Chicago Fed National Activity
The Chicago Fed National Activity Index, which looks at 85 monthly economic indicators to get a sense of how well the economy is doing right now, is extremely low:
There have only been 3 other historical months with such low readings. This occurred in December 1974 after the massive 1973-1974 bear market ended. This also occurred in December 2008 - January 2009, when stocks fell more over the next 2 months before hitting a bear market bottom.
While this may be deemed a bullish long term factor for stocks under normal circumstances, I wouldn't put too much weight on this. The current recession is so different from historical ones that I would underweight all economic data right now.
