With both Citigroup ( C) and JPMorgan posting poor fourth quarter trading results, it is hard to imagine how Bank of America could do much better. Even if it did, investors would probably view the feat as an unsustainable one-time event. No one is looking for Bank of America to turn into a trading powerhouse -- if such an animal can even be said to exist anymore given how severely new regulations (or merely the threat of them) have clipped the wings of Wall Street traders.

What analysts and investors are hoping to see from Bank of America is evidence that it is putting mortgage litigation risk behind it.

But how can the bank possibly provide such evidence? Don't expect positive news from negotiations between Bank of America and government-sponsored enterprises Fannie Mae ( FNMA.OB)and Freddie Mac ( FMCC.OB). Not when the Federal Housing Finance Agency, which oversees the mortgage giants, is under criticism from its inspector general for failing to challenge a $1.35 billion settlement between Bank of America and Freddie Mac over mortgage repurchase clams.

Some analysts are hoping for finalization of a long ago-proposed $25 billion deal regarding mortgage servicing abuses between the banks and attorney generals from a majority of the 50 states in the U.S. Still, a big settlement is hard to envision when attorneys general from several states, including New York, Massachusetts and Delaware, refuse to go along with a deal.

"We look forward to doing whatever it takes to obtain servicing reforms -- whether through a negotiated deal with banks or through regulations issued by the federal Consumer Financial Protection Bureau. But we will not release claims that we are currently investigating," wrote New York Attorney General Eric Schneiderman and his Delaware counterpart Beau Biden in an essay for Politico.

In addition to mortgage servicing, Schneiderman and Biden are investigating securitization, origination and "the Frankenstein's monster of a recording system called the Mortgage Electronic Registration Systems," they wrote.

JPMorgan, which has far fewer problems than Bank of America, saw its mortgage-related legal costs rise during the quarter, casting an ominous cloud over Bank of America's coming report.

Some analysts are hoping for resolution of Bank of America's proposed $8.5 billion settlement of mortgage litigation between Bank of America, Goldman, BlackRock ( BLK), Pimco and other large institutional money managers. But with Schneiderman, the FDIC and others arguing against the proposed settlement, it is hard to imagine the deal will go through as proposed.
