This will just be a prologue for the rest of the day.  MBS is dead even on the day so far as we wait for the stock market to open and for the moderately important ISM non-manufacturing survey index. 

ISM is the only scheduled data for today, so the stock market will play a role today in the direction of MBS.  Since we are waiting for both stocks and the scheduled economic data, we'll reconvene in about an hour with more details.
