Selling has been steady, and there are no new market movers causing additional selling, but the gradual decline now brings 5.0 UMBS down an eighth of a point from AM highs.

Technically, this is the threshold scenario for negative reprice risk, but most lenders tend to price more conservatively on a day like today (which could limit some of the reprice risk we'd typically see in this situation).
