There hasn't been clear direction regarding the potential for United States' involvement in any of the global crises, with the exception of ISIS. The uncertainty surrounding the potential for US action coupled with the uncertainty of actions by foreign actors, such as Russia, creates a volatile environment for investors. Russia could impose stronger restrictions affecting the European markets minimizing U.S. potential to invest.
With the economy the way it is and the president in office yes I say be cautious. I think when it comes to your future with your money you need to protect it. Right now with the economy and the things going on in the world I would be afraid to invse in any stocks
