There is still more than a week left to go in June, but after today's decline the S&P 500 has already seen its fourth all-or-nothing day of the month. 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. After a slow start to the year, the pace of all-or-nothing days has really picked up as nine of the year's sixteen occurrences have all come since the beginning of May. At the current rate, the S&P 500 is on pace to see 34 all-or-nothing days this year. This would rank as the fifth most all-or-nothing days in a year since 1990, but even if there is not another occurrence this year, 2012 would still rank seventh for the most all-or-nothing days since 1990. Guess we'll have to wait another year for one of those proverbial sleepy Summers.
