 "Top 3 US firms have nearly a fifth of mcap")
With chipmaker Nvidia becoming the world’s most valuable company, the top-three listed firms in the US now account for almost a fifth of its market capitalisation (mcap).
While no other country even has a single firm with a market value of $2 trillion, the US boasts of three companies in the three-trillion-dollar club.
The three US-listed tech giants — Nvidia, Microsoft and Apple — have a total mcap of a staggering $10 trillion. They account for 17 per cent of America's mcap of $57 trillion and over 8 per cent of the global figure of $118 trillion.
