NEW YORK Apple is the first U.S. company to boast a market value of $2 trillion, just two years after it became the first to reach $1 trillion. Apple has been at the vanguard of a group of Big Tech companies that are increasingly taking over peoples lives -- and the stock market. Just five companies -- Apple, Microsoft, Amazon, Facebook and Googles parent company -- account for nearly 23% of the S&P 500s entire value. Saudi Aramco reached a market value of $2 trillion shortly after becoming a public company in December 2019. The Saudi energy producers shares have fallen since amid a drop in oil prices and its market value is now about $1.82 trillion.
