Deepest Prices Drop since April 20


May 13, 2009


The NASDAQ loss of  -3.01 percent, its worst performance in the last 17 trading days, is also its third straight decline.  The last time this index fell three days in a row was on February 27. 

The S&P500, down  -2.69 percent, and the DJIA, off -2.18 percent, also posted their deepest loss since April 20.  Indeed, only 49 declines steeper than today’s occurred since January 2000; moreover, only 20 such closes exist before 2000.

Only the DJIA continued its up-and-down gyration, now in its seventh day, while the other two indices experienced their third decline in as many days.  This is the 21st repeat of this pattern since 1975; yet it has not been seen since October 2005.

In the past, the day following posted declines more often than gains.  The NASDAQ fell 14 times and moved higher on six days.  The DJIA has an 11 negative and 9 positive history, while the S&P500 scored 8 advances against 12 declines.

This heavily downward bias is similar to yesterday’s state of affairs, in which the frequency of losses in the past outnumbered gains on the next day.  In that sense, history provided a useful guide to today’s outcome.

 

DJIA                  -2.18 percent

NASDAQ          -3.01 percent

S&P500             -2.69 percent
