NEW YORK, Aug 6 (Reuters) - U.S. stocks fell on Wednesday, led lower by financial shares after home finance company Freddie Mac <FRE.N> posted its fourth straight quarterly loss and braced for more fallout from the housing slump.
Freddie Mac's weaker-than-expected loss dealt investors a blow a day after Wall Street had its biggest one day advance in four months.
Freddie Mac said it was setting aside twice as much money for bad loans and made plans to slash its dividend by at least 80 percent. For details, see [
]. Its shares fell 16 percent, while bigger rival Fannie Mae <FNM.N> declined 12 percent.The two, known as government-sponsored enterprises and holding or guaranteeing nearly half of the $12 trillion in U.S. mortgages, have been pummeled by the housing downturn. The S&P 500 financial index <.GSPF> fell 2 percent.
"Freddie Mac was not a vitamin pill this morning. It clearly wasn't good news," said Stephen Massocca, co-chief executive at San Francisco-based investment bank Pacific Growth Equities.
"When you lower the dividend, people get out of the stock for that reason."
The Dow Jones industrial average <
> fell 66.52 points, or 0.57 percent, to 11,549.25. The Standard & Poor's 500 Index <.SPX> declined 7.46 points, or 0.58 percent, to 1,277.42. The Nasdaq Composite Index < > slipped 10.18 points, or 0.43 percent, to 2,339.65.U.S. front-month crude <CLc1> was up 49 cents at $119.62 a barrel on the New York Mercantile Exchange. Weekly U.S. oil inventory data is due at 10:35 a.m. (1435 GMT).
Some investors, doubting stocks will sustain gains, also book profits after Tuesday's broad surge, sparked by a drop in oil to three-month lows and hints from the Federal Reserve it will be in no rush to raise interest rates.
Freddie Mac shares dropped to $6.78, while Fannie Mae declined to $11.93. Both trade on the New York Stock Exchange.
Shares of insurer American International Group <AIG.N> , a gainer on Tuesday in the financial sector, fell 5.2 percent to $28.33.
Among banks, shares of Bank of America Corp <BAC.N>, fell 2.8 percent to $32.65. Freddie Mac, which also announced plans to slash its dividend, doubled its reserves for losses on delinquent loans and home foreclosures.
Last month fears that Freddie Mac and Fannie Mae, critical players in the U.S. housing market, faced capital constraints roiled markets and resulted in a sweeping rescue effort by Washington to bolster their finances.
On Nasdaq, shares of Apple Inc <AAPL.O>, the iPod and iPhone maker, fell 1.1 percent at $158.92. But Nasdaq losses were limited by a 4.2 percent rise to $23,59 in Cisco Systems Inc's <CSCO.O> shares, a day after the network equipment maker said it expected the weak economic environment to be relatively short.
