Analysts scramble to keep their targets ahead of Apple’s price by Philip Elmer-DeWitt @FortuneMagazine September 18, 2012, 1:01 PM EST E-mail Tweet Facebook Google Plus Linkedin Share icons FORTUNE — On Sunday BMO Capital’s Keith Bachman, citing “earlier availability” of the iPhone 5, raised the price he expects Apple’s AAPL shares to reach in the next 12 months from $680 to $750. He was already three days too late. The stock, which opened September at $665.76, smashed through $680 last Thursday, closed Friday above $691 and finished Tuesday at $701.91. Bachman is not the only Wall Street analyst having trouble keeping up with Apple’s share price. More than half of the analysts we track raised their 12-month price targets this summer into the 750-900 range ($770 is currently median target, according to Thomson First Call). We expect they’ll have to do it again before January. Meanwhile, we’ve got several analysts at exactly $700 and at least two — Pacific Crest’s Andy Hargreaves ($690) and Morningstar’s Michael Holt ($670) — well under water. At the other end of the spectrum, Topeka’s Brian White set a Street-high $1,111 target in April and seems to be sticking with it.
