The April Case-Shiller home price data came out this morning and the second derivative continues to be slightly positive.
April prices were down 18.1% y/y vs. 18.7% in March and 19% in January, according to Bloomberg. You can see the far right data points turning higher.
While large improvements are not likely until the jobs market improves, I'm a believer that the bottom is being put in. The woes in this economy are significant but the healing, if not outright improvement, continues.
