Stocks jumped in early trading on Monday, with the Dow Jones Industrial Average opening 400 points higher and the S&P 500 and Nasdaq Composite each rising over 1%.

Why it matters: The stock surge comes after the 90-day ceasefire of the trade war between the U.S. and China, with the hope that it will ratchet down tensions between the two nations in the long term and provide relief for companies that have been feeling the pain from tariffs.
