Tech and healthcare sectors tighten grip on world stock markets

Platform News: Tech Titans including Facebook, Google, Amazon and Apple

The technology and healthcare sectors have tightened their grip on global stock markets since the coronavirus shock knocked world shares from February’s record highs. 

While banks, airlines and oil majors have been dumped by investors and the value of their shares has plummeted, sectors including the likes of pharma giant Roche and the US tech heavyweights now account for 42.8% of world stocks – more than twice that of energy and financial shares.

Healthcare and technology stocks globally have been resilient to the ongoing virus shock, with investors pumping $4.9 billion into those sectors in the last week, according to Bank of America Research.

Facebook, Apple, Amazon, Alphabet and Microsoft weigh a whopping 8.7% of global equity markets.


Never before has the overall weight of the top five S&P 500 stocks been as high as now, with these five companies making up more than 20% of the index’s 500 constituents.


The Nasdaq, home to some of the biggest US tech names, is now worth about twice as much as all Asian shares excluding Japan.

Part of the explanation of why healthcare and tech stocks’ are ruling supreme over trading floors is their resilience during the COVID-19 crisis.
