Review Questions

• How does the cost of common equity influence a company's investment decisions?
  • The cost of common equity directly affects a company's decision-making regarding investments and projects. If a potential project's return exceeds the cost of common equity, it may be considered viable and attractive for funding. Conversely, if the projected return is less than the cost, the project may not be pursued, as it would not adequately compensate investors for the risk involved.
• Discuss how changes in market conditions can impact the cost of common equity for a company.
  • Changes in market conditions can significantly impact the cost of common equity by altering investor perceptions of risk. For example, during economic downturns or increased volatility, investors may demand higher returns to compensate for perceived risks associated with holding equity. This can lead to an increase in the cost of common equity, which may cause companies to reevaluate their investment strategies and project viability.
