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.

Why MercadoLibre (MELI) Shares Are Sliding Today

MELI Cover Image

What Happened?

Shares of latin American e-commerce and fintech company MercadoLibre (NASDAQ: MELI) fell 7% in the afternoon session after investors locked in some profits amid broader macroeconomic concerns following a significant run since the start of the year. 

Given the absence of any company-specific update, this move was likely amplified by a general "risk-off" sentiment in the market, fueled by the uncertainty of a potential U.S. government shutdown. Furthermore, a report showing an unexpected drop in U.S. consumer confidence added to the bearish mood for stocks.

The shares closed the day at $2,337, down 6.5% from previous close.

The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks. Is now the time to buy MercadoLibre? Access our full analysis report here, it’s free.

What Is The Market Telling Us

MercadoLibre’s shares are not very volatile and have only had 9 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful, although it might not be something that would fundamentally change its perception of the business.

The biggest move we wrote about over the last year was 11 months ago when the stock dropped 16.3% on the news that the company reported weaker third-quarter earnings. 

The main reason was that it missed on operating income margin because it ramped up investments in its credit and logistics businesses. Ramping up loan originations leads to the recognition of the allowance for doubtful accounts upfront (the expected losses on the loans). However, the new loan originations came from credit cards and moving up-market to higher-quality customers. Because these new accounts have lower default risk, the yields are lower and result in a lower blended NIMAL spread (aka margins). 

However, the new loans are additive to overall profit dollars, lower the risk of the broader credit portfolio, and increase MELI's market share and stickiness/wallet share with customers. 

On the other hand, MercadoLibre delivered impressive revenue growth this quarter. Overall, the stock is reacting to the bottom line miss.

MercadoLibre is up 32.7% since the beginning of the year, but at $2,343 per share, it is still trading 10.4% below its 52-week high of $2,614 from June 2025. Investors who bought $1,000 worth of MercadoLibre’s shares 5 years ago would now be looking at an investment worth $2,164.

Unless you’ve been living under a rock, it should be obvious by now that generative AI is going to have a huge impact on how large corporations do business. While Nvidia and AMD are trading close to all-time highs, we prefer a lesser-known (but still profitable) semiconductor stock benefiting from the rise of AI.
