Berk and Green (2004) make a theoretical argument that performance persistence should not exist since new money flows into well-performing mutual funds and there are diseconomies of scale, or because successful funds capture excess returns by raising fees. We find that performance prediction continues when we examine samples of larger and larger funds and that past performance predicts future performance for holding periods up to three years. Funds that outperform index funds of the same risk can be identified. We find that expense ratios are lower for large funds, and decrease as funds get larger or perform well.

As a result of poor asset allocation decisions by 401(k) participants, 72% of all plans now offer target date funds, and participants heavily invest in them. Here, we study the characteristics and performance of TDFs, providing a unique view by employing data on TDFs holdings. We show that additional expenses charged by TDFs are largely offset by the low-cost share classes they hold, not normally open to their investors. Additionally, TDFs are very active in their allocation decisions and increasingly bet on nonstandard asset classes. However, TDFs do not earn alpha from timing or their selection of individual assets. (JEL G11. G23.)

examining the reasonableness and accuracy of investment advice. Topics such as earnings estimates, security analysts recommendations, and recommendations for selecting mutual funds have been studied extensively. However, almost no attention has been paid to examining advice about the asset allocation decision (the allocation of funds across broad classes of assets). This is surprising because the asset allocation decision has been recognized as a major determinant of return and risk and because of this, advice on the optional allocation decision is provided by most brokerage firms and investment advisors Given the importance of the asset allocation decision we anticipate that the rationality of asset allocation advice will be extensively examined. The purpose of the article is two fold. First, we will examine modern portfolio theory to see what we can learn about the general characteristics of advice that are necessary for consistency with theory. Second, we will examine the advice of some specific investment advisors to see if their advice is consistent with rational behavior. We proceed in three steps. We first review some of the basic tenets of MPT, discuss alternative formulations of the problem, and examine which formulation is appropriate and

One of the major problems in finance is that of combining the separate costs of debt and equity into an appropriate cutoff rate for new investment; this problem is particularly acute when the firm is changing its capital structure. Solutions to this problem which have been proposed include various types of both marginal costing and average costing.
