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 Enphase (ENPH) Shares Are Sliding Today

ENPH Cover Image

What Happened?

Shares of home energy technology company Enphase (NASDAQ: ENPH) fell 1.4% in the afternoon session after the major indices continued to retreat (Nasdaq -1.5%, S&P 500 -1.2%) amid profit-taking and renewed concerns about tariffs. 

Investors reacted to a federal court ruling that most of President Trump's global tariffs were illegal, raising uncertainty over trade policy and the fiscal impact of potential refunds. Rising Treasury yields added to the pressure, with the 10-year climbing above 4.2% and the 30-year nearing 5%, intensifying worries about stretched equity valuations. September's historically weak track record for stocks further dampened sentiment, leaving traders cautious ahead of the jobs report later in the week and the Federal Reserve's upcoming rate decision.

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

What Is The Market Telling Us

Enphase’s shares are extremely volatile and have had 46 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 7 days ago when the stock gained 3.5% on the news that Jefferies upgraded the stock to Hold from Underperform and raised its price target to $36 from $28. The upgrade provided a direct boost to the solar technology company's shares. The positive move was also supported by a backdrop of favorable news for the broader solar and renewable energy sector. Reports indicated that India installed 14.3GW of new utility-scale solar capacity in the first half of 2025, a 49% increase year-on-year. In the U.S., New Jersey's governor signed new legislation aimed at increasing energy storage and community solar projects. Additionally, fellow solar company FTC Solar announced a significant 1GW tracker supply agreement, signaling robust industry demand.

Enphase is down 48.4% since the beginning of the year, and at $36.82 per share, it is trading 69.3% below its 52-week high of $119.74 from September 2024. Investors who bought $1,000 worth of Enphase’s shares 5 years ago would now be looking at an investment worth $478.06.
