For the coming week, economic data could support bonds, some say. The June NAPM is released Monday and estimates are in the 42-45 area, versus a 42.1 reading in May. Morgan Stanley economist David Greenlaw said "production problems at Ford and a further deterioration in the tech-related activity should help restrain the NAPM gauge," so he prefers an estimate at the lower end of the range of expectations. Also expected to be a market support is next Friday's June nonfarm payroll reading, where a drop of about 20,000 jobs is anticipated. Payrolls declined 19,000 in May and fell 182,000 in April.
