Apple’s fiscal annus horribilis by Philip Elmer-DeWitt @FortuneMagazine September 29, 2013, 11:00 AM EDT E-mail Tweet Facebook Google Plus Linkedin Share icons FORTUNE — On Saturday, Apple AAPL closed its books on 2013 with shares down nearly 30% year over year. As harrowing as fiscal ’13 was for anyone holding the stock, long-time investors have been through worse. The company has made a lot of people very rich, but with Wall Street never sure if Apple’s best days are behind it, its valuation can turn on a dime. The stock’s greatest hits include: Sept. 2012 to April 2013: Down 42.8% Calendar 2008: Down 56.9% Jan. to July 2006: Down 38.9% Fiscal 2001: Down 39.8% Sept. to Dec. 2000: Down 77% Apr. 1991 to July 1997: Down 82.6% That’s as far back as my memory of the share price goes. If you’ve seen worse, let me know.
