Greek stocks plunged 4.54 percent shortly after opening Tuesday, after showdown debt talks between Athens and its creditors collapsed, raising fears the country may crash out of the eurozone.
The benchmark Athex Composite index recovered to 828.88 points, or 3.59 percent off Monday's close in early trading, after a meeting of eurozone finance ministers in Brussels ended in disarray and with an ultimatum for Greece to present a solution by the end of the week.
However, the yield on Greece's 10-year bonds -- a common indicator of market sentiment -- was largely steady at 9.554 percent from 9.653 percent on Monday.
Greek Finance Minister Yanis Varoufakis held out hope that differences could be bridged within the next two days, with the possibility of another meeting on Friday.
"I have no doubt there is going to be an agreement in the end," Varoufakis said late Monday after the talks abruptly ended after only a few hours.
