Despite a <strong>557% jump in operating profit<\/strong>, the company\u2019s stock faced pressure in after-hours trading as investors weighed whether the &quot;AI supercycle&quot; can maintain its current trajectory.<\/p>\n<p>The company reported <strong>79.32 trillion won in revenue<\/strong>, marking the first time its half-year revenue has surpassed the <strong>100 trillion won<\/strong> milestone. <em>Market sentiment remained cautious<\/em>, however, as the operating margin of <strong>76%<\/strong>\u2014while industry-leading\u2014fell just short of the &quot;lofty expectations&quot; set by some institutional investors. SK Hynix remains optimistic, noting that its <strong>HBM4<\/strong> development is meeting customer requirements for power efficiency and cost-competitiveness.<\/p>\n<h2>Aviation Ground Stop Hits American Airlines<\/h2>\n<p>Domestic travel in the U.S. was thrown into chaos Tuesday evening when the <strong>Federal Aviation Administration (FAA)<\/strong> grounded all <strong>American Airlines (<a href=\"\/stock\/AAL\">AAL<\/a>)<\/strong> flights. The agency cited a &quot;technical issue&quot; that the airline later clarified as a <strong>systemwide IT outage<\/strong>. The ground stop, which began around <strong>6:30 p.m. ET<\/strong>, prevented aircraft from departing at all American facilities and regional carrier hubs.<\/p>\n<p>By <strong>7:21 p.m. ET<\/strong>, 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 <strong>130 fewer flights<\/strong> being airborne compared to the same period last week. <em>The disruption comes at a sensitive time for the industry<\/em>, as East Coast airports were already struggling with significant delays due to summer thunderstorms.<\/p>\n<h2>Geopolitical Tensions and Denials in the Middle East<\/h2>\n<p>On the geopolitical front, <strong>Iran<\/strong> moved to de-escalate tensions with <strong>Saudi Arabia<\/strong> following reports of projectiles targeting the Kingdom. An Iranian military official, speaking via state television, stated that Tehran has <strong>&quot;no connection&quot;<\/strong> 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 &quot;Iran-affiliated terrorist militias.&quot;<\/p>\n<p>The denial is seen as an attempt to prevent a direct confrontation between the regional powers, even as <strong>U.S. Central Command<\/strong> reported thwarting separate Iranian ballistic missile attacks on American forces in the region earlier that day. <em>Analysts suggest that while Iran is distancing itself from specific strikes<\/em>, the activity of its regional proxies continues to keep
