The company is also buying back its own shares to support the stock price. While recent daily trading has been uneven, the stock has gained over 41% in the last 90 days. Investors believe WEX is undervalued at its current price of $191.52 compared to a fair value estimate of $187.30. However, some analysts think the stock is priced too high based on future cash flow calculations.

Arista Networks Prepares for AI Infrastructure Summit

Arista Networks is attending the AI Infra & Network Summit in Tokyo to show off its new networking gear designed for AI systems. The company has seen strong growth over the last five years with a total shareholder return of about eight times the original investment. Investors see the stock as undervalued with a fair price of $241.82, though the current price is $199.59. Arista benefits from high demand for faster network switches as data centers upgrade their systems. However, the stock has a high price-to-earnings ratio of 62.2x, which means investors expect very strong future growth.

Viavi Solutions Shows New AI and Optical Test Products

Viavi Solutions recently displayed its new high-speed Ethernet and optical test products at the ECOC 2026 conference in Malaga. The company has seen a massive one-year return of 222.11% as demand for data center upgrades grows. Customers are updating their optical connectivity to faster speeds like 400G, 800G, and 1.6T. Analysts believe the stock is undervalued with a fair price of $61.43, but a cash flow model suggests a lower value of $28.04. The stock faces risks if demand for wireless testing stays weak or if competition in the AI sector increases.

Senate negotiators debate new AI safety laws

U.S. Senate negotiators are discussing a new law that would require tech companies to make their artificial intelligence products safe. This proposal creates a duty of care for developers, meaning they must prevent catastrophic risks like the creation of nuclear or biological weapons. The government would have the power to block unsafe AI models, but companies could challenge this decision in federal court. The bill focuses on the most advanced AI models from companies like Alphabet's Google, Anthropic, and OpenAI. Key lawmakers involved include Senate Majority Leader John Thune, Senator Ted Cruz, and Senator Amy Klobuchar. However, passing this law before the November 3 midterm elections may be difficult due to the short time the House of Representatives will be in session.

AI agents take over nine sales tasks in 2026

A new report from Salesforce shows that AI agents are taking over many tedious sales tasks in 2026. Sellers expect a 34% reduction in time spent on prospect research and a 36% reduction in time spent drafting emails. AI tools are now handling account research, list building, and CRM logging automatically. Other tasks like scheduling meetings, transcribing calls, and timing follow-ups are also shifting to AI. Tools like ChatGPT, Claude, and Perplexity help reps get information quickly, while MCP connectors bring live data into systems like Salesforce and HubSpot. Despite this automation, humans will still handle live negotiations and other tasks that require trust and personal connection.

Study reveals how language models use internal knowledge

Researchers studied how large language models like Qwen, Llama, and Gemma retrieve and use their internal knowledge to answer questions. The study used layerwise interventions to see how the models process information at different stages. Results showed that the models rely on specific request directions early on before switching to stored content later. The Gemma model showed a unique pattern where routing and content profiles overlapped in the middle layers. In contrast, the Llama model did not show a sustained effect from request directions under the same conditions. These findings help scientists understand how different models handle information flow during the question-answering process.

House Democrats urge Speaker Johnson to cancel recess

A group of House Democratic lawmakers is asking Speaker Mike Johnson to cancel an upcoming recess. They want the chamber to meet immediately to pass new safeguards for artificial intelligence. The lawmakers describe the risks posed by advanced AI systems as catastrophic. This pressure comes as Senate negotiators also debate similar legislation to ensure AI safety. The Democrats believe urgent action is needed to prevent potential dangers from powerful AI models. The situation highlights the growing concern among politicians about regulating technology before it causes harm.

Altman and Musk support AI slowdown call

Sam Altman and Elon Musk have joined forces to support Dario Amodei's warning about artificial intelligence. These tech leaders agree that AI is developing too quickly for humans to manage safely. Amodei, a former Google engineer, has long argued that rapid growth could lead to dangerous outcomes. Both Altman, who leads Y Combinator, and Musk, CEO of SpaceX and Tesla, believe the industry needs to slow down. Their united stance highlights growing concerns among top figures about the potential risks of advanced AI technology.

Trump warns US must win AI race against China

President Donald Trump has commented on the artificial intelligence debate and emphasized the need for the United States to compete with China. He believes it is crucial for the US to win the race in developing this technology. The article notes his take on how important this competition is for the country's future. Trump's statement reflects the ongoing global focus on AI development and national security.
