* Global, emerging stocks supported by data, earnings
* Wall Street set for slightly lower open
By Jeremy Gaunt, European Investment Correspondent
LONDON, July 26 (Reuters) - Robust U.S. company earnings and surprisingly vigorous euro zone economic data generally trumped investor scepticism about European bank stress tests on Monday to support global stocks including banks.
Emerging market stocks hit a 2-1/2 month high although Wall Street looked set to open mildly lower after solid gains on Friday.
There was weakness on European bourses, but banking stocks <.SX7P>, the key test, were up a third of a percent on the first trading day after the release of stress tests, which showed most financial institutions to be in relatively good shape. [
]There was still concern that the tests were not tough -- by not considering sovereign debt default, for example -- but investors appeared content with the results.
The cost of insuring bank debt against default was cheaper, with the Markit iTraxx Senior Financials composite narrowing 2.5 basis points. Euribor interbank lending rates were barely changed.
"We interpret the bank stress test as positive. Disclosure is help not hindrance, therefore, we are overweight on banks. We do not expect a double-dip," said Gary Baker, head of European strategy at Bank of America Merrill Lynch.
Underlying investor sentiment has been lifted by a series of reports in the past week showing the broader European economy to be stronger than thought.
Purchasing managers' indexes indicated third-quarter euro zone growth of around 0.6-0.7 percent, double the 0.3 percent forecast in the most recent Reuters poll. German business sentiment also posted a record jump in July to its highest level in three years.
Non-euro zone member Britain added to the mix with an economy growing twice as fast as expected in the second quarter.
Wall Street also weighed in with some bullish news on Friday, when U.S. conglomerate General Electric <GE.N> increased its quarterly dividend by 20 percent.
The wide-ranging impact GE has on the U.S. economy, coupled with another round of strong earnings, bolstered investor confidence.
BofA's Baker said valuation in Europe was also "very reasonable".
World stocks as measured by MSCI <.MIWD00000PUS> were up 0.3 percent and the Thomson Reuters global stock index <.TRXFLDGLPU> gained about 0.2 percent.
The FTSEurofirst 300 <
> was flat.
EURO FIRMS
The euro erased most of its early gains against the dollar as caution set in and early risk-taking sentiment faded a bit.
"Any downside lurch has been prevented by the generally reassuring conclusions of the tests ... no surprises as to the vulnerabilities, and no real headache in terms of the required capitalisation to bolster their position," said Daragh Maher, deputy head of FX strategy at Credit Agricole CIB.
"At the same time, any relief rally for the euro has been curtailed by inevitable criticism about some of the deficiencies of the stress test assumptions." [
]The euro was flat compared with late U.S. trade on Friday at $1.2900 <EUR=>, falling from a session high of $1.2958.
Euro zone government debt was mixed, with short-term bonds selling off.
"We doubt ... that the stress test results will have a lasting impact on fixed income valuations, especially given the heightened focus on macro economic fundamentals," said Jamie Searle, analyst at Citi.
"The market will be watching for any further signs that double-dip concerns are overblown following Friday's strong German IFO and UK GDP numbers." (Additional reporting by Ian Chua, Natsuko Waki and Tamawa Desai; Editing by Susan Fenton)
