Marginal changes are recorded on the Greek stock market, with the market in a wait-and-see attitude ahead of the Fed's verdict on Wednesday regarding interest rates, while the positive outlook from Moody's should be taken into account for the investment climate while there may be some selective interest after Friday's recovery.

In this climate, the General Index gained 0.13% to 1,419 points, with turnover at 5.204 million and trading volume at 1.19 million shares.

Moody's upgraded the outlook of the Greek economy to positive from stable, while maintaining the Greek sovereign rating at "Ba1". Moody's is the only house that has not yet given the investment grade to our country. According to the house, the main factor that led to the outlook upgrade is the performance of Greek banks.
