Korea's Stock Market Is in a Bear Market — While Still Up 62% This Year

Here's a sentence that shouldn't make sense: South Korea's Kospi index just entered a bear market — and it's still one of the best-performing stock markets in the world this year.

The Kospi opened Tuesday's session down 0.6% at 6,769, putting its drawdown from recent highs past the 25% mark that officially defines a bear market. And yet the index remains up roughly 62% year-to-date. Both things are true at the same time, and the story behind that contradiction is one most North American investors aren't following — even though it directly touches the AI trade sitting inside their index funds.

The AI memory trade is being stress-tested

Korea's 2026 rally was powered almost entirely by one theme: high-bandwidth memory (HBM), the specialized chips that feed data to AI processors. SK Hynix, the country's HBM champion, became the purest way in the world to bet on AI memory demand — and Korean stocks rode that wave to extraordinary heights.

That's exactly why the unwind has been so violent. SK Hynix's American depositary receipts (ADRs) slid 9.3% in the US session following the company's closely watched Nasdaq debut, dragging the entire Korean market down with it. The listing — tied to a planned raise of about US$28 billion to fund capacity and EUV equipment spending — was billed as a test of global appetite for the AI memory trade.

Strategists have been explicit about the stakes. Saxo Markets' chief investment strategist Charu Chanana told Barron's that the ADR listing would reveal whether investors still believe in AI memory or are becoming more selective after the sector's huge rally. The early verdict — a 9%+ slide — suggests selectivity is winning, at least for now.

The next domino: TSMC on July 16

The pressure test continues this week. Taiwan Semiconductor (TSMC) reports earnings and guidance on July 16, and it's arguably the most important data point of the summer for the entire AI complex. TSMC's ADRs slipped nearly 3% recently despite reporting a 36% jump in quarterly revenue — a reminder that when expectations are this high, even great numbers can disappoint.

Citi has an "upside 30-day catalyst watch" on TSMC with a Buy rating, arguing that tight supply in advanced nodes and packaging supports pricing power. UBS raised its target and lifted capex forecasts through 2028. But the caveat both flag is the same: the stock already prices in strong AI demand. July 16 guidance needs to confirm the earnings runway is still expanding, not just intact.

Why this matters for Canadian and US investors

You don't need to own a single Korean stock for this to affect you:

Your index funds are exposed to the same theme. The semiconductor and AI names that dominate the S&P 500 and Nasdaq trade on the same demand signals that just knocked Korea into a bear market. If global investors are becoming pickier about AI hardware, that repricing doesn't stop at the Pacific.

Emerging market and international ETFs hold Korea directly. Popular ex-North America funds carry meaningful Korean weightings, with Samsung and SK Hynix among top holdings. A Kospi bear market shows up in those units even if you never noticed you owned it.

It's a preview of drawdown math. A market can double and still cut an investor in half depending on when they bought. Anyone who piled into the Korean AI trade near the highs is down 25%+ while headline writers celebrate a 62% annual gain. Timing risk is real — one reason a systematic approach like dollar-cost averaging exists. You can model how DCA smooths entry points with our DCA calculator.

What to watch next

• July 16: TSMC earnings and guidance — the AI complex's next verdict.
• SK Hynix ADR trading: whether the Nasdaq listing stabilizes or keeps sliding tells you how much global appetite remains.
• Contagion into US semis: watch whether Korean weakness stays contained or bleeds into the broader chip rally.
