Google Shares Surge Past $500

Google's stock set yet another milestone during trading Tuesday, surpassing the $500 mark for the first time ever. If the stock manages to close above that level, it would be one of only six companies including superstar entrepreneur Warren Buffet's Berkshire Hathway to trade above $500. So far today, the stock has reached an intraday high of $507.57.

Google stock is now some six times the $85 IPO price it debuted at in August 2004. In those two years, the market capitalization of the leading search and advertising company has grown from $30 billion to over $153 billion today. Analysts expect the stock to continue to climb, with price targets set as high as $600.
