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 Lumen (LUMN) Stock Is Falling Today

LUMN Cover Image

What Happened?

Shares of telecommunications infrastructure company Lumen Technologies (NYSE: LUMN) fell 3.9% in the morning session after the company announced its Chief Accounting Officer and Controller, Andrea Genschaw, will resign effective September 23, 2025. 

Ms. Genschaw is leaving to take on a Chief Financial Officer role at another publicly traded company, and her departure is not the result of any disagreement with Lumen. In line with a long-term succession plan, the company's Board of Directors appointed Donald Holt, an internal finance leader, as her successor. 

The executive change occurs amidst a challenging financial outlook for the company. Analysts estimate Lumen's revenue will decrease by 3.8% per year over the next three years, contrasting sharply with expectations for significant growth across the rest of the telecom industry. This backdrop of declining revenue may make investors more sensitive to changes in key leadership positions.

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 Lumen? Access our full analysis report here, it’s free.

What Is The Market Telling Us

Lumen’s shares are extremely volatile and have had 48 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 5 days ago when the stock gained 0.9% on the news that the Consumer Price Index (CPI) report bolstered expectations for a Federal Reserve interest rate cut despite showing persistent inflation. 

The August CPI data, a key measure of inflation, showed prices rose 2.9% annually, slightly more than economists expected. While inflation remains above the Federal Reserve's 2% target, investors were focusing on other signs of a cooling economy, particularly a weakening labor market. 

As a result, the market widely anticipated that the Fed would cut interest rates at its September meeting to support the economy. Investors priced in multiple rate cuts by year-end, which boosted market sentiment and sent Treasury yields lower.

Lumen is down 0.8% since the beginning of the year, and at $5.57 per share, it is trading 45% below its 52-week high of $10.12 from November 2024. Investors who bought $1,000 worth of Lumen’s shares 5 years ago would now be looking at an investment worth $505.91.

Here at StockStory, we certainly understand the potential of thematic investing. Diverse winners from Microsoft (MSFT) to Alphabet (GOOG), Coca-Cola (KO) to Monster Beverage (MNST) could all have been identified as promising growth stories with a megatrend driving the growth. So, in that spirit, we’ve identified a relatively under-the-radar profitable growth stock benefiting from the rise of AI, available to you FREE via this link.
