Barron's 400 Index


The Barron’s 400 Index, or B400, was jointly developed by Barron’s and MarketGrader and introduced on the cover of the September 3, 2007 issue of Barron’s magazine. In Barron’s words, the index “collects the most fundamentally sound and attractively priced stocks from all corners of the market, using a proven and disciplined stock-selection process.” B400 does not strive to be a benchmark representing the overall U.S. equity market but rather a tool designed to give investors access to America’s most promising stocks.
