Stocks and bonds had a logical response to the threat of global nuclear war overnight, but even at the height of that trade, the gains weren't too big for Treasuries/MBS. Starting at 9am ET, bonds began giving back the overnight gains and that process continued in a slow and steady way throughout the session. MBS ultimately hit unchanged levels and 10yr yields rose roughly 6bps from the lows. The stock market made an even bigger round trip, ultimately ending higher for the 2nd day in a row.

Lock / Float Considerations
The burden of proof remains on economic data to make a case for any significant improvement in rates. In other words, don't expect big, sustained improvement without markedly weaker data/inflation. This doesn't mean rates can't drop here and there, but it does mean there's not currently a reason for them to drop very much or for very long unless data makes a case for it. The best hope over the last 2 weeks of November is for volatility to subside and for the prevailing uptrend in rates to run out of steam. These are not the sort of hopes upon which to base lock/float strategy.
