After the occurrence of a predicted event, the predicted outcome (ex-ante) can be compared to the actual outcome (ex-post). The ex-post information allows the investment company to evaluate how they actually performed as opposed to how well they planned to achieve the outcome. The actual outcome can also help the investor refine their prediction process and get additional insights on how to make the predictions closer to the actual outcome.

Types of Ex-Ante Analysis
When new regulations are imposed, sometimes pre-existing businesses are exempt and sometimes not. In accident law, negligent behaviour by the first actor may require the second actor to take action beyond the ordinarily efficient actions as can be seen in the doctrine of last clear chance. Rights typically go to the highest bidder, but at 4-way stop signs, rights are granted according to who was there first. In other areas involving traffic, being first accedes to other criteria such as majority rule.
In that manner, ex-post risk refers to risks that take place after the fact by accounting for historical returns as a base or guideline. It involves the analysis of actual historic return streams to ascertain the variability of that return stream over time. This kind of analysis looks at the risk of current portfolio holdings and estimates future return streams and their projected variability based upon statistical assumptions. An example of ex-ante analysis is when an investment company values a stock ex-ante and then compares the predicted results with the actual movement of the stock’s price. When the predicted event (ex-ante) occurs, analysts can compare the actual outcome (ex-post) and the predicted outcome to see how accurate the prediction was.
The ex-post value of a security can be calculated by subtracting the price paid by investors from the security’s current market price. The ex-post value of an asset is determined by adding the asset’s beginning and ending values over a given time period. Ex-ante analysis refers to the prediction of an event before it actually happens, or before the participants of that event become aware of the facts.
For example, she may analyze the overall economic climate and whether the company’s business operation costs might be affected by it. She may also use past business decisions and earnings statements to hypothesize about the company’s sales figures. It’s often impossible to account for all the variables for every form of ex-ante analysis. That’s why price targets that account for many fundamental variables sometimes miss the mark due to exogenous market shocks that affect nearly all stocks. While all forecasting is ex-ante, some analysis still involves analysis immediately after an event takes place. For example, there’s often considerable uncertainty related to fundamental company performance following a merger.
Ex-Post Forecasting
In order to conduct the ex-post analysis, it’s important to choose the type of asset class in question, then use regression analysis to figure out the potential for gains or losses. For example, if the Fed raises interest rates, we can only know if the decision was right or wrong when the predicted outcome happens. If the increased interest rates and global recession pushed the economy into inflation, it might mean that raising the interest rates was a wrong decision. However, if the economy is still stable and performing above board three to five years later, it means that the Fed’s decision to raise interest rates was appropriate and timely.
- Ex-ante predictions can also be made when a merger is expected to be initiated.
- Analysts and investors can use any historic returns to make predictions about the future performance of investments and companies.
- These experts break down and compare revenue streams and determine how compatible they are with one another.

- It is the interest rate quoted on loans and bonds, and it does not adjust for the rate of inflation.
- Ex-ante and Ex-post are Latin terminologies used in predicting the returns of a security.
One of the key factors about the ex-ante interest rate is that it isn’t adjusted for inflation. First, let’s suppose Company ABC is expected to report earnings on a certain date. An analyst at a research firm will use economic and financial data from its past and present operating conditions to make a prediction regarding its EPS.
Understanding Ex-Post Risk
As the name implies, an ex-ante interest rate is one that is determined before the actual interest rate is announced. So if you pay $10 interest on a $100 loan, you’re paying 10% in interest. Keep in mind, though, that the ex-ante rate isn’t adjusted for inflation. The term ex-ante interest rate refers to the real interest rate calculated before the actual rate is revealed. The ex-ante interest rate is what lenders and bond issuers publish for loans and bonds.
Let’s say the central government of a country makes an ex-ante prediction on the inflation of the country, and there are chances that the inflation rate will increase shortly. The prediction can be of a business’s specific good or commodity, a business unit, or the complete corporate entity. It is imaginary (intended), in which a firm assumes the level of investment on its own. For full access to this pdf, sign in to an existing account, or purchase an annual subscription.

