AI Fatigue Hits Korea: Tech Bets Unwind as Foreign Money Flees and Volatility Creeps In

The AI trade that everyone loved is starting to look a little less inevitable, and nowhere is that more obvious than in Seoul. Korean stocks, once the darling of global tech momentum, are suddenly under pressure as investors pull back from artificial intelligence bets. The narrative that chips and bots would save us all is running into the reality of crowded trades and a macro backdrop that’s turning less forgiving by the day. If you thought the AI unwind was just a Nasdaq story, think again. Korea is where the rubber meets the road.

Jensen Huang, the face of Nvidia and the unofficial mascot of the AI boom, was in Seoul last week, but the market didn’t care. South Korean stocks plunged as investors yanked capital from the same chipmakers and hardware names that were supposed to be the backbone of the next industrial revolution. The KOSPI, which had outperformed global peers for most of 2025, is now lagging as foreign outflows accelerate. The story isn’t just about price action. It’s about a fundamental shift in risk appetite, and the realization that not every AI bet is going to pay off.

Let’s talk numbers. The KOSPI is down nearly 7% from its May highs, with chipmakers leading the retreat. SK Hynix, Samsung Electronics, and a host of smaller AI hardware plays have seen double-digit drawdowns in the past two weeks. Foreign investors, who poured more than $14 billion into Korean equities in 2025, have turned net sellers for the first time in 18 months. The unwind is happening fast, and the pain is real. According to YouTube financial news, the selloff accelerated last week as global funds rotated out of Asia’s AI proxies and back into defensive sectors in the US and Europe.

The timing couldn’t be worse. The S&P 500 just logged a 2.6% weekly drop, the Nasdaq is wobbling, and the new Fed chair is making noises about keeping rates higher for longer. Liquidity is drying up, and the risk-on trade that powered everything from Nvidia to Korean memory stocks is starting to look tired. If you’re a global macro trader, this is the canary in the coal mine. When the most crowded trades start to unwind, the dominoes can fall quickly.

The broader context is even more telling. Korea’s equity market has always been a high-beta play on global tech cycles, but the current unwind feels different. The AI trade was supposed to be secular, immune to macro headwinds. But when everyone is long the same names, even a small shift in sentiment can trigger a cascade. The KOSPI’s correlation with the Nasdaq has surged to a five-year high, and volatility is creeping higher. The V-KOSPI, Korea’s volatility index, is up 22% in the past month, a sign that traders are finally waking up to the risks.

This isn’t just about Korea. The AI unwind is global, and the pain is spreading. European tech names are underperforming, and US chipmakers are suddenly looking vulnerable. The narrative that AI would be a one-way ticket to riches is colliding with the reality of crowded positioning and a macro backdrop that’s getting tougher by the day. The unwind in Korea is a warning shot for anyone still clinging to the AI trade.

The technicals are confirming the shift. The KOSPI has broken below its 200-day moving average for the first time since 2024, and momentum indicators are rolling over. The selloff in chipmakers is especially acute, with SK Hynix down 13% in two weeks and Samsung Electronics off 9%. Foreign outflows are accelerating, and local funds aren’t stepping in to catch the falling knife. The market is in risk-off mode, and the path of least resistance is lower.

Strykr Watch

The key level for the KOSPI is 2,550. That’s the line in the sand, and a break below it could trigger another wave of selling. The 200-day moving average sits at 2,570, and the index is currently flirting with that level. If the KOSPI can reclaim 2,600, the worst might be over, but the technicals are not encouraging. The V-KOSPI is at 23, up from 18 a month ago, and the 14-day RSI is sitting at 39, deep in bearish territory. Chipmakers are the epicenter of the pain, with SK Hynix testing support at KRW 120,000 and Samsung Electronics at KRW 65,000. If those levels break, the unwind could accelerate.

Foreign flows are the wildcard. If global funds continue to rotate out of Korea, the selling pressure will intensify. But if the market can stabilize and attract bargain hunters, there’s a chance for a short-term bounce. The options market is pricing in higher volatility, with skew favoring downside puts. That’s a sign that traders are bracing for more pain.

The macro backdrop is not helping. The Fed is signaling higher for longer, and global liquidity is tightening. That’s not a recipe for a quick recovery. The best hope for bulls is a stabilization in US tech and a reversal in foreign flows. Until then, the risk is to the downside.

The opportunity here is for traders who can time the bounce. The selloff has been sharp, and oversold conditions are starting to emerge. But catching falling knives is a dangerous game, and the safer play is to wait for confirmation of a bottom. If the KOSPI can reclaim 2,600 and chipmakers hold key support, there’s a chance for a relief rally. But the trend is still down, and caution is warranted.

Strykr Take

The AI unwind is real, and Korea is ground zero. The crowded trade is unwinding, and the pain isn’t over. The technicals are bearish, foreign flows are negative, and the macro backdrop is hostile. The opportunity is for traders who can time the bounce, but the risk is to the downside. Stay nimble, watch the levels, and don’t get caught on the wrong side of the unwind.
