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.

2 Reasons to Watch YELP and 1 to Stay Cautious

YELP Cover Image

Yelp has been treading water for the past six months, recording a small return of 1.8% while holding steady at $34.45. The stock also fell short of the S&P 500’s 22.9% gain during that period.

Given the weaker price action, is now a good time to buy YELP? Or should investors expect a bumpy road ahead? Find out in our full research report, it’s free for active Edge members.

Why Does Yelp Spark Debate?

Founded by PayPal alumni Jeremy Stoppelman and Russel Simmons, Yelp (NYSE: YELP) is an online platform that helps people discover local businesses through crowd-sourced reviews.

Two Positive Attributes:

1. Elite Gross Margin Powers Best-In-Class Business Model

A company’s gross profit margin has a significant impact on its ability to exert pricing power, develop new products, and invest in marketing. These factors can determine the winner in a competitive market.

For social network businesses like Yelp, gross profit tells us how much money the company gets to keep after covering the base cost of its products and services, which typically include customer service, data center, and other infrastructure expenses.

Yelp’s gross margin is one of the highest in the consumer internet sector, an output of its asset-lite business model and strong pricing power. It also enables the company to fund large investments in product and marketing during periods of rapid growth to achieve higher profits in the future. As you can see below, it averaged an elite 91.1% gross margin over the last two years. Said differently, roughly $91.09 was left to spend on selling, marketing, and R&D for every $100 in revenue.

2. Outstanding Long-Term EPS Growth

We track the change in earnings per share (EPS) because it highlights whether a company’s growth is profitable.

Yelp’s EPS grew at an astounding 28.4% compounded annual growth rate over the last three years, higher than its 9.1% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.

One Reason to be Careful:

Growth in Customer Spending Lags Peers

Average revenue per user (ARPU) is a critical metric to track because it measures how much the company earns from the ads shown to its users. ARPU can also be a proxy for how valuable advertisers find Yelp’s audience and its ad-targeting capabilities.

Yelp’s ARPU growth has been mediocre over the last two years, averaging 3.5%. This raises questions about its platform’s health and ability to engage its users effectively. Yelp ARPU

Final Judgment

Yelp has huge potential even though it has some open questions. With its shares underperforming the market lately, the stock trades at 6.3× forward EV/EBITDA (or $34.45 per share).
