Answer: the company’s market value of equity only.

## Explanation **Correct Answer: B** **Key Concepts:** 1. **Book Value of Equity** represents the historical accounting value of shareholders' equity based on the balance sheet (Assets - Liabilities). It is not immediately affected by earnings forecasts. 2. **Market Value of Equity** represents the current market price of the company's shares, which is forward-looking and reflects investor expectations about future earnings. **Why B is Correct:** - An unexpected improvement in earnings forecast provides new information about the company's future profitability. - This information immediately affects investor expectations, leading to changes in stock prices and thus the market value of equity. - Book value of equity only changes when actual earnings are realized and retained earnings increase, or through other accounting transactions - not from forecasts. **Why A and C are Incorrect:** - **A (Book value only)**: Book value is based on historical accounting data and doesn't change with forecasts. - **C (Both)**: Book value doesn't change immediately with earnings forecasts; only market value does. **Additional Context:** - Market value reflects investor sentiment and future expectations, while book value is based on historical cost accounting. - This distinction is fundamental in financial statement analysis and equity valuation.
