The benchmark <strong>KOSPI index tumbled 8%<\/strong>, forcing the Korea Exchange to activate a circuit breaker and halt trading for 20 minutes. The sell-off was led by a collapse in the semiconductor sector; Samsung Electronics (<a href=\"\/stock\/005930\">005930<\/a>) fell <strong>9.75%<\/strong>, while SK Hynix (<a href=\"\/stock\/000660\">000660<\/a>) plummeted over <strong>10%<\/strong>.<\/p>\n<p>This rout has been particularly devastating for retail investors who heavily utilized <strong>single-stock leveraged ETFs<\/strong>. Since their launch on May 27, approximately <strong>$9.45 billion<\/strong> has flowed into these products. Regulators are now weighing strict limits on retail exposure as volatility in the underlying stocks has amplified losses, with some 2x leveraged funds losing nearly half their value in just weeks.<\/p>\n<h2>Big Tech\u2019s AI Debt Binge<\/h2>\n<p>In the United States, a fundamental shift is occurring in how the market prices the debt of &quot;hyperscalers.&quot; Long-dated bonds issued by major tech firms are now trading with credit spreads approaching those of <strong>BB-rated (junk) bonds<\/strong>, despite the companies maintaining high investment-grade ratings.<\/p>\n<p>Investors are increasingly wary of the scale and duration of <strong>AI-related capital spending<\/strong>. With capital expenditures across the sector projected to reach <strong>$785 billion in 2026<\/strong>, the bond market is signaling that the &quot;asset-light&quot; era of Big Tech is over, replaced by a capital-intensive model that requires massive physical infrastructure.<\/p>\n<h2>China\u2019s Semiconductor Milestone<\/h2>\n<p>While broader Chinese markets opened weak\u2014with the <strong>Star 50 Index<\/strong> heading for a <strong>3% decline<\/strong>\u2014the listing of <strong>CXMT<\/strong> provided a stark contrast. The memory chipmaker\u2019s shares surged <strong>466%<\/strong> upon their Shanghai debut, reaching a valuation of approximately <strong>3.7 trillion yuan ($547 billion)<\/strong>.<\/p>\n<p>This IPO, the second-largest in China\u2019s history, reflects the strategic importance of domestic DRAM production. However, the sheer size of the listing has raised concerns about <strong>liquidity drainage<\/strong> from other sectors of the Chinese market, contributing to the slide in the Star 50 and other tech-heavy indices.<\/p>\n<h2>Macroeconomic Headwinds<\/h2>\n<p>Global sentiment remains fragile as the <strong>Federal Reserve&#39;s July rate decision<\/strong> looms. Bitcoin (<a href=\"\/stock\/BTC\">BTC<\/a>) weakened in Asia trading, dropping toward the <strong>$64,000<\/strong> level, while Ethereum (<a href=\"\/stock\/ETH\">ETH<\/a>) fell over <strong>4%<\/strong>. Markets are currently pricing in a high probability that the Fed will maintain the federal funds rate at <strong>3.50%\u20133.75%<\/strong>, but investors are laser-focused on Chair Kevin Warsh&#39;s press conference for signals regarding a potential September hike.<\/p>\n<p>In geopolitical developments, South Korea is moving forward with a <strong>special bill on nuclear-powered submarines<\/strong>. The legislation will specifically include a commitment not to develop nuclear weapons, an effort to secure U.S. technological cooperation while dispelling international concerns over Seoul&#39;s nuclear ambitions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways South Korea\u2019s KOSPI index plunged 8%, triggering a 20-minute circuit breaker halt as a massive sell-off in
