"The Big Five", which brought the growth of the US market in 2017 (1)

US indices performed well for the first four months, accounting for several percent of their record highs.
And while investors and analysts are arguing about this - expensive or inexpensive is the market, and where is the next bigger move, here are the five companies, who became the "pillars" of the rise.
And these companies are mostly from the technology sector. Companies such as Apple, Alphabet, Microsoft, Amazon and Facebook, except for the rise in the broad US S&P 500, also contributed to the record highs of technological Nasdaq on Thursday of last week.
The five companies made up between 12% and 13% of the capitalization of the 500 largest US companies.
