Since the US election in November, the 5 biggest stocks on the NASDAQ: Amazon, Apple, Facebook, Google and Microsoft have gained an extraordinary $675 billion in market capitalization.
This move higher pushes their collective valuations to close to $3 trillion, or over 10% of the entire US market.
To put this into a global context, that’s more than the total value of stocks in any single equity market worldwide except the UK, China, Japan, Hong Kong and the USA.
