Global investors appear to have treated the washout as an opportunity to rebuild exposure to two companies sitting near the centre of the AI hardware chain.

Korea’s record rebound looks less like a fresh speculative surge and more like the violent reversal of a forced deleveraging event.

Foreign investors bought a net 7 trillion won of Kospi shares while local retail investors sold heavily into the recovery.

The washout may have cleared the weakest leverage, but thinner liquidity means investors should still expect oversized daily swings.
Korea’s AI Rocket Ship Lifts Off Again
South Korean equities did not merely bounce on Friday. They blasted back into orbit.
The surged as much as 17%, its largest advance on record, after losing roughly the same amount over the previous three sessions. SK Hynix briefly approached Korea’s 30% daily trading limit, while Samsung Electronics climbed as much as 26%.
Those numbers sound absurd in isolation, but the rebound makes considerably more sense when viewed through the mechanics of the earlier collapse.
The selloff was never simply a sudden rejection of the AI investment story. Korea had become one of the most concentrated and heavily leveraged expressions of that story. When doubts emerged around hyperscaler debt, capital intensity and potential Chinese competition, the initial decline triggered margin calls, leveraged ETF rebalancing and forced liquidation.
Once that process begins, price stops being an expression of fundamental value and becomes an instruction from the risk manager.
Sell what you can. Reduce gross exposure. Meet the margin call. Ask questions later.
Friday was that machinery moving violently in reverse.
A report that Citadel bought a big chunk of the AI stocks held by hedge fund Situational Awareness also bolstered sentiment that the selloff may near its end. Situational Awareness, which owned shares in a number of Asia-based companies including SK Hynix, has been offloading its holdings after suffering losses in the AI stock rout.
According to Bloomberg, overseas investors purchased a net 7 trillion won of Kospi shares, equivalent to about $4.8 billion. Korean retail investors, by contrast, sold approximately 6.8 trillion won into the recovery.
That divergence is worth watching.
Global investors appear to have treated the washout as an opportunity to rebuild exposure to two companies sitting near the centre of the AI hardware chain. Domestic investors, many of whom had endured the full force of the decline through leveraged products and margin accounts, understandably used the rally to get some risk off the table.
“The market went from throwing AI stocks overboard to fighting for the remaining seats before most traders had finished writing the obituary,” Stephen Innes of SPI Asset Management said in a commentary. South Korea’s Kospi index jumps more than 16% on a surge of chipmaking stocks (Via AP)
I would be careful about interpreting the 17% surge as proof that the entire correction is finished. Markets rarely move cleanly from forced liquidation back into a stable bull trend in a single session. But the rebound does suggest the most disorderly phase of the deleveraging may now be behind us.
The broader AI backdrop also turned supportive at exactly the right moment.
Microsoft’s () spending plans helped restore confidence that the hyperscaler capital-expenditure cycle remains intact. Amazon () reinforced that message after the US close, reporting strong cloud growth and signalling further AI investment. US technology stocks recovered, Taiwan rallied and investors returned quickly to the Asian semiconductor names that had suffered the greatest damage.
That is why I continue to view semiconductors as the purest market expression of the AI buildout.
Software narratives can change quickly. Valuations can be debated endlessly. But when Microsoft, Amazon, and continue pouring capital into data centres, servers and computing capacity, that spending eventually flows into chips, memory, packaging, power infrastructure and cooling systems.
Samsung and SK Hynix sit directly in that spending stream.
Their earnings had remained resilient even while their share prices were being crushed. That was an early warning that the market decline had moved beyond a normal reassessment of profits and into something far more mechanical.
SK Group Chairman Chey Tae-won’s personal purchase of 3,620 SK Hynix shares added a symbolic vote of confidence. The transaction, worth roughly 4.8 billion won, was his first direct open-market investment in the chipmaker.
The purchase itself is far too small to alter the company’s valuation, but markets pay attention when insiders step forward during periods of maximum stress. It tells investors that the people closest to the business do not see the collapse in the share price as confirmation that the underlying franchise has suddenly broken.
The Korean government has also moved to contain the leverage problem.
Authorities introduced higher deposit requirements for leveraged exchange-traded funds linked to Samsung and SK Hynix, following several sessions in which compulsory rebalancing amplified already extreme price moves. Seoul has also pledged approximately $13.9 billion for strategic AI investments through the country’s sovereign wealth fund.
These measures will not eliminate volatility, nor should that be the goal. The more important task is to prevent leverage products from repeatedly turning ordinary market declines into self-reinforcing liquidation events.
The encouraging part of Friday’s rebound is that the speculative foam appears to have been stripped away without destroying the underlying earnings story.
The uncomfortable part is that Korea has now demonstrated how quickly concentrated positioning can overwhelm fundamentals in both directions.
A 17% decline followed by a 17% rebound is not a healthy price-discovery process. It is the signature of a market operating with too much leverage, too little liquidity and too many investors crowded into the same expression.
Still, the AI trade has survived another stress test.
The weakest positions have been flushed, global funds are returning and hyperscaler spending remains pointed higher. That does not mean investors should chase a 20% or 30% daily move in a semiconductor stock. It does mean the burden of proof has shifted back toward those arguing that the AI capital cycle is already rolling over.
My read is that Korea has moved from panic into repair.
The market will remain volatile, and the next stage will probably involve consolidation rather than another straight-line surge. But beneath the leverage, ETF rebalancing and retail capitulation, the core investment argument remains visible.
The AI boom may have lost some speculative excess. It has not yet lost its economic engine.
