Tensions between the United States and Iran increased over the weekend, and all three main averages finished Monday lower. The Dow Jones Industrial Average fell 4.87 points, or 0.01%, while the S&P 500 fell 0.24%. The Nasdaq Composite ended its longest winning run since 1992 with a 0.26% decline.

Ohsung Kwon stated on Monday afternoon, “We have our upside target of 7,300 by July, which is basically our year-end target. I believe that for the next three months, the economy will be fine.” Kwon’s S&P 500 price prediction of 7,300 would indicate a 3% increase from the index’s Monday close.

Investors will keep an eye on Kevin Warsh, the nominee for chair of the Federal Reserve, during his confirmation hearing on Tuesday. The former Fed governor stated that the U.S. central bank must remain mostly independent of political interference while maintaining emphasis on its main objectives in his prepared speech to the Senate Banking committee, which was made public on Monday. He declared, “The Fed must stay in its lane. When the Fed strays into fiscal and social policies where it lacks authority and expertise, its independence is most at risk.”
