While the retail giant beat earnings expectations and raised its full-year guidance, the market focused on a sharp drop in transaction growth, which halved from <strong>3.0%<\/strong> in Q1 to <strong>1.5%<\/strong> in Q2. CEO John Furner noted that while inflation remains &quot;pretty low&quot; throughout the year, price-sensitive consumers are increasingly prioritizing essentials over discretionary spending.<\/p>\n<p>In the biotech sector, <strong>Moderna (<a href=\"\/stock\/MRNA\">MRNA<\/a>)<\/strong> experienced a volatile retracement, dropping <strong>19%<\/strong> following Wednesday\u2019s historic surge. The previous day&#39;s rally, which added nearly <strong>$44 billion<\/strong> to the company&#39;s market cap, was sparked by successful Phase 3 results for its personalized mRNA cancer vaccine developed with Merck (<a href=\"\/stock\/MRK\">MRK<\/a>). Analysts attributed Thursday&#39;s decline to profit-taking and technical &quot;overbought&quot; conditions, as the stock&#39;s Relative Strength Index (RSI) hit an all-time high of <strong>92.2<\/strong>.<\/p>\n<h2>Economic Indicators and Federal Reserve Outlook<\/h2>\n<p>The Conference Board reported that the <strong>U.S. Leading Economic Index (LEI)<\/strong> increased by <strong>0.2%<\/strong> in July to <strong>99.5<\/strong>, beating expectations of <strong>0.1%<\/strong>. This uptick marks a critical turning point, as the index&#39;s six-month growth rate turned positive for the first time since 2022. The Conference Board now forecasts real GDP growth of <strong>1.9%<\/strong> for both 2026 and 2027, driven largely by business investments in <strong>Artificial Intelligence<\/strong>.<\/p>\n<p>San Francisco Fed President <strong>Mary Daly<\/strong> reinforced a data-dependent stance in recent comments, stating she sees &quot;no signs the labor market is faltering.&quot; Daly emphasized that the Federal Reserve is in a &quot;good place&quot; to monitor incoming data before making further policy shifts. She downplayed the recent rise in long-term Treasury yields as a global phenomenon rather than a signal for immediate domestic rate hikes.<\/p>\n<h2>Corporate Developments and Geopolitical Tensions<\/h2>\n<p><strong>Super Micro Computer (<a href=\"\/stock\/SMCI\">SMCI<\/a>)<\/strong> announced the completion of an independent investigation into alleged export-control violations. The probe found no evidence that current senior management was aware of a scheme to divert restricted products to banned parties. Following the report, the board approved new measures to enhance its export compliance program, and the company terminated several employees for failing to follow internal rules.<\/p>\n<p>On the geopolitical front, <strong>Yemen&#39;s Houthis<\/strong> claimed to have attacked &quot;sensitive&quot; targets at Saudi Arabia&#39;s <strong>Najran Airport<\/strong> and an <strong>Aramco<\/strong> facility. While there has been no immediate confirmation from Saudi authorities, the claim follows a series of escalated strikes in the region. Meanwhile, White House officials indicated that President Trump is currently focused on &quot;strangling Iran economically&quot; through Treasury-led sanctions rather than immediate military escalation, placing Treasury Secretary <strong>Scott Bessent<\/strong> at the forefront of the administration&#39;s &quot;maximum pressure&quot; campaign.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways Walmart (WMT) shares plummeted 8.7%, marking its sharpest one-day decline since July 2022, after reporting a significant deceleration [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":50383,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"rank_math_schema_Article":[],"rank_math_focus_keyword":[],"rank_math_description":[],"financial_data_references":[],"stock_symbols_mentioned":[],"footnotes":""},"categories":[5012],"tags":[277,595,1524,3709,4223,4824,10660,12098,21817],"class_list":["post-66801","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-breaking-news","tag-wmt","tag-smci","tag-mrna","tag-fed","tag-inflation","tag-geopolitics","tag-rsi","tag-lei","tag-virt"],"_links":{"self":[{"href":"https:\/\/www2.stockmarketwatch.com\/stock-market-news\/wp-json\/wp\/v2\/posts\/66801","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www2.stockmarketwatch.com\/stock-market-news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www2.stockmarketwatch.com\/stock-market-news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www2.stockmarketwatch.com\/stock-market-news\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www2.stockmarketwatch.com\/stock-market-news\/wp-json\/wp\/v2\/comments?post=66801"}],"version-history":[{"count":0,"href":"https:\/\/www2.stockmarketwatch.com\/stock-market-news\/wp-json\/wp\/v2\/posts\/66801\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www2.stockmarketwatch.com\/stock-market-news\/wp-json\/wp\/v2\/media\/50383"}],"wp:attachment":[{"href":"https:\/\/www2.stockmarketwatch.com\/stock-market-news\/wp-json\/wp\/v2\/media?parent=66801"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www2.stockmarketwatch.com\/stock-market-news\/wp-json\/wp\/v2\/categories?post=66801"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www2.stockmarketwatch.com\/stock-market-news\/wp-json\/wp\/v2\/tags?post=66801"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
