Wall Street hits records again, boosted by Trump economy hopes

The S&P 500 tallied its fourth straight session of gains, a day after Trump vowed a major tax announcement in the next few weeks. The benchmark S&P 500 has surged 8.3 percent since Trump's Nov. 8 election, fueled by expectations he will lower corporate taxes, reduce regulations and increase infrastructure spending. The rally had stalled amid concerns over Trump's protectionist stance and lack of clarity on policy reforms.
