Doug Short has been charting the stock market using the S&P 500 stock index since it peaked at 1565.15 on October 9, 2007.
Here is his Current Market Snapshot.
Bottom line, but not counting dividends, after 46 months, and including the 2008-2009 bloodletting, the index is down 25.1% (and that’s after today’s 4.6% bounce).
Which is probably better than your house has done.
