Mortgage rates were little changed Friday as mortgage-backed securities recovered from yesterday’s late sell-off. This morning, Federal Reserve Bank of New York President William Dudley suggested that economic growth will accelerate during the second half of 2011, but will seem “painfully slow” for many people. May Import Prices rose 0.2%, the eighth consecutive monthly increase. Stocks moved sharply lower. Next week will be busy in terms of new economic data. The Producer Price Index (PPI) and Retail Sales will be released on Tuesday, the Consumer Price Index (CPI) and Industrial Production will come out on Wednesday. No other key data will be released today.
