Stocks opened slightly higher Tuesday, with all three major indexes scoring new all-time highs as investors remained optimistic over prospects for a so-called phase one trade agreement between the U.S. and China.

The Dow Jones Industrial Average was up around 47 points, or 0.2%, at 28,083, while the S&P 500 advanced 3.37 points, or 0.1%, to 3,125.40. The Nasdaq Composite rose 25 points, or 0.3%, to 8,574. Shares of Boeing Co. rose 1.3% to lead Dow gainers after the embattled aircraft maker received 50 orders for its grounded 737 MAX plane.
