Major U.S. stock-indexes little changed on Tuesday after Federal Reserve Chair Janet Yellen said the central bank would be cautious in raising interest rates given risks such as Britain's membership in the European Union and a slowdown in the U.S. labor market. The central bank left interest rates unchanged and cut the economy's growth forecast last week after surprisingly weak monthly hiring data put the economy's recovery in question. Britain's vote on its EU membership on Thursday has left investors nervous over its repercussions on the U.S. markets.
