A sell-off in AI and semiconductor stocks hit Asia again today, repeating a pattern that has become familiar in recent weeks. Following Wednesday's sharp decline on Wall Street, Samsung Electronics and SK Hynix suffered heavy losses in the Asian session on Thursday morning, with Samsung falling more than seven percent at the open and SK Hynix dropping over nine percent. SK Square, the largest shareholder of SK Hynix, also closed down nearly thirteen percent, reflecting the broad-based losses in the sector.

The trigger for this latest wave came directly from the US. Micron Technology shares fell more than ten percent in Wednesday's session, despite the company having recorded an incredible two hundred and sixty percent rise since the beginning of the year. Sandisk also experienced a similar loss in overnight trading. This is just the latest in a scenario that has repeated itself repeatedly throughout June, when a similar wave of chip selling caused Kospi to lose more than eleven percent of its value in a single day, triggering circuit breakers and halting trading for twenty minutes.

The real concern is that this selling pressure is no longer tied to a single day or a single piece of news. Since the second half of June, chip stocks have repeatedly entered a cycle of sharp declines and partial recoveries, each time retreating again without surpassing the previous peak. Several separate but interconnected factors are behind this. First, interest rate expectations; under the new Fed chairman Kevin Warsh, the market now expects twice as many rate hikes by the end of the year as previously priced in, raising questions about the sustainability of debt-financed AI infrastructure spending. Second, valuation concerns from within the sector itself; chip stocks have risen so sharply since the beginning of the year that the market has now shifted from asking "how much further can it rise?" to "is it overheating?"

The South Korean market is particularly vulnerable to such shocks, as Samsung and SK Hynix alone account for roughly half of Kospi's total market capitalization. This concentration means that any disruption in these two companies instantly impacts the entire index, much like pulling out the bottom blocks of a Jenga tower. A similar picture emerges in Japan, where SoftBank remains under pressure, partly due to weakness in chip designer Arm Holdings, and further fueled by news that OpenAI may postpone its IPO until next year, limiting investor appetite for SoftBank.

However, it would be wrong to interpret the picture entirely pessimistically. Earlier this week, the South Korean government announced that Samsung and SK Hynix will jointly invest in a national semiconductor ecosystem project worth eight hundred trillion won. SK Hynix will also begin trading on Nasdaq with American Depositary Receipts on July 10th, demonstrating that its long-term growth story is still alive. So the current situation is being interpreted less as a fundamental collapse and more as a revaluation reset for an overly rapid rise in the sector, not stemming from a recession or geopolitical crisis.

For those following both the stock and crypto markets through Gate, the crucial point is that this concentration risk in the semiconductor sector has now become a global sensitivity affecting not only American indices but also much of Asia simultaneously. In the coming days, Micron's quarterly results and signals regarding the Fed's interest rate path will be the most critical data points to clarify whether this sell-off is a correction or a longer-term trend reversal.
