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.

3 Healthcare Stocks with Questionable Fundamentals

ZBH Cover Image

From novel pharmaceuticals to telemedicine, most healthcare companies are on a mission to drive better patient outcomes. But speed bumps such as inventory destockings have persisted in the wake of COVID-19, and over the past six months, the industry has pulled back by 6.3%. This drop is a far cry from the S&P 500’s 6.2% ascent.

While some businesses have durable competitive advantages that enable them to grow consistently, the odds aren’t great for the ones we’re analyzing today. Keeping that in mind, here are three healthcare stocks we’re steering clear of.

Zimmer Biomet (ZBH)

Market Cap: $18.53 billion

With a history dating back to 1927 and a presence in over 100 countries worldwide, Zimmer Biomet (NYSE: ZBH) designs and manufactures orthopedic products including knee and hip replacements, surgical tools, and robotic technologies for joint reconstruction and spine surgeries.

Why Does ZBH Give Us Pause?

  1. Sales were flat over the last five years, indicating it’s failed to expand this cycle
  2. Weak constant currency growth over the past two years indicates challenges in maintaining its market share
  3. Low returns on capital reflect management’s struggle to allocate funds effectively

At $93.67 per share, Zimmer Biomet trades at 11.3x forward P/E. If you’re considering ZBH for your portfolio, see our FREE research report to learn more.

Select Medical (SEM)

Market Cap: $1.95 billion

With a nationwide network spanning 46 states and over 2,700 healthcare facilities, Select Medical (NYSE: SEM) operates critical illness recovery hospitals, rehabilitation hospitals, outpatient rehabilitation clinics, and occupational health centers across the United States.

Why Are We Out on SEM?

  1. Declining admissions over the past two years show it’s struggled to increase its sales volumes and had to rely on price increases
  2. Sales are expected to decline once again over the next 12 months as it continues working through a challenging demand environment
  3. Free cash flow margin shrank by 13.2 percentage points over the last five years, suggesting the company is consuming more capital to stay competitive

Select Medical’s stock price of $15.14 implies a valuation ratio of 13x forward P/E. Read our free research report to see why you should think twice about including SEM in your portfolio.

RadNet (RDNT)

Market Cap: $4.22 billion

With over 350 imaging facilities across seven states and a growing artificial intelligence division, RadNet (NASDAQ: RDNT) operates a network of outpatient diagnostic imaging centers across the United States, offering services like MRI, CT scans, PET scans, mammography, and X-rays.

Why Does RDNT Fall Short?

  1. Revenue base of $1.87 billion puts it at a disadvantage compared to larger competitors exhibiting economies of scale
  2. Free cash flow margin dropped by 3.9 percentage points over the last five years, implying the company became more capital intensive as competition picked up
  3. Underwhelming 6.4% return on capital reflects management’s difficulties in finding profitable growth opportunities

RadNet is trading at $56.20 per share, or 106.1x forward P/E. Dive into our free research report to see why there are better opportunities than RDNT.
