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.

Dollar General (DG): Buy, Sell, or Hold Post Q1 Earnings?

DG Cover Image

What a fantastic six months it’s been for Dollar General. Shares of the company have skyrocketed 48.4%, hitting $112.99. This was partly due to its solid quarterly results, and the run-up might have investors contemplating their next move.

Is now the time to buy Dollar General, or should you be careful about including it in your portfolio? Dive into our full research report to see our analyst team’s opinion, it’s free.

Why Is Dollar General Not Exciting?

We’re happy investors have made money, but we're sitting this one out for now. Here are three reasons why DG doesn't excite us and a stock we'd rather own.

1. Flat Same-Store Sales Indicate Weak Demand

Same-store sales show the change in sales for a retailer's e-commerce platform and brick-and-mortar shops that have existed for at least a year. This is a key performance indicator because it measures organic growth.

Dollar General’s demand within its existing locations has barely increased over the last two years as its same-store sales were flat.

2. Low Gross Margin Reveals Weak Structural Profitability

At StockStory, we prefer high gross margin businesses because they indicate pricing power or differentiated products, giving the company a chance to generate higher operating profits.

Dollar General has bad unit economics for a retailer, signaling it operates in a competitive market and lacks pricing power because its inventory is sold in many places. As you can see below, it averaged a 29.9% gross margin over the last two years. Said differently, Dollar General had to pay a chunky $70.13 to its suppliers for every $100 in revenue.

3. High Debt Levels Increase Risk

Debt is a tool that can boost company returns but presents risks if used irresponsibly. As long-term investors, we aim to avoid companies taking excessive advantage of this instrument because it could lead to insolvency.

Dollar General’s $17.02 billion of debt exceeds the $850 million of cash on its balance sheet. Furthermore, its 5× net-debt-to-EBITDA ratio (based on its EBITDA of $2.97 billion over the last 12 months) shows the company is overleveraged.

Dollar General Net Debt Position

At this level of debt, incremental borrowing becomes increasingly expensive and credit agencies could downgrade the company’s rating if profitability falls. Dollar General could also be backed into a corner if the market turns unexpectedly – a situation we seek to avoid as investors in high-quality companies.

We hope Dollar General can improve its balance sheet and remain cautious until it increases its profitability or pays down its debt.

Final Judgment

Dollar General isn’t a terrible business, but it isn’t one of our picks. After the recent rally, the stock trades at 19.4× forward P/E (or $112.99 per share). Beauty is in the eye of the beholder, but we don’t really see a big opportunity at the moment. We're pretty confident there are superior stocks to buy right now.
