CAIRO: Mohamed Abdel Salam, Chairman of Egypt's Stock Exchange, said it is normal for companies' shares fall in reaction to bad news and said such a fall is temporary. According to the premise of supply and demand, shares will regain their value as investors realize the management of a business is separate from its owner, who may be subject to legal prosecution. Abdel Salam said prominent companies linked to businessmen involved in corruption crimes, such as Palm Hills, have professional managers which can lead the businesses. He added that the psychological impact is expected to effect shares but that they will bounce back quickly.
