Key Takeaways
- SK Hynix (000660) reported a record quarterly operating profit of 60.54 trillion won ($43.7 billion), a 557% year-over-year surge, yet shares fell as results narrowly missed the most aggressive analyst estimates for the AI sector.
- The Federal Aviation Administration (FAA) issued a nationwide ground stop for American Airlines (AAL) on Tuesday evening following a "systemwide IT outage," halting departures for over an hour.
- Iran's military officially denied any involvement in projectiles launched toward Saudi Arabia, distancing itself from recent regional escalations involving Iran-backed militias in Iraq and Yemen.
- SK Hynix confirmed it has finalized long-term agreements with approximately 10 key customers for its next-generation HBM4 chips, securing its lead in the Nvidia (NVDA) supply chain.
Tech Giants and Infrastructure Under Pressure
Global markets and infrastructure faced a turbulent Tuesday as a major semiconductor earnings report coincided with a significant aviation disruption in the United States. SK Hynix (000660), a critical supplier of high-bandwidth memory (HBM) for Nvidia (NVDA), posted its most profitable quarter in company history. Despite a 557% jump in operating profit, the company’s stock faced pressure in after-hours trading as investors weighed whether the "AI supercycle" can maintain its current trajectory.
The company reported 79.32 trillion won in revenue, marking the first time its half-year revenue has surpassed the 100 trillion won milestone. Market sentiment remained cautious, however, as the operating margin of 76%—while industry-leading—fell just short of the "lofty expectations" set by some institutional investors. SK Hynix remains optimistic, noting that its HBM4 development is meeting customer requirements for power efficiency and cost-competitiveness.
Aviation Ground Stop Hits American Airlines
Domestic travel in the U.S. was thrown into chaos Tuesday evening when the Federal Aviation Administration (FAA) grounded all American Airlines (AAL) flights. The agency cited a "technical issue" that the airline later clarified as a systemwide IT outage. The ground stop, which began around 6:30 p.m. ET, prevented aircraft from departing at all American facilities and regional carrier hubs.
By 7:21 p.m. ET, American Airlines announced that its systems were coming back online and flights were resuming. The carrier apologized for the inconvenience, though the outage resulted in over 130 fewer flights being airborne compared to the same period last week. The disruption comes at a sensitive time for the industry, as East Coast airports were already struggling with significant delays due to summer thunderstorms.
Geopolitical Tensions and Denials in the Middle East
On the geopolitical front, Iran moved to de-escalate tensions with Saudi Arabia following reports of projectiles targeting the Kingdom. An Iranian military official, speaking via state television, stated that Tehran has "no connection" to any projectiles launched from third-party countries. The statement follows allegations from the Saudi Defense Ministry that air defenses had intercepted drones launched from Iraqi territory by "Iran-affiliated terrorist militias."
The denial is seen as an attempt to prevent a direct confrontation between the regional powers, even as U.S. Central Command reported thwarting separate Iranian ballistic missile attacks on American forces in the region earlier that day. Analysts suggest that while Iran is distancing itself from specific strikes, the activity of its regional proxies continues to keep volatility elevated in international oil prices and risk-asset sentiment.
