The Financial Post reports in its Tuesday edition that the U.S. Federal Reserve-induced sell-off in tech stocks has traders dusting off their turmoil playbooks. A Bloomberg dispatch to the Post says that one of the most popular strategies, however, is not working: buying Apple. Recent weeks have seen the stock fail to live up to its reputation as a haven. Concerns over China and recent growth trends -- coupled with Fed policy that has contributed to the tech sector falling into a correction -- have erased nearly $270-billion (U.S.) in value in September alone. Since the end of July, Apple is down almost 13 per cent, compared with the Nasdaq 100's 6.6-per-cent decline as of the end of September. While Apple is not immune from the economic backdrop and faces headwinds of its own, its slide has not changed characteristics that have traditionally drawn investors, including Warren Buffett, to it in times of uncertainty, thanks to its rock-solid balance sheet and durable revenue streams. The stock is seen winning favour if a bleaker economic outlook leads investors to sour on more speculative plays. Jack Ablin at Cresset Capital said, "Its fundamentals are so solid that it is basically the Treasury of the equity market."
