Why the discrepancy between the data on Bogleheads and from the Morningstar/Ibbotson Yearbook? For example, the treasury bills on Boglehead (which just comes from Aswath Damodaran):
http://www.bogleheads.org/wiki/Treasury ... al_returns
1928 3.08%
1929 3.16%
1930 4.55%
1931 2.31%
1932 1.07%
1933 0.96%
...
Versus the data from Morningstar:
1928 3.56
1929 4.75
1930 2.41
1931 1.07
1932 0.96
1933 0.30
What gives? Who is doing their arithmetic correctly? And who is not?
