(Updates with GE results, Wall Street outlook, comments)
By Jeremy Gaunt, European Investment Correspondent
LONDON, April 11 (Reuters) - Worse-than-expected results from U.S. conglomerate General Electric <GE.N> turned a tentative stock rally on its head on Friday and added further pressures on the dollar.
The GE results underlined the extent of the slowdown in the U.S. economy just ahead of a Group of Seven finance and central bank meeting that hopes to draw a line under the credit crisis.
Wall Street looked set for a poor start after the report and European shares sank deeply into negative territory after earlier, relatively solid, gains.
The battered dollar extended losses against the euro and yen, while demand for government bonds rose.
GE reported an unexpected 6 percent drop in profit and lowered its earnings forecast for the year.
"These results confirm that the slowdown is widespread and beginning to impact capex (capital expenditures) and longer-cycle businesses," said Stephen Surpless, senior analyst at Cantor Fitzgerald in London.
"While the credit crisis might be nearer to the end than the beginning, according to some, the impact on the real economy is taking place and is unlikely to abate in 2008," he added.
The FTSEurofirst 300 <
> index of top European shares was down more than 1 percent, reversing an attempt to break a three-day losing streak.Its earlier gains, along with those in Japan where the Nikkei average <
> rose 2.9 percent, were based on optimism that the economic slowdown was not as bad as feared. Key retailer reports in the U.S. and Japan were relatively buoyant.G7 IN FOCUS
Investor focus was also on G7 finance ministers and central bankers who were to meet in Washington later in the day with calls from some, such as Bank of Japan Governor Masaaki Shirakawa, for the rich nations group to show it was prepared to ensure financial system stability.
They are expected to deploy an international team to keep closer tabs on the world's big banks and demand better risk management and information disclosure across financial markets.
Leading bank chiefs have been invited to the meeting to discuss the global markets crisis, which could cost close to $1 trillion in losses and downgrades in the value of toxic assets accrued over years of investor euphoria.
Currency traders, however, were sceptical that the G7 would do anything to prop up the dollar.
"Not very many people expect the G7 to come out with a very firm statement that could support the dollar, so we still have quite a negative dollar environment, especially when ECB didn't ease their concern about inflation," said Niels Christensen, FX strategist at Nordea.
The ECB held rates at 4 percent as expected on Thursday.
WEAK DOLLAR
The dollar extended losses versus the yen and the euro after the GE results
The dollar fell to 101.67 yen from around 101.95 before the GE results <JPY=>. The euro extended gains to $1.5823, up half a percent on the day <EUR=>.
"The GE results fed straight in to dollar/yen falling," said a London-based trader.
Money moved into safe haven government bonds, depressing yields.
