Portfolio analytics

For the following example, we utilize the Barclays Capital Portfolio Analytics System XQA, which incorporates the aforementioned multifactor model. Again, this model incorporates factors that include points on the yield curve as well as factors related to credit spreads. We took the yield curve data in the sterling model from gilts and for the euro model from Bunds. The credit spread factors consist of buckets by sector and rating, among other factors. 

Scenario analysis is illustrated in Exhibits 25.11, 25.12, 25.13, and 25.14 using Barclays Capital Portfolio Analytics System XQA. 

Portfolio management concepts have been an accepted component of the financial services realm for decades, and the need to diversify risk continues to be an effective organizing principle for many financial instruments and analytic techniques. Risk assessment is also a key component in the pharmaceutical world, where as few as 1 in 5000 laboratory-tested compounds ever makes it to the market. As such, the pipeline portfolio is a critical indicator of the future of a pharmaceutical firm, and the process of analyzing and managing it effectively is of vital strategic importance. 

Their conclusions were that many pharmaceuticals would degrade to innocuous substances but that degradation testing should take place as part of the portfolio of drug testing and also that analytical methods available at the time were inadequate to measure the expected concentrations of pharmaceuticals in the environmental matrices concerned. 

Chapter 4 covers the site selection and site controlling phase. Consequently, it deals with the assessment of individual production sites based on primarily qualitative criteria. Alternative Multiple Attribute Decision Analysis methods are reviewed and a decision support model employing the Analytic Hierarchy Process, which can be used both for site selection problems and as a controlling tool to perform site portfolio rankings of entire production networks, is proposed. Experiences from application in industry are reported. 

Procedurally the R D Manager will have to decide, after consulting the relevant staff, what analytical support will be required for each project in the portfolio for the coming period. Following discussions with the analytical services manager, the cost and availability of in house provision can be determined. Analytical services should be able to provide advice on where to get the most economical external provision of non-available analytical support. 

Materials (ASTM).94 In addition, the National Renewable Energy Laboratory95 (NREL) has developed and validated a collection of standard laboratory analytical procedures specifically for the compositional analysis of biomass including, but going beyond those of the ASTM. These wet chemical methods of analysis are based on the fractionation of the biomass sample and the isolation of purified fractions that can be quantified using conventional analytical instruments.96 These methods are primarily used in feedstock-specific portfolios containing analysis methods for each of the relevant constituents. In most cases, these portfolios enable the identification and quantification of greater than 95 percent of the dry mass of biomass feedstock and biomass-derived materials. 

Within each portfolio, the sequence of application of the various analytical methods is critical, as many methods have been validated with the assumption that all prior steps have been followed. For feedstocks, the sequence is sample preparation, then removal of nonstructural... 

No source was more valuable than Hoover s Handbooks, produced annually since 1990 for both American and non-American companies. Bach handbook includes a ten-year review of the companies financial statistics and a portfolio of their major product lines, with percentage of sales and income from these lines as well as a brief resume of their history. Hoover s Handbooks certainly remain a reliable basic source for business and economic historians to carry out their central analytical tasks.

Duarte also proposes a generalized approach to asset allocation that includes mean semi-variance, mean absolute deviation, MV, and value-at-risk as special cases. While cleverly broad, Duarte s method relies on simulation teclmiques and is computationally burdensome. In addition, because simulation approaches do not have explicit analytical solutions, the technique loses some of the precision of MV analysis. For example, one can examine solution sensitivities from the second-order conditions of MV problems, but this is not so easy with the simulation. It remains to be seen whether simulation approaches receive widespread acceptance for solving portfolio problems. Nonetheless, simulation techniques offer tremendous potential for future applications. 

This chapter has presented a brief introduction to asset management, focusing on primary applications. The basic analytical tool for portfolio analysis has been and remains MV analysis and variants of the technique. Mean-variance an ysis is intellectuedly deep, has an intuitive theoretical foundation, and is mathematically efficient. Virtutilly all asset-management problems are solved using the approach or modified versions of it. 

Simply analyzing the individual credits and averaging their individual probabilities of loss is likely to understate the actual losses that will occur across the portfolio because certain factors, whether macroeconomic, sector-specific, or otherwise, are likely to impact more than one credit simultaneously. A variety of institutions use proprietary analytic methods (i.e., Monte Carlo based simulation techniques) to explore correlation assumptions in light of these factors.
