S&P 500 tops $20 trillion as Wall Street trades on Trump

The S&P 500 has surged about 9 percent since Trump's Nov. 8 election, boosted by expectations he would lower corporate taxes, ease regulations governing banks and increase infrastructure spending. The S&P 500 financials index jumped 1.1 percent, with Citigroup up 2.3 percent. The two sectors are seen benefiting heavily from Trump's policies.
