SAN FRANCISCO (Reuters) - An overhauled telecommunications sector featuring most of the so-called FANG stocks could debut as Wall Street’s hottest bet when it kicks off in September, boosted by a rising wave of media and television acquisitions.

Long viewed as stodgy stocks for dividend-oriented investors, the telecom services sector .SPLRCL will be renamed communications services and supercharged with the addition of Facebook FB.O, Netflix NFLX.O and Google-owner Alphabet GOOGL.O - three of the four FANGs, along with Amazon - as well as other companies that have driven the stock market to record highs in recent years.

The changes are part of the largest-ever shakeup of the stock market’s broad business categories.

In total, 14 S&P 500 companies, including Netflix, will shift from the consumer discretionary sector into communications, joining AT&T, Verizon Communications VZ.N and CenturyLink CTL.N in the biggest shakeup of the Global Industry Classification Standard, or GICS, since it was created in 1999. Five S&P 500 companies will switch from technology to communications.

The new sector will also include Walt Disney DIS.N, Comcast CMCSA.O and other entertainment and media companies scrambling to consolidate and fend off competition from newcomers Netflix and Alphabet, which produce content and sell it directly to consumers.

The floodgates for such deals were sprung open this month by a legal ruling giving AT&T T.N the go-ahead to buy Time Warner for $85 billion.

“Among all of the sector groups, this is going to be the most dynamic,” predicted Jack Ablin, chief investment officer at Cresset Wealth Advisors in Chicago. “You will see a lot of deal activity in the coming months, and it will be an awakening for anyone who is not on top of it.”

Amazon.com AMZN.O, the fourth FANG stock, will stay in consumer discretionary and represent nearly a third of that sector.

Classifying companies within 11 major sectors and several sub-sectors, GICS is closely followed by sector analysts and investors. Its overhaul, which has yet to be finalized, aims to reflect the evolution of the media, telecommunications and Internet industries.

Getting a head start on the September revamp, State Street Global Advisors on Tuesday launched here the Communication Services Select Sector SPDR Fund XLC, benchmarked to the sector's future configuration.

Reflecting Wall Street's willingness to pay top dollar for companies like Alphabet, Netflix and Activision Blizzard ATVI.O, the newly constituted communications sector would trade at 19 times expected earnings, nearly double the sector's current multiple, according to Thomson Reuters I/B/E/S.

Earnings of the newly constituted communications sector are expected to jump 23 percent in the final quarter of 2018, compared with an estimated 12 percent increase under the sector’s current configuration.

Over the past five years, the telecommunications sector has had a total return of just 16 percent, including dividends. Under its new configuration, it would have had a total return of 110 percent and outperformed the S&P 500’s 85 percent return, according to Credit Suisse equity strategist Patrick Palfrey.

Media, television and wireless companies, all of which will become part of the Communications sector, see buying content producers as a way to add revenue.

Twenty-First Century Fox FOXA.O has surged 20 percent since June 13, when Comcast offered $65 billion for its media assets, outbidding an offer from Walt Disney, which responded on Tuesday by raising its bid to $71 billion.

Sprint S.N, T-Mobile TMUS.O, Viacom VIAB.O, CBS CBS.N, Dish Network DISH.O and Discovery DISCA.O have risen between 6 percent and 34 percent in June.

Even if M&A speculation subsides before the GICS changes take effect, the addition of most of the FANGs and several other high-growth former tech stocks will make the communications sector attractive, said Michael James, managing director of equity trading at Wedbush Securities in Los Angeles.

“Interest in the sector and the individual names is not going to dissipate,” James said.
