Morgan Stanley, announcing quarterly results earlier than expected, reported a profit that declined slightly but blew past analysts' earnings expectations as the No. 2 investment bank attempted to show that it's withstanding the financial turmoil that has dramatically changed the face of Wall Street over the past few days.

Excluding items, the investment bank said it earned $1.41 billion, or $1.32 a share, on sales of $8.05 billion in the third quarter.
