NEW YORK, July 22 (Reuters) - U.S. stock futures slid on Tuesday as disappointing outlooks from bellwethers, including Apple Inc <AAPL.O> and Europe's Vodafone <VOD.L>, increased concerns about weakening economic growth and more fallout from the U.S. housing slump.
Adding to the negative tone, Wachovia Corp <WB.N>, the fourth-largest U.S. bank, posted an $8.86 billion second-quarter loss and slashed its dividend to shore up its balance sheet as mortgage delinquencies rose. For details, see [
].The news from Wachovia, whose stock declined more than 10 percent to $11.80 before the opening bell, damped hopes the bank sector was stabilizing. In recent days stronger-than-expected results from major banks like Citigroup <C.N>, Wells Fargo <WFC.N> and JPMorgan Chase & Co <JPM.N> had fed those hopes.
Apple, also down more than 10 percent at $149.74, was poised to lead a technology sell-off, a day after the iPod and iPhone maker said its current-quarter earnings will be well below Wall Street's targets.
Apple's warning, along with a reduced revenue forecast from Europe's mobile phone company Vodafone, and a poor third-quarter profit forecast from chip maker Texas Instruments <TXN.N> underscored growing unease about slowing economic growth in the United States and abroad.
"We must have a slow economy because Texas Instruments, American Express and Apple are having a hard time," said Arthur Hogan, chief market analyst at Jefferies & Co in Boston. "Those are some household names, putting some pressure on stocks. Wachovia doesn't look positive."
S&P 500 futures <SPc1> slipped 11 points and were below fair value, a mathematical formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract.
Dow Jones industrial average futures <DJc1> fell 90 points, and Nasdaq 100 <NDc1> futures declined 32 points.
Dow component American Express <AXP.N> also reported a profit that missed Wall Street's estimates late on Monday. American Express shares were down 12.5 percent before the bell at $35.80.
In other bank news, SunTrust Banks Inc <STI.N>, a large U.S. southeast regional bank, said higher real estate losses led to a 21 percent drop in quarterly profit. SunTrust boosted capital from transactions involving the sale of a big Coca-Cola Co <KO.N> stake. [
