I just need a few sentences for these two questions below. No need for APL formation, just a discussion. TIA. 1. We often use a version of the perpetuity formula to value stock. That is, we consider a company as a “going concern” operating without an expected end, and paying out earnings to investors. A perpetuity is a constant stream of cash flows without end. Why doesn’t it have an infinite value? (Stocks do not have an infinite value). Under what cases can we easily calculate a perpetuity or stock’s value?
