Financial Analyst Lane Jones of Coral Gables Evensky and Katz said as we enter the third Quarter, the economy is still facing serious challenges, but, “The economy continues to grind forward, particularly the U.S. economy continues to grind forward. And relative to the rest of the world, we probably look a little bit better.”
