What is 'sensitivity analysis' in finance?

• A. A way to increase overall market investment
• B. A method to predict the outcome of a decision given a certain range of variables
• C. A strategy for diversifying investments
• D. A legal review of financial portfolios

Answer: (B)

Sensitivity analysis in finance is a method used to evaluate how the different values of an independent variable can impact a particular dependent variable under a given set of assumptions. This technique is particularly valuable in financial modeling and decision-making because it helps identify how sensitive the expected outcome of a financial decision is to changes in input variables or assumptions.

For example, in the context of a company’s financial projections, sensitivity analysis allows analysts to examine how changes in assumptions about sales growth, cost of goods sold, or operating expenses can affect the overall profitability or valuation of the company. By understanding these sensitivities, decision-makers can better assess risk and make more informed choices based on a range of possible scenarios rather than a single, static forecast.

The other choices do not accurately capture the essence of sensitivity analysis. Increasing overall market investment refers to broad market strategies rather than individual financial modeling. Diversifying investments relates to spreading out risk among various assets rather than analyzing variable impacts on financial outcomes. A legal review of financial portfolios focuses on compliance and legal aspects rather than the analytical assessment of financial variables.
