Amazon and other big technology companies rise sharply in early trading; broader market mixed

Big gains by Amazon and Google are lifting technology stocks in early trading.

Amazon soared 15 percent early Friday after revealing details about its cloud computing service for the first time. Google and Microsoft also rose after reporting their latest quarterly results.

The technology-heavy Nasdaq composite index rose far more than the rest of the market. The Nasdaq gained 32 points, or 0.7 percent, to 5,087 as of 9:35 a.m. Eastern time.

The gain came a day after the index beat its record-high close from 2000 at the height of the dot-com boom.

The Dow Jones industrial average fell 21 points, or 0.1 percent, to 18,036.

The Standard & Poor's 500 rose two points, or 0.1 percent, to 2,115.
