Saudi stock market's Tadawul All-Share Index (TASI) fell for a second day on Saturday pulled by heavyweight petrochemical and banking stocks TASI closed 0.56 percent down at 5,956.76 points. “The market right now is in a sideways movement ... many investors are waiting for the financial statements to come out in July and they are not interested in trading in the market at this time,” said Alhassan Goussous, head of private client portfolios at Rasmala Investment. Al-Rajhi Bank led the decline after being rated “equal-weight” at Morgan Stanley in new coverage.
