You can’t calculate derivative of a discrete function. That’s why we talk about trends. These tend to include more than last 2 data points, because of noise.

- xyzzyz 2y agoThe weak derivative does not have much to do with any trend of a function at a point. The value of weak derivative at any given point is not even defined. The weak derivative of a quarterly earnings function is zero, regardless of what the earnings actually are. I hope you realize how silly you are being here.
