Major U.S. stock-indexes lower on Monday amid losses across sectors as investors' appetite for risk was curbed by geopolitical tensions in Asia and President Donald Trump's accusation that his predecessor, Barack Obama, wiretapped him. Some investors worried that the accusation could distract Trump from his economic agenda of introducing tax cuts and simplifying regulations, which have powered a record-setting rally on Wall Street since the election. However, the lack of detail on Trump's proposals and setbacks in filling his Cabinet have made investors jittery amid lofty market valuations.
