composition of the entire portfolio, which is the major determinant of overall

performance. Moreover, top-down management is the natural way to establish a

high returns that could result from identifying and concentrating in undervalued

securities or sectors of the market.

With a “bottom-up” investing style, you try to benefit from identifying undervalued securities. The disadvantage is that you tend to overlook the overall composition of your portfolio, which may result in a non-diversified portfolio or a portfolio with a risk level inconsistent with your level of risk tolerance. In addition, this technique tends to require more active management, thus generating more transaction costs. Finally, your analysis may be incorrect, in which case you will have fruitlessly expended effort and money attempting to beat a simple buy-and-hold strategy.

assume risk. Traders will share in the upside potential directly but only in the

downside indirectly (poor performance = potential job loss). Shareholders, by

contrast, are affected directly by both the upside and downside potential of risk.

19. Answers may vary, however, students should touch on the following: increased

transparency, regulations to promote capital adequacy by increasing the frequency of gain or loss settlement, incentives to discourage excessive risk taking, and the

promotion of more accurate and unbiased risk assessment.
