Goldman Sachs (NYSE:GS) shares are up over five percent today after the investment banking firm announced that it does not expect to take any significant asset write-downs this quarter. The news also boosted confidence in other financial stocks around the market, including Bank of America. Many investors are hoping that this will signal the end of the credit crunch.

"We're convinced we have a pretty good grip on [CDO and mortgage] valuations," said Blankfein at the Merrill Lynch Banking & Financial Services Conference after some investors voiced concerns about Goldman's valuations. The CEO assured investors that it has properly valued its assets. In fact, when the firm isn't certain, it has traders execute test trades to assign a value that has some merit.

Interestingly, Goldman also has a bearish view on the US mortgage markets where rising default rates and a lack of buyers has caused steep declines in mortgage values and derivatives like CDOs. The firm reported solid gains on its bets against the mortgage markets and indicated its belief that things will likely get worse before they get any better.

In the end, it appears the Goldman made the correct bet on the mortgage markets by positioning itself as net short. Whether or not the firm's valuations are correct remains to be seen, but it appears that the only factor they fail to fully consider is liquidity (after all, test trades don't account for that). Combined, these factors make GS a stock worth watching!
