South Korea’s stock market staged a strong comeback Wednesday after suffering one of its sharpest declines of the year, as investors cautiously returned to technology shares ahead of a closely watched earnings report from Micron Technology.

The Kospi rose more than 3%, recovering part of the previous session’s steep losses after a global semiconductor selloff rattled markets across Asia, Europe, and the United States.

Leading the rebound were South Korea’s technology giants.

Samsung Electronics climbed more than 8%, while memory-chip maker SK Hynix gained roughly 3%, helping lift the broader market after both companies were heavily sold during Tuesday’s rout.

The recovery helped stabilize investor sentiment following a difficult day for technology stocks worldwide.

On Tuesday, concerns about the sustainability of the artificial-intelligence spending boom triggered a sharp selloff across the semiconductor sector.

The Philadelphia Semiconductor Index fell nearly 8%, while major U.S. technology stocks and chipmakers posted significant losses.

The Nasdaq Composite dropped more than 2%, and semiconductor-focused exchange-traded funds suffered some of their largest declines of the year.

Now investors are focused on a single event.

Micron Technology’s earnings report has become one of the most anticipated corporate releases of the quarter because many analysts view the company as a key indicator of demand across the AI supply chain.

Micron manufactures memory chips used in artificial-intelligence systems, data centers, cloud-computing infrastructure, and advanced computing platforms.

Its high-bandwidth memory products have become especially important as AI developers race to build larger and more powerful computing systems.

The company has previously stated that its high-bandwidth memory production for 2026 is effectively sold out and that customer demand continues exceeding available supply.

That strength has helped fuel one of the most powerful rallies in the semiconductor sector.

But it has also raised expectations.

Investors are increasingly asking whether the massive amounts of money being spent on AI infrastructure can continue growing at the current pace.

Those concerns contributed directly to Tuesday’s market decline.

Analysts say Micron’s guidance may provide one of the clearest answers yet regarding whether AI-related demand remains as strong as the market has assumed.

A strong earnings report could reassure investors that spending remains supported by genuine customer orders.

A weaker outlook could reinforce fears that companies are investing ahead of actual demand.

The stakes are particularly high because semiconductor stocks have become a major driver of overall market performance.

A relatively small group of AI-related companies has accounted for a significant portion of stock-market gains over the past two years.

As a result, weakness in chip stocks increasingly affects major indexes, retirement accounts, pension funds, and technology-focused investment portfolios.

Investors are also monitoring broader economic developments.

Markets continue awaiting fresh inflation data, including the Personal Consumption Expenditures (PCE) Index, the Federal Reserve’s preferred inflation gauge.

Recent comments from Fed officials have reinforced expectations that interest rates could remain elevated longer than previously anticipated.

Higher rates tend to pressure high-growth technology stocks because future earnings become less valuable when discounted at higher borrowing costs.

Meanwhile, easing tensions in the Middle East and improving shipping conditions through the Strait of Hormuz have helped reduce oil prices, providing some relief to inflation concerns.

For now, the rebound in Seoul offers investors a temporary pause after a turbulent trading session.

Whether it marks the beginning of a broader recovery or simply a brief respite before further volatility may depend largely on what Micron reports.

In a market increasingly driven by AI expectations, one earnings report has become a critical test of whether the industry’s spending boom still has room to run.
