Which Portfolio Application Tab enables the calculation of variance between two scenarios?

The Reports tab is the correct choice for enabling the calculation of variance between two scenarios within Argus Enterprise. This tab typically includes a range of analytical tools and outputs that allow users to compare various performance metrics from different scenarios. Variance analysis is a crucial aspect of financial modeling, as it helps users understand the differences between expected and actual performance, or between different predictive models.

In the context of Argus Enterprise, after setting up different scenarios—such as base case and alternative case—users can generate reports that detail the variances across specific parameters, enabling informed decision-making. This capability is essential for stakeholders who need to assess risk, forecast returns, and make strategic investment decisions based on comparative data.

Other tabs such as Properties focus on asset-level information, Portfolio Details typically summarize the overall portfolio characteristics, and Scenarios functionality is more about defining and managing various possible outcomes rather than providing direct comparative analyses. Therefore, the Reports tab is specifically designed to facilitate the calculation and presentation of variances, making it the best answer to the question.
