South Korea’s stock market is having the kind of year that makes other investors weep into their portfolios. The KOSPI index nearly doubled in the first half of 2026, making it Asia’s best-performing major equity market. Not bad for a country that most people associate with K-pop and really good skincare.
But here’s the thing: the rally has been a bit of a one-trick pony. Samsung Electronics and SK Hynix—both riding the AI chip wave—have basically carried the entire market on their backs. It’s like showing up to a party and realizing 90% of the fun is happening in one room.
Recently, things got bumpy. Sharp swings in chip stocks triggered circuit breakers (the market’s way of saying “everyone chill”), and investors started getting nervous. On Monday alone, the KOSPI opened higher, then reversed course to close down 0.5%. Classic market drama.
So what does Goldman Sachs think? They’re not panicking. In fact, they’re doubling down on their bullish outlook, and they’ve got a pretty compelling reason: the rally is about to spread beyond just the chip guys.
“Earnings momentum is increasingly improving across other sectors,” Goldman’s analysts wrote, pointing to energy, materials, and industrials as the next wave of beneficiaries. Translation: the AI boom isn’t just about memory chips anymore. It’s starting to ripple through the entire economy.
The evidence is already showing up in how money is moving around. Foreign investors are beginning to rotate out of Samsung and SK Hynix and into other AI-related plays and industrial stocks. It’s like watching a crowd slowly realize there are actually multiple rooms at the party.
Now, you might be thinking: “Isn’t this getting speculative?” Fair question. But Goldman says the retail investor positioning doesn’t look like a market that’s about to blow up. Yes, retail activity has picked up, but it’s still well below the levels you’d typically see in an overheated market. The margin-loan numbers that sound scary? Goldman says they’re misleading—a lot of that growth is just from share prices going up, not from people borrowing recklessly.
Here’s the kicker: Korean households are still sitting on massive real estate portfolios and overseas investments (especially US stocks). They haven’t gone all-in on domestic equities yet. That means there’s still a ton of dry powder waiting on the sidelines. If market conditions stay favorable, these households could shift more money into Korean stocks, which would be another fuel source for the rally.
Goldman’s forecasting profits to jump 320% this year and another 35% in 2027. Outside of Samsung and SK Hynix, valuations look reasonable compared to other Asian markets. The bank expects the KOSPI to hit 12,000 over the next 12 months—that’s more than 20% upside from current levels.
Will it be a smooth ride? Probably not. Goldman warns the path will be “bumpy.” But if you’re looking for a market that’s got real earnings growth, room to run, and money still waiting to jump in, South Korea’s looking pretty interesting right now.
