Apple shares back in vogue as Wall Street bets on iPhone surge

Wall Street has regained an appetite for Apple as investors bet that the release of a 10th-anniversary iPhone and pent up customer demand will shore up shrinking sales. The largest component of the S&P 500, Apple remained a core holding of Wall Street throughout a decline in the stock in the first half of last year. Apple's 15-percent rally since mid-November pushed the stock to levels not seen in more than a year and boosted over 100 mutual funds that became shareholders in recent quarters.
