You're looking at a graph of the basis, useful because not only does it give you the day's price action in Fannie Mae 5.5's, but also the 10 year treasury, so you can see how we started the day lagging a bit and then came back as the financial sector nausea began to subside.
We closed out right at 101-00, which is 2 ticks up on the day. Lenders will probably be trickling in with reprices for the better, especially those that repriced for the worse this morning.
