FYI: Like just about every other year, volatility in the market picked up as traders and investors came back from the beach in September. With a decline of over 1% yesterday, the net advance/decline (A/D) reading on the S&P 500 registered -457, marking the sixth all-or-nothing day for the S&P 500 since Labor Day. For those not familiar with the term, we consider an all-or-nothing day to be any trading day where the net A/D reading for the S&P 500 is greater than +400 or less than -400. With today’s move, the S&P 500 has seen its 26th all-or-nothing day of the year, which puts the index on pace for 33 this year. At this rate, 2016 will come up short of the 38 occurrences in 2015 but still would rank as the sixth most number of occurrences for a given year since 1990.
