Investment Review - December 2017

  1. In November, particularly in the final trading days of the month, investors bid stocks higher on hopes that tax reform legislation would be passed in Washington. On a total-return basis including dividends, the S&P 500 benchmark index rose 2.2% over the course of November, extending its string of monthly advances to a record 13. Over the entire 13-month period, the benchmark index rose 26.3% on a total-return basis. The previous streak, according to Dow Jones data, was a 10-month rally that ended in September 1995. The Dow Jones Industrial Average rose 3.8% in November, closing out its eighth straight positive month, its longest such streak since 1995, according to FactSet. The Nasdaq Composite notched an impressive +2.5% month.

  2. If history is any indication, the S&P’s record-setting streak could continue, as December is typically a strong month. According to the Stock Trader’s Almanac, December is historically the strongest month of the year, with an average gain of 1.6%, based on data going back to 1950.
