* Democrats win U.S. House, Republicans keep Senate

* Tech, health stocks gain though regulation fears loom

* Bank stocks flat as Treasury yields slip

Democrats won control of the House of Representatives on Tuesday, while President Donald Trump's Republican party expanded its Senate majority, pointing to the likelihood of political gridlock in Washington.
