S&P on Pace for Fewest Down Days in a Month Since at Least October 2006

Assuming a gain today, the S&P will guarantee itself of having the fewest down days in a given month since at least October 2006, when the index closed down on 5 trading sessions. So far in December, the S&P has fallen on just three days, with all fractional declines.

How rare of an occurrence is that?

Since 1950 for the S&P 500:

0-1 days of declines in a month


2 days of declines in a month

Once – November 1968

3 days of declines in a month

4 times – September 1954, June 1955, January 1965, July 1989

4 days of declines in a month

7 times – January 1954, January 1961, January 1967, July 1967, September 1968, November 1980, May 1990

5 days of declines in a month

26 times – last being in October 2006; has only happened 9 times since 1973

And the statistic could become even more impressive if the S&P finishes up another 1-2 more times after today too.

Additionally, the lack of volatility has been noticeable. The VIX is hovering near 8-month lows too, but notice the Dow has had a percent change (up or down) of more than 1% on just one trading day this month. That has happened just one other time over the last 3.5 years (March 2010).
