In December 2014, the Nasdaq forecast an increase in market volatility and a strengthening U.S. economy in 2015, according to Nasdaq. Analysts use the Nasdaq Composite Index to make predictions about the immediate future that are based on the performance of indexed stocks in the preceding year.
In July 2015, Nasdaq analysts predicted instability in global stock markets resulting from the Greek financial crisis, making international investments risky for the remainder of 2015. In U.S. markets, sectors such as health care, real estate, and technology that saw first-half gains will continue to rise. Low interest rates will continue to fuel the increase in mergers and acquisitions seen in the first half of 2015, spurring gains in the overall market, Nasdaq reports.
