The Dow Jones Industrial Average (DJIA) concluded the day down 73.61 points (-0.17%) at 44,100.03.

Rivian's Q2 Performance Falls Short on Deliveries and Production
Electric vehicle manufacturer Rivian (RIVN) reported its second-quarter earnings, revealing a mixed financial picture. The company posted revenue of $1.30 billion, slightly surpassing the estimated $1.28 billion. However, Rivian's adjusted loss per share came in at $0.80, wider than the estimated loss of $0.63. Production figures also disappointed, with 5,979 vehicles produced against an estimated 7,411. Vehicle deliveries totaled 10,661, falling short of the 10,829 expected. The company's cash and cash equivalents also saw a decline, ending the quarter at $4.81 billion compared to an estimated $5.29 billion. Despite these misses, Rivian maintained its full-year vehicle outlook. Analysts had been cautious ahead of the report, citing weak deliveries and broader macro pressures impacting the EV market.
Amgen Exceeds Expectations and Raises Full-Year Outlook
In contrast, biotechnology giant Amgen (AMGN) delivered a robust second-quarter earnings report, outperforming analyst expectations across key metrics. The company reported revenue of $9.18 billion, exceeding the estimated $8.91 billion. Adjusted earnings per share (EPS) reached $6.02, significantly higher than the $5.26 estimated by analysts. Adjusted operating income also surpassed forecasts, coming in at $4.29 billion against an estimated $3.95 billion. Following the strong performance, Amgen raised its full-year revenue guidance to a range of $35 billion to $36 billion, up from the prior $34.3 billion to $35.7 billion. The company also increased its full-year adjusted EPS guidance to $20.20 to $21.30, from the previous $20.00 to $21.20. This positive outlook is partly attributed to strategic acquisitions that have bolstered Amgen's rare disease pipeline.
Amazon Expands AI Offerings with OpenAI Integration
Amazon (AMZN) made a significant announcement in the artificial intelligence space, revealing that it will now offer OpenAI's open-weight models on its Amazon Bedrock and SageMaker platforms for the first time. This move ends Microsoft's (MSFT) exclusive cloud resale of these models and aims to boost Amazon Web Services (AWS) AI tool choice amidst growing rivalry in the sector. AWS reported a 17% increase in revenue for Q2, reaching $30.9 billion. The integration includes OpenAI's new gpt-oss-120b and gpt-oss-20b foundation models, which support advanced reasoning and generative AI applications.
Tesla's German Sales Plummet Amidst Broader EV Growth
Tesla's (TSLA) performance in the German market saw a sharp decline in July. The company's car sales in Germany more than halved, dropping by 55.1% year-over-year. This significant reduction comes despite the overall German electric vehicle market experiencing a robust 58% increase in new battery electric vehicle registrations in July. For the January-July period, Tesla's sales in Germany fell 57.8% to 10,000 units compared to the same period in 2024. This stark contrast highlights increasing competition and potential shifts in consumer preference within Europe's largest auto market, with Chinese automaker BYD seeing a nearly fivefold surge in sales in Germany during the same month.
