Wednesday was a generally good day for investors on Wall Street, featuring a gentle rise of about 0.15% to 0.25% for major benchmarks like the Dow and the S&P 500. The White House continued to make its case for the tax reform proposal it has put before lawmakers, and the release of the latest minutes from the Federal Reserve's meeting last month also hinted that the central bank wants to be careful not to tighten monetary policy too quickly.
