The Dow ended Thursday slightly lower, dragged down by a poorly performing Boeing (BA).
Boeing’s stock closed 2.9% lower, making it the worst performer in the Dow. The plane manufacturer has been struggling with the crisis surrounding its top-selling 737 Max airplane.
The aircraft, which was involved in two recent deadly crashes and has since been grounded around the world, received an updated computer system. But a new flaw has been discovered while the new system was tested in simulator flights, CNN reported earlier Thursday.
Gains in Walgreens Boots Alliance (WBA) stock help offset the Boeing losses.
The Dow (INDU) flipped between the positive and negative territory all day. It closed little changed but in the red, down 10 points.
Elsewhere, stocks trended higher across the board ahead of the G20 summit in Japan.
The S&P 500 (SPX) and the Nasdaq Composite (COMP) closed in the green, up 0.4% and 0.7%, respectively. Friday is the last trading day of the month, the quarter and the first half of the year. Stocks are on pace to record their best month since January.
