Apple's stock can't seem to catch a break lately.
Shares are off another 4 percent today, and Apple has lost a fifth of its market value since shares peaked in mid-September. It closed down 6.4 percent to $538.79, but is up slightly in after-hours trading.
Over the past few months, Apple has faced questions about whether it can maintain its current dominance in the mobile industry, with its iPhone and iPad both ceding market share to devices running on Google's Android operating system. At the same time, investors are fretting over the decline in profit margins at the company, which executives believe is a temporary hiccup spurred by the introduction of so many different products.

Apple's shares did pop briefly in late November as the company improved its supply of iPhones and entered the crucial Black Friday-Cyber Monday shopping frenzy. Several analysts noted that iPhone production yields have improved, which could lead to better sales. But the stock's return to decline this month suggests there remains some skepticism and concern over Apple's next big growth driver.
