On Tuesday, the U.S. stock market witnessed a broad decline, with major indexes faltering. This downturn was largely attributable to an unexpected contraction within the nation's services sector during July, coupled with the continued focus on evolving trade policies. The S&P 500, Dow, and Nasdaq Composite each registered losses, reflecting a day of varied fortunes across different industries. While some companies faced significant setbacks due to disappointing earnings and shifts in strategic focus, others celebrated substantial gains driven by robust demand for innovative technologies, particularly in artificial intelligence.
Gartner, a prominent technology research and advisory firm, experienced a steep decline of nearly 28% in its share price, marking the poorest performance within the S&P 500. This sharp drop occurred despite second-quarter revenues and adjusted earnings per share surpassing analyst expectations. The primary cause for concern was Gartner's revised full-year sales guidance, which fell short of market predictions. The company attributed this lowered outlook to a softening demand within its core insights segment, a critical revenue driver, as businesses globally began to curb expenditures in response to an unpredictable economic landscape.
Similarly, Vertex Pharmaceuticals saw its shares fall by 21%. Despite reporting strong second-quarter results that exceeded both revenue and profit forecasts, largely propelled by increased sales of its cystic fibrosis treatment, the biopharmaceutical company made a significant announcement. It disclosed the cessation of development for an investigational next-generation pain management drug, following its failure to achieve the primary objective in a recent Phase 2 clinical trial. This decision highlights the inherent risks and challenges associated with pharmaceutical research and development, where even promising candidates can encounter unexpected hurdles.
In contrast, several companies defied the market's downward trend, demonstrating resilience and growth. Axon Enterprise, known for its Taser devices and other law enforcement equipment, saw its shares surge by over 16%, making it the top performer in the S&P 500. The company not only surpassed its second-quarter sales and profit estimates but also raised its full-year guidance, buoyed by the increasing momentum of its software business and robust demand for its generative artificial intelligence solutions, including AI-powered tools designed to streamline police report generation from camera footage.
Palantir Technologies, a leader in AI software, also posted impressive results, with its stock rising by 7.8%. The company updated its 2025 outlook after exceeding sales and profit expectations for the second quarter, primarily crediting the strong uptake of its Artificial Intelligence Platform for contributing to a record-breaking quarterly revenue of $1 billion. Following these stellar results, leading financial institutions like Bank of America, Morgan Stanley, and Deutsche Bank all revised their price targets for Palantir upwards, signaling heightened confidence in its future prospects.
Meanwhile, Leidos Holdings, an aerospace and defense contractor, experienced a 7.5% increase in its shares after its quarterly earnings release. The company reported adjusted earnings per share significantly above forecasts, with revenues slightly exceeding expectations. Leidos cited an increase in demand across its various customer segments, particularly highlighting the strength in its defense systems unit, which benefited from elevated geopolitical tensions. Advancements in artificial intelligence and maritime autonomy also played a crucial role in underpinning the company's strong performance, showcasing the diverse applications and growing importance of cutting-edge technologies.
Overall, the market's performance on Tuesday underscored the complex interplay of economic indicators, corporate earnings, and global trade dynamics. While broader market indexes reflected a cautious sentiment, individual company performances revealed distinct trends, with AI and defense-related sectors showing notable strength amidst an otherwise challenging trading environment.
