Greek stocks may test new support levels in coming days after sliding more than 2 percent, with investors keeping an eye out for a slew of blue chip earnings figures due. On Friday, the Athens bourse’s benchmark general index slipped 3.53 percent to 1,589.74 points, falling below 1,600 points. On a technical level, brokers said continued selling pressure could push the general index to as low as 1,383 points before coming across stronger resistance. The earnings agenda is full this week, with Fourlis, Hellenic Petroleum and Motor Oil reporting tomorrow. On Thursday, OPAP, EFG Eurobank, Titan, PPC, Piraeus Bank and Sidenor are scheduled to unveil data. On Friday, its National Bank’s turn. Looking abroad, Wall Street is expected to limp through the summer doldrums with investors remaining on guard for more deterioration in what’s expected to be a light-volume week. The S&P 500 suffered losses last week and is in danger of falling through support due to continuing worries about economic data.
