Between 1970 and 2015, the average yearly growth in the total market cap of Dow 30 index has been 9.9%. The decade with the fastest growth was 1990s but this include the excessive valuations before the dot-com boom. Between 2000 and 2009, the growth was negative 0.1%, mainly because of the financial crisis of 2000. The financial crisis decreased the value of the Dow Jones companies temporarily almost by half.

The values of the companies have steadily growing since 2008 but the growth began to halt during 2015 and 2016 started with large turbulence in stock markets around the world so the long bull market might be over.
