The disrupters could get disrupted

FOUR mega-cap tech companies are so powerful and high-performing that Wall Street has a collective name for them - the FANG stocks, namely Facebook, Amazon, Netflix and Google.

These four firms alone have turbo-charged US stock market returns in recent years, reaching more than US$1.7 trillion in total market capitalisation.

Just as the growth, earnings and cash generation of these Big-Tech names have soared, so have their impact on economies and consumers, who are wowed by the services, price transparency and convenience they provide.
