MARKETS: Internet company continues its surge and reaches yet another milestone. By Michael Liedtke THE ASSOCIATED PRESS Google Inc.’s stock price sailed past $600 for the first time Monday, extending a monthlong rally propelled by the lofty expectations surrounding the Internet search leader’s upcoming third-quarter earnings report. The biggest beneficiaries of the stock’s ascension have been Larry Page and Sergey Brin, who began developing their search engine, then called BackRub, in a Stanford University dorm room in 1996. Page and Brin, both 34, rank among the world’s wealthiest people, with fortunes approaching $20 billion each. Google’s CEO, Eric Schmidt, and top sales executive Omid Kordestani have also accumulated enough stock in the company to become multibillionaires. Hundreds of other Google employees are millionaires. Google’s stock has reigned as one of the hottest commodities on Wall Street because its search engine has turned into a moneymaking machine as advertisers spend more on the Internet to connect with consumers who are increasingly shunning television, radio and traditional print media. Google’s search engine is the hub of the Web’s most lucrative ad network. 160Want local news?Sign up for the Localist and stay informed Something went wrong.

It marked the sixth time in the past 12 trading sessions that the stock has reached a new high, showing investors are confident Google’s third-quarter profit will be impressive. The results are scheduled to be released Oct. 18. The latest milestone served as yet another reminder of the immense wealth created since Google went public in August 2004. The shares have increased more than sevenfold from their initial public offering price of $85, bringing the nine-year-old company’s market value to $190 billion – eclipsing bigger, more mature businesses such as Wal-Mart Stores Inc., Coca-Cola Co., Hewlett-Packard Co. and IBM Corp. It took 10 months for Google’s stock to leap from $500 to $600 and more than a year for the journey from $400 to $500. The shares hurdled $300 in June 2005 after passing the $100 and $200 thresholds in 2004. Analysts began predicting Google’s stock would reach $600 at the start of 2006 when the shares were still hovering around $420. Some analysts are already predicting Google’s stock will hit $700 within the next year, but the average target price for the stock is $614.64 among analysts polled by Thomson Financial.
