State and local pension plans' equity holdings and returns

This article explores recent trends in the size and performance of the equity investments of state and local pension plans. It also provides a context for the discussion about investing Social Security trust fund reserves in private equities. Equity holdings and returns for five of the largest private pension plans were compared with those of state and local pension plans. Key findings discussed in the article include: Equities were the largest investment in the aggregate portfolio of state and local pension plans in 1999 and represented 67 percent of the $3 trillion in aggregate state and local pension assets. Equity allocation of the five private plans resembled that of the aggregate. About 80 percent of state and local pension plan holdings were domestic equities in 1999. The five largest plans had about the same domestic/foreign allocation of equity investments during that same period. In 1999, state and local pension plans held about 11 percent of the U.S. equity market, which includes foreign equities held in the United States. State and local pension plans held about 10 percent of domestic equities in the U.S. equities market that same year. Returns on equity investments over a 10-year period were more than 17 percent for both private pensions and state and local pension plans. Although private plans tend to have slightly higher total returns, the difference stems from the higher equity asset allocation of the private pensions that were studied.
