The stock market tends to have unusually strong performance during the final five trading days of the year and the first two tradings days of the new year, which Wall Street nicknamed "the Santa Claus rally." The S&P 500 has posted a 1.3% gain on average since 1950 during those periods, according to the Stock Trader's Almanac, which helped define the period.

It has worked for the most part in the last 10 years. The S&P 500 has only had two declines, in 2014 and 2015, during those seven trading days in the past decade, according to Stock Trader's Almanac.
