MongoDB exceeded analyst projections with a solid increase in second-quarter sales and an upgraded full-year outlook. Despite these gains, investors reacted sharply to the results, sending shares down 14% to $373.50 in after-hours trading. The disconnect suggests that market expectations may have already priced in the company's growth trajectory.

In contrast, Dell Technologies saw its stock climb 6.4% to $451.99. The hardware manufacturer raised its annual revenue guidance by $25 billion, fueled by a surge in demand for its server products. Meanwhile, Palo Alto Networks reported a fiscal fourth-quarter loss tied to recent acquisition expenses. Though the firm anticipates double-digit growth driven by consistent cybersecurity demand, its shares slipped 2.2% to $354.11.
