The term "ex-post" refers to a situation where events have already occurred and are therefore known. In financial analysis, ex-post refers to an investment's actual return, as opposed to its expected return. An investment's ex-post return is useful in assessing whether the investment performed better or worse than expected. What is ex-post measure? Ex-post measure is a statistical measure that is used to assess the performance of a financial asset or portfolio after the fact. This measure can be used to evaluate the performance of a security or investment over a specific period of time, or to compare the performance of different securities or investments.
What is an example of ex post facto?
An ex post facto law is a law that is retroactively applied, that is, a law that is enacted after the fact. This can have the effect of criminalizing conduct that was not illegal at the time it was committed. For example, if a law is enacted making it a crime to drive over the speed limit, and someone is caught driving over the speed limit, they can be prosecuted for the crime even though it was not a crime at the time they committed it.
What is the difference between ex-ante and ex-post investment?
The main difference between ex-ante and ex-post investment is that ex-ante investment refers to the investment that is made before the project or activity takes place, while ex-post investment is the investment that is made after the project or activity has taken place.
Ex-ante investment is typically based on forecasted data and expected outcomes, while ex-post investment is based on actual data and outcomes. As a result, ex-ante investment is often considered to be more risky than ex-post investment.
Another key difference between the two types of investment is that ex-ante investment can be used to finance the project or activity upfront, while ex-post investment is typically used to finance the project or activity after it has already been completed.
Finally, it is important to note that both ex-ante and ex-post investment can be used to finance a project or activity, but they are typically used for different purposes. Ex-ante investment is typically used to finance the initial stages of a project or activity, while ex-post investment is typically used to finance the final stages of a project or activity.
What is ex post saving? The term "ex post saving" refers to the amount of money that a person or household saves after all expenses have been paid.

Ex post saving can be a useful metric for measuring financial well-being, as it provides a snapshot of a person's or household's ability to save after all necessary expenses have been covered.
