🥕 Hyundai Mobis Is Expanding Its Automotive Chip Business—but Is the Stock Still Stuck in a Range? - 2026.10.21

Hi, it’s me, 🥕 Carrot! Let’s start today with automotive semiconductors. Hyundai Mobis announced that it has begun developing 13 automotive system semiconductors ^[1]. Since this is about taking direct responsibility for the chips that go into cars, it’s an issue worth paying attention to. 📊

The push to localize chips is gathering momentum

Hyundai Mobis is speeding up efforts to localize automotive semiconductors in partnership with domestic companies ^[1]. It might sound like a low-key story about components, but in reality, it ties into a broader shift across the auto industry as companies rebuild their supply chains. One article noted concerns that the chip shortage from three years ago could happen again ^[2]. But then again, we all remember cars being unable to roll off the line because there weren’t enough chips. That’s why automakers’ efforts to bring semiconductor production in-house seem to stand out even more.

The key point from Hyundai Mobis is that it’s combining in-house design with partnerships with outside foundries ^[2]. It already produces several types, and it also mentioned next-generation plans such as network system-on-chips (SoCs) ^[2]. On top of that, a “Automotive Semiconductor One Team TF” has been launched, bringing together SK Key Foundry, four small and medium-sized fabless companies, and four support organizations ^[3]. The playing field is clearly expanding, but no one can say for sure yet how quickly that will pay off.

Keep an eye on the year 2029

The Electronic Times reported that Hyundai Mobis CEO Lee Gyu-seok said domestically made automotive semiconductors would be installed for the first time in 2029, with the aim of building a self-sustaining ecosystem ^[4]. Since an executive has directly named a target year, it looks to me like a clue to the direction of the semiconductor strategy. Still, this is only the CEO’s statement, and the article doesn’t say more about which products will be installed or how. What I’m curious about is how quickly the collaboration task force will move between now and 2029. 🎯

The global ranking is steady, but the stock has been on a roller coaster lately

There’s also news about the global ranking of auto parts suppliers. According to the Korea Automotive Technology Institute’s analysis of the world’s top 100 parts suppliers, Hyundai Mobis has held on to No. 6 for three consecutive years ^[5]. Daehan Economic Daily also reported the same ranking, noting that China’s CATL came in at No. 3 ^[6]. Since this ranking comes from a third-party analysis and isn’t a plan announced directly by the company, it’s probably best to take it as a measure of consistency. Wow, three years in a row is pretty consistent ✨

The chart tells a slightly different story. The closing price on October 21 was ₩345,000 and the change was -0.86%, with trading volume at 254,088. The previous day’s closing price was ₩345,500 and the change was -5.08%. Today’s high was ₩351,000, and low was ₩340,000, so that’s the range we’re watching right now 📊. Looking only at the chart, Carrot thinks the stock is still catching its breath in this range. No going all-in on buying, no going all-in on selling, and only act if support breaks—that’s my rule. So the first thing to watch is whether the ₩340,000 low gets breached.

But one question remains: How will semiconductor investment, the 2029 target, and a steady ranking come together while the stock stays in its range? There’s no answer yet, so it’s worth watching a little longer 🥕
