Wall Street retreats amid rising concerns on government shutdown

U.S. stocks decreased on Wednesday falling for the second straight day amid lingering concerns that the first partial shutdown of the U.S. government in 17 years may be prolonged and as a report showed smaller-than-expected number of jobs added by employers last month. The Nasdaq Composite Index declined 2.96 points to 3,815.02, while the Dow Jones industrial average and S&P 500 Index fell as well.
