Trading around Thanksgiving has a bullish tendency perhaps buoyed by the “holiday spirit.” First published in the 1987 Stock Trader’s Almanac, the Wednesday before and the Friday after Thanksgiving combined were up 34 times in 35 years. The only S&P 500 decline was in 1964. 

 

Subsequently, this trend changed. In the 30 years since 1987, there have been 8 declines and 22 advances. The best short-term trade appears to be getting long into weakness on Monday or Tuesday of Thanksgiving week and selling into any subsequent rally by the end of Thanksgiving week, but remain nimble as events like Greece’s debt crisis in 2011 can cancel Thanksgiving on Wall Street.

 

 

Also of note is the change in the yearend rally. Prior to 1987, from the close of trading on the Friday after Thanksgiving to yearend, the S&P 500 rallied only 20 times in 35 years. As Thanksgiving bullishness lost steam in 1987, the rally afterwards occurred more frequently. Since 1987, S&P 500 has logged gains in 22 of 30 years from the close on Friday after Thanksgiving to yearend.
