After strong used pickup prices contributed to wholesale prices rising in the lanes in October, the tides quickly turned this month as seasonality is taking its toll.

During the first week of November, truck prices took the biggest hit seen this year — and last week, prices took another hefty plunge.

According to the latest Black Book Market Insights report, trucks experienced one of the largest price declines this year in the lanes last week, with prices falling by approximately 0.80 or $125.

Black Book editors pointed that out seasonality is contributing to price drops among both cars and trucks, but it is interesting that truck declines are occurring while gas prices remain low at an average of $2.22 per gallon nationally.

“Gas prices are remaining low, but no longer seem to be helping truck values that have been stronger than the values of car segments so far this year,” said Anil Goyal, vice president of automotive valuation and analytics.

The biggest declines in the truck segments were seen among the midsize SUVs (down 1.76 percent or $293), compact pickups (down 1.46 percent or $210) and the compact SUVs (down 1.18 percent or $229).

The best performing group was the midsize pickups, which saw a slight price increase of 0.10 percent or $11.

Illustrating the change in truck trends, Black Book editors head an auction attendee from Michigan noted, “Trucks are still doing well, but there are some soft spots showing up.”

The cars were experiencing the impact of seasonal lows, as well, as wholesale prices dropped by an average of 0.83 percent or $91 last week. Black Book reports this is higher than the average depreciation rate of 0.71 percent for cars seen over the previous four weeks.

Among the cars, the near luxury (down 1.16 percent or $187), luxury level (down 1.02 percent or $199) and the entry level (down 1.01 percent or $61) segments saw the biggest price drops last week.

The best performing car category on a percentage level was the premium sporty car segment, which experienced a 0.48 percent or $178 drop.

Leading up to November, trucks and SUVs had seen some of the strongest residuals in the industry this year.

According to ADESA Analytical Services’ monthly analysis of wholesale vehicle prices by model class, auction prices were up 1.1 percent last month when compared to September — and strong pricing among trucks had a direct impact on this movement.

In fact, according to the latest edition of Kontos Kommentary from ADESA Analytical Services’ Tom Kontos, this increase was driven largely by “upticks in truck prices.”

In October, wholesale prices for full-size pickups rose by 12.7 percent year-over-year to finish the month off at an average price of $14,469. Compact pickups saw rates spike by 6.5 percent from October 2014, coming in at an average of $7,793 last month.

Kontos explained that although pickups are out-performing the market, wholesale prices were still looking stable all around.

But as the industry approaches winter, it seems no segment is immune from the impact of seasonality.
