This fund puts at least 90% of its money into the stocks that make up its benchmark index, which tracks the 100 largest non-financial companies listed on the Nasdaq stock exchange, spanning both U.S. and international businesses. The index is built and maintained by Nasdaq Inc. using set rules and procedures, with companies selected based on their overall market size. Because the fund concentrates its holdings in a relatively small number of companies, it carries more risk than a broadly diversified fund.
