The percent change for the week and the dot color are based on two different metrics.
1. The dots are based on TREND. The dot color might be red because the vehicle is in a DOWN TREND.
2. The weekly percent changes reflect Mon-Fri., or 5 trading days data.
The percent change for the WEEK could be positive so that number would be green. Of course the opposite is also true —- your vehicle is in a positive, UP trend but the change for the week was negative so the number on the right is RED. Often times they are not the same color. Focus on the DOTS.
