The Athens bourse’s benchmark general index jumped 9.13 percent to 1,779.30 points, on the back of the biggest rise in bank stocks recorded in some 20 years.

Data released by Hellenic Exchanges, the operator of the Athens bourse, showed yesterday that foreign investors marginally increased their holdings in Greek stocks in April, despite falling share prices stemming from the country’s debt crisis.

In December, foreign players held 48.5 percent of Greek stocks. The blue chip FTSE/ATHEX 20 index gained 881.24 percent yesterday to 881.24 points.
