Molson Coors and Akamai Technologies both rose sharply early Wednesday after reporting results that easily beat analysts’ estimates. Lyft fell after reporting that its annual loss more than doubled last year. The S&P 500 index rose 19 points, or 0.6%, to 3,377. The Dow Jones Industrial Average climbed 227 points, or 0.8%, to 29,510. The Nasdaq composite rose 66 points, or 0.7%, to 9,706. Bond prices fell. The yield on the 10-year Treasury note rose to 1.63%.
