Together, these two chipmakers account for more than half of the total market capitalization of the South Korean stock market. Market participants are concerned that the upcycle in memory‑chip prices has peaked, with expectations of a subsequent pullback in pricing and a slowdown in corporate earnings growth.
2nd place$NVIDIA (NVDA.US)$It closed up 0.97%, with trading volume at $18.953 billion.
NVIDIA CEO Jensen Huang is on a high-intensity visit to Europe and will announce an investment plan of over $2 billion in Europe within the next week.
On Tuesday, October 13, Jensen Huang revealed at an event in Paris that the aforementioned $2 billion investment will be announced in stages over the next week. Combined with NVIDIA's $8 billion already invested on the European continent over the past year, its strategic footprint in Europe continues to deepen.
He also announced a new round of funding for the French startups Doctolib, Genesis AI, Pigment, and Entalpic. Following this stop in Paris, Jensen Huang will head to London and Berlin as well.
3rd place$Meta Platforms (META.US)$It closed up 2.63%, with trading volume at $17.202 billion.
Meta is rolling out a suite of AI-powered customization tools on Facebook, enabling users to use natural language to directly tell the algorithm what they'd like to see in their News Feed and Reels. Users can access the new "Your Algorithm" feature via the three-dot menu on posts; after selecting "Interested" or "Not Interested," the system will prompt follow-up questions to gather more granular preference data. Powered by large language models, this feature can recognize and process user intent and contextual cues embedded in free-form text inputs.
In addition, Meta Platforms' stock has risen 35% since September. Pivotal Research has sharply raised its price target for Meta Platforms from $790 to $930, while maintaining a "Buy" rating, implying about 25% upside. Analyst Jeffrey Wlodarczak's core rationale is that Meta's returns on investment in the AI field are "coming into view"—early adoption of the Muse personal AI assistant has been strong, and following the launch of the Muse Wonder model, it has already positioned itself among the industry leaders.

Among them, the HomeView, priced at $299, is the centerpiece of this launch. The device features a 7-inch square touchscreen, supports both tabletop placement and wall mounting, and uses facial recognition to deliver personalized interfaces for up to six household users, curating tailored content based on individual preferences. It integrates Siri AI, calendar management, music playback, and smart-home control into a single device, while emphasizing privacy and data security.
