Tel Aviv stocks gently subsided to end the dull Monday session with a negative bias, after posting mild gains at mid-day. Investors were by and large at the beach, in Israel or elsewhere. The few in action are waiting for more news on talks between the Hamas and Fatah organizations, on stopping terror attacks within Israel proper meaning, attacks could continue in Jewish settlements. Anyway, European markets are edging up today and Wall Street gained ground late last week, lifting the mood on the Tel Aviv Stock Exchange. Nonetheless, the Maof-25 index ended down 0.6% and the TA-100 index lost 0.5%. Tech stocks fluctuated around the flatline and finished down 0.2%. The total volume of trade was a watery NIS 132 million, rather better than the embarrassing NIS 83 million of Sunday, a sum last seen during the Passover holiday. With such languid activity, no clear trends can be discerned, commented a source at the Meitav investment house. Retailers are attracting at least some interest, after Supersol's sorry report for the second quarter. Leader & Co analyst Ori Hershkovitz today upgraded both marketing chains Blue Square and Supersol to Buy from Neutral, which had the first rallying by 1.8%. Supersol rose 0.8%. Koor Industries (NYSE, TASE:KOR) subsidiary Telrad Networks announced a $32.5 million megadeal to sell gear to ICE, the Costa Rican electricity company which also has a communications division. For comparison, Telrad's revenues for the first quarter were $39 million. Koor lost 1% despite the happy news, after reversing morning gains. Discount Investment Corporation (TASE:DISI) reversed its positive trend from Sunday, losing 0.3% after gaining 1.8% Sunday on the good second-quarter statement from Cellcom, in which it owns a 25% stake. Cellcom said it netted NIS 153 million on revenues of NIS 1.3 billion, as predicted. Teva (Nasdaq:TEVA) lost 1% on turnover of NIS 24 million.
