,7021,241,275,10488],"class_list":["post-131345","post","type-post","status-publish","format-standard","has-post-thumbnail","category-sk-hynix","tag-applied-optoelectronics","tag-gigadevice","tag-hang-seng-tech-index","tag-montage-technology","tag-nasdaq-100-index-futures","tag-nexchip-semiconductor","tag-sandisk","tag-seagate-technology","tag-sk","tag-sk-hynix","tag-western-digital"],"_links":{"self":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts\/131345","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/comments?post=131345"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts\/131345\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/media\/131346"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/media?parent=131345"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/categories?post=131345"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/tags?post=131345"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
