Is there a term that better describes a compound annual growth rate (CAGR) when it is negative?
Not sure why CAGR is a problem for both directions. I used to be a physicist, and, when I taught classes in graduate school, students always wanted to use the terms "accelerate" and "decelerate" to describe "speeding up" and "slowing down". But acceleration is just a vector with magnitude and direction. There's nothing special about slowing down that it needs a special name. It's just acceleration in a direction opposite to the direction of motion. I think the same thing applies here. There's nothing special about negative growth rates that they need a special name. Just stick a minus sign in front of the number and you convey the required information.
