This week’s Black Book Market Insights report shows how smaller and mid-size car segments are continuing to lead with some of the largest depreciation rates seen in a while. Sub-compacts in particular have demonstrated significant depreciation over the last four weeks at -2.87%.

“Fuel prices moved down slightly and Truck & SUV demand remains high. Nonetheless, weekly depreciation rates are weighed down by ample wholesale volume and seasonality,” said Anil Goyal, senior vice president of automotive valuation and analytics.

According to the report, here are other key stats:

• Volume-weighted, overall car values decreased 0.54% last week. That’s the highest overall weekly deprecation rate since the first week of 2016.

• Compact and Mid-size Car segments received the highest weekly depreciation rates at -0.83% and -0.81%, respectively.

• In the last month, the Sub-compact segment led depreciation rates at an accumulative adjustment of -2.87%, followed closely by the Compact Cars at -2.83% and Mid-size Cars at -2.39%.

• Volume-weighted, overall truck values decreased 0.37% last week, same as the week prior. That’s two consecutive weekly high depreciation rates in the last three months.

• Compact Luxury Crossover/SUV, Compact Van and Mid-size Luxury Crossover/SUV segments received the highest weekly depreciation rates at -0.79%, -0.70% and -0.67%, respectively.
