Tehran Stocks Extend Gains on Trade Optimism

Tehran stocks closed higher for a second straight session on Monday, supported by expectation of improved global trade atmosphere in the wake of the China-US trade truce and hike in international oil prices. 
The optimism lifted recently-battered major stocks back to the top: export-oriented minerals, metals and refinery stocks which are expected to benefit from the new ambience. 
The truce between US and Chinese leaders on trade tariffs also boosted global markets on Monday, fuelling an advance of nearly one percent by world stocks, setting up gains on Wall Street and pushing emerging-market currencies higher against the dollar.
