 Korean Stocks Drop for Third Day as Traders Digest New Curbs

**South Korea's KOSPI has fallen roughly 15% over the last week, and the newly announced restrictions on short selling are adding to the uncertainty. Here's what the selloff means for global investors.**

---

## Introduction: A Week of Turmoil

The world has become a volatile place for semiconductor investors, particularly those with exposure to South Korean stocks. The KOSPI index fell another 2.24% on Thursday, closing at roughly 6,030 points—a 15% decline over the past week and a roughly 30% drop from its recent peak.

The latest selling pressure comes as the South Korean government announces new restrictions on short selling, a move that has added to the uncertainty swirling around the country's dominant semiconductor sector. After the market closed on Thursday, Korea's financial regulator announced the extension of its short-selling ban, which will now remain in place until **December 2026**.

The regulator also unveiled a new system to detect and penalize illegal short-selling activity, responding to concerns that had been fueling a politically charged debate. In a high-profile case, former prosecutor and current Korea Exchange chairman Jung-Eun-bo was indicted for alleged illegal short-selling in 2024.

## The Numbers: An IPO Discount and a Liquidity Squeeze

The situation has been aggravated by the rapid expansion of the semiconductor sector. SK Hynix, the world's second-largest memory chip maker and a key supplier to Nvidia, has seen its stock more than double this year.

With its U.S. listing at $158.14 per ADR, the stock's price-to-book ratio is roughly **1.6 times**, a discount to both its U.S. peers and the broader market, signaling that the market is pricing in a significant risk premium. However, the sheer number of ADRs listed—nearly 178 million—could add to the selling pressure.

"You can view the current weakness in the semiconductor sector as one where the 'valuation reset is a prelude to a broader rotation rather than the collapse of the AI trade,'" said Chun Kyong-hoon, analyst at Hana Securities.

## The Global Context: AI Trade, China, and the "Casino of Emotions"

The selloff in Korean stocks is not isolated. It is part of a broader global retreat from AI-related assets, as investors question the sustainability of the massive spending on artificial intelligence.

The U.S. semiconductor sector has also been hit hard, with the Philadelphia Semiconductor Index down roughly 25% from its peak. The trigger for the latest slide was SK Hynix's bumper quarterly results, which failed to meet sky-high expectations.

## What to Watch

For investors looking to navigate the uncertainty, the key is to differentiate between short-term volatility and long-term trends. "There are a lot of people under the impression over the last couple of months that these stocks only go up. And if they borrowed money to buy the positions, then they (could be) getting called out of them," said Walter Todd, chief investment officer at Greenwood Capital.
