Hello, World.

 Welcome to my blog. I am a financial journalist based in South Korea with years of experience covering the heartbeat of the Korean economy—including banking, financial holding companies, insurance, credit cards, foreign exchange markets, and monetary policy.


​About a year ago, I transitioned to the Securities Department. Since then, I have been analyzing major stocks on the KOSPI, KOSDAQ, and U.S. stock markets, with a particular focus on the intricate interconnections between these two markets.
​I created this blog to share insightful, real-time analysis of the South Korean market with a global audience.

​I’ll start with the essentials—broken down simply. We’ll explore why Samsung Electronics and SK Hynix stock prices are surging, why memory semiconductors are currently in the spotlight, and how the memory cycle flows down to materials, components, and equipment (Sojangbu) companies.

​Moving forward, I will also dive into the mechanisms of diverse sectors, including Defense, Secondary Batteries (EV batteries), Bio-Pharma, Construction, and the Banking/Securities industries. Over time, I plan to expand into personal finance topics that I am deeply passionate about, such as Bitcoin, insurance, and real estate.

​A quick note: As English is not my first language, I use Generative AI to assist with translations. I appreciate your understanding as I strive to bridge the language gap to share professional insights from Seoul.
​Thank you for joining me on this journey. :)

​[Industry Introduction for Stock Beginners] Samsung Electronics & SK Hynix: Understand Why They’re Surging Before You Invest

​Samsung Electronics and SK Hynix account for 40% of the total market capitalization of the KOSPI. Over the past year, their stock prices have skyrocketed by 303.85% and 574%, respectively. You’ve probably heard that this is "thanks to the AI Super-Cycle." However, surprisingly few people understand exactly what that means or why it has driven these stock prices so high. It’s actually quite simple. Just keep this structure in mind: ​'Samsung/Hynix → NVIDIA → Microsoft/Meta/Google/Amazon' ​1. The Top of the AI Cycle: Microsoft, Meta, Google, and Amazon ​We are living in an era where everyone uses AI. To use AI, a massive amount of computation and data processing is required. When you send a request to ChatGPT, your smartphone doesn't process it directly. Your request travels through the internet to a massive "computer factory" called an AI Data Center located somewhere in the world. The giant servers in that factory handle the complex calculations and rec...

Semiconductors Aren’t Made Alone… “Materials, Parts, and Equipment” Are Essential. ① Who Are the Representative Equipment Companies?

Let’s review what we covered last time. HBM (High Bandwidth Memory) made by Samsung Electronics and SK hynix goes into Nvidia’s AI GPUs. Nvidia’s AI GPUs are needed in hyperscalers’ data centers. As hyperscalers increase their investment in AI, demand for HBM from Samsung Electronics and SK hynix rises, and both companies’ earnings grow. In other words, the memory semiconductor supercycle follows the structure of “Samsung Electronics · SK hynix → Nvidia → hyperscalers.” But beneath Samsung Electronics and SK hynix, there are numerous other companies connected. These are the so-called “materials, parts, and equipment” companies, or “MPE (SoBuJang in Korean).” They supply the materials, parts, and equipment needed to produce HBM. Let’s look at an example. As mentioned before, HBM is made by stacking multiple DRAM chips. Obviously, you can’t just stack DRAM like Lego blocks and call it HBM. You need to press them together using equipment called a “bonder” (Bonder comes from the word “bon...

The Prince of Land Warfare, Hyundai Rotem's 'K-2'

이미지
 Now, lastly, we have Hyundai Rotem. Hyundai Rotem operates in a slightly different territory compared to LIG D&A, KAI, and Korean Air, which I introduced in previous posts. While those three specialize in aerial warfare like missiles and fighter jets, Hyundai Rotem's main focus is the tank—the prince of land warfare. Their flagship lineup includes the K-2 Black Panther main battle tank, wheeled armored vehicles, obstacle-clearing tanks, K1/K1A1 tanks, and armored recovery/bridge vehicles. As you might have guessed, tanks have historically garnered more spotlight in the Russia-Ukraine war than in Middle Eastern conflicts. This means their main customers have been European nations. Recently, however, that pattern has been changing a bit. It appears they are set to diversify their export destinations beyond Europe and into the Middle East. Earlier, I explained that Middle Eastern warfare primarily revolves around fighter jets and airstrikes. But there is one blind spot to this: y...
