Investment risk

Introduction

Unit image

A fair return on investment is defined as one that compensates the investor for the risk incurred in making the investment – neither more nor less. Conversely, an excess return is one that over-compensates the investor for the risk incurred. Investors want to avoid investments that pay less than a fair return, while borrowers want to avoid paying an excess return. In this unit we shall:

  • define more precisely what we mean by ‘risk’ in a financial context;

  • consider how investors react to the presence or threat of risk;

  • develop a method of quantifying risk mathematically; and

  • look at the main factors contributing to investment risk in the real world.

Finally, we shall see how the use of the net present value rule enables investors to calculate whether the risks they incur are adequately rewarded.
