Tehran Stocks Continue Rally

Tehran stocks started trading week in positive territory as commodity stocks gained traction amid upbeat trends in international markets and positive signals from domestic political developments. 
The main gauge of Tehran Stocks Exchange gained more than 5,400 points on Saturday, climbing nearly 2% to extend a winning streak into the fourth day.  
Reviews by the analytical website Donyaye Bourse show the recent bull markets are triggered more by sentimental behavior than fundamental factors.
Sentiments are more intense for small stocks, causing remarkable jumps in share prices in recent days and running the risk of creating price bubbles.
