Greek stocks were nearly 4% down in midday trade in a turbulent week on the Athens exchange, after the end of a five-week shutdown sparked the biggest drop in its history.
The ATHEX index was losing 3.96% and stood at 633.78 points, with Greek bank suffering for a third straight day.
The bank index was down 21% and three of the main four lenders were near the maximum allowed drop of 30%.
Piraeus Bank and Alpha Bank were losing over 29%, Eurobank was over 26% down and National Bank was nearly 9% in the red.
The Athens market reopened on Monday five weeks after the government imposed capital controls to prevent a bank run and stave off financial collapse at the height of its standoff with EU-IMF creditors over a new bailout.
The Greek government and European Commission chief Jean-Claude Juncker have expressed hope that debt-crippled Greece and its creditors will reach a deal on a new rescue package in time for 20 August, when it is due to pay the European Central Bank €3.4 billion.
