By Yashaswini Swamynathan U.S. stocks struggled for direction on Tuesday as investors chose to look beyond President Donald Trump's first major policy setback, while awaiting comments from several Federal Reserve officials, including Fed Chair Janet Yellen. A failed healthcare bill sent the dollar and stocks down on Monday as investors questioned Trump's ability to push his ambitious agenda of tax cuts and simpler regulations in Congress. However, markets steadied after Trump said he would turn his attention to "big tax cuts". The White House later said it would lead the role in reforming the U.S. tax code, eyeing an August deadline. "Yesterday's move was actually quite a small unwind and was quickly opposed, and it tells me that investor sentiment hasn't been unduly damaged by the failure of that (healthcare) legislation," said James Athey, Investment Manager at Aberdeen Asset Management. "We would see this volatility to be normal and healthy and not something to be overly concerned about at this stage." Investors are awaiting Federal Reserve Chair Janet Yellen's speech at a conference in Washington, where she could provide some insight into the timing of the central bank's next interest rate hike. Other Fed officials scheduled to speak at separate events include Fed Board Governor Jerome Powell, Dallas Fed President Robert Kaplan and his Kansas City counterpart, Esther George.
