Brett Arends cites several factors for his skepticism about the 4th quarter 2010 US stock market rally. Cyclically adjusted price to earnings ratios that are 75% above their average value. A market value for US equities excluding financial stocks, that is within 15% of the October 2007 peak. Fed data that shows nonfinancial corporations have debt of $7.4 trillion at the end of the third quarter 2010, an increase of $250 billion in one year, and up from $5.5 trillion in 2005.
