Tel Aviv stocks are opening down 1% Sunday, after closing with mild gains on Thursday. The negative mood is attributed to Friday's suicide bombing in Jerusalem, in which six people were killed and 86 injured.

S&P said the reduction to negative, which raises the likelihood of a credit rating downgrade, came in spite of an improved outlook for the global economy.
