With the S&P 500 now on pace for its fourth 'all or nothing day' since last Tuesday, 2011 has now tied and broken the record from 2008 for the most all or nothing days in a single year. We consider all or nothing days in the market to be days where the net daily A/D reading in the S&P 500 exceeds plus or minus 400. With today's current net A/D reading of -460, there have now been 55 all or nothing days for the S&P 500 in 2011. At this rate, 2011 is now on pace to see 66 all or nothing days, which is well above the prior high of 52 back in 2008.
In the 66 trading days since the start of August, more than half (35) have now been all or nothing days. As we noted last week, the number of occurrences that we have seen in the last three months eclipses the total number of all or nothing days that we saw from 1990 through 2001 (34).
