Google's stock price has passed the psychologically important but otherwise meaningless $600 barrier for the first time. Want some other high-flying tickers? Try the Washington Post Company at $803 or Warren Buffett's Berkshire Hathaway — currently trading around $121,000 per share. Of course, despite the difference in absolute stock prices, Google and Berkshire Hathaway have roughly the same market capitalization — a perfect illustration of why the price of a stock, out of context, has no meaning.
