SK Hynix Spurs Rally in Asian Semiconductor Stocks with Mass Production of Advanced AI Chip

/in /tarafından

SK Hynix shares surged by over 9% on Thursday after the South Korean chipmaker announced the mass production of a new high-bandwidth memory (HBM) chip designed for AI applications. The company revealed that the HBM3E chip, the first 12-layer version of its kind, will be ready for delivery by the end of the year. This updated chip boasts a 36 GB capacity, marking a 50% increase from the previous 8-layer version, all while maintaining the same physical thickness.

SK Hynix has positioned itself as a key player in the AI memory chip market, supplying HBM chips to major tech firms like Nvidia. With the new 12-layer HBM3E chip, the company seeks to solidify its dominance in the space, offering advanced solutions for high-end generative AI workloads.

HBM chips are dynamic random access memory (DRAM) components that are stacked vertically, allowing for more compact designs and reduced power consumption. The global HBM market is currently dominated by SK Hynix, Micron Technology, and Samsung Electronics.

Micron Technology also made headlines by issuing better-than-expected revenue and profit forecasts for its fiscal first quarter, citing strong demand for HBM chips. Micron expects $8.7 billion in revenue and profits of $1.74 per share, surpassing market estimates. This positive outlook, coupled with SK Hynix’s announcement, led to a rally in Asian semiconductor stocks.

In Japan, Tokyo Electron’s shares rose 7%, and Advantest climbed 5%, while Samsung Electronics saw a 3% gain. The South Korean Kospi index also responded positively, increasing by 2% as the sector benefitted from these developments.

Asia-Pacific markets advanced on Thursday, with Japan’s Nikkei 225 leading the region and Chinese markets continuing their upward momentum. The Nikkei 225 surged by 2.12%, while the broader Topix rose by 1.65%. The market gains in Japan were buoyed by the release of the Bank of Japan’s July meeting minutes, which provided further clarity on the central bank’s policy stance.

In China, the CSI 300 extended its winning streak to seven consecutive days, hitting its highest level in nearly two months. The rally follows Beijing’s rollout of economic stimulus measures earlier this week. The index opened 0.15% higher on Thursday, signaling continued investor optimism.

Hong Kong’s Hang Seng Index also saw growth, advancing 0.91% to reach its highest point since May. South Korea’s Kospi jumped by 1.9%, with chipmaker SK Hynix surging more than 8% after announcing the mass production of the world’s first 12-layer HBM3E chip, designed for use in artificial intelligence memory applications. The smaller Kosdaq index gained 1.31%.

Australia’s S&P/ASX 200 joined the regional rally, rising 0.53% as markets remained positive.

In contrast, U.S. markets experienced a slight dip. The Dow Jones Industrial Average and the S&P 500 both retreated from their recent record highs. The S&P 500 lost 0.19%, while the Dow fell by 0.7% after reaching a new high during early trading. Meanwhile, the Nasdaq Composite edged up marginally by 0.04%, remaining in positive territory despite the broader decline.

 

Asian Chip Stocks Plummet Following Nvidia’s Wall Street Sell-off Amid Antitrust Probe Concerns

Asian semiconductor stocks faced significant declines on Wednesday after Nvidia’s sharp 9% drop on Wall Street overnight. This followed concerns about the U.S. economy and an antitrust investigation involving Nvidia. The sell-off hit major players across Asia, with SK Hynix falling over 6%, Samsung Electronics down 2.6%, and TSMC dropping 4.3%. Japan’s Tokyo Electron and Advantest also suffered heavy losses, reflecting the broader impact of Nvidia’s slump, which erased $279 billion from its market cap. The downturn highlights the global ripple effect of Nvidia’s performance in the semiconductor sector.
