Tehran Stocks Open Week Lower

Tehran stocks opened trading week on Saturday lower to extend a four-day losing streak and post the biggest daily loss since the beginning of new fiscal year (started March 21). 
The main index of Tehran Stock Exchange, TEDPIX, shed 11,573 points to lost 0.9%, closing the session at 1,282,984 points. 
Sell side pressure mounted on blue chips and commodity stocks during the session as decline in foreign exchange rates further weakened investor sentiment.  
Commodity stocks account for about 60% of the Tehran's share market comprising mainly export-oriented companies whose value is highly sensitive to the dollar. The US dollar dropped 4% on Saturday.
