Ex ante is the projection before the event and ex post is the output after the event. Companies may use them together by comparing the actual data with the projected data. This comparison is done so that businesses can take corrective measures and avoid past mistakes in devising future strategies. Companies compare their current income sheets, balance sheets, and other financial data (ex-post data) with the ones that were projected by them. By comparing these data, they are able to evaluate their company’s actual performance after the decision is made or after the event happens. Investors may compare the predicted returns of an investment with the actual returns in order to make better investment or purchase decisions in the future.
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. This is common for earnings reports and other major events like mergers.
