The DJIA is cautiously lower ahead of this afternoon's Fed announcement
The Dow Jones Industrial Average (DJIA) is trading lower at midday -- while the S&P 500 Index (SPX) and Nasdaq Composite (COMP) are on track to extend their daily losing streak to seven -- ahead of this afternoon's Federal Open Market Committee (FOMC) policy announcement. Although no changes are expected, traders will be keeping an ear to the ground for clues on an expected December interest rate hike. Stocks are also reacting to growing uncertainty surrounding the U.S. presidential election, with some polls showing a tight race between Hillary Clinton and Donald Trump. A sharp drop in oil prices is also weighing on stocks, after the Energy Information Administration (EIA) reported the largest one-week increase in domestic crude inventories on record. As such, December-dated crude futures are trading 3.1% lower at $45.23 per barrel.
