Goldman Sachs, Visa and Nike will join the Dow Jones Industrial Average, replacing Alcoa, Bank of America and Hewlett-Packard. The changes will be effective with the opening of trading on Sept. 23, S&P Dow Jones Indices said in a statement.

Obama is scheduled to address the U.S. public on Syria on Tuesday evening. (CNBC.com will stream this event live.)
