Mortgage rates were little changed Thursday ahead of tomorrow’s key employment data. This morning, weekly Jobless Claims rose to 362,000, above the consensus forecast of 355,000. Stocks were boosted as investors became more optimistic that the Greek debt swap deal will be accepted by most private bondholders. Rates may be volatile tomorrow. Results from the Greek debt swap offer are scheduled to be announced at 1:00 AM ET and the Employment Report for February will come out at 8:30 AM ET. No other key data will be released today.
