Apple topped $300 billion in market value Monday.
Apple continues to be the second most valuable U.S. company behind Exxon Mobil, which has a market cap of $375 billion (a 52-week high). Exxon's stock has been surging since April, and now trades at nearly $75 per share. It is off its all-time high of about $95 per share set in October 2007.
Apple could surpass Exxon's market cap by topping $410 per share, assuming Exxon's stock continues trading near current levels.
This remarkable run in Apple’s stock is really a story of the past three and a half years. Look at a chart: It took almost 23 years of trading for Apple to top $100 billion in market cap in May 2007. The next milestone came less than three years later – $200 billion in March of last year. Now, 10 months later, as Steve Jobs would say – boom. $300 billion.
