The U.S. stock market has experienced a tough December.
With stocks plunging earlier this month in one of the biggest losses since the 1929 market crash, some investors are worried earnings growth may have peaked and the economy could slow in 2019. The stock market's roller-coaster like changes in December, which have included record drops and gains, has led to dramatic stock sell-offs that some analysts say could indicate the country's 15-month bull market could be coming to a close.
