The exchange operator confirmed that all systems are now operating normally after an alert was originally issued at <strong>11:27 a.m. ET<\/strong> regarding issues at its <strong>Carteret data center<\/strong>.<\/p>\n<p>The outage was widespread, affecting several multicast groups and impacting both the primary and secondary data feeds for the <strong>Nasdaq<\/strong>, <strong>Nasdaq Texas<\/strong>, and <strong>Nasdaq PSX<\/strong> exchanges. During the disruption, Nasdaq instructed clients experiencing data gaps to submit recovery requests for missing information and encouraged a transition to unaffected backup feeds located in <strong>Chicago<\/strong>.<\/p>\n<h2>Market Context and Volatility<\/h2>\n<p>The technical glitch coincided with significant volatility in the technology sector. The <strong>Nasdaq Composite<\/strong> (<a href=\"\/stock\/COMP\">COMP<\/a>) dropped approximately <strong>1.88%<\/strong> in the previous session and continued its decline on Thursday, falling another <strong>1.4%<\/strong> at the opening bell.<\/p>\n<p>Investor sentiment has been pressured by a hotter-than-expected <strong>Consumer Price Index (CPI)<\/strong> report, which showed inflation rising to <strong>3.7%<\/strong> in September. This has fueled fears of further interest rate hikes by the <strong>Federal Reserve<\/strong>, increasing the cost of capital for high-growth companies like <a href=\"https:\/\/stockmarketwatch.com\/stock\/NVDA\" data-internallinksmanager029f6b8e52c=\"15\" title=\"stock: NVDA\">Nvidia<\/a> (<a href=\"\/stock\/NVDA\">NVDA<\/a>), which saw its shares slip nearly <strong>2%<\/strong> in tandem with the broader market rout.<\/p>\n<h2>Impact on AI and Semiconductor Stocks<\/h2>\n<p>The disruption added to a nervous atmosphere for artificial intelligence and semiconductor firms. CoreWeave (<a href=\"\/stock\/CRWV\">CRWV<\/a>), a major AI infrastructure provider, saw its stock tumble over <strong>15%<\/strong> on Wednesday and continued to slide on Thursday as investors questioned the sustainability of high capital expenditures in a rising rate environment.<\/p>\n<p>Other major tech players, including Advanced Micro Devices (<a href=\"\/stock\/AMD\">AMD<\/a>) and <a href=\"https:\/\/stockmarketwatch.com\/stock\/MU\" data-internallinksmanager029f6b8e52c=\"20\" title=\"Stock: MU\">Micron<\/a> (<a href=\"\/stock\/MU\">MU<\/a>), also faced downward pressure, falling roughly <strong>3.5%<\/strong> and <strong>4.5%<\/strong> respectively in <a href=\"https:\/\/stockmarketwatch.com\/movers\/premarket\" data-internallinksmanager029f6b8e52c=\"7\" title=\"Premarket Movers\">premarket<\/a> trading. While Nasdaq (<a href=\"\/stock\/NDAQ\">NDAQ<\/a>) has resolved the technical &quot;gapping&quot; issues, the exchange continues to monitor its systems to ensure stability as trading volumes remain high during this period of market repricing.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways Nasdaq (NDAQ) has fully restored all systems following a network disruption at its
