LAWRENCEVILLE, Ga. -

Halloween is less than two weeks away, and dealers might be thinking they’re getting tricked since it doesn’t appear to be much of a treat for them in the lanes this fall.

Black Book described the unusual pricing landscape that’s continues to be seen in the wholesale market, as overall values rose for the seventh week in a row with all vehicle segments moving higher.

“Traditionally, values would be declining this time of year, but the lack of inventory continues to be the most common sentiment for the increased auction activity, pushing values up,” analysts said in the latest installment of Market Insights released on Tuesday.

On a volume-weighted basis, Black Book said overall car segment values increased 0.67%.

Analysts noted that prices for midsize cars jumped 1.11%, marking the ninth week in a row of an increase.

Black Book pointed out that even with the weather cooling, values of sporty cars rose for the third consecutive week, climbing another 0.34%. By comparison, analysts indicated values of sporty cars declined by 0.32% during the same week last year.

Meanwhile, Black Book’s volume-weighted truck data showed that overall values increased 0.58% with seven of the 13 segments posting price gains higher than the overall reading.

Analysts said values for subcompact luxury SUVs jumped the most at 1.06%, marking the eighth week in a row of increases for the segment.

Black Book added that prices for full-size pickups have now rise 29 out of the past 39 weeks with an average weekly increase of 0.38%.
