Though wholesale prices rose overall last month, according to Kelley Blue Book’s latest Blue Book Market Report, values for full-size pickup trucks are lagging behind the industry average.

This may come as a surprise, since  large truck segments showed very strong retention levels throughout 2013.

Much of this strength was due to a spike in home construction, but now the tides have turned.

According to KBB data, auction values for full-size pickups fell by 0.77 percent last month from January rates and were down 0.67 percent year-over-year.

And according to ADESA Analytical Services, the average wholesale price for full-size pickup trucks in February was $12,460, down from $12,632 in January.

This is contrary to overall trends, as auction values rose this past month, hitting an average of $17,970, which is just $27 less than last year’s February average, according to KBB.

Though some of that decline may be due in part to seasonal patterns, “slower construction may lengthen the perid of lower values and dampen the expected increase in values during the coming months,” KBB analysts explained.

Backing up these claims, according to the report, permits authorized for new privately owned housing units in January were 5.4 percent lower than December 2013 and 2.4 percent below January 2013.

On the same note, construction starts for privately owns units in January were 16 percent lower than December 2013 and 2 percent lower than the same period of 2013.

KBB predicts that if construction continues to slow, values for full-size pickups should continue to drop.

In fact, KBB predicts these trends will impact full-size pickup rates so much that this segment is not expected to see a strong price resurgence this spring, even amid tax season highs.
