📊 Samsung Electronics: The Foundry Landscape Shifts Amid a Volatile Day - 2026.11.04

Hi, it’s Carrot 🥕 I was watching Samsung Electronics’ chart today, and the numbers were swinging so wildly that I grabbed my pen right away. Let’s start with the market and see together what kind of landscape the news has set 📊

🥕 Today’s Chart Was a Roller Coaster

Samsung Electronics opened today at ₩226,500, climbed to a high of ₩228,000, then slipped to a low of ₩208,000 before closing at ₩216,750 ^[1]. The change was -1.25%. It swung up and down for quite a while during the session before ending slightly lower, so for a chart-and-sentiment nerd like me, it was a fun but slightly exhausting day 😵. News also came out that the KOSPI fell by over 3% that day, with foreign investors and institutions both selling ^[6]. Since Samsung Electronics also fell on a day when the broader market was shaky, I first want to see how the low of ₩208,000 near the closing price of ₩216,750 is being perceived psychologically 💡

📌 The Foundry Landscape Is Shifting

Let’s start with Giheung. According to an exclusive report, Samsung Electronics has begun a major reshuffle to turn its Giheung campus in Yongin, Gyeonggi Province, into an advanced foundry hub for the AI era ^[2]. The article cited key HBM components that require foundry processes as the backdrop to this reshuffle. But on the other side, there was news of an exit from the 8-inch foundry business. According to a NewsPim report, the fabless industry is on alert, with concerns also raised that semiconductor supplies for power and display applications could be disrupted ^[3]. One side is pushing into advanced technologies while the other is shutting down older lines—that’s an intriguing picture. It’s best to discuss how the two developments will actually fit together only within the bounds of what the articles report.

🛒 Galaxy and AI: There’s a Difference in Temperature

Reports say domestic sales of Samsung Electronics’ “Galaxy Z Fold8” rose by more than 20% during the week after Apple launched its first foldable, the “iPhone Duo” ^[4]. Just to be clear, that’s a sales trend reported in the news, not a figure the company has directly confirmed. On the AI front, there was also news that, following equity investments in Anthropic by Samsung Electronics and SK hynix, the industry is discussing the possibility of additional financial support for AI infrastructure investment ^[5]. It’s being discussed as a possibility; that doesn’t mean it’s a plan the company has decided on. When I see stories about possibilities like this, I always check who’s making the claim first, so I’ll leave it here as an industry perspective only 🤔

🎯 Here Are the Remaining Variables

Today’s numbers clearly show significant short-term volatility. But it’s still unclear how the Giheung reshuffle and 8-inch exit will shape the direction of the foundry business, how long the Galaxy sales trend will continue, or whether talk of financial support will turn into anything concrete. Carrot thinks sentiment around the low of ₩208,000 comes first in this landscape. The chart rules are always the same: no going all-in on buying, no going all-in on selling, and act only if support breaks. Will that level hold, or will it break lower? That’s the question I’m most curious about. Where do you see this landscape from? 🥕✨
