📊 Samsung Electronics: Tech Competition and Diverging Investor Flows - 2026.10.14

Hi, it's Goguma 🍠 The key thing today is that the news about tech competition and the stock's movement are pointing in different directions. Let's unpack it step by step.

Tech Competition: Are They Headed the Same Way?

After China's CXMT unveiled its '4F²' technology, Samsung Electronics President Song Jae-hyuk said at SEDEX 2026 that Samsung is also developing the same technology ^[1]. The mood at the event could be summed up in one line: 'We're working hard on development too' ^[2]. CXMT reportedly announced plans to launch next-generation server DRAM using its new 4F² technology within the year ^[1].

The question is whether the announced launch will translate into actual mass production and market share. The information available doesn't answer that, so I won't jump to conclusions.

Why Are Investor Flows Diverging?

The market reaction was quite rough. Foreign investors recorded net selling of more than 4,500,000,000,000 KRW in just one day, and reports said Samsung Electronics and SK hynix both fell sharply ^[3]. According to the price table, the closing price on October 13 was ₩234,000, with a change of -6.77%. Japan and Taiwan also faced semiconductor jitters, but the point that South Korea's market was hit harder is worth noting ^[3].

That said, these are investor-flow facts reported by the news. I don't think it's reasonable to pin the cause on a single factor.

Customer-Side Factors and Product Prices

Supplies of RAM for smartphones are reportedly shrinking while prices are rising ^[4]. Meanwhile, on the 1st of this month, Samsung Electronics raised the domestic retail prices of the Galaxy S26 series, just 7 months after launch. The 256GB base model went up by about 150,000 KRW, and the 1TB Ultra by about 270,000 KRW ^[4].

Curious who wins and who loses when RAM prices rise? The information alone isn't enough to gauge the impact on earnings.

Meanwhile, Samsung Electronics introduced its 'AI Modular Home' to Climate Minister Kim Seong-hwan and said it would take the lead in electrifying heating ^[6]. The report also noted that the government is exploring ways to use high-efficiency, low-carbon housing solutions ^[6]. It may seem far removed from semiconductors, but it's an interesting example of business diversification.

Ownership Changes and Four Perspectives

Hong Ra-hee, honorary director of the Leeum Museum of Art, is gifting Samsung Electronics shares worth about 2,600,000,000,000 KRW to her son, Chairman Lee Jae-yong ^[5]. Once the gift is complete, Chairman Lee's stake is expected to rise from 1.58% to 1.75% ^[5]. The share transfer is a confirmed fact, but the information doesn't tell us what it means for the stock price.

Here's how I, Goguma, would sum up the four perspectives. The materials today don't present four separate viewpoints, though, so I've distinguished confirmed facts from my own interpretation. In my view, the key point is that tech news and a shock to investor flows are playing out on the same stage. Technology is moving ahead with the message 'in development,' while investor flows are speaking first through the numbers on foreign net selling. That's why I see both bullish and bearish scenarios coexisting.

There are two questions for this week: Will the 4F² competition lead to actual shipments and earnings, and how long will the outflow of investor funds last? Neither answer is in the information available yet.
