U.S. Stock Market Recap
On Tuesday, April 28, U.S. stocks closed lower as the AI sector led the decline. Both the S&P 500 and Nasdaq retreated from record closing levels set the prior day, with concerns about slowing artificial intelligence momentum triggering broad-based selloffs in mega-cap tech names. Reuters reported that "new concerns about AI growth weighed on technology stocks as five major tech firms are set to report earnings within days."
Specifically, a bearish report tied to OpenAI shook market confidence in AI momentum, while rising oil prices added to headwinds. The Dow Jones Industrial Average, meanwhile, fell 62.67 points (-0.13%) to 49,168.04 as of April 27. This week is packed with mega-cap earnings releases, key U.S. economic data including GDP and PCE, and major central bank decisions, creating a cautious holding pattern among investors.

-
AMD (Advanced Micro Devices) — +13.91%: Among top S&P 500 gainers as of April 24, buoyed by sustained expectations for AI accelerator demand. However, this week's resurgence of AI concerns may trigger expanded volatility.

Macro & Economic Indicators
-
Oil prices rise — WTI sustains break above $100: Iran's display of Hormuz Strait control and the UAE's OPEC withdrawal announcement have intensified supply anxieties. Crude oil rose further on April 28; Reuters reported that "Iran tensions at an impasse and UAE's OPEC exit news drove oil higher." Rising energy prices lift inflation expectations and dampen Fed rate-cut hopes.
-
Weakening Fed rate-cut expectations: According to Bloomberg, inflation acceleration stemming from Iran tensions has significantly dimmed expectations for Fed rate cuts this year. Treasury yields have risen since the March CPI release, with the 30-year yield climbing nearly 3bp—reflecting pronounced strength in long-duration rates.
-
IMF World Economic Outlook (April 2026): The IMF warned in its April outlook that global growth is decelerating under the shadow of conflict, with inflation pressures rising again. It emphasized the importance of nimble policy responses and managing fiscal conditions amid increased defense spending.
Global Top News (by Market Impact)
UAE Exits OPEC — Turning Point for Oil and Energy Markets
- What happened: The UAE announced it would sever ties with OPEC, sending a shockwave through energy markets. Combined with Iran's control of the Hormuz Strait, global crude supply chain anxiety has hit peak levels. Reuters reported that "oil prices rose amid the UAE's OPEC exit news and Iran tensions at an impasse."
- Market implications: Rising oil prices directly impact aviation, chemicals, and refining sectors. For Korea, higher energy import costs strain the current account. Stocks like SK Innovation and Lotte Chemical may see expanded volatility.
Hormuz Strait Blockade Prolonged — Global Energy Supply Crisis
- What happened: According to Reuters analysis, roughly two months into the Hormuz blockade, global crude inventories have been depleted by 8.2 billion barrels. Asian nations are experiencing actual supply shortages first, with Europe expected to face identical pressures once inventories run dry.
- Market implications: Korea's heavy reliance on Middle Eastern crude oil imports exposes it directly to supply risk. Refiner strength and energy-intensive sector earnings concerns coexist simultaneously.

AI Growth Slowdown Fears — OpenAI Bearish Report Shock
- What happened: A bearish report tied to OpenAI has cast doubt on AI industry momentum broadly. With Microsoft, Meta, Alphabet, Amazon, and Apple set to report earnings this week, investors are closely watching whether AI capex spending continues.
- Market implications: Direct impact on SK Hynix and Samsung Electronics, whose fortunes are tied to semiconductor and AI infrastructure demand. If big tech earnings miss expectations, downward CapEx guidance could follow—particularly for HBM demand.
U.S.-Iran Nuclear Talks at Impasse — Middle East Risks Prolonged
- What happened: The White House announced it is reviewing proposals received from Iran via President Trump, though no tangible breakthrough has emerged. Iran continues to flaunt control over the Hormuz Strait; on April 22, Iran even seized two cargo vessels.
- Market implications: Prolonged geopolitical uncertainty stimulates safe-haven demand, pushing the dollar stronger and Korean won weaker. This creates incentives for foreign investors to sell Korean equities.
Korea Market Checkpoints
With AI concerns resurging and tech stocks falling in overnight U.S. trading, both KOSPI and KOSDAQ are expected to open weaker, led by AI-linked semiconductor names like SK Hynix and Samsung Electronics. If oil prices rise further due to the Hormuz blockade and UAE's OPEC exit, refining and chemical stocks may enjoy short-term tailwinds—but broader economic slowdown fears could dominate. The won-dollar rate faces additional upward pressure amid persistent Middle East risks and dollar strength; big tech earnings this week will be the key variable determining domestic semiconductor sector direction.
Must-Watch Today
- Economic data/events: U.S. Q1 GDP growth release expected (Korean evening). Results versus consensus may trigger a reset in Fed rate policy expectations.
- Earnings reports: Meta (META), Microsoft (MSFT), Alphabet (GOOGL), Amazon (AMZN), and Apple (AAPL) report sequentially this week. AI capital expenditure (CapEx) guidance is the market's top focal point.
- Fed/policy events: FOMC meeting results and Chair Powell remarks. Watch for signals on prolonged rate holds amid resurgent inflation.
- Risk factors: ① Additional Iran provocation at Hormuz could trigger crude spike and broad market crash. ② Disappointing big tech AI CapEx guidance risks cascading selloff in semiconductor and AI sectors.
Investor Action Items
- Monitor semiconductor sector selling pressure at open: With AI concerns resurfacing, check whether SK Hynix and Samsung face foreign selling in the first 30 minutes and decide on position adjustments accordingly.
- Short-term energy/refiner tracking: If oil prices keep rising, S-Oil and SK Innovation may offer brief trading opportunities—but pair this with ongoing checks on global slowdown risk.
- Recommend cutting leverage ahead of big tech earnings: This week brings a triple convergence of mega-cap earnings, GDP data, and FOMC—expect potential volatility spikes. Reducing leverage and raising cash allocation is a prudent tactic for unexpected swings.
