Bahrain's Securities and Investment Co has said its second-quarter net profit plunged 80% to BD252,000 from a profit of BD1.28m for the previous quarter. The firm said it was affected by a drop in its trading revenues, in addition to a lack of client activities particularly in investment banking during a particularly volatile second quarter. However, net profit for the first six months of the year rose 64% to BD1.532m from BD935,000 for the first half of 2009.
