Tehran Stocks End Week Mixed 

Smalls caps and penny stocks were in upbeat mode in the last trading week ending Wednesday outpacing shares of giant commodity stocks for the second straight week. 
However, the main index of Tehran Stock Exchange, the market cap-weighted TEDPIX, posted negative returns and was down 9,000 points or 0.6% during five trading sessions. 
The TSE’s benchmark stumbled as most large caps were under sell-side pressure due to a combination of factors, namely decline in the international price of commodities and downturn in domestic currency market, which is often a bane for export-oriented listed companies.
