About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

Carvana, Netflix, Duolingo, Robinhood, and Chegg Shares Plummet, What You Need To Know

CVNA Cover Image

What Happened?

A number of stocks fell in the afternoon session after investor apprehension intensified ahead of a key policy speech and perplexing inflation signals clouded the economic outlook, leading to a wider market retreat from growth-oriented stocks. 

The downturn in the market was largely attributed to a significant sell-off in megacap tech and chipmaker shares. Nvidia, Advanced Micro Devices (AMD), and Broadcom all saw notable drops, dragging down the VanEck Semiconductor ETF. Other major tech-related companies like Tesla, Meta Platforms, and Netflix were also under pressure. A key reason for this trend is that much of the recent market gains have been concentrated in the "AI trade," which includes these large technology and semiconductor companies. So this could also mean that some investors are locking in some gains ahead of more definitive feedback from the Fed.

The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks.

Among others, the following stocks were impacted:

Zooming In On Duolingo (DUOL)

Duolingo’s shares are extremely volatile and have had 34 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.

The previous big move we wrote about was 1 day ago when the stock gained 13.5% on the news that it received bullish analyst coverage, including an upgrade from KeyBanc and a new 'Buy' rating from Citi. KeyBanc Capital Markets upgraded the stock to “Overweight” from “Sector Weight” and set a $460 price target, implying significant upside. Analysts at KeyBanc stated that the recent AI backlash was just “a bump in the road” and that fears of AI hurting the digital-education app are “overblown.” The firm highlighted Duolingo's product improvements and viral marketing as potential drivers for growth. 

Adding to the positive sentiment, Citi initiated coverage with a “Buy” rating and a $400 price target. Citi’s analysts argued that the stock price overstates AI-related risks and pointed to the company’s potential for long-term growth. This wave of analyst confidence follows Duolingo's strong second-quarter results reported earlier in August, where it beat estimates and raised its full-year revenue forecast.

Duolingo is up 4.5% since the beginning of the year, but at $340.66 per share, it is still trading 37% below its 52-week high of $540.68 from May 2025. Investors who bought $1,000 worth of Duolingo’s shares at the IPO in July 2021 would now be looking at an investment worth $2,451.

Today’s young investors won’t have read the timeless lessons in Gorilla Game: Picking Winners In High Technology because it was written more than 20 years ago when Microsoft and Apple were first establishing their supremacy. But if we apply the same principles, then enterprise software stocks leveraging their own generative AI capabilities may well be the Gorillas of the future. So, in that spirit, we are excited to present our Special Free Report on a profitable, fast-growing enterprise software stock that is already riding the automation wave and looking to catch the generative AI next.
