Good news, bad news:

Although Wachovia Corp. (WB) (WB) has been mentioned as one of the more troubled big U.S. banks, at least some analysts believe it is not at risk and is unlikely to suffer the same fate of Washington Mutual Inc. (WM) They also believe that Wachovia will be able to survive on its own, without merging with another big financial institution.

Still, shares of the Charlotte, N.C.-based bank plunged Friday as investors, the day after WaMu’s failure, shifted their focus to other financial institutions that also suffer under the weight of mounting losses tied to toxic assets.
