Wall Street stocks bounced back from the prior session's rout as tech shares gained. Analysts hope the upcoming earnings period will shake the market out of its current anxiety over trade policy and technology industry problems.

The broad-based S&P 500 gained 1.3 percent. Dow was up 1.7 percent and Nasdaq was up 1 percent. Technology companies led the advance, with Tesla Motors surging 6 percent after reporting that it reached weekly production of about 2 thousand Model 3 sedans at the end of the first quarter.

Amazon, Facebook, Alphabet and Intel all pushed higher. Europe's stock markets, in their first session since the Easter holiday break, slid Tuesday on trade war fears. European markets took their cues from Monday's US session, when major indices fell sharply on worries about trade and technology sector problems. But traders said the partial rebound in American stocks helped lift European bourses off their worst levels.
