LONDON, April 17 (Reuters) - World stocks climbed towards their sixth consecutive week of gains on Friday and Wall Street looked set to join in after General Electric <GE.N> and Citigroup <C.N> posted better-than-expected earnings. The dollar also climbed, hitting a one-month high against the euro.
MSCI's all-country world stock index <.MIWD00000PUS> was up 0.2 percent with both Europe and Japan gaining more than 1 percent. The world index was up 1.8 percent on the week, gaining more than 29 percent since a March 9 low.
GE and Citi joined the likes of Goldman Sachs, JPMorgan and Google in issuing earnings reports that, at the very least, were less bad than feared. [
] [ ]Such results have added to increasing optimism that equity markets and economies have hit bottom.
European Central Bank President Jean-Claude Trichet said the battered global economy faces a difficult year but will begin a recovery in 2010. Other central bankers have also noted some signs of stabilisation. [
]A jump in Chinese industrial output in March has added to a sense instilled by some U.S. indicators that the pace of deterioration has slowed from the alarming rate of just a few months ago.
Investors have taken note.
U.S. financial services firm State Street said evidence was building that big investors are now buying into the rally, particularly in U.S. and emerging market stocks.
"It seems the nightmare may now be ending. Markets have been having quite a party of late," State Street said in a note. "Institutional investors are backing this rally."
The pan-European FTSEurofirst 300 <.FTEU3) was up 1.2 percent. Earlier, Japan's Nikkei <
> gained 1.7 percent.
EURO DROPS
The euro fell to a one-month low against the dollar on concerns about the health of the euro zone economy after Moody's said it may cut Ireland's sovereign debt ratings.
Moody's said Ireland's prized 'AAA' rating may be cut to mid-to-high Aa range if it concludes that the country will emerge from the crisis with "relatively weak growth prospects and a much higher debt burden". [
].Ireland has already lost its top-notch rating status from the other two major ratings agencies, S&P and Fitch.
The single currency had already been reeling from earlier comments from Trichet that he appreciated U.S. policymakers saying a strong dollar was in U.S. interests, and that to say the euro is weak "doesn't reflect the current situation". [
]The euro was at $1.3044 <EUR>, down 1 percent and at a one-month low against the dollar.
The two-year Schatz yield <EU2YT=RR> was up 4 basis points at 1.420 percent after marking an intraday high of 1.472 percent and underperforming other issues.
The 10-year Bund yield <EU10YT=RR> was up 1 basis point at 3.193 percent.
