Can the stock of Google, whose share of the Internet search market according to ComScore increased to 56.5% in August (from 55.2% in July) and who is striving to acquire DoubleClick for $3.1BN, reach $600, just three years after it began trading - at $85 - in 2004?

With the third-highest market cap (more than $180BN) of any U.S. technology company - Microsoft is #1 and and Cisco Systems is #2 - Google's share price this year alone has risen by 27%.

It now has the sixth-highest stock price in the entire U.S., having yesterday reached $596.81 on the Nasdaq Stock Market before settling to $584.39 at 4:00PM  New York time - a remarkable feat given the fact that the GOOG share price dipped below the $500 level in mid-August after the company missed its second-quarter earnings numbers in July. 

Today may just be the day that it hits $600.
