After a shaky finish to 2018 that caused worry among investors, U.S. equities are on track to close out 2019 with strong performance.

The S&P 500 Index was up about 25% as of December 11, and with lower volatility than in 2018, investors were treated to a relatively stable, calm movement upward throughout the year.
