Financial shares rose after President George W Bush dropped a threat to veto a housing rescue bill, clearing the way for measures aimed at stabilizing the battered housing market, which has been the source of huge losses for financial companies.

Removal of the presidential veto threat spurred investors to snap up shares of Fannie and Freddie, the top two US housing finance companies, which would receive an emergency government lifeline under the bill.

After the closing bell, the US House of Representatives approved the housing market rescue legislation. The bill will now go to the Senate.

Oil prices fell more than US$4 (S$5.46) after government data showed a big increase in US inventories of gasoline, boosting companies sensitive to higher fuel costs, such as retailers and airlines.

'We're getting some positive spin from the lower oil price and also from the comments from the legislature on Fannie and Freddie,' said Mr Paul Nolte, director of investments at Hinsdale Associates, in Hinsdale, Illinois.

'And while earnings in general have been poor, investors are still welcoming these results. It's the analogy that if I was expecting you'd get a 'D' in math and you got a 'C,' I'd be pleased - even though it's still only a 'C'.'

The Dow Jones industrial average rose 29.88 points, or 0.26 per cent, to 11,632.38, while the Standard & Poor's 500 Index gained 5.11 points, or 0.40 per cent, to 1,282.11, a three-week closing high. The Nasdaq Composite Index was up 21.92 points, or 0.95 per cent, at 2,325.88.

After the closing bell, Amazon reported quarterly net income doubled from a year ago and beat Wall Street targets, though much of the gain was related to the sale of European DVD rental assets.

The online retailer's shares initially jumped more than 8 per cent following the results, but quickly traded down to be about 2 per cent below their closing price of US$70.54 During the regular session, U.S. crude oil for September delivery fell US$3.94 to US$124.48 a barrel. While the drop in crude boosted the broader market, shares of major oil companies, such as Exxon Mobil, fell. Exxon shares shed 2.3 per cent to US$80.99 and were the top drag on the S&P 500.

Robust results from Dow component AT&T that showed stronger-than-expected wireless growth helped boost technology shares. Apple Inc led the Nasdaq higher after AT&T, the exclusive US network carrier for the iPhone, said the launch of the iPhone 3G was strong.

But earnings reports painted a mixed picture. A drop in the shares of Boeing Co, another Dow component, kept gains in check on the blue chip index after the planemaker reported a bigger-than-expected drop in profit.

Boeing fell 3.7 per cent to US$66.72.

Industrial conglomerate Caterpillar fell 3.4 per cent to US$72.42 after JPMorgan downgraded the company, citing the possibility that volumes may slow further in North America and Europe.

Financial shares rose, with the S&P financials sub-index up 1.8 per cent. Shares of Freddie Mac jumped 11.3 per cent to US$10.80, while Fannie Mae climbed 11.9 per cent to US$15.

Home builders also headed higher on optimism about the housing bill, pushing the Dow Jones home construction index up 3.5 per cent. Shares of luxury home builder Toll Brothers rose 3.4 per cent to US$21.08.

Nolte and other analysts noted that given the Securities and Exchange Commission's clampdown on certain types of short selling in financial companies, some hedge funds were reversing the popular long-oil/short financials trade, heightening gains in financial stocks and the decline in oil.

Shares of AT&T, the largest US telecommunications company, jumped 3.9 per cent to US$33.06.

On the economic front, Federal Reserve said in its Beige Book that the pace of economic activity slowed somewhat through mid-July.

Trading was moderate on the New York Stock Exchange, with about 1.7 billion shares changing hands, below last year's estimated daily average of roughly 1.9 billion, while on Nasdaq, about 2.69 billion shares traded, above last year's daily average of 2.17 billion.

Advancing stocks outnumbered declining ones by 5 to 3 on the NYSE and by 4 to 3 on the Nasdaq. -- REUTERS
