By MATTHEW CRAFTNEW YORK (AP) â¿¿ The big worry a year ago was that Greece would collapse under its debts, upend Europe's markets and set off a global financial crisis. But the world's most dangerous bond market turned out to be one of the world's best bets last year: Greece's government bonds soared 97 percent as the debt crisis eased. Across Europe, many of the region's stock markets outpaced those in the U.S. "It has been a great investment opportunity, because a year ago at this time Europe was a big mess," said Geoffrey Pazzanese, who manages an international stock fund at Federated Investors. The worst is likely over, most investors say. And that's where any agreement ends. A lot appears to be going right in Europe's financial markets. Greece is no longer a threat, banks are looking stronger, and government borrowing costs are down. Yet Europe's economy remains in a slump. The 17 countries that share the euro currency recently slid into their second recession in three years, and the European Union's statistical agency reported Tuesday that the unemployment rate had reached a new high of 11.8 percent. Either the pain will pass and markets will continue surging ahead, investors say, or it's going to be a painful slog for many more years to come. "It looks like the Greek meltdown scenario is off the table," Pazzanese says. "I'm just not sure Europe is back from the dead yet." Greece and the European debt crisis no longer topped Wall Street's list of worries by the end of the summer. Traders turned their attention to the danger that a package of budget cuts could push the U.S. into a slump in 2013. The turning point came in September when the European Central Bank pledged to stand behind the hardest hit countries and protect the euro currency. Mario Draghi, the head of the ECB, said the bank would buy the bonds of struggling governments once they sought rescue loans and agreed to the terms.
