On Monday, U.S. equities showed mixed performance while Brent crude fell sharply after the United States and Iran paused their hostilities.

The Dow Jones Industrial Average rose 218 points (0.4%) in the AP report and 88 points (0.2%) in the Boston Herald. The Nasdaq composite declined 0.6% and 0.4%.

Federal Reserve Outlook
The Federal Reserve is slated to provide an update on its interest-rate policy on Wednesday. Market participants estimate roughly a 36% probability that the Fed will raise rates at that meeting, a move intended to temper inflation that has been aggravated by higher fuel costs and the ongoing U.S.–Iran conflict. Analysts note that the central bank has kept rates steady throughout the year but expects at least one hike before year-end.
