NEW YORK, Aug 18 (Reuters) - U.S. stocks fell on Monday as investors fretted about the prospect of more losses from the mortgage crisis, bruising shares of the two big U.S. home finance providers and other financial companies.
A one-two punch of gloomy financial news undermined market sentiment on Monday and reminded investors that the credit crisis and housing slump were far from over.
Shares of mortgage finance giants Fannie Mae <FNM.N> and Freddie Mac <FRE.N> each fell more than 16 percent after a Barron's report suggested the U.S. Treasury may recapitalize the companies, a move that could dilute the value of stock holdings.
The Treasury Department responded by saying it had no plans to backstop either of the two companies, but Freddie shares still dropped to their lowest level since July 15. For details, see [
]Meanwhile, the Wall Street Journal reported that some analysts are bracing for investment bank Lehman Brothers <LEH.N> to report a third-quarter loss of $1.8 billion or more. Its stock fell over 3 percent. For details, see [
]The Standard & Poor's Financial Index <.GSPF> was down 2.3 percent, reversing two consecutive sessions of gains.
"Investors have been trying to put the housing and credit crisis behind them. They want to believe we're in the eighth or ninth inning, but every time news like this comes up, they have to readjust their thinking," said Paul Nolte, director of investments at Hinsdale Associates in Hinsdale, Illinois.
The Dow Jones industrial average <
> slid 115.05 points, or 0.99 percent, to 11,544.85, off its session low at 11,527.18. The Standard & Poor's 500 Index <.SPX> dropped 10.91 points, or 0.84 percent, to 1,287.29. The Nasdaq Composite Index < > sank 23.83 points, or 0.97 percent, to 2,428.69.U.S. crude oil for September delivery <CLc1> was down 32 cents at $113.45 per barrel, although investors said its price fluctuations were taking a back seat to financial concerns.
Freddie Mac shares plummeted 16.1 percent to $4.90 on the New York Stock Exchange, while those of Fannie Mae slid 16.8 percent to $6.56. Merrill Lynch slashed its price target on Freddie Mac to $5.75.
Lehman Brothers shares declined 3.5 percent to $15.61 on the NYSE. According to the Wall Street Journal, if losses keep piling up, Lehman could need to raise additional capital beyond the $6 billion it got in June.
