German Stocks Tumble on Greek Impasse

The DAX retreated 1.8 percent to 7,789.24 in Frankfurt, its lowest level since April 24.

“Even Greece may have to come back for more money once again,” Ion-Marc Valahu, co-founder and fund manager at Clairinvest in Geneva, wrote in an e-mail. “The DAX, as much as other equity indexes across the world, is catching up to poor macro-economy fundamentals. All the liquidity poured in by central banks across the world only managed to delay the correction process.”

In Greece, Prime Minister Antonis Samaras lost one of his two coalition partners over his closure of state broadcaster ERT, sparking concern about the government’s stability that sent bonds and shares sliding. The Democratic Left party instructed its ministers to quit Samaras’s government.
