* Investors no longer taking traditional "convergence bets"
* Focus shifts to fundamentals rather than euro target dates
* Investment flows not likely to return to peak levels
* Czech debt seen more attractive than euro periphery

PRAGUE/LONDON, Feb 24 (Reuters) - Investors in the European Union's east have mostly abandoned "convergence bets" based on when they think the bloc's emerging members will adopt the euro and are instead focusing on the fundamentals of each economy.
Greece's debt blowout and ballooning budget gaps have wrongfooted many forecasters who must now decipher murky signals on euro zone enlargement from both the currency's core countries and its aspirants.
Latest Reuters polling shows most economists see the biggest candidates -- Poland, Hungary, the Czech Republic, Romania and Bulgaria -- joining in 2015 at the earliest, mostly a year later than they did late last year.
Those dates, though, are not necessarily reflected in market augurs that once served as the best indicators of expected adoption, so money managers are taking a country-by-country approach.
"Any talk of euro convergence is totally on the backburner when people are questioning the future of euro in the first place and second, when there is a possibility that one member of the euro zone may be thrown out," said Jason Manolopoulos, who manages $100 million in emerging Europe at Dromeus Capital in Athens.
"I like some of the stories like Poland, but I go in there not for the convergence but for the relative value."
The picture is a contrast from five years ago, when fund managers piled into the region with an eye to a date, not too far off, when the countries would join the euro, their interest rates and bond yields converging with those of the euro zone.
FORWARDS DIVERGE
Convergence has never been just about joining the euro. All of the region's emerging economies are expected to make steady progress in bringing wages, purchasing power and asset values in line with their developed neighbours and the idea of such "convergence" has drawn investors for about a decade.
A popular trade involved five-year five-year forward bond and interest rate swaps, showing at what level the market believes five-year interest rates will be five years from now.
For a country expected to adopt the euro in five years, they would show its rates close to the euro zone's. But even with the steady retreat on euro entry targets, this trade has been hugely profitable given that, for example, Polish 10-year bond yields were 13 percent in 2000, versus about 6 percent now.
That points to a bigger issue: much of the convergence of asset values is already done for some countries.
There is still room for the Poles and Hungarians to converge toward core euro interest rates -- on bunds or French bonds -- but the Greek crisis has underlined that there is now a greater difference in fiscal balance sheets and 10-year bond yields between some euro members than with those countries outside of the zone. Polish 5- and 10-year bond yields are already lower than those in Greece.
"You don't know if the euro is going to be there in five years and, second, we have increasing deconvergence within euro area so are you converging towards Greece or the Netherlands?" said Danske Bank Chief Emerging Markets Analyst Lars Christensen.
Another issue is that the candidate states themselves are not that keen on shackling themselves to a currency they cannot let depreciate to boost competitiveness in times of crisis.
The Reuters poll showed only Estonia likely to join any time soon -- next year -- while its Baltic neighbours are set for entry in 2014. The others are seen in 2015 or later but analysts say in reality there is as little if not less certainty now than there was when Poland and Hungary were forecasting they would join in 2008. [

"Any forecast you have to take with a large pinch of salt," said Nigel Rendell, a strategist at RBC. "There are so many variables, and each variable is unpredictable, with politics being the biggest element."
None of which is to say the convergence trade is completely dead. Joining the euro still has advantages -- low interest rates, a stable exchange rate and less exposure to speculative attacks.
Societe Generale fixed income strategist Esther Law expects both Warsaw and Prague could adopt the euro by 2015 and suggests receiving Polish 5y5y forward versus euro from around 130 bps.
She says the Polish five-year yield in five years time should be 5.6 percent if Poland joins the euro -- 120 bps below the current 5-year bond yield five years forward.
"Convergence may not make sense but that doesnt mean spreads won't come in," said Danske Bank's Christensen.
