Professor Eugene Kendall, chairman of the National Economics Council, said that the believed that the recommendations of the government committee against economic concentrations and oligopolies, if enacted, would have a major effect on four large Israeli conglomerates. Among those that will have to decide if they want to actively companies or give up a controlling financial role in those companies will be Nochi Dankner, who owns IDB Holdings, Supersol, Cellcom, Machteshim and others, and Yitzchak Tshuva, who owns Delek, real estate companies, and the Phoenix insurance company.

The report of the committee is not final. On Monday, stocks of the companies associated with the groups expected to be affected fell significantly.
