Just one losing session out of four last week was enough for the Greek bourse’s main index to end up on the down side. The Athens Exchange (ATHEX) general index closed the week on Friday at 1,926.54 points, recording a 2.37 percent drop on the previous week’s close. Yet what was the dominant feature of the week was the shift of investor focus to the medium- and small-capitalization indices, as banks left the limelight and turnover dipped. The global sentiment has remained positive but it remains to be seen whether any political uncertainty in Greece could harm the local market in the medium term. Bourse observers note that the rise could continue, given that those who want to cash in on the recent rally are doing so selectively and in no hurry, which has allowed indices to maintain the bulk of gains on most days. Investors are already waiting to see the news emerge from US banks next week, which is likely to have a great impact on the course of international markets.
