Since 2007 I have been posting charts showing annual stock market and bond market returns for various indices for the time periods from 1980-2006, 1980-2007, 1980-2008, and 1980-2009. These charts show returns for small cap indices (Russell 2000, Russell 2000 Value, and Russell 2000 Growth), large cap indices (S&P 500, S&P/Citi 500 Value, and S&P/Citi 500 Growth), a broad-based foreign stock index(Morgan Stanley Capital International Index for the developed stock markets of Europe, Australasia, and the Far East ("MSCI EAFE index")), an index of bonds (Barclays Capital Aggregate Bond Index Lehman Brothers Aggregate Bond Index ("BC Agg."))*, and the Nasdaq Composite Index. These charts have been updated as shown below (click on the image for a larger view) to reflect returns for 2010.
2010 was a good year across the board for most of the major stock indices as equities and bonds extended their rebound from the 2008 market collapse. Foreign stocks were hit hard at the beginning of 2010 as fears of a collapse of the Euro-zone after Greece experienced severe economic distress. Foreign markets eventually started to recover in May 2010 when the Eurozone agreed to bail out Greece. Equities also rallied strongly between September and December 2010 as the Federal Reserve ("FED") began implementing a program of quantitative easing known popularly as "QE2" pursuant to which the FED began purchasing up to $600 billion in bonds.
Small Caps provided the strongest returns during 2010, as shown below. The Russell 2000 Growth Index rose 29.09%, the Russell 2000 Index rose 26.86%, and the Russell 2000 Value Index rose 24.50%. Large caps also performed well, the S&P 500 Growth, Value, and Composite indices each returning slightly over 15%. Tech stocks also performed well, as evidenced by the return of 16.91% of the Nasdaq Composite Index. Foreign stocks lagged, with the MSCI EAFE Index rising a mere 7.75%, as a consequence of the economic distress within the Eurozone. Bonds provided steady returns as they have for the past 30 years, with the BC Agg. Index rising 6.54%.
As shown in the chart below, the Russell 2000 Value Index has provided the strongest returns by far between 1980 and 2010, returning a total of 4,349.98%, or an average of 13.02% per year. The total returns of the Russell 2000 Value Index has returned more than 1,600% more relative to its initial value on December 31, 1979 than the next best index I tracked, the S&P 500 Index.
* The BC Agg. bong index was known as the Lehman Brothers Aggregate Bond Index prior to 2008.
