About Cabling Installation & Maintenance:

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.

1 Safe-and-Steady Stock with Impressive Fundamentals and 2 to Turn Down

KMX Cover Image

Stability is great, but low-volatility stocks may struggle to deliver market-beating returns over time as they sometimes underperform during bull markets.

Choosing the wrong investments can cause you to fall behind, which is why we started StockStory - to separate the winners from the losers. That said, here is one low-volatility stock that could offer consistent gains and two that may not keep up.

Two Stocks to Sell:

CarMax (KMX)

Rolling One-Year Beta: 0.52

Known for its transparent, customer-centric approach and wide selection of vehicles, Carmax (NYSE: KMX) is the largest automotive retailer in the United States.

Why Should You Dump KMX?

  1. Weak same-store sales trends over the past two years suggest there may be few opportunities in its core markets to open new locations
  2. Gross margin of 10.8% is below its competitors, leaving less money for marketing and promotions
  3. 16× net-debt-to-EBITDA ratio shows it’s overleveraged and increases the probability of shareholder dilution if things turn unexpectedly

CarMax’s stock price of $66.80 implies a valuation ratio of 17x forward P/E. To fully understand why you should be careful with KMX, check out our full research report (it’s free).

Lumen (LUMN)

Rolling One-Year Beta: 0.64

With approximately 350,000 route miles of fiber optic cable spanning North America and the Asia Pacific, Lumen Technologies (NYSE: LUMN) operates a vast fiber optic network that provides communications, cloud connectivity, security, and IT solutions to businesses and consumers.

Why Do We Steer Clear of LUMN?

  1. Products and services are facing significant end-market challenges during this cycle as sales have declined by 9.4% annually over the last five years
  2. Free cash flow margin shrank by 7.5 percentage points over the last five years, suggesting the company is consuming more capital to stay competitive
  3. Shrinking returns on capital from an already weak position reveal that neither previous nor ongoing investments are yielding the desired results

Lumen is trading at $4.33 per share, or 1.3x forward EV-to-EBITDA. Read our free research report to see why you should think twice about including LUMN in your portfolio.

One Stock to Buy:

BellRing Brands (BRBR)

Rolling One-Year Beta: 0.79

Spun out of Post Holdings in 2019, Bellring Brands (NYSE: BRBR) offers protein shakes, nutrition bars, and other products under the PowerBar, Premier Protein, and Dymatize brands.

Why Do We Love BRBR?

  1. Unit sales were phenomenal over the past two years, showing demand is robust and retailers can’t stock enough of its products
  2. Earnings per share grew by 28% annually over the last three years, massively outpacing its peers
  3. Market-beating returns on capital illustrate that management has a knack for investing in profitable ventures

At $57.26 per share, BellRing Brands trades at 24x forward P/E. Is now a good time to buy? Find out in our full research report, it’s free.
