In accordance with the announced upcoming communication services sector change, the new Communication Services Select Sector Index is now live. The select sectors are based on the Global Industry Classification Standard (GICS®) but have different construction rules than the sectors of the S&P 500. In the Select Sectors, each index is made up of all stocks in the GICS sector unless otherwise noted in the table below.Source: S&P Dow Jones Indices. S&P U.S. Indices Methodology. 1 The Communication Services Select Sector Index reflects the changes in the GICS structure effective in September 2018. For more information regarding the composition of the Communication Services Sector, please refer to Appendix D. S&P Dow Jones Indices has created back calculated history for the Communication Services Select Sector Index based on the securities in the headline S&P 500 that would have hypothetically been classified as GICS Code 50 at that time under this new structure. 2 In order to align with the GICS structure changes effective in September 2018, S&P DJI will remove stocks classified as Communication Services (GICS Code 50) from the Technology Select Sector Index.
Furthermore, the weighting of the constituents inside the select sectors follows the capped market capitalization weighting. In short, there is a quarterly rebalancing where each company is float adjusted market cap weighted with capping to limit companies to under 25% each, and to limit the sum of companies with weights greater than 4.8% to under 50% of the index (The full details of the weighting can be found in the methodology on pages 12-13).
The new sector map is discussed in detail in this post, but as a reminder is shown below:
