S&P 500 Eight-Day Winning Streaks

With a positive start to the trading day, the S&P 500 is currently on pace for its eighth straight day of gains.  If the index closes in the green, it will be the first eight-day winning streak since November 2004, and the 36th streak of eight or more days over the last 50 years.  The table below lists each S&P 500 streak of eight or more days since 1963.  For each period we list the date of the eighth straight up day, as well as the performance for the S&P 500 on the ninth trading day.  Finally, we also show how many trading days the streak lasted.

Looking at the table below, the average return of the S&P 500 the day after eight straight days of gains is a decline of 0.13%.  While the average return is negative, the index has actually been positive on day nine (20 times) more often than it has been down (15 times).  So more often than not, the S&P has been positive on day nine than it has been negative.  Overall, the longest winning streak for the S&P 500 over the last fifty years has been 14 trading days in April 1971.
