That is, in this case there are gains from diversification. Because these payoffs or returns are random except for the risk free asset , tomorrow’s wealth will also be random. A qualification to this analysis is in order. Thus, if you believe in mean reversion and you are more risk averse than a log wealth investor, you would rationally increase your exposure to risk and your investment horizon expands.

In this course, we will discuss fundamental principles of trading off risk and return, portfolio optimization, and security pricing. We will study and use risk-return models such cohld the Capital Asset Pricing Model CAPM and multi-factor models to evaluate the performance of various securities and portfolios. Building upon this framework, market efficiency and its implications for patterns in stock returns and the yoj industry will be discussed. Finally, the course will conclude by connecting investment finance with corporate finance by utiloty firm valuation techniques such as the use of market multiples and discounted cash flow analysis. The course emphasizes real-world examples and applications in Excel. The over-arching goals of this course are to build an understanding of the fundamentals of investment finance and provide an ability to implement key asset-pricing models and firm-valuation techniques in real-world situations.

The CFO is deeply involved in financial policy and corporate planning. Often he or she will have general managerial responsibilities beyond strictly financial issues and may also be a member of the board of directors. The controller or CFO is responsible for organizing and supervising the capital budgeting process. However, major capital investment projects are so closely tied to plans for product development, production, and marketing that managers from these areas are inevitably drawn into planning and analyzing the projects. If the firm has staff members specializing in corporate planning, they too are naturally involved in capital budgeting.
In particular we employ two key assumptions:. The following graphs tells the story. A strategy involving short positions may require that additional capital be pledged to cover possible shortfalls between ending asset and liability values. We can calculate the expected return and the standard deviation on this new portfolio. But caution should be taken in judging a model by its assumptions. The possible wealth values are computed by linking all possible inveest of return. The dispersion of wealth thus expands around a growing mean as the investment horizon lengthens, or as the number of independent risky ventures increases.
