Past performance is no guarantee of future results. The returns of an index do not represent actual investor returns as one cannot invest directly in an index.
Sources: Vanguard calculations, based on data from Global Financial Data (GFD) as of December 31, 2023. The 60% GFD US-100 Index and 40% GFD US Bond Index is calculated by GFD. The GFD US-100 Index includes the top 25 companies from 1825 to 1850, the top 50 companies from 1850 to 1900, and the top 100 companies by capitalization from 1900 to the present. In January of each year, the largest companies in the United States are ranked by capitalization, and the largest companies are chosen to be part of the index for that year. The next year, a new list is created and chain-linked to the previous year’s index. The index is capitalization-weighted, and both price and return indexes are calculated. The GFD US Bond Index uses the U.S. government bond closest to a 10-year maturity without exceeding 10 years from 1786 until 1941 and the Federal Reserve’s 10-year constant maturity yield beginning in 1941. Each month, changes in the price of the underlying bond are calculated to determine any capital gain or loss. The index assumes a laddered portfolio that pays interest monthly.
