How many Mega Cap companies operate per sector?

Technology (12), Consumer Goods (12) and Healthcare (11) are the niches with the most companies, while the list is completed by Finance (4), Services (3) and Utilities (2).

“The recent rapid shifts in the way society operates and the related need for digitization of the world shifted the focus of investors to the fast-growing technology, fintech, and e-commerce markets. Clear evidence for that is the fact that over 30% of the market cap of all Mega Cap companies is made of 3 companies and all of them operate in the technology sector,” said BestBrokers market analyst Alan Goldberg.


A total of 12 Mega Cap companies operates in the technology sector which makes up 27.3% but their total market cap is over 44% (US$9,349.82 billion) out of the total US$21,187.25 billion.

Visa, Mastercard and Walt Disney are the only companies in the mega cap list which operate in the Services sector.

There is some speculation that Shell ($161.58 billion) will soon join them in this list.

“The past few months has seen the markets going sharply down and the mega market cap list shrinking. Now, with inflation dropping and marketing picking up, we can expect more companies to cross the $200 billion threshold valuation,” added Alan Goldberg.
