One of the most common investor portfolios we see utilizes an allocation that funds 60% of investible assets into stocks and 40% into bonds. These so-called "60/40" portfolios are typically rebalanced at the end of each year to reestablish their target ratios. Although they are used by individual and institutional investors alike, the advent of exchange traded funds has made it especially easy for individuals to further diversify both sides of the equation to also include global stocks and bonds, real estate, and commodities.
