July 13, 2010 Streak Extends to Six in a Row

                                  CORRECTION 

 YESTERDAY’S BLOG SHOULD READ “…for five straight days…” 

Today’s large advances stretched the sequence to six successive gains for the DJIA, the NASDAQ and the SP500. While rare, the last occurrence was just weeks ago, on April 15.  Furthermore, only one other close, also recent in December of last year, made it this far since January 2000. The other 11 repeats go back to the 20th century, to the beginning of our data base in 1950.

The record reveals that expectations of a seventh straight daily advance by all three indices will not be realized: only four sessions achieved that goal, with non since the last occasion in 1990.

Yet the likelihood of a further advance by one or two of these three indices is larger. The NASDAQ has registered seven straight gains 18 times, and the DJIA achieved this goal 9 times, but the S&P500 reached it only twice. 

DJIA               1.44 percent      NASDAQ     1.99  percent     S&P500          1.54  percent
