Use Weekly VMT to Predict Retail Impact
Since vehicle miles traveled (VMT) is a leading indicator of aftermarket activity, did Americans take road trips during Independence Day weekend? The America Automobile Association predicted that nearly 44 million Americans would gravel by automobile for the holiday, 5.1% more than in 2019, and 34.1% more than in 2020 (AAA, June 22, 2021)
What actually happened?Relative to previous years, VMT for the two-week period around July 4, 2021 was higher than for the same time period in 2019 and 2020.
This confirms that not only was there pent-up demand to travel, but that travel for July 4 weekend via automobile in 2021 exceeded the past two years. Just as interesting, VMT for the weeks of June 27 and July 4, 2021 were comparable to previous weeks, illustrated below.
So, what?Intuitively, we know that VMT correlates with vehicle maintenance and related sales … but by how much? Auto Care Association members can use TrendLensTM to compare two industry indicators and can instantly see the level of correlation. In the chart below, monthly VMT (vehicle miles traveled, orange) is plotted against retail sales for automotive parts, accessories, and tire stores (gray) from January 2019 through June 2021. These indicators are moderately correlated: the Pearson correlation coefficient for these two variables is 0.55 (displayed in the upper left, a new TrendLensTM feature), denoting a moderate positive correlation – this means that they generally rise and fall together.
The next figure illustrates disposable income (orange) against retail sales of automotive parts, accessories, and tire stores (gray) from January 2018 through June 2021. These indicators are more strongly correlated, with a Pearson correlation coefficient of 0.85.
What’s in it for me?Tracking variables that you know to be leading indicators for industry activity (demand for parts and service) can give you time to anticipate consumer behavior and stock products / staff resources accordingly.
