Mubasher: World stock markets are expected to make a jittery performance during the coming trading sessions as investors wait for the European central bank's view on its monetary policy.

Market analyst Tarek Hmad indicated that the coming days are a very sensitive trading period in a number of countries like France, Germany and Spain where elections are to take place.

"No doubt that the Brexit still occupies a great share of investors' sentiments that will lead, along with the fall of Eurozone composite PMI and speculations on Mario Draghi's speech over the EU monetary policy, to a wave of fluctuations in the world market", Hmad sadi.

The Composite PMI reached 52.6 points, which is the lowest level in 20 months.  

Further, the OPEC meeting that will start tomorrow for two days in Algeria plays a big role in the coming sessions as its outcome, whether a freeze deal is compromised, will affect the market's general trend, George Al-Batroni told Mubasher.
