Stocks on the Greek bourse yesterday slid to their lowest point since the 2004 Athens Olympics, as foreign investors decided to pull out, focusing on selling stakes in banks. This occurred despite the rather favorable climate on the main European markets. The Athens Exchange (ATHEX) general index closed at 2,117.41 points, declining by a significant 6.11 percent from Thursday. The blue chip FTSE/ATHEX 20 index shrank by 7.40 percent to end at 1,146.73 points. The biggest losses among blue chips were for the stocks of National Bank (down 14.42 percent), Viohalco (11.54 percent), EFG Eurobank (10.51 percent), Bank of Cyprus (9.34 percent), Titan cement (8.69 percent) and Alpha Bank (8.62 percent). The only blue chip to show gains was Coca-Cola HBC (up 4.23 percent). Turnover reached 369.6 million euros.
