The Kuwait Stock Exchange ended last week\'s trading with variance on its indices, a specialized economic report showed Saturday. The report, by Bayan Investment Company, pointed out that the price index and weighted indices ended the week trading in the red zone while the KSX-15 index moved to the green zone. Bayan data showed that the price index has incurred its first weekly losses in twelve weeks due to a wave of selling operations to collect profits which focused on many small-cap stocks. The price index also registered its biggest losses in one of last week\'s sessions, the report noted. The KSX-15 index managed to close the week up slightly backed by speculative purchasing operations on a number of large-cap stocks. This performance comes with the continued efforts of listed companies to announce its 2012 financial results and distributions before the end of the legal disclosure period, which will finish by the end of the current month amid traders\' cautiousness and fear of the possibility of having some companies stopped from trading if it doesn\'t meet the disclosure deadline date.
