Facebook, Apple, Microsoft, Google, and Amazon account for more than 15% of market capitalization of the U.S. stock market.

FAMGA stands for Facebook, Apple, Microsoft, Google, and Amazon. These tech giants account for more than 15% of market capitalization of the American stock market (NYSE, NASDAQ, and AMEX). Facebook's recent acquisitions of WhatsApp, Instagram, and Oculus have expanded the social media network to encapsulate more than 2 billion active users worldwide. At present, Google still beats Facebook in terms of average revenue per user (ARPU) (about $45 vis-à-vis $20) and dominates the global Internet search and advertisement market.

Microsoft heralds its latest Windows 10 operating system updates and Office 365 suites for better user experience and word-of-mouth proliferation. Moreover, Amazon introduces Retail 2.0 or the Internet of Everything (IoE) in lieu of typical e-commerce with its recent acquisition of Whole Foods to better compete with Wal-Mart, Best Buy, Macy's, Neiman Marcus, JC Penny, and so on.

Apple brings about its iPhone X with AMOLED curvy touch screen and wireless charging functions to celebrate the 10^th anniversary of its revolutionary smart phone launch. Many upstream international iPhone suppliers experience hefty stock market gains in recent times. We expect FAMGA to continue to dominate in social media, IoE, software, Internet search and advertisement, and mobile technology with their *competitive moats* from rare and inimitable patents and new proprietary technologies to increasingly inclusive and powerful platforms, networks, and algorithms.
