The communication services sector is undergoing a significant reshuffle, with major players making bold moves to stay ahead in the game. AT&T's acquisition of Time Warner is a prime example of this trend.
The sector's transformation is largely driven by the increasing demand for high-speed internet and streaming services. This shift has led to a surge in investments in 5G infrastructure and content creation.
Companies like Disney and Comcast are expanding their streaming offerings to compete with the likes of Netflix and Amazon Prime. This has resulted in a significant increase in content production costs, which is being passed on to consumers through higher subscription fees.
The sector's reshuffle is also being fueled by the growing importance of cloud computing and cybersecurity services.

Why It Matters
The GICS reclassification is a reminder that the lines between different sectors are blurring, and it's time to acknowledge this convergence.
Companies like Verizon and Facebook are no longer just telecoms or social networks, but also media companies, making it harder to categorize them.
The GICS reclassification aims to reflect where companies earn most of their revenues from, which is a crucial aspect for investors.
The real estate sector's performance gap with Financials after its breakout in 2016 is a telling example of how sector grouping matters.
Investors focused on very different fundamentals for these once-unified sectors, resulting in a 39% rally for Financials versus a 0.5% return for Real Estate.
This performance gap suggests that sector grouping has a significant impact on investor decisions and market performance.

Stock Market Impact
The stock market impact of the communication services sector reshuffle is relatively minor, with Vanguard temporarily creating custom benchmarks for its Consumer Discretionary Index Fund, Information Technology Index Fund, and Telecommunication Services Index Fund.
The changes don't require any action from investors, as Vanguard is doing the heavy lifting behind the scenes. BlackRock is overhauling its iShares Global Telecom ETF to become the iShares Global Comm Services ETF, and changing the kinds of companies it tracks accordingly.
About 10% of the S&P 500 will be affected by the reclassification, but investors need not do much on the drawing board. Some stocks are getting moved around, but their weights on the index are not, so the reshuffle itself may not be a big market mover.
Index investors won't be impacted by the sector shuffle, as the price movements of the capitalization-weighted S&P 500 will still rise and fall based on the daily movements of the same 500 stocks.
The weighting of tech stocks will shrink to roughly 20 percent from about 26 percent of the large-company stock index, but this won't necessarily be a bad thing.
Sector Changes
The new Communication Services sector is a game-changer for investors. The sector replaces the old Telecommunication Services sector and will include companies from the Information Technology sector that facilitate communication, such as Alphabet and Facebook.
This change will impact some big-name stocks, including AT&T and Verizon, which will remain in the new sector, but will also add new companies like Disney and Comcast Corp. The new sector will have 26 constituents with a total market cap of $2.35 trillion.

The Communication Services Select Sector Index, which tracks the new sector, has already been launched by S&P Dow Jones Indices. The index has a cumulative return of 143.5 percent through May 16, 2018, with annualized performance of 14.2 percent over three years.
The new sector will have a 10 percent weighting in the S&P 500, making it a significant part of the index. It will also be less defensive than the old telecom sector, with a much smaller dividend yield.
Two stocks, Facebook and Alphabet, will account for 45 percent of the new index, making it a concentrated sector. On the other hand, the tech sector will shrink to roughly 20 percent from about 26 percent of the large-company stock index.
The new GICS structure changes represent a convergence toward the longstanding structure of the Syntax BRT, which groups companies engaged in the production, distribution, and processing of information into a top-level sector called “Information.”
S&P 500 Sector Changes Affect Your Portfolio and 401(k)
A major reshuffling of how stocks are labeled and categorized on Wall Street is taking place, which could prompt some investors to adjust their portfolios.
The big change is the creation of a new sector, dubbed Communication Services, which replaces the Telecommunication Services sector. This new sector will add a number of well-known tech and media stocks from the Information Technology and Consumer Discretionary sectors.
Just because some stocks in the S&P 500's 11 sectors have been shuffled, it won't impact the price movements of the capitalization-weighted S&P 500.
The weighting of tech stocks will shrink to roughly 20 percent from about 26 percent of the large-company stock index.
Popular and strong-performing names such as Facebook and Google parent Alphabet will be moving to the new Communications Services grouping.
Investors who use sector funds to gain exposure to these stocks will need to buy a fund or exchange-traded fund that tracks the new sector, which will have a 10 percent weighting in the S&P 500.
The new Communication Services sector will be less defensive and offer a much smaller dividend yield than the old telecom sector, which offered a yield of more than 5 percent.
Two stocks – Facebook and Alphabet – will account for 45 percent of the new index, while Amazon will now make up 32 percent of the Consumer Discretionary sector.
The top 10 holdings in the new Communication Services Select Sector Index will include three of the four FANG stocks – Facebook, Netflix, and Google parent Alphabet – as well as The Walt Disney Company.
The Communication Services Select Sector Index returned a cumulative 143.5 percent through May 16, 2018, with annualized performance of 14.2 percent over three years, 12.7 percent over five years, and 9.9 percent over ten years.
Over 89 percent of the components are currently classified as discretionary or tech stocks, while the remaining 10.8 percent are traditional telecom names.
