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.

Why CarMax (KMX) Shares Are Falling Today

KMX Cover Image

What Happened?

Shares of used automotive vehicle retailer Carmax (NYSE: KMX) fell 23.4% in the morning session after the company reported third-quarter 2025 results that significantly missed Wall Street's expectations. The company posted earnings of $0.64 per share, which fell far short of the anticipated $1.03 per share and marked a 24.7% drop from the previous year. Revenue also disappointed, coming in at $6.59 billion, below the consensus estimate of $7.07 billion and representing a 6% decrease year-over-year. The poor performance was driven by weakening demand, as same-store sales fell 7.1%. Adding to concerns, profitability worsened, with the operating margin declining to 1.8% from 2.9% in the same quarter last year.

The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks. Is now the time to buy CarMax? Access our full analysis report here, it’s free.

What Is The Market Telling Us

CarMax’s shares are not very volatile and have only had 7 moves greater than 5% over the last year. Moves this big are rare for CarMax and indicate this news significantly impacted the market’s perception of the business.

The biggest move we wrote about over the last year was 6 months ago when the stock dropped 19.8% on the news that the company reported underwhelming Q1 2025 (fiscal Q4 2025) results. 

Its EBITDA missed significantly and its EPS fell short of Wall Street's estimates. More troubling, the company suspended its long-term growth guidance, citing macroeconomic uncertainty, a move that signaled management's reduced visibility and confidence in the future growth trajectory. Overall, this quarter could have been better.

CarMax is down 44.1% since the beginning of the year, and at $45.42 per share, it is trading 49.1% below its 52-week high of $89.19 from February 2025. Investors who bought $1,000 worth of CarMax’s shares 5 years ago would now be looking at an investment worth $483.04.

Unless you’ve been living under a rock, it should be obvious by now that generative AI is going to have a huge impact on how large corporations do business. While Nvidia and AMD are trading close to all-time highs, we prefer a lesser-known (but still profitable) semiconductor stock benefiting from the rise of AI.
