Since the 1980's, the number of American households that owns equities has almost tripled. Today, nearly 57 million, half of all U.S. households, own stocks directly or through mutual funds. This is according to the third joint study on "Equity Ownership in America," by the Investment Company Institute of Washington and the Securities Industry Association of New York.
The study was conducted by the Boston Research Group this past January, under the direction of both the ICI and the SIA. The research was done via telephone interviews with 2,414 equity investors.
