* U.S. consumer mood improves more than predicted in Aug
* Housing data mixed but traders focus on positives
* Financials rebound, led by Fannie Mae, Freddie Mac (Updates to midday)

NEW YORK, Aug 26 (Reuters) - U.S. stocks rose in light volume on Tuesday, as higher oil prices boosted the energy sector and a report showing a pickup in consumer confidence in August soothed anxieties about the economy.
A batch of fresh housing data was mixed, but investors focused on the less gloomy aspects of these reports in hopes they signaled a stabilization in the battered housing sector.
Financial companies that had fallen sharply on Monday on credit fears also bounced back, helping to support the market.
"It's fair to say two things: the economic data calendar gave us a mixed message today on balance, and the market may well be moving more on the fact that oil's up $2.50," said Arthur Hogan, chief market analyst at Jefferies & Co in Boston.
Energy companies led the S&P 500 higher as oil<CLc1> rose as much as 2.4 percent on concerns about possible disruption to oil and natural gas output in the U.S. Gulf from a strengthening Hurricane Gustav.
Exxon Mobil <XOM.N> was the biggest boost to the S&P 500, rising 1.1 percent to $79.55. The S&P energy index <.GSPE> was up 1 percent in midday trading.
The Dow Jones industrial average <
> was up 11.72 points, or 0.10 percent, at 11,397.97. The Standard & Poor's 500 Index <.SPX> was up 3.56 points, or 0.28 percent, at 1,270.40. The Nasdaq Composite Index < > was up 1.66 points, or 0.07 percent, at 2,367.25.Shares of Anadarko Petroleum <APC.N> jumped 6 percent after the company announced a share repurchase program of up to $5 billion.
The gain in the price of oil weighed on companies particularly sensitive to higher fuel costs, such as airlines. An index of airline stocks <.XAL> was down 1.5 percent.
HOUSING STABILITY
Tuesday's data on housing showed a record annual drop in home prices and rising delinquencies on mortgages, but also pointed to a slowing pace of price declines and a drop in hefty new-home inventories.
The Standard & Poor's/Case-Shiller national home price index showed prices of U.S. single family homes fell at a record pace in June from a year earlier, but the rate of decline slowed from May, suggesting the battered housing sector may be stabilizing. [
]."Things are improving," said Jack Ablin, chief investment officer at Harris Private Bank in Chicago. "But it's still going to take another year to work out the housing problem."
"Our housing crisis will become more of a regional issue," he added.
Nine of the 20 cities tracked in the S&P/Case-Shiller report showed increases in home prices in June, up from seven in May.
A turnaround in the housing market could go a long way to help consumers who have been saddled by high food and gas prices and a worsening job market.
The Conference Board's consumer confidence index rose to 56.9 in August from 51.9 in July, above the 53.0 forecast by analysts polled by Reuters. [
]On the Nasdaq, Marvell Technology Group <MRVL.O> shares fell 7.4 percent after Jefferies & Co. downgraded the stock on concerns about the microchip design company's hard disk drive inventory and its weak cellular positioning.
Among big board shares, embattled mortgage finance giants Fannie Mae <FNM.N> and Freddie Mac <FRE.N> rallied on speculation any rescue would not wipe out shareholder value.
"I think there's a lot of speculation that maybe the shareholders will get bailed out. So shareholders think, 'If I buy this at $3 to $5 a share and the shareholders get bailed out, I'm going to do great.' They're certainly not doing it on the basis of fundamentals," said Mark Coffelt, chief investment officer at Texas Capital Value Funds in Austin, Texas,
Fannie's shares rose 12 percent to $5.80 and Freddie's shares jumped 20 percent to $3.96.
