Are LEH and WM headed for Zero?

Mortgage rates have spiked lower dramatically.
How low will mortgage rates go? When the 2yr treasury note is yielding 1%, maybe we'll be closer to the bottom.
ZB is grinding higher, yields continue lower, and more financial stocks like LEH and WM go lower. You have to question the drop in yields in conjunction with the weakness in these stocks. Is the price action suggesting one or both of these stocks will go under. And if these companies go under what effect will this have on US treasuries. Definetily a spike lower will occur just like we saw with the Bear sterns bailout. The question is, if and when will it happen.
