Mortgage rates were little changed Thursday in volatile trading as investors attempted to analyze conflicting economic data. Weekly Jobless Claims rose sharply to 484,000, far above the consensus forecast. The April Empire State index surged to 31.9. A reading of 24.0 had been expected. Industrial Production increased just 0.1%, well below expectations. Stocks were mixed. Mortgage-backed securities prices have improved from earlier lows. Favorable re-pricing may occur.
