The S&P 500 is trading significantly higher after the Democratic party secured majorities in both the House and Senate in the U.S. midterm elections. Investors are reacting positively to the prospect of a divided government, which is perceived as reducing the likelihood of major policy shifts and creating a more predictable environment for businesses. A conciliatory tone from President Trump has also contributed to the relief rally. The advance is broad-based, with large-cap technology and semiconductor stocks among the leading gainers.
