The Dow Jones Industrial Average surged 631.86 points in the last three hours of trading yesterday as traders piled into equities.

Fueling the rally? The bond market.

For as much as stocks gained today, bonds lost. Including mortgage bonds. The dramatic sell-off created a huge swing in mortgage rates and erased nearly all of 2008's rate improvements.

This is one reason why it pays to be aware of your home loan. That way, when markets change and a doorway to payment reduction opens, you can quickly step through it.

As yesterday illustrated, with mortgage rates, opportunity is often fleeting.

With stocks poised to rise again today, it should likely happen at the expense of bonds. Mortgage rates are trending higher, too.
