The S&P 500 and NASDAQ Composite opened higher on Monday as they got a boost from tech shares like Apple and Facebook.
The Dow Jones Industrial Average faded 16.31 points to begin Monday at 25,433.93, as shares of Boeing dragged down the 30-stock index.
The S&P 500 advanced 18.68 points to 2,761.75, as the tech sector climbed more than 1%.
The NASDAQ Composite climbed 79.15 points, or 1.1%, to 7,487.30.
Boeing fell more than 9% after a flight crash on Sunday that involved the 737 MAX 8 jet. This is the second crash in less than six months involving that model.
Boeing's decline shaved off more than 300 points from the Dow, given the index's price-weighted nature and the stock's high price relative to other Dow components. In other words, the Dow would be positive along with the S&P 500 and NASDAQ if not for Boeing's decline.
Apple shares rose more than 2.5% after Bank of America Merrill Lynch upgraded the stock to buy from neutral, noting the company's recent pullback presents "opportunity." The bank also raised its 12-month price target to $210 per share from $180.
Facebook also gained more than 2% after Nomura Instinet upgraded it to buy from neutral. In a note to clients, analyst Mark Kelley said consumers are transitioning to Facebook's Stories format and its increased focus on messaging. Kelley also hiked his price target to $215 per share from $172.