Ex-ante is a Latin word that means “before the event.” The term is commonly used in financial markets to refer to the prediction of events such as economic and financial parameters. It attempts to determine an investor’s maximum amount of loss for an investment over a specific period of time within a certain degree of probability. Remember that ex-post risk refers to a way to measure how much risk comes with a certain investment by accounting for its past returns. Ex-post analysis is a way to analyze any information related to an investment’s earnings and price changes that take place after the fact to determine the potential for returns. A related but opposite term is an ex-ante risk, which refers to the future projected risks of a portfolio. This means that the outcome must be predicted before it actually takes place, making it uncertain.

The actual or realized investment, on the other hand, Ex-post or actual investment is the measurement of a time (e.g., a year) after the fact, when more investment is required. It should be emphasized that Keynes included stocks of unsold products in his investment calculations. To put it another way, an ex-ante investment is one that is planned or wanted before it is made, whereas an ex-post investment is one that is made after it has been made. As a result, the real investment may differ from planned investment due to unforeseen inventory additions or reductions (stock of goods). This component of ex-ante and ex-post investment is taken into account while determining National Income.

By making the prediction of the outcome, the obtained ex-ante value can then be compared to the actual performance when it happens. Investors can use the ex-post data to get the actual performance of a security, without including any forecasts or projections that may be affected by market shocks. The ex-post value of a security can be obtained by deducting the price paid by investors from the current market price of the security. Unlike ex-ante, which is based on estimated returns, ex-post represents the actual results attained by the company, which is the return earned by the company’s investors.
The difference between the two outcomes can provide additional insights on how to streamline the prediction process to make it near-accurate. It also helps the analysts to analyze how well they performed compared to the outcome they originally planned to achieve. The ex-post investment is the investment of a period [e.g., a difference between ex ante and ex post investment year] that is measured after the fact. It’s important to remember that sometimes investments are made that weren’t originally planned or intended. When unsold completed items amass owing to low sales, unplanned investment occurs. As a result, an economy’s real investment is the sum of planned and unanticipated investments.

- Ex-post savings and ex-post investment are always equal at any level of income.
- Predicting the expected returns of a security or investment is often a difficult task, especially due to the unpredictability of the market.

After this, an evaluation of the changes in the value and the revenue generated by the asset is done. If the inflation will be stable after a certain period, that means the policy was appropriate.
When transcribed from Latin, ex-ante is the prediction of a particular event in the future, such as the potential returns of a company. Ex-ante predictions are often inaccurate since it is impossible to account for variables, which are affected by market forces of supply and demand. Ex-ante investment refers to the investment that enterprises and planners in the economy wish to make at the start of a period.
Ex-ante is a Latin term meaning “before the event” It is the anticipated return on an investment or the earnings that an individual expects at the end of a given period. However, economists (such as Krugman) are critical of the decision to raise interest rates. Typically, access is provided across an institutional network to a range of IP addresses. This authentication occurs automatically, and it is not possible to sign out of an IP authenticated account. In finance, this refers to anything that occurs before market participants become aware of the pertinent facts.
Ex-post yield differs from ex-ante yield because it represents actual values, essentially what investors earn rather than estimated values. Investors base their decisions on expected returns versus actual returns, which is an important aspect of an investment’s risk analysis. It shows the performance of an asset; however, it excludes projections and probabilities. There are many different ways for investors and companies to make important decisions about their investments. One of the most common ways to do so is by conducting or reviewing ex-ante analysis. This type of research is done using forecasting by taking historical returns and performance into account.
To measure a security’s returns from 1st January to 31st March, we will calculate the difference between the opening (price on 1st January) and closing price (price on 31st March). For example, if the value obtained is +6%, the assets have appreciated 6% since 1st January. However, it will only be in one or two years, whether we will be able to tell whether the decision was correct. For example, if this interest rate, combined with the global recession, pushes the US economy back into recession, the ex ante analysis of raising rates may prove it to be the wrong decision. There is an example of ex ante and ex post in this blog from Paul Krugman below about the decision of the Fed to raise interest rates.
