If there's one company that will hit a trillion dollar market cap, it will be Apple. Apple could do it in the next three years. USA Today came up with Apple's trillion dollar market cap based on its five-year average increase of 59% a year. So given today's market value of about $310 billion, if Apple continues to increase in value by 59% each year, in 2014, we'll have the first trillion dollar company. How huge is that? The most valuable company ever was Microsoft in 2000. That year it hit a $604 billion market cap.
But hey, I'm just a blogger. I don't have a degree in finance or economics. Though I'm sure you'll find many analysts who agree with me, there are probably plenty who won't.
