Since 2008, Risk‐Reward Views have been the basis for the recommendations on all the stocks covered by Morgan Stanley's equity research analysts globally. The firm's analysts use this systematic approach to communicate a broader range of fundamental insights about expected returns and risks, and to articulate more clearly the logic underlying their price targets and calls, and the level of conviction associated with them. The rationale for this approach is to align the firm's research product with its clients' thinking and investment discipline while also creating a link between traditional equity analysis and widely accepted principles of modern portfolio management. Too many sell‐side analysts still try to manifest expertise and conviction with one‐sided investment theses backed by single‐point estimates and “table pounding.” That does a disservice to investors who are looking to sell‐side analysts for an ongoing dialogue about the future with experts on company fundamentals. Risk‐Reward Views are designed to produce a more complete view of the risk‐reward trade‐off in a given stock. They are meant to supplement the use of quant‐only risk models that, while offering at least the illusion of precision, are also often opaque and backward looking. The approach aims to increase transparency while avoiding unnecessary complexity by focusing on a handful of critical uncertainties and modeling a manageable number of coherent scenarios that are relevant to investor debates and cover a full range of plausible outcomes. This article focuses on the theoretical underpinnings of the department's Risk‐Reward initiative. For a more detailed discussion of the institutional setting and the processes followed to implement these ideas, readers are referred to the recently published Harvard Business School case study, “The Risk‐Reward Framework at Morgan Stanley Research” (Harvard Business School Case N9–111–011). 相似文献

Informal settlements in Natal are discussed. The need for and the reasons against informal settlement are examined. Means of overcoming the shortcomings of informal settlement are suggested and the need for security of tenure in order to promote ‘self‐help’ is highlighted. 相似文献

In recent decades there has been a well‐documented increase in organisations' use of formal tests for selection purposes. This article investigates whether tests' technical qualities and predictive validity are the critical determinants of take‐up, or whether other organisational and contextual factors are more important. Case studies of organisations were used to identify the factors driving change and Workplace Employee Relations Survey data were analysed to determine the consistency of the findings with national data. The single most important factor appears to be the regulatory environment, with tests used as a precautionary measure to protect selection decisions from challenge. The growing formal professionalisation of HR departments is also important, and the influence of both factors is consistent with current theories of organisational decision‐making. Continued growth in test use is likely, but the implications for efficiency in selection are less clear. 相似文献

We derive the sampling variances of generalized entropy and Atkinson indices when estimated from complex survey data, and show how they can be calculated straightforwardly using widely available software. We also show that, when the same approach is used to derive variance formulae for the independent and identically distributed case, it leads to estimators that are simpler than those proposed before. Both cases are illustrated with a comparison of income inequality in Britain and Germany. 相似文献

This paper expresses the results of an investigation of the influence of tobacco advertising on children's smoking. The investigation examined the existing body of evidence and literature on the subject including data obtained from empirical research carried out by the Children's Research Unit in London. Despite the speculation regarding the possible role of advertising in juvenile smoking, no evidence was found to link juvenile smoking initiation with tobacco advertising. On the contrary, the evidence suggests that smoking initiation is more dependent on family smoking behaviour and peer pressures. These factors emerged consistently as the major influences in smoking initiation throughout the literature and the range of countries investigated regardless of the extent of tobacco advertising permitted in each country. Advertising is not as influential as is often supposed. Psychological filter systems are employed by the consumer, who selects only that information which is of relevance or interest to him. Widespread awareness of the tobacco-health issue means that an additional barrier is formed in the case of cigarette advertisements. There is no evidence that tobacco advertising influences non-smokers (either children or adults) to take up smoking. 相似文献
