Quote from scriabinop23:
Let's repeat: The value of an asset is the present value of all of its future cash flows.
That means it has nothing to do with the past. Not 'little', but nothing. PAST = meaningless.
Not true in practice.
In order to get a present value, you need future cash flows and a discount rate. Future cash flows are usually based on prior data, although they can sometimes be completely projected. Discount rates are almost always based on prior data or existing data, the PAST.
