South Korean Stocks Recover War Losses as Chipmakers Gain on AI Resurgence

KOSPI Erases Geopolitical Dip as AI Fuels Tech Rebound

The Korea Composite Stock Price Index ($KOSPI) has fully erased the losses incurred during the mid-April escalation of Iran-Israel tensions, closing at 2,750.21 on May 7. This significant rebound marks a 7.85% recovery from its April 19 low of 2,549.95, driven predominantly by a robust rally in the nation's semiconductor sector. The benchmark index, which experienced a sharp decline of 4.3% in the week following the initial conflict reports, has demonstrated resilience, with foreign investors leading the charge back into the market.

Investor sentiment has rapidly shifted from risk aversion to a renewed focus on growth opportunities, particularly within the technology sector. Trading volumes on the KOSPI surged on Tuesday, reaching 1.2 billion shares, well above the 30-day average of 950 million, indicating strong buying interest. This swift reversal underscores the market's capacity to compartmentalize geopolitical risks when faced with compelling fundamental tailwinds.

Market Impact

The KOSPI's ascent to 2,750.21 on Tuesday represents its highest close since April 10, prior to the initial geopolitical shock. The recovery has been broad-based but heavily concentrated in large-cap technology stocks. Samsung Electronics $005930, the nation's largest company by market capitalization, has climbed 5.1% over the past two weeks, reaching 77,200 Korean Won ($KRW) per share. SK Hynix $000660, a key player in high-bandwidth memory (HBM) chips, outperformed with an 8.3% gain to close at $KRW178,500, pushing its market capitalization to over $KRW130 trillion.

This strong performance contrasts sharply with the index's decline to its lowest point in over three months on April 19. The current rally marks the fastest recovery from a geopolitical-induced downturn of this magnitude since the 2017 North Korean missile crisis, which saw the index regain losses within two weeks. Foreign investors have been significant drivers of this upward momentum, recording net buying of $1.2 billion in South Korean equities since April 22, according to Korea Exchange data.

The strengthening equity market has also had a spillover effect on the currency, with the Korean Won ($KRW) firming against the U.S. Dollar. The $USD/KRW exchange rate has retreated from its recent high of 1,388 to trade around 1,365, reflecting increased capital inflows and improved investor confidence in the South Korean economy. While global tensions remain a backdrop, the market's immediate focus has clearly pivoted to the burgeoning demand for AI-related hardware.

What Analysts Are Saying

Analysts are largely optimistic about the continued trajectory of South Korean chipmakers, citing robust demand for high-bandwidth memory (HBM) chips essential for AI applications. "The structural growth in AI demand is a powerful long-term driver for Korean semiconductor companies, overshadowing short-term geopolitical noise," stated Kim Young-gun, an analyst at Mirae Asset Securities. "We project a 15-20% earnings upside for SK Hynix in 2024, primarily driven by HBM3e shipments."

However, some caution remains regarding the sustainability of the rally amidst broader global uncertainties. "While the immediate recovery is impressive, investors should not dismiss the persistent risks from US-Iran tensions and potential shifts in global monetary policy," noted David Lee, Head of Korea Equities Research at JPMorgan. "The KOSPI's rapid ascent could trigger some profit-taking in the near term, especially if the macroeconomic data from China or the US disappoints."

Goldman Sachs analysts, in a recent note, highlighted the increasing pricing power of memory chip manufacturers. "The supply-demand dynamics for DRAM and NAND are tightening, with HBM leading the charge," the report stated. "This allows companies like Samsung $005930 and SK Hynix $000660 to command higher prices, directly translating into improved margins and stronger earnings outlooks for the remainder of 2024."

What to Watch

Investors will closely monitor upcoming earnings reports from key chipmakers for further confirmation of the AI-driven growth narrative. Samsung Electronics $005930 is expected to release its detailed second-quarter earnings results in late July, following its preliminary strong guidance. SK Hynix $000660's performance will also be critical, particularly its commentary on HBM production capacity and pricing.

Beyond earnings, the trajectory of global AI development, including major announcements from bellwether companies like Nvidia $NVDA, will serve as a significant catalyst. Any new breakthroughs or increased capital expenditure plans in the AI sector could further fuel demand for South Korean components. Geopolitical developments, particularly regarding US-Iran relations and the ongoing conflict in Ukraine, remain a key risk factor that could quickly reverse market sentiment.

Technically, the KOSPI faces its next significant resistance level around 2,800 points, a level it last consistently held in early 2022. A sustained break above this could signal a more prolonged bullish trend. Conversely, the 2,700 level now acts as immediate support, with a breach potentially indicating a pause or correction in the current rally. The Bank of Korea's monetary policy decisions, with inflation still a concern, could also impact market liquidity and investor appetite.
