Apple, bellwether for technology stocks across Wall Street, dips into bear market territory

Investors have grown concerned that the company will suffer declines in iPhone unit sales over the next couple years. "You're talking not just about what Apple represents, but its effect across the whole food chain, including semiconductors," said Apple analyst Daniel Ives. Shares of Apple AAPL , a bellwether for the technology sector, dipped into a bear market on Wednesday as the decline from its recent all-time high briefly totaled more than 20 percent.
