GICS Core

GICS Core is the top-level perspective within the Sector Intelligence of the G11 General Industry Compass System. This level is deliberately set at a distance and provides an overarching view of the central structures of the global economy.
The focus of GICS Core as the TIER 1 level of the G11 General Industry Compass System is on broadly defined economic sectors as stable organizational units. Instead of detailed subdivisions, the focus is on classifying economic activities into a few, sustainable categories that serve as a long-term frame of reference. The helicopter perspective of GICS Core opens up space for fundamental questions: How do weights shift between sectors? Which structures characterize entire sectors across economic cycles? And which sectoral dependencies only become visible from a distance?

The focus of GICS Core as the TIER 1 level of the G11 General Industry Compass System is on broadly defined economic sectors as stable classification units. Instead of detailed subdivisions, the aim is to classify economic activities into a few viable categories that serve as a long-term frame of reference.

The helicopter perspective of GICS Core opens up space for fundamental questions:

  • How do weights shift between sectors?
  • What structures shape entire industries across economic cycles?
  • And which sectoral dependencies only become visible from a distance?

The Communication Services sector bundles companies that enable, distribute or monetize information, content and digital interaction. The focus is on communication networks, media offerings and platforms that connect people, companies and markets. Communication Services is a mediation and reach sector. The companies grouped here do not primarily provide technical foundations, but rather ensure that content can be transported, made visible and used. Communication is understood both as an infrastructure service and as a content offering. The sector is characterized by its dual function. On the one hand, it creates the conditions for exchange, networking and accessibility. On the other hand, it shapes perception, opinion-forming and consumption of information and entertainment. Reach, attention and length of use are key factors for economic success. The sector is strongly influenced by user behavior and media usage. Changes in consumer habits, technological developments and new formats have a direct impact on business models. At the same time, network effects arise that can give individual providers particular market power. Communication Services operates at the interface between technology, content and society. While technical components provide stability and scalability, content, formats and interaction determine acceptance and relevance. Competition is therefore not just about technology, but above all about attention. Within GICS Eleven, Communication Services forms the counterpart to Information Technology in terms of content. While IT provides the technical basis, Communication Services stands for the use, distribution and impact of digital and media content. The sector serves as a frame of reference for topics relating to media, networking and the digital public sphere.

GICS Core acts as a strategic thinking space within the General Industry Compass system. The perspective provides orientation without simplifying and creates a common basis on which further perspectives - such as Trending or Microsectors - can be built upon in a targeted manner.


GICS Core is deliberately designed as an introductory and reference level.
The perspective is aimed at users who initially want to get their bearings, grasp interrelationships and understand sectoral structures in a broader economic context without committing to detailed analyses at an early stage.

As an organizing framework, GICS Core is particularly suitable:

  • as a conceptual haven of peace within the GICS family,
  • as a common reference level for cross-references to in-depth content,
  • as well as a conceptual starting point for further perspectives such as GICS Trending or GICS Microsectors.

The level thus serves less for operational analysis and more for strategic classification - it creates an overview, promotes systemic thinking and lays the foundation for in-depth discussion along downstream perspectives.
