New York - Shares of internet search and advertising titan Google soared more than 13% to pass the $1 000 mark for the first time on Friday after a strong earnings report.
The earnings demonstrated that Google was smoothly building its presence in the mobile area while advertising earnings rose all around, with particular help from Google's YouTube website.
Ad volume growth accelerated to 26% year-on-year, Morgan Stanley pointed out, showing that Google was well on top of the evolution of the market beyond personal computers to smartphones and tablets.
"Rather than struggling with a mobile transition, Google is benefitting from increased screen fragmentation," the broker said.
Google reported its earnings after trade closed on Thursday.
The shares soared beyond the $1 000 barrier in early trade on Friday, topping $1 015 before settling at the close at $1 011.41, up 13.8% for the day.
The surge helped push the S&P 500 well beyond Thursday's all-time closing high to a fresh record of 1 744.50 points, up 0.7% for the day.
Google's success helped pull shares of other tech firms up as well, with social networking leader Facebook rising 3.8%, online retail power Amazon up 5.8%, and Yahoo 2.0%.
Together they helped drive the Nasdaq Composite index to a 1.3% gain to 3 914.28 points, its highest level since September 2000.
Google reported on Thursday a 36% jump in its third-quarter net profit to $2.97bn, or $8.75 a share. Revenues also beat forecasts with a 12% jump year-on-year.
Analysts said it was doing well in all areas of business, and had proven its ability to build business on its Android smartphone platform.
"We are closing in on our goal of a beautiful, simple, and intuitive experience regardless of your device," Google chief Larry Page told analysts.
Pivotal Research Group warned of eventual erosion of the company's still-healthy margins, but added: "Longer term, we remain optimistic about Google's continued success as the leading seller of display-based media and ad tech, and as the dominant provider of paid search advertising."
At the $1 011 mark, Google shares were up 43% from the beginning of the year, and the company's market value reached $337bn, still shy of leader Apple's $462bn.
Google was the second company on the S&P 500 list to top $1 000. Online travel firm Priceline was the first past the post in September, soaring to $1 074; it closed at $1 048 on Friday.
