- Cut down the number of different sources and upgraded their quality
- Made all 2005 and later returns tied to actual investments (except for the Hedge Fund index which is borderline meaningless due to relaxed reporting requirement, but I have decided to keep it anyway). I picked 2005 as the switchover point from synthetic to actual because it was the first year for which all data series had actual widely traded investments. Using actual investments will make it easy to keep updating the charting too in the future.
- Added small-caps data, with the caveat described in Small Cap Premium Or Liquidity Premium
- Added data for years 1926 and 1927 on the front and, of course, 2012 on the end.
- Added data series for 5-year treasury bonds.
- Kept data series for 10-year treasury bonds as synthetic composite of two parts 5-years and one part 20-years. I have been used this data series in my posts, but was not happy with the data quality. Now I have switched to different data sources, which cover 5-year and 20-year T-Bonds, so I kept the 10-year as a composite of those two so old links don't break. It should be a pretty good approximation, especially over long periods of time. But it will certainly be off by a percent or three any one year. The 5- and 20-year T-Bonds data should be much more reliable.
If you notice any problems with the data or the charting tool itself, please let me know by leaving a comment here. Unfortunately it does not work well in the Internet Explorer at all -- that's still on my to-do list but in the meanwhile, please use other web browsers for the charting tool.
