Caliber

NYSE Update For The Week Of September 26th 2016

The Caliber of the NYSE fell last week from 554 to 531 which means there is less diversity in the NYSE and consequently more volatility and risk. The number 531 means that over the last 60 trading days the NYSE behaved as if it was made up of 531 completely independent stocks, after individual stock trends were removed. The current Caliber is greater than 47% of all Calibers over the last 25 years. Higher Calibers sometimes coincided with better market conditions in the past but this might not be the case in the future.

The Caliber calculated for each 60 day period over the past year.
