Range, from James Sogi
Recent moves looked a bit like the year 2000 when there were bigger moves up and down. Looking at the average weekly average of the daily range of S&P futures as a measure, and using the median as a robust way to count varying periods, it looks like that measure of volatility is rising recently.
Days Median average weekly range
200 10
100 11
20 12
10 15
During 2000, the median S&P median weekly range exceeded 15 also. This size of larger range was more common in 2000 and during the two years after.
