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.

Running at a loss can be a red flag. Many of these businesses face mounting challenges as competition increases and funding becomes harder to secure.

Finding the right unprofitable companies is difficult, which is why we started StockStory - to help you navigate the market. That said, here are three unprofitable companiesthat don’t make the cut and some better opportunities instead.

Zillow (ZG)

Trailing 12-Month GAAP Operating Margin: -7%

Founded by Expedia co-founders Lloyd Frink and Rich Barton, Zillow (NASDAQ: ZG) is the leading U.S. online real estate marketplace.

Why Should You Sell ZG?

  1. Annual revenue declines of 7.6% over the last five years indicate problems with its market positioning
  2. Persistent operating margin losses suggest the business manages its expenses poorly
  3. Eroding returns on capital from an already low base indicate that management’s recent investments are destroying value

Zillow is trading at $66.10 per share, or 35.3x forward P/E. Read our free research report to see why you should think twice about including ZG in your portfolio.

Roku (ROKU)

Trailing 12-Month GAAP Operating Margin: -4.8%

Spun out from Netflix, Roku (NASDAQ: ROKU) makes hardware players that offer access to various online streaming TV services.

Why Does ROKU Fall Short?

  1. Decision to emphasize platform growth over monetization has contributed to 1.4% annual declines in its average revenue per user
  2. Efficiency has decreased over the last few years as its EBITDA margin fell by 7.1 percentage points
  3. Incremental sales over the last three years were much less profitable as its earnings per share fell by 36.7% annually while its revenue grew

At $80.99 per share, Roku trades at 32.5x forward EV/EBITDA. Check out our free in-depth research report to learn more about why ROKU doesn’t pass our bar.

Allegro MicroSystems (ALGM)

Trailing 12-Month GAAP Operating Margin: -2.7%

The result of a spinoff from Sanken in Japan, Allegro MicroSystems (NASDAQ: ALGM) is a designer of power management chips and distance sensors used in electric vehicles and data centers.

Why Are We Out on ALGM?

  1. Products and services are facing significant end-market challenges during this cycle as sales have declined by 13.7% annually over the last two years
  2. Earnings per share have dipped by 16.8% annually over the past four years, which is concerning because stock prices follow EPS over the long term
  3. Capital intensity has ramped up over the last five years as its free cash flow margin decreased by 10.5 percentage points

Allegro MicroSystems’s stock price of $30.48 implies a valuation ratio of 61.3x forward P/E. Dive into our free research report to see why there are better opportunities than ALGM.
