🍠 Samsung Electro-Mechanics: A Day of Conflicting AI Hopes and a Share Price Reversal - 2026.10.16

Hi, it’s Goguma. Today, let’s take our time looking at why Samsung Electro-Mechanics’ share price turned lower and how far AI optimism might go. 🍠

What was behind the share price reversal in a single day?

On the 15th, Samsung Electro-Mechanics moved the most among the top market-cap stocks on the KOSPI ^[1]. The article cited “concerns over the staying power of AI investment” as the reason for the decline, while the KOSPI also fell to close around the 5550 level. According to the table, the closing price on the 15th was ₩1,122,000, and the change was -18.52% ^[1]. The amounts and percentages in the article text don’t match the table, so I’ll leave those out and use only the table figures here. The following day, the 16th, the stock recorded +1.38% at ₩1,179,000, showing signs of catching its breath.

Whose outlook is the third-quarter earnings forecast?

Money Today reported expectations that third-quarter operating profit could rise substantially, saying demand for MLCCs used in AI servers would benefit Samsung Electro-Mechanics’ results ^[2]. Another outlet offered a similar outlook, citing growing demand for AI server MLCCs and FC-BGAs ^[3]. The important point is that these are forecasts from analysts and the media. They are neither confirmed earnings figures from the company nor claims that the company itself made, based on the available material. So I’ll treat this only as a conditional scenario—something that could happen. Earnings aren’t like a signed contract; expectations don’t turn straight into numbers. 🤝

What’s happening on the next-generation substrate front?

In the glass substrate business, there’s news that joint venture “Glasem” has started recruiting experienced employees ^[4]. A separate report also named suppliers of glass substrate equipment ^[5]. Hiring people and building an equipment supply chain can be read as signs that the business is moving beyond the preparation stage. However, the materials don’t give production scale or timing, so “when will it ramp up in earnest?” remains an open question. In Sejong’s Myeonghak Industrial Complex, news followed Samsung Electro-Mechanics’ announcement of a large-scale investment: SK Trichem is also set to invest ^[6]. Since the article text couldn’t be verified, I’ll leave the investment details there. 🎯

Bullish and bearish scenarios are both in play

The bullish case centers on demand for AI server components and the expanding supply chain. One article says a fund with strong returns holds Samsung Electro-Mechanics and Samsung SDI, and that its portfolio manager sees the AI investment cycle spreading sequentially through the supply chain ^[7]. The bearish case is the concern over the staying power of AI investment that drove the sharp share price drop on the 15th. Video content noted that orders had piled up, yet the share price moved in the opposite direction ^[8]. Since this is also a claim made in a video, I’ll leave out the figures and note only the general direction. My personal take, as Goguma, is that the biggest question is how the third-quarter outlook and the recent share price trend are pointing in opposite directions. With the information available now, we can’t tell who has read this gap correctly. I’ll leave the unresolved disagreement as it is.

To sum up, there are two key variables in this round: whether expectations for AI server component demand translate into actual production and earnings, and how concerns over the staying power of AI investment will play out. Which one do you think will provide an answer first?
