St. Louis Federal Reserve Financial Stress Index
July 29, 2010  updated weekly 

The St. Louis Fed's Financial Stress Index (STLFSI) is a recently created tool to measure financial stability. It is based on 18 indicators, as explained in this PDF release from earlier this year.

The latest reading, through Friday July 23, is 1.5% lower than the previous week.

Let's take a look at the index with an overlay of the S&P 500. The purpose is to get a sense of how the index correlates to market behavior.

The shorter timeframe makes it clearer that the Stress Index began rising before the market peak in 2007, and the Stress Index peaked before the market low of 2009. However, the relationship over the longer timeframe doesn't show a consistent pattern of financial stress leading the market.
