At $400 billion, Apple is worth more than Greece

Apple’s value on the stock market briefly rose to $400 billion on Thursday, a record high for what was already the world’s most valuable technology company.

The company’s market cap slipped below the $400 billion mark by midday as Apple’s (AAPL, Fortune 500) stock fell back from the all-time high of $431.37 it set earlier in the morning. Shares ended the day slightly down, leaving Apple with a $398 billion market value.

Apple’s market cap is higher than the gross domestic product of Greece, Austria, Argentina, or South Africa. (For more comparisons, check out this excellent blog: Things Apple is Worth More Than.)
