The big highlight of the holiday-shortened week will be Friday’s jobs report for May. Forecasters expect the S&P Case-Shiller home price index to show a continued decline in housing valuations in March, with an 0.2 percent decline in 20 major metro areas expected. That would represent a 3.5 percent decline over the past year. The Institute for Supply Management is scheduled to release its index of manufacturing activity which is expected to show continued decceleration of output at the nation’s factories.
