Korean stocks face downward pressure on May 8 as the KOSPI seeks direction amid dual headwinds: US semiconductor stock weakness and escalating Middle East geopolitical risks. The KOSPI fell 4.91% to 7656.31 on May 7, triggering both a sidecar halt in morning trading and a circuit breaker in the afternoon. The sharp decline followed Samsung Electronics' better-than-expected earnings release, which failed to prevent profit-taking and foreign selling pressure. Analysts attribute the sell-off to mounting concerns over AI investment expansion and Middle East tensions, particularly after three oil tankers were attacked near the Strait of Hormuz within 24 hours, prompting US airstrikes against Iran. Despite the volatility, market strategists note the KOSPI's 12-month forward price-to-earnings ratio remains below 8x, suggesting valuation appeal persists even as options expiration on May 9 may amplify intraday swings.
US Semiconductor Stocks Record Sharp Declines on May 7
US semiconductor stocks weighed on market sentiment as the Philadelphia Semiconductor Index fell 4.65% on May 7. Intel dropped 9.66%, AMD declined 6.51%, Micron fell 4.71%, KLA retreated 7.22%, and Marvell Technology slid 7.45%. Concerns emerged over AI investment expansion after Samsung Electronics' earnings report, with recent aggressive investment announcements from Korean companies and Micron's Japan factory construction interpreted as potential long-term oversupply issues. The Nasdaq Composite closed down 1.16% at 25,818.69, while the S&P 500 fell 0.45% to 7,503.85. However, semiconductor sector losses moderated intraday after SK Hynix's ADR offering confirmed significant demand from global institutional investors. Among major tech stocks, Meta rose 2.55%, Microsoft gained 0.54%, and Amazon advanced 0.75%, while Alphabet dipped 0.35% and Apple fell 0.64%. Penguin Solutions, an AI infrastructure solutions provider, surged approximately 9% in after-hours trading following better-than-expected earnings results.
Three Oil Tankers Attacked Near Strait of Hormuz
Middle East geopolitical risks intensified investor caution after three oil tankers were attacked near the Strait of Hormuz within the past 24 hours, according to the UK Maritime Trade Operations (UKMTO). The US stated that "the aggressive actions shown by Iran are unjustifiable, dangerous, and a clear violation of the ceasefire" and announced it had launched airstrikes against Iran to hold the country accountable for the attacks. Brent crude for September delivery closed 3% higher at $74.16 per barrel, while West Texas Intermediate (WTI) for August delivery rose 2.8% to $70.44 per barrel, with further gains in after-hours trading.
KOSPI Falls 4.91% Triggering Trading Halts on May 7
The KOSPI closed at 7,656.31 on May 7, down 395.02 points or 4.91%, despite Samsung Electronics' earnings surprise. The market experienced extreme volatility, with a program sell order temporary suspension (sidecar) activated in the morning and a circuit breaker triggered in the afternoon. Profit-taking and concentrated foreign selling pressure drove the decline. Overnight, the MSCI Korea ETF fell 4.51% and KOSPI 200 night futures dropped 2.61%. Options expiration scheduled for May 9 is expected to amplify intraday volatility.
Analysts Cite Valuation Appeal Despite Volatility
Seo Sang-young, researcher at Mirae Asset Securities, stated that "while Samsung Electronics announced better-than-expected results the previous day, profit-taking emerged, and geopolitical risks surrounding the Strait of Hormuz and Taiwan Strait intensified during trading, expanding the decline." He explained that "the market's topic was Samsung Electronics, but what actually expanded the index decline was geopolitical risk related to the Middle East and Taiwan, as evidenced by the widening losses after related news emerged." Seo projected a lower opening is inevitable given semiconductor companies' weakness in US markets and persistent geopolitical uncertainty, but noted "rebound buying following the previous day's sharp decline is highly likely to flow in." He added that concerns surrounding semiconductors have been raised continuously since late last year and represent "a process of partially adjusting heightened expectations rather than new negative factors, and will not cause sustained anxiety." Seo emphasized that "the KOSPI's 12-month forward earnings per share (EPS) exceeds 1,000 points, while the current index remains below an 8x 12-month forward price-to-earnings ratio (PER), so valuation appeal remains valid." He also noted that Penguin Solutions' better-than-expected results and solid forward outlook announced after US market close "are factors that partially alleviate concerns over data center construction delays, and investor sentiment is likely to stabilize," though "volatility during trading is likely to expand ahead of options expiration on May 9."
