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 Unprofitable Stocks with Warning Signs

By: StockStory

AI Cover Image

Unprofitable companies can burn through cash quickly, leaving investors exposed if they fail to turn things around. Without a clear path to profitability, these businesses risk running out of capital or relying on dilutive fundraising.

A lack of profits can lead to trouble, but StockStory helps you identify the businesses that stand a chance of making it through. That said, here are three unprofitable companiesto avoid and some better opportunities instead.

C3.ai (AI)

Trailing 12-Month GAAP Operating Margin: -101%

Named after the three Cs of its original focus—carbon, cloud computing, and customer relationship management—C3.ai (NYSE: AI) provides enterprise AI software that helps organizations develop, deploy, and operate large-scale artificial intelligence applications across various industries.

Why Should You Sell AI?

  1. 11.9% annual revenue growth over the last three years was slower than its software peers
  2. Gross margin of 56.6% reflects its high servicing costs
  3. Cash-burning history makes us doubt the long-term viability of its business model

C3.ai is trading at $17.35 per share, or 7.6x forward price-to-sales. Read our free research report to see why you should think twice about including AI in your portfolio.

Kraft Heinz (KHC)

Trailing 12-Month GAAP Operating Margin: -27.3%

The result of a 2015 mega-merger between Kraft and Heinz, Kraft Heinz (NASDAQ: KHC) is a packaged foods giant whose products span coffee to cheese to packaged meat.

Why Do We Pass on KHC?

  1. Shrinking unit sales over the past two years suggest it might have to lower prices to stimulate growth
  2. Day-to-day expenses have swelled relative to revenue over the last year as its operating margin fell by 41.7 percentage points
  3. Below-average returns on capital indicate management struggled to find compelling investment opportunities, and its shrinking returns suggest its past profit sources are losing steam

Kraft Heinz’s stock price of $25.80 implies a valuation ratio of 9.8x forward P/E. To fully understand why you should be careful with KHC, check out our full research report (it’s free).

Fluence Energy (FLNC)

Trailing 12-Month GAAP Operating Margin: -1.1%

Pioneering the use of lithium-ion batteries for grid storage, Fluence (NASDAQ: FLNC) helps store renewable energy sources with battery systems.

Why Are We Cautious About FLNC?

  1. Competitive supply chain dynamics and steep production costs are reflected in its low gross margin of 7.2%
  2. Free cash flow margin dropped by 6.4 percentage points over the last five years, implying the company increased its investment activities to fend off competitors
  3. Short cash runway increases the probability of a capital raise that dilutes existing shareholders

At $7.48 per share, Fluence Energy trades at 102.5x forward P/E. Check out our free in-depth research report to learn more about why FLNC doesn’t pass our bar.
