In 1999, Microsoft became the first company to close with a market capitalization of $600 billion, as USA Today Money reports. Market capitalization is a company’s stock price multiplied by the number of shares outstanding. Since 2007, Apple’s market value rose from $100 billion to $700 billion in 2015, which many analysts consider a significant valuation.

The highest stock price of all time belongs to Berkshire Hathaway, which once rose to $195,000 per share. Warren Buffett, the billionaire value investor known for his idiosyncrasies, is the founder of Berkshire Hathaway. As of 2015, the company trades just below its all-time high. In 2000, the Chinese energy and oil company PetroChina reached an estimated market value of $1 trillion prior to its initial public offering, according to Investopedia. However, unlike for Apple analysts included shares privately held by the company and not open for public trading. Other companies, such as Cisco, reached market capitalizations of $500 billion during the Internet boom of 2000, but they could not sustain their values.
