Independence day and other Holidays Deliver Higher Return

 

  • this post is the sequel to the previous post;
  • there I grouped S&P 500's daily performance by dates from previous trading day;
  • and found '2days' group had higher return.
  • below is the risk and return plot of 4 group (1day to 4 days).
  • as mentioned, '2days' group has higher return than other groups


  • then distribution of return of '2days' group is shown below chart.
  • added '1day' group for the comparison.


  • difference of average performance came from performance around zero percent.
  • 2Days group has more dates with performance between '0% to 1%' than 1day group.
  • 1Day group has more dates with performance between '-1% to 0%' than 2days group.
  • these differences apparently led to 2Days group's higher performance.
