Earnings

Several companies reported their earnings today, with notable performances from Envista, Dave, and CoreWeave. Envista (NVST) reported a strong Q2 2026, with margins expanding by 230 basis points as core growth accelerated. Dave (DAVE) also had a robust quarter, with revenue surging 30% due to increased member acquisition and significant growth in average revenue per user (ARPU). Meanwhile, CoreWeave saw its stock jump 19% after reporting that its second-quarter revenue doubled, driven by surging demand for AI services from hyperscalers.

However, not all earnings reports were positive. Cisco's stock dropped despite beating earnings and revenue estimates, as the results did not meet Wall Street's expectations. Additionally, Cerebras Systems experienced a significant decline, with its stock plunging 14% after its second earnings report following its IPO, despite reporting better-than-expected revenue and raising its full-year guidance.

Macroeconomics

The market reacted positively to a mild consumer inflation report for July, which indicated that inflation pressures may be easing. This has led to speculation about the Federal Reserve's next moves regarding interest rates. Investors are closely monitoring these developments, as the inflation data could significantly influence monetary policy in the near term.

Corporate News

In corporate news, Black Hills (BKH) discussed its data center expansion and merger progress during its earnings call, highlighting a strong recovery in rates. The overall sentiment in the tech sector remains optimistic, particularly following the positive results from CoreWeave, which have fueled enthusiasm around AI infrastructure.

Outlook

Looking ahead, the market's direction will likely hinge on upcoming economic data, particularly regarding inflation and consumer spending. With the Federal Reserve's stance on interest rates in focus, investors will be keen to see how these factors play out in the coming weeks. The tech sector's performance will also be critical, especially as companies continue to report earnings and provide guidance amid a rapidly changing economic landscape.
