Let’s clear up a huge misconception first.
People always assume value investors only buy cheap, boring, traditional sector stocks—like brick-and-mortar stores or old industrial plays. That’s not true of me.
I look at tech stocks all the time. My rule as an accountant is simple: Every single stock, regardless of its industry, has a price where it makes total sense to buy. Tech is no different.
I’m not blind. I know AI isn’t just hype—it’s a massive wave on par with the Industrial Revolution, and I certainly don’t want to miss out on it. But with the AI craze pushing most US tech stock prices straight to the moon, finding a real bargain feels almost impossible.
I dug deep until I found one that actually fits my strict valuation standards: SK Hynix (listed in South Korea as 000660.KS, NASDAQ ADR Ticker SKHY).
Why buy the primary Korean listing instead of US ADRs? Simple math: The underlying business is identical, the dividend is identical, and the liquidity on the Korean exchange is sky-high. If I can buy the exact same company at a massive discount, why on earth would I pay a premium just because it’s wrapped in a US ticker?
(The US ADR is an alternative only as a last resort for those who physically can’t access foreign markets—and even then, it’s still considerably cheaper than almost any other AI stock out there).
Here is how I am riding the AI train without overpaying for a ticket.
To get why SK Hynix is a rare bargain in today’s tech world, you don’t need a computer science degree. You just need to understand one physical bottleneck in AI servers.
1. What the heck is HBM, and why do AI chips need it?
An Nvidia GPU is like a Bugatti engine. But if you try to feed fuel to that massive engine through a tiny thin drinking straw, the car goes nowhere.
That “drinking straw” problem in AI servers is solved by HBM (High Bandwidth Memory). It’s basically memory chips stacked vertically like a skyscraper. Without HBM, an Nvidia GPU is literally useless.
And guess who is the undisputed king of HBM right now? SK Hynix.
They mastered the manufacturing trick (MR-MUF technology) way before Samsung or Micron. Because of that, they locked up the lion’s share of HBM supply for Nvidia’s flagship GPUs.
2. Why this isn’t your grandfather’s memory stock
Historically, memory makers were treated like cheap commodity sellers with wild price swings. But HBM changes the underlying accounting:
Custom-made, fat profit margins: HBM isn’t something you buy off a shelf. It’s custom-designed, locked in with long-term contracts, and sells at high profit margins.
Sucking up factory capacity: Making HBM takes 3 times more factory capacity than regular RAM. This eats up global memory supply, forcing prices of regular computer memory up across the board!
3. Balance sheet cleanup
Did they carry heavy debt during the last memory slump? Yep. But now? HBM is printing cash for them. They are generating massive cash flow and using it to wipe out debt fast—meaning zero risk of shareholder dilution.
Think about it this way.
During a gold rush, hundreds of thousands of people rush into the mountains trying to hit the jackpot. Most of them go home completely broke. But you know who gets rich every single time? The guy selling the shovels and picks to the miners.
Right now, tech giants (Microsoft, Meta, Google, Amazon) are spending hundreds of billions in a crazy AI arms race.
I don’t care which tech giant wins the AI war. Because no matter who wins, EVERY SINGLE ONE OF THEM has to buy tons of HBM memory from SK Hynix.
Because it’s primarily listed in South Korea, Wall Street constantly ignores it due to the “Korea Discount.” While tourists are paying top dollar for overhyped US AI names, SK Hynix is sitting right there at a price that gives us a true margin of safety.
I don’t hate tech stocks, and I don’t hate growth. I just hate overpaying for a dream that might collapse when market sentiment shifts tomorrow.
Buying SK Hynix isn’t gambling on a promise. It’s owning a real, cash-generating industrial monster that controls the biggest hardware bottleneck on the planet—and buying it at a valuation where I can sleep peacefully at night.
That’s how I participate in the AI revolution: with my eyes wide open, my valuation intact, and my margin of safety firmly locked in.
Disclosure: I hold a long position in SK Hynix (000660.KS) at the time of writing. As a value investor, I run a concentrated portfolio and put my own money where my analysis leads. However, I may buy, sell, or adjust my holdings at any time without prior notice.
