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.

3 High-Flying Stocks Skating on Thin Ice

MMI Cover Image

"You get what you pay for" often applies to expensive stocks with best-in-class business models and execution. While their quality can sometimes justify the premium, they typically experience elevated volatility during market downturns when expectations change.

Determining whether a company’s quality justifies its price causes headaches for nearly all investors, which is why we started StockStory - to help you separate the real opportunities from the speculative ones. Keeping that in mind, here are three high-flying stocks where the price is not right and some other investments you should look into instead.

Marcus & Millichap (MMI)

Forward P/E Ratio: 297.1x

Founded in 1971, Marcus & Millichap (NYSE: MMI) specializes in commercial real estate investment sales, financing, research, and advisory services.

Why Is MMI Risky?

  1. Annual sales declines of 3.2% for the past five years show its products and services struggled to connect with the market
  2. Cash-burning history makes us doubt the long-term viability of its business model
  3. Shrinking returns on capital suggest that increasing competition is eating into the company’s profitability

Marcus & Millichap is trading at $29.71 per share, or 297.1x forward P/E. If you’re considering MMI for your portfolio, see our FREE research report to learn more.

NN (NNBR)

Forward P/E Ratio: 316.1x

Formerly known as Nuturn, NN (NASDAQ: NNBR) provides metal components, bearings, and plastic and rubber components to the automotive, aerospace, medical, and industrial sectors.

Why Do We Think NNBR Will Underperform?

  1. Annual sales declines of 1.3% for the past five years show its products and services struggled to connect with the market during this cycle
  2. Sales were less profitable over the last five years as its earnings per share fell by 16.9% annually, worse than its revenue declines
  3. Cash-burning history and the downward spiral in its margin profile make us wonder if it has a viable business model

At $2.09 per share, NN trades at 316.1x forward P/E. Read our free research report to see why you should think twice about including NNBR in your portfolio.

CoStar (CSGP)

Forward P/E Ratio: 73.9x

With a research department that makes over 10,000 property updates daily to its 35-year-old database, CoStar Group (NASDAQ: CSGP) provides comprehensive real estate data, analytics, and online marketplaces for commercial and residential properties in the U.S. and U.K.

Why Are We Wary of CSGP?

  1. Day-to-day expenses have swelled relative to revenue over the last five years as its adjusted operating margin fell by 23.7 percentage points
  2. Incremental sales over the last five years were much less profitable as its earnings per share fell by 4% annually while its revenue grew
  3. Free cash flow margin dropped by 16.6 percentage points over the last five years, implying the company became more capital intensive as competition picked up

CoStar’s stock price of $78.52 implies a valuation ratio of 73.9x forward P/E. To fully understand why you should be careful with CSGP, check out our full research report (it’s free).
