New home sales come out on Monday. Pay particular attention to the inventory levels -- especially the raw numbers. The total available inventory increased 2.68% from January 2006 - 2007, from 522,000 to 536,000. It's going to be awhile before the big drop in new home construction starts to decrease this inventory.
Bernanke speaks on Wednesday and Friday. Pay very close attention to what he says about inflation. His speeches are available online at the Federal Reserve site.
