The Capital Market, during the last period, has suffered from non-based and notorious rumors, which had a negative effect on the smooth operation of the market. All the members of the market and especially the brokerage firms- traders, stock exchange representatives and the staff -have the duty, not only not to spread such rumors, but also to belie them when these rumors are created. Today, all the members of the market and the society must contribute to the smooth operation of the market, in the interest of the investors.
