Poor Apple. Investors continue to hammer the stock, even after they posted their best-ever revenues and profits. Because of this pounding, Apple's market cap has been shrinking and it finally has shrunk enough that Exxon Mobil has regained the title of most valuable company in the world.

Apple's stock prices have fallen to $439.88 at the close of the market, giving Apple a market cap of $413.06 billion. Not too shabby. Exxon Mobile, on the other hand, has a market cap of $418.23 billion. Last January is when Apple took over the top spot as most valuable company, taking it away from Exxon Mobil.

Apple's stock has plunged from the $510 it was before the earnings report came out. Investors are fearful of competitors, such as Samsung, who are quickly gaining ground on the company. They also don't like that Apple's profits are increasing as quickly as they used to be. How low do you think Apple's stock will fall? Let us know in the comments!
