U.S. stocks ended little changed on Thursday as the recent rally continued to stall following President Donald Trump's latest comments on trade and the policies he will pursue. The S&P 500 traded at levels it was six weeks ago, losing steam as investors focus on Trump's priorities, such as restricting travel to the United States and rewriting trade deals. Markets had run up sharply following Trump's Nov. 8 election win on the expectation that tax cuts, deregulation and a fiscal stimulus would accelerate economic growth.
