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 Instacart (CART) Stock Is Falling Today

CART Cover Image

What Happened?

Shares of online grocery delivery platform Instacart (NASDAQ: CART) fell 6.4% in the afternoon session after BTIG downgraded the stock to Neutral from Buy, citing intensifying competitive pressure. 

The analyst noted that in just two weeks, grocers representing over 25% of Instacart's gross order value had signed partnerships with rivals like Amazon, DoorDash, or Uber. This raised questions about the company's growth path. The downgrade followed news from the previous session that competitor DoorDash and supermarket giant Kroger were expanding their grocery delivery partnership. This directly challenged Instacart, as Kroger was its third-largest customer and accounted for over 10% of its gross transaction value.

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 Instacart? Access our full analysis report here, it’s free.

What Is The Market Telling Us

Instacart’s shares are quite volatile and have had 16 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.

The previous big move we wrote about was about 23 hours ago when the stock dropped 8.7% on the news that reports revealed that rival DoorDash Inc. and supermarket giant Kroger Co. are expanding their partnership for grocery delivery starting next month, intensifying competition. 

The news directly impacts Instacart as Kroger is its third-largest customer, accounting for over 10% of the company's gross transaction value. Wedbush analysts noted the move "directly challenges Instacart's position among intermediaries," adding to Wall Street's concerns about the company's ability to compete. This development amplifies existing competitive pressures from major players like Amazon and Walmart, who have been making their own aggressive pushes into grocery delivery. In recent months, analysts have already cited heightened competition from Amazon's expanding services as a reason for concern, suggesting Instacart's market share is at risk of eroding in an increasingly crowded market.

Instacart is down 17% since the beginning of the year, and at $35.74 per share, it is trading 32.8% below its 52-week high of $53.15 from February 2025. Investors who bought $1,000 worth of Instacart’s shares at the IPO in September 2023 would now be looking at an investment worth $1,060.

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.
